Advanced Ammonia Technology for Low-Temperature Refrigeration Applications
Colmac Coil, Colville, Wash., introduced new Advanced Direct Expansion (DX) ammonia technology, which uses 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 site.
Additional benefits include 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.
