Air compressors are machines that compress air to higher than atmospheric pressures for delivery to pneumatic or robotic tools, industrial equipment, or direct-use applications

Refrigeration compressors and air conditioning compressors provide air conditioning, heat pumping, and refrigeration for large-scale facilities and equipment. Refrigeration compressors are sometimes called refrigerant compressors

Enclosure air conditioners remove the heat generated by electronic devices from the inside of cabinets or enclosures. They typically use refrigerants and include thermostatic controls to maintain programmed environmental conditions

DC to AC inverters are used for converting direct current (DC) into alternating current (AC). They are also known as DC to AC converters

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 and commercial 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

Thermoelectric coolers are solid-state heat pumps used in applications where temperature stabilization, temperature cycling, or cooling below ambient levels are required.

HVAC controllers are used to monitor and control heating, ventilation and air conditioning (HVAC) systems in buildings. They monitor indoor environmental factors such as temperature and humidity, and control heating and cooling to maintain desired levels

Electrical power generators transform mechanical energy into electrical energy, typically for backup or emergency power. Generators can produce either AC or DC power and are typically powered by a fuel engine
