Carrier EF05BD332 Economizer Electronic Expansion Valve

The Carrier EF05BD332 Economizer EXV is a vital part of innovative commercial and industrial HVAC systems with R410A refrigerant. They can modulate refrigerant flow in the economizer circuit with high precision, a factor that makes the system efficient. Economizer circuits make use of outside air temperature to partly cool the refrigerant lightening the load on the main compressor and therefore minimizing energy use. This Carrier EXV operates with electronic control of a valve opening about the system conditions. There is a bimetallic component of the valve that moves in response to temperature variations and communicates with the electronic control unit.
