Air Terminals

Air Terminals

Air terminal units are small air handlers designed for local use and may only include an air filter, coil, and blower. These simple terminal units are called “blower coils” or “fan-coil units.” Makeup air units are larger air terminals that condition 100 % outside air (and no recirculated air). Air handlers designed for outdoor use, typically mounted on rooftops, are known as packaged units (PU) or rooftop units (RTU).

Manufacturers: Metalaire

Air-Handling Units


An air handling unit (AHU), conditions and circulates air as part of a heating, ventilating, and air-conditioning (HVAC) system. A typical air handler is a large metal box containing a blower, heating and/or cooling element, filter racks or chambers, sound attenuators, and dampers. Air handlers connect to ductwork that distributes the conditioned air throughout the building and returns it to the AHU. AHUs can alternately be set up to discharge (supply) and admit (return) air directly to and from the space served without ductwork.

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required. As a necessary byproduct, refrigeration creates waste heat that must be exhausted to ambient or, for greater efficiency, recovered for heating purposes.

Manufacturers: York

Cooling Tower

Cooling Tower

Cooling towers are heat removal devices used to transfer process waste heat into the atmosphere. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the cased of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near dry-bulb air temperature.

Exhaust Cleaning Systems



Waste air purification systems combine photo-oxidation and catalytic oxidation for removal of pollutants, odors and solvents. The waste air purification process is based on a technology that induces photo-oxidizing reactions to remove organic solvents and odorous substances using UVC light as the driving force in this process. A catalytic converter further increases the effectiveness of the oxidation reactions.
