Economizer
|
The function of the economizer is as its name implies, to economize or save on cooling costs. Obviously, it costs money to operate the compressor. If the compressor can be shut down and the system still provide adequate cooling, energy savings can be realized. Heat internal to the building such as people, lights, computers, copy machines, motors and other machines causes the temperature inside a structure to increase. Heat soaked up by the building structure may also continue to heat the building long after the temperature outside the building has dropped. There are times when the temperature outside a building is lower than the temperature inside. Products & Services

Gearboxes and gearheads, also called gear reducers or speed reducers, are power transmission devices that use a gear arrangement in an enclosed housing to transfer energy, increase torque and reduce speed from one device to another. Gearboxes may also be referred to as gear reducers or speed reducers.
