Standard units have pilots and are gravity vented. Energy efficient units feature electronic ignition and power venting. Radiant Heaters or Infrared Heaters, are typically used in warehouses and garages, and in drafty locations where doors are opened frequently. Infrared systems heat the objects, the floor and people beneath heating units. Absorbers use water as the refrigerant, completely eliminating the need for CFCs, which are known to damage the ozone layer of our atmosphere.
Absorption chillers have few moving parts, so operation is quiet and vibration-free.
Natural gas engine-driven chillers have the ability to vary the speed of the engine to match the load, resulting in high part load efficiency. Heat recovered from the engine can be used for heating domestic water or for other thermal applications. Desiccant Dehumidification Equipment . Desiccants reduce the ambient moisture in the air, making it more comfortable and easier to cool. They also have the ability to reduce the amount of airborne bacteria and fungus.
