Safety features include low ambient head pressure control and high short circuit current rating. In this regard, the chillers are built on a heavy-gauge galvanized steel frame and come with a range of security grilles and hail guard options. In addition to the importance of fire-safe materials for all equipment used underground, reliability is also a key issue. Carrier’s technology specialists were very innovative, and we worked closely with them to develop a custom-made chiller that met all of the requirements, and provides efficient and reliable cooling with proven Carrier technology.”Ĭarrier’s AquaSnap 30RB chiller is based on highly-reliable rotary scroll compressors running on refrigerant R-410A, a quiet-running AeroAcoustic fan system, and high-efficiency microchannel condenser coil technology. Carrier introduced the all-new AquaSnap® 30RC air-cooled scroll chiller featuring Greenspeed® intelligence and R-32 refrigerant, which complies with Jan.
