The Different Kinds of Air Ducts and Insulation Solutions that are Used in HVAC Units

The HVAC or the Heating, Ventilation and Air Conditioning units use the air ducts for distributing air. The air ducts solutions include the air processing units, air supply, air return, air diffusers and extraction columns among other solutions. The qualities of the air duct in the way displays the quality of the installation. Apart from providing for air flow, they also provide for other benefits including energy savings and acoustic or noise-related properties of a system.

There are broadly 4 kinds of ducting used today. These include the metal, glass wool, plastic and flexible ducts.

Metal Ducts
Stainless steel ducting manufacturers provide high quality metal ducts made of galvanized or stainless steel. Copper and aluminum are also used. They are then cut and shaped to suit the precise configurations of a building’s air distribution HVAC system. Metals are always good conductors of heat, and hence, these metal systems require a thermal insulation. Glass wool is a common material used for the purpose and is available in roll form (also called as wrapped insulation). The wool is wrapped in and around the outer duct. The wrap consists of an inbuilt aluminum foil face that resists the vapor flow. Sometimes the insulation material is also installed within the inner walls of a duct, and these are termed as duct line. They provide more strength to the inner duct side while also providing for acoustic insulation.

The metal sheets may be classified on the basis of different parameters. They can be classified according to the greatest pressure that they can sustain or withstand. They are classified according to the degree of air-tightness that they can provide.

Glass Wool Duct Boards
These ducts are made using the high-density glass wool board. The boards are cut and folded by the stainless steel ducting manufacturers and installers to fit the required configurations and geometry of the duct system created.

Plastic Ducts
These ducts are made from foam or plastic. The materials are cut and folded to create the required geometrical configurations. They often employ an external and internal aluminum coating.

Flexible Ducts
These duct systems consist of polyester and aluminum tubes that are concentric with each other. Thermal insulation is provided by inserting a glass-wool layer in-between the 2 tubes.

Air conditioning companies in UAE use the highly reliable steel and other systems on the basis of their suitability, and on the basis of the budget of the client.

Why You should always Use the Certified Lifting Equipments

Any lifting equipment in UAE must have been certified, as certification ensures that the lifting equipment is reliable and secure. One certification is the “Engineering Approval” and this approves and rates the capacity of the equipment. The other certification is done annually and inspects the welding of the product. Many types of equipment are often not certified, but the construction and architecture industry is gradually moving towards better policing of the standards.

Here is some reason why is it very important to have certified lifting equipment in UAE:

Law regulations
Different countries have their own set of provisions and guidelines, and these are made so that only those equipments are used that bear the professionals seal. All equipments must have the document that shows and outlines the loading scenarios and other rating information so that the capacity of the equipment is clearly expressed. The codes also call for the yearly inspection of the equipment by an expert and certified professional.

Safety
A certified lifting equipment is structurally sound for its given rating. Use of certified equipment brings in the peace of mind for the supervisors and managers. Only a certified and yearly inspected equipment is safe for being used yearly, in a continued manner. 

Quality Control
Almost all of the times, certifications also involve the quality control review of the equipment. Following of the codes and the guidelines ensure that only qualified welders have been employed for fabricating the equipment, and well-laid welding procedures have been followed.

Liability
It is the job of the operator to see to it that the equipment is certified, and the job of the engineer to ensure the safety of the device. Hence, there is no liability on the part of the users if a misadventure happens, and there is a well-laid procedure for the misadventure. The liability hence decreases manifold, and the risks also fall.

Un-certified lifting equipment is often a cause of the disaster. If the equipment used are not tested, a disaster is waiting to happen nearby. You must always ensure that you are using high-quality lifting equipment, as they carry immense loads, and an accident may result in severe adverse consequences. MEP contracting company in UAE also provide well-certified lifting equipment in UAE, and there are also other sources of getting the certified equipments.

Why APLACO CPVC Fittings are often Preferred over Copper Pipes

There have been many instances lately where both home owners and building contractors are taking to APLACO CPVC fittings and pipe systems over copper pipes and fittings. In a place where AC companies charge a lot for the installation of HVAC systems, there are many good reasons why this affordable trend might be overtaking the market. 

APLACO CPVC fittings and pipes are chlorinated polyvinyl pipes that are some of the most widely used pipes in the whole world. Not only are these pipes among the top choices for builders, owners, and contractors alike, but they are also used in a variety of applications throughout the majority of industries.

The reasons for the popularity of CPVC pipes and fittings are exceedingly clear. Chlorinated polyvinyl pipes offer several benefits to both the builder and the contractor by being very easy to install and join. These pipes offer a lot of ease and time saving benefits since joining two pipes together only requires some glue. The installation of CPVC piping is regulated and approved of by most building authorities and ministries. 

In recent times, CPVC has been used as a replacement for copper pipes that transport drinking water. CPVC is non reactive and non toxic, making it ideal for the transportation of water especially since the polymer is also able to withstand the flow of water at high temperatures until about 180 degrees Fahrenheit. The pipes are also fairly resilient and can handle a high flow and pressure system of water. 

CPVC is compatible with many different uses, which is evidenced by its wide use across the world. However, CPVC pipes cannot be used with a variety of chemicals which can alter the chemical composition of the pipe itself. In worst case scenarios, CPVC pipes can even explode from misuse. 

Apart from this one drawback, CPVC piping is considered by many to be better than copper piping because of its resistance to corrosion from climatic conditions, temperature, and water pressure. CPVC pipes and fittings are therefore the most popular ones used in the supply of water. 

CPVC piping is also a very cost effective piping system compared to almost all other pipe and fittings materials. Combined with all the other advantages of CPVC, it is easy to see why it is preferred to copper.

Call the Professionals when You Need Maintenance Work for Consumable Products in UAE

Although most people take the presence of their HVAC systems for granted, not all residents and workers have access to the heating and cooling benefits of such consumable products in UAE. Though having an air conditioning system in most parts of this region is a given, not all rooms or homes have them, even with rising climate conditions. Thus, an HVAC or air conditioning system becomes somewhat of a luxury. 

Most people will agree that having an air conditioning system in your home is an absolute necessity, and that not living in temperature controlled environments can affect your health and productivity. Even so, there is a small fraction of people who will purchase an HVAC system for their environment but still treat it as a luxury item. It is true that these systems are expensive, which is why many people turn to maintaining their systems themselves. Hiring good contractors and technicians for basic maintenance of consumable products in UAE is considered a luxury by the majority of people. In fact, people are reluctant even to turn to professional help when installing refrigeration equipments in UAE, for example. 

Although having strong DIY skills can save a lot of money in the long run, it cannot compete with the diagnostic tools and maintenance experience that skilled technicians have. A good HVAC or refrigerator contractor can take a good look at your equipment and not just fix any obvious problems, but also diagnose any underlying situations, as well as form an assessment of the workability of the rest of the components in the system.

A well experienced HVAC contractor can give you a list of maintenance you will have to have carried out (either by yourself or through a technician) and the time periods by which you will have to get it done by in order to prevent the occurrence of irreparable damage to the system. Performing regular preventative care will also keep your system from breaking down completely and needing emergency care, since that usually only happens when it is ignored for years. 
Getting a professional look at your equipment may cost money, but it will save your more money in the long term, as regular maintenance is much less expensive than emergency repairs and replacements.

The Short Story about PPR Pipes Fittings

The main function of PPR pipes fittings is that they are required to connect different lengths of pipes together to facilitate a smooth flow of the liquid content flowing within. Pipe connections are often used to maneuver the direction of the flow or regulate the flow within the pipelines. Pipe connections also make it possible to manipulate the lengths of pipe so that they suit the framework of the building or structure they will occupy. 

PPR pipes fittings are available in a large variety of designs, and they are all meant to serve different and specific purposes. The fittings are naturally available in different sizes, but they are offered in a number of different shapes as well, all to suit specific needs and requirements. Although all pipes made of all materials usually offer up a range of shapes and sizes, PPR pipes and pipe fittings remain as one of the most popular range of pipe fittings on the market. 

The reason PPR pipes fittings are preferred over other types of pipe fittings is because the common practice surrounding the use of pipe fittings is to utilize those that match the material of the pipes that they will be connecting. That remains as the primary criteria in choosing the material of the pipe fittings. The secondary criteria is that the function of the pipeline - whether the pipeline will be transporting clean water, waste, gas, or another product - is taken into consideration along with the function and properties of the pipe material. 

There are quite a number of factors that determine which shape and size of pipe fitting will be utilized. For instance, when it comes to size there is only one primary consideration. The internal diameter of the pipe fittings must be exactly the same as the internal diameter of the pipe so as to not cause disruptions and lags in the flow of material. This is also so that the buildup of materials can be adequately prevented. 

Whether you are looking for HVAC manufacturers in UAE or PPR pipe fittings, always contact them when you have any doubt about how they should be connected with the larger systems.

HVAC Equipment Basics - How to Select the Right Ductwork for Your House

If you are the lucky builder of your own house, then you are probably looking at a lot of different options for acquiring lifting services, building the MEP systems, and HVAC system of your home as well. In this blog post we will be looking at the HVAC equipment in general, and the selection of the right kind of ductwork for your needs in particular. 

In all likelihood you have a basic understanding of what your home needs in terms of HVAC equipment in order to be fully functional, but you also need experts to make sure the job is perfectly done. When it comes to sizing the ductwork required in your home, a specialist will have to look at a large variety and number of factors in other to gain the best estimate of what your needs will be in your home.

Contractors use certain guides when they are trying to size the ductwork in a residential home, because it is essential that they get it right the first time. It is important to size your HVAC ductwork for air conditioning purposes rather than heating purposes, since cooling the indoors requires more CFMs than heating it up. Of course, this is in cases where you want your HVAC equipment to provide both heating and cooling functions while sharing the same ductwork.

As mentioned before, there are a large number of factors that are taken into consideration for this estimation:
1. Colour of the roof
2. The amount of shade enjoyed by the house
3. R values of the selected insulation materials
4. Type and quality of materials used during construction
5. Average temperature of the location in which your home is being built
6. Size of the home
7. Number of people expected to occupy the home 
8. Area occupied by openings, aka windows and doors
9. The construction materials and insulation materials used for these windows and doors
10. Size of the kitchen

The more variables your estimator looks at, the more accurate the result will be. This will ensure that you are provided with the utmost in comfort and efficiency in your new home.

High Density Polyethylene Pipe Lining for Pipe Manufacturers in UAE

High Density Polyethylene, or HDPE, pipe lining is growing extremely popular among pipe manufacturers in UAE and many other parts of the world that experience high temperatures along with high humidity levels, which make it perfectly suitable for use in the Middle East and GCC as well. This is because the combination of these two climatic conditions can cause a large degree of damage to pipelines of a lesser quality, which was becoming a potential problem for pipe manufacturers in UAE.

With global warming on the rise, the combination of high temperatures and high humidity levels are increasing in frequency all over the world, thereby making pipe corrosion a problem in places it never used to be a problem before. This is where HDPE pipe lining comes in. As it is naturally resistant to weather related corrosion it can field off the worst that these weather conditions can bring.

This also ensures that pipe systems with HDPE pipe linings will last much longer and enjoy extended durability, thereby assuring homeowners and businesses alike that there will be less need for them to hire MEP contracting companies in UAE for problems with their pipelines, at least. This durability comes from a part of their manufacturing process, known as  the . This is something that many other types of pipes and pipelines are not capable of. The process of fusion takes place in a closed indoors space to prevent it from being affected by uncontrollable weather conditions.

These are not the only benefits of HDPE. The pipe lining is also elastic and agile, corrosion resistant as well as rust resistant. It is soon becoming the go to choice for many in this region, and with good cause.

Different Types of Grilles and Diffusers such as Perforated Ceiling Diffusers

There exists a subtle difference between grilles and diffusers such as perforated ceiling diffusers. Grilles are devices that have been manufactured so that they can supply air in a vertical position without suffering from any deflected air - which would lose its flow, power and velocity. Perforated ceiling diffusers, or swirl diffuser - virtually any type of diffuser has little vents all around it. These are also called blades and these blades have the function of distributing or diffusing the air throughout the indoor space. The air that comes through from ventilation diffusers is cut at an angle in order to let this happen. 

There are many different types of ventilation grilles and diffusers. Many of these are differentiated between in terms of materials used, function, and applicability to different situations. Some of the different types of materials that grilles and diffusers are made of are:
1. Aluminium
2. Steel
3. Stainless steel
4. Plastic

These can all be given various finishes, in any colour of choice if required. Other finishes can be of stainless steel or brushed aluminium, among a few others. Variable air volume system manufacturers also sometimes coat their products in similar finishes.

There are many types of grilles and diffusers in general that a client can choose from. The most commonly chosen among these include:

1. Egg Crate Grille : These are very simple grilles that are also very affordable. They are usually used when air needs to be extracted.
2. Bar Grille : Bars are included instead of blades in this type of grille.
3. Transfer Grille : Mostly used to provide ventilation but are also useful for preventing the spread of smoke and fire in such an event.
4. Louvre Bladed Diffuser : Very commonly seen in this region, these ceiling diffusers are capable of directing air in up to 4 directions.
5. Straight Bladed Diffuser : Similar to the previous diffusers, but are quite cheaper in comparison. They also sport adjustable blades.

Why do VAV box suppliers encourage owners to retrofit to DDC controls?

Variable air volume boxes as a part of HVAC systems in a building or facility have been in use for a long time. For more than thirty years variable air volume units have been providing comfort in the form of perfectly conditioned air to hundreds if not thousands of people at a time who are all located in the same open air space.

In today’s market you will find many different kinds of variable air volume boxes today. If you are on the lookout for HVAC items such as these, and others such as displacement units, all you have to do is look for the right VAV box suppliers. If you are able to find reliable and highly reputable VAV box suppliers then you will find that they stock variable air volume systems of all natures, that are suited to different purposes and load capacities. On the flip side, if you are working with a lot of variable air volume boxes then you will find a wider range of such systems, dating from years ago to brand new variable air volume system.

Some of these variable air volume boxes will be simple shutoff systems, while others will be more technologically advanced. The vast majority of them, however, will be in need of some sort of repair or replacement, especially in terms of the controls. If the controls on a variable air volume system are not reliable, then the entire system is not reliable. For this very reason many VAV box suppliers will recommend that, instead of constantly repairing and testing the system, building owners and contractors retrofit their existing VAV box with pressure independent DDC controls. This is particularly beneficial when dealing with older VAV boxes with electronic controls. Some of the many benefits of retrofitting with DDC are:
 
1. Improved Function: 
DDC controls enable users to see operational variables which allow for more accurate and controlled heating and cooling responses.

2. Improved Efficiency:
DDC controls also allow users to make more accurate adjustments in different modes.

3. Improved Overall Efficiency: 
Installing a whole system of DDC VAV boxes will provide feedback which can help optimize fan operation and reduce energy consumption.

VAV boxes have a lot to gain from being retrofitted with DDC controls, and the biggest bonus to this are the long term energy savings which amount to a significant sum.

Why a Builder’s Responsibility Exceeds that of Fire Door Manufacturers in UAE

It can be said that the role and responsibility of fire door manufacturers in UAE ends after they have supplied a well tested and high quality fire rated door for use in buildings, shopping centers, and other such facilities. The role of the building owner, when it comes to the maintenance, inspection, testing, and otherwise proper use of the fire rated doors and dampers - which form part of the HVAC system - is a never ending one for as long as they can be held responsible and liable for the safety of the occupants in the building or facility. 

This blog post aims to explore the responsibilities of a building owner in terms of procuring and installing a passive fire safety system: 

At the first level is the designer. The designer of the building plans needs to correctly identify and make the appropriate concessions for the placement of fire rated doors. These plans and particulars for passive fire safety protection need to be clearly marked. 

Once the designs for a passive fire safety system has been identified, they have to be submitted for approval along with the accompanying maintenance schedules and the like. This is a normal part of obtaining the building consent forms. 

Once the plans have been approved and the fire door obtained, the builder needs to follow the instructions provided by the fire rated door manufacturers in UAE to the fullest extent, making sure that the entire passive fire safety system is installed flawlessly. 

The builder then needs to get the installation of the fire protection system approved and acknowledged. Once this is done, the builder then needs to ensure that the maintenance and inspection schedules of the entire system are carried out when needed. Any change to the passive fire safety system must first be approved by the building authorities. 

In this way, we can see how far the building owner’s responsibility extends towards the design, installation, maintenance, and use of the fire safety system, and much of the responsibility lies on their shoulders rather than that of the manufacturer’s
