For single source responsibility, many people prefer the convenience of using an integrated refrigeration system depending on the application. Venmar CES offers a variety of high performance options in both air cooled and water cooled varieties.

Air cooled systems always include a direct expansion evaporator coil in the supply airstream, coupled with an integrated air cooled microchannel condenser and compressor section. The use of a microchannel heat exchanger improves performance, reduces the amount of refrigerant required and decreases the total weight of the system. The compressors are scroll type and the fans are quiet, vertical discharge, direct drive fans with steel blades. The air cooled system, depending on the capacity required, is available in single or multiple circuit configurations with the option to include Variable Refrigerant Control (VRC)^® for reliable control and part-load performance from 10% to 100% modulation, and eliminates the need for hot gas bypass. Precision temperature and humidity control along with significant energy savings are the obvious benefits. Optional on/off or modulating hot gas reheat is also available.

Water source heat pump (WSHP) systems are suitable for both geothermal ground/vertical loop or boiler tower applications. WSHP systems come equipped with a direct expansion evaporator coil in the supply airstream coupled with coaxial, cupro-nickel, corrosion resistant, tube-in-tube heat exchangers in single or dual circuits—depending on capacity requirements and Variable Refrigerant Control on the lead compressor. For enhanced energy savings, a factory mounted, multi-row waterside economizer coil is also available to be piped in series with the condensers to provide free cooling and heating. Venmar CES also offers a number of integrated waterside pre-piped valve and control options to reduce installation time, start-up and single source responsibility for trouble-free operation.
