About Air Handlers

Air handlers are a system-like device used in ventilating systems. Air handlers typically consist of a blower, heat exchange medium for heat or air conditioning, and housing. An air-conditioning system is a good example of an air handler. An air-handler unit is the main component of an air-conditioning system. An air-handler unit includes various dampers, an air filter, heating and cooling coils, and a fan. Dampers control the flow of outside air, return air, and mixed air. The air filter removes dust particles from the air, heating and cooling coils condition the air, and the fan delivers the conditioned air to various parts of the building. Air handling effectively circulates conditioned air throughout a space. When matched with a heat pump, air handling circulates both cool and hot air, depending on the season. There are several types of air handlers. Examples include an HVAC air handler, air filter handler, and hot water air handlers. HVAC stands for heating, ventilation and air conditioning. These three functions of HVAC Air Handler are closely interrelated and control the temperature and humidity of the air within a building. Air filter handlers remove dust from an air stream as the dust-laden air passes through them. Hot water air handlers consist of a hot water coil, the air handler, a condenser and/or furnace, and a water heater or boiler. Other air handlers are commonly available.

There are several ways in which air handlers function. Air handlers are used for both commercial and residential purposes. A commercial air handler is normally a very large system moving 2000 CFM to 10,000 CFM and higher. A commercial air handler may be mounted on a roof or in large mechanical rooms located in a building. A commercial air handler has an economizer or inlet damper that allows for a small amount of outside air or make-up air to be pulled in through the air handler. In an air handler residential system, heat pumps or air conditioners along with air handlers compile a quality heating and cooling system, which can be installed for non-commercial purposes. All air handlers are designed to move a certain amount of air (in both the heating and cooling modes) at an approximate pressure drop. For example, a 3-ton heating/cooling system may be designed to move up to 1200 CFM at a total system static pressure of 0.5" (w.g.) with a ½ Hp motor. Air handlers are designed and manufactured to meet most industry specifications.

Products & Services Related to Air Handlers

Diffusers and Grilles
Diffusers and grilles are used to control and direct airflow in heating, ventilation, and air conditioning (HVAC) systems.
Heat and Energy Recovery Systems
Heat and energy recovery systems recover useful energy in one of several forms for use in a related or unrelated process system. This energy can be recaptured from heat, flow, pressure, and/or gases.
HVAC Chillers
Heating, ventilation and air conditioning (HVAC) chillers are refrigeration systems that provide cooling for industrial and commercial applications. They use water, oils or other fluids as refrigerants.
HVAC Ductwork
HVAC ductwork includes pipe or closed conduits made of sheet metal, fiberglass board, or other suitable material for conducting air to and from an air handling unit.
Industrial Cooling Systems and Equipment
Industrial cooling systems and equipment includes air-to-air, liquid-to-air, and liquid-to-liquid heat exchangers; ducts and/or pipes; and other devices for removing heat from a system that contains a heat source.
Industrial Fans and Industrial Blowers
Industrial fans and blowers are designed to move air and/or powders in industrial and commercial settings. Typical applications include air circulation for personnel, exhaust or material handling.
