Water-cooled propane
chillers for the production of chilled water. The units are
equipped with semi-hermetic reciprocating compressors. Inverter compressors on
models 521-1001. Suitable for indoor and outdoor installation. Refrigerant
R290 (GWP 3) (propane) These units are specially designed for cooling medium to
large projects. Tandem technology offers multiple capacity stages and
increases efficiency at part load. This also improves performance. Leak
detector and ATEX certified fan in compartment with cooling circuit included as
standard. If installad indoor in a technical room, this room should be well ventilated area.
Mandatory commissioning by CAIROX.
