Air handlers are a system-like device used in ventilating systems. They typically consist of a blower, heat exchange medium for heat or air conditioning, and housing.
Dampers and louvers are used to control the flow of air in a process system or enclosed area. Dampers are usually motorized or manually-adjustable for flow control. Louvers are often fixed for a constant flow rate.
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 industrial cooling 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 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.
