What You Need to Know about the Pre-Insulated Ducts

The pre-insulated ducts offer great cost efficiency. They can retain greater heat and hence help you to save on your energy and electricity consumption costs. The ducts use the rigid kind of polyurethane foam and are laminated on either of their sides with an aluminum foil. Polyurethane is chemically and physiologically inert and is also un-soluble.

The foam pre-insulated ducts are a better alternative to the older sheet-metal ductworks.

Benefits of pre-insulated ducts
The ducts are light in weight. They can be very easily installed in any room or zone. Their installation is also quite cost effective and requires the least of time.

No air leakage
Pre-insulated ducts help prevent any kind of air leakages. They hence improve the efficiency of your HVAC or heating, ventilation and air conditioning system and provide you an efficient system that runs in an optimal manner, for decades to come, with least of maintenance.

No sweating
The insulation provided in the ducts is of greatest of density. The system is hence devoid of any kind of sweating.

Clean and hygienic
The modern pre-insulated ducts do not contain any kind of fibrous materials. Hence, any kind of dirt and filth cannot attach itself to the systems. They are quite improved with respect to their hygienic aspects as well. The ducts can also resist any kind of fungal growth and offer clean and hygienic air to all areas.

Cost saving
The efficient pre-insulated ducts help in saving of costs related to electricity. You can save up to 30% on your energy bills by integrating them into your HVAC system.

Great built features
The self-supporting pre-insulated ducts have great rigidity and integrity. They use high quality materials and do not suffer from corrosion and other adverse effects of an operational environment, for longer time periods.

No size limit
The ducts are now available in almost all kinds of sizes. They can hence be integrated with any kind of ducting system of an HVAC unit.

Pre-insulated ducts offer a number of advantages. Leading and renowned suppliers of perforated ceiling diffusers in Iran like Bin Dasmal can provide you with best pre-insulated ducts. They are a great innovation and can be used for hygienic and clean air supply.

How Variable Air Volume System Manufacturers can Help You Reduce Energy Consumption

During a time of global climate crisis, all home and business owners are concerned with the rising price of energy, both economic and environmental. The vast majority of home and business owners who have an HVAC system installed in their place of work and living try to find ways to curb the amount of energy that is consumed by the heating and cooling equipment. This energy utilization is hugely heightened by the presence of severe temperatures during the summer and winter seasons. However, it is possible to control this energy use, and that is through regulating the flow of air inside an HVAC system, which is where variable air volume system manufacturers comes in. 

VAV systems offer owners of HVAC systems several advantages. The simplest kind of system manufactured by variable air volume system manufacturers supplies evenly heated and cooled air, the air flow of which is variable according to the requirements of the thermostat controlling the temperature of the zone the VAV system is serving. This kind of precise temperature control is one of its greatest advantages that allows for highly effective heating and cooling while conserving energy at remarkable rates. Another important distinction to make in the case of VAV air flow is the resulting dehumidification. Since the air flow is often reduced in many circumstances, the air is exposed for much longer periods of time than is normal to the cooling coils inside the HVAC system. Water vapour from this air condenses onto the coils and as a result dehumidifies the air, which creates a larger sense of comfort to the inhabitants of the indoor space.

The biggest and often the most coveted advantage of variable air volume systems is the fan control it incorporates. This fan control has evolved to serve the purpose of effective operation with even lower energy consumption. The newer models of electric fans can even serve as electric dampers in no small part due to their variable speed drives.

Incorporating a variable air volume system into one’s HVAC equipment is a necessity that accomplishes several goals. In the case that there is insufficient space to routinely incorporate the VAV system into a facility’s ductwork, flexible duct manufacturers can be called upon to correct this situation.

What You Need to Know about a UL Classified Fire Damper

Not many people who are not implicitly familiar with the industry will know the details about fire dampers, in fact, the general consensus is that it is a helpful part of the framework of a building in the event of a fire emergency. Fire dampers play an essential role in helping to curb the spread of fire. A UL classified fire damper is used to maintain the fire ratings of other fire rated walls, floors, etc. when they are interrupted by ducts.

Fire dampers shut close in the event of a fire emergency to prevent the flame from spreading further, especially through ductwork and eventually the supply ceiling diffuser in Dubai. This is possible because of a fusible link installed in the ductwork, which is designed to melt at 73.8 degrees Celsius, thus causing the UL classified fire damper to close. There are certain situations where the fusible link is designed to withstand hotter environments and respond to a temperature of 100 degrees Celsius. This is because some environments create a hotter “normal” temperature that is not indicative of a fire. Being an Underwriters Laboratories or UL classified fire damper means that the damper has been certified to carry a fire resistance rating which is measured in hours. This rating usually goes from 1.5 to 3.0 hours.

There are two major types of fire dampers. These are Dynamic Fire Dampers, and Static Fire Dampers. Dynamic Fire Dampers are used in situations where the building’s HVAC system’s blower will keep working in the event of a fire, or the Fans On mode. Static Fire Dampers are meant to used in emergencies when the HVAC system’s blower will be in Fans Off mode. This distinction is important because Dynamic Fire Dampers are specially designed to be able to function correctly against a strong air flow.

This post outlining the purpose, function, and types of fire dampers reveals how important they are to the structural integrity of a building’s fire safety standards. Highly rated fire dampers are responsible for containing a fire to as small a size as possible, preventing quick spread and heavy losses in densely populated areas.
