KW-Line – Water Cooled Condensing UnitsJuly 21, 2016
KV – Large Outdoor Air Cooled Condensing UnitsJuly 21, 2016
This unit features single or dual compressor(s) and a vertical discharge air-cooled condenser that is suitable for large walk-in coolers and freezers, blast freezers, warehouse applications and spaces where roof mounted condensers are most practical. Using high efficiency compressors and utilizing the THERMOSPAN™ condenser core design, the unit meets all application needs from 6 to 40 HP (high/medium temperature) and 7.5 to 44 HP (low temperature).
Our KM-line of condensing units meet or exceed the new “AWEF” requirements for condensing units. Use this guide which collects all of the AWEF numbers for compliant equipment: https://docs.k-rp.com/awef/kr_awef_quick_reference.pdf
