Applications for Condenserless Modular Chillers

If you do not have access to building supply water (cooling tower water), and dry fluid coolers are not an option, we offer high efficiency modular remote air cooled condenser chillers to be used with our high efficiency air cooled condensers. These condensers can be located on the roof or ground and can be designed to operate in ambients up to 105° F and down to –35° F during the winter months.

All our remote condenser air cooled chillers feature either Copeland “SCROLL” compressors with dual refrigeration circuits or single Bitzer Rotary  “SCREW” compressor with single refrigeration circuit, stainless steel copper braze plate evaporators, stainless steel copper braze plate condensers, our exclusive intelligent chiller control system, and a NEMA 4/12 powder coated control panel.
