Low Charge Advanced DX Ammonia (ADX) Case Studies
Colville, WA: Colmac Coil has pioneered the use of low charge direct expansion in low temperature industrial ammonia refrigeration applications. This new technology reduces the first cost of installation while significantly reducing the ammonia charge required on the site. It has been proven in recent installations that using ADX in industrial refrigeration systems produces additional benefits including: faster defrosting, effective operation at multiple temperature levels (convertible rooms), good response to changes in load, fast restart after power failure, and simplified maintenance and operation through elimination of recirculation pumps.
