Isotherm, Inc.

Isotherm Ultra Low Charge “SX” Evaporator was installed at a rink facility in British Columbia in 2019 to replace a conventional flooded evaporator.

After installation, it was confirmed that the new “SX” Chiller required only 50 lbs. of ammonia, while the 15-year-old flooded chiller that was removed held approximately 1500 lbs. of ammonia.  The “SX” chiller is a critically charged DX that does not require a receiver.  However, if the facility still requires one, then the size could be drastically smaller.  At the BC facility the drainpipe header from the condenser serves as a receiver.  

Isotherm’s push for innovative heat exchanger technologies is the big differentiator!
