ADX™ Advanced Direct Expansion

ADX® LOW CHARGE AMMONIA

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. Because of the reduced ammonia charge on site and in the occupied spaces, regulatory burdens can be reduced, and work spaces made safer. ADX® Low Charge Ammonia - inherently safer technology.

This proven technology is being successfully used in multiple locations around the world.
