High Energy Efciency Rating

The McQuay MWH series of water source heat pumps have energy efciency ratings as high as 16 and provide

better energy consumption than that of most conventional air-cooled systems.

Packaged Unit. Compact. Low Height Prole

The McQuay MWH series of horizontal water source heat pumps is a packaged unit consisting of compressor

(2 off in MWH025 and above), coil, tube in tube heat exchanger, expansion device and forward curved

centrifugal blower. All units in this series have a very low prole, from 250mm for the MWH011B/BR, which has

a horizontal compressor, to the largest unit in the range at 500mm.

No Separate Outdoor Unit

The packaged design concept eliminates the need for a separate outdoor unit. Also, the tube in tube heat

exchangers in the MWH range do not need a fan to transfer heat load, resulting in a much quieter environment

for building occupants.

Double Isolation Panel, Less Vibration

Unlike other conventional designs, the MWH series of water source heat pumps apply a double insulation

concept, where the compressor is mounted on an extra upper panel. Vibration generated by the compressor

is absorbed twice to the rubber grommets, before it reaches the unit casing.

Extremely Quiet Design

No outdoor fan, double isolation panel for compressor, superior insulation and use of twin rotary compressors

in models above MWH025B/BR all add up to a quieter design. Particularly in night set back mode.

Application Flexibility

The McQuay MWH B/BR series has a wide range of operational temperatures. This means the entering water

temperatures can be adjusted from 13°C – 45°C for cooling and 10°C – 32°C for heating.

Safety Protection Devices

Several safety protection devices are integrated into the MWH B/BR range of heat pumps to monitor their

operation as well as provide necessary protection for all standard operational functions.

Partial Loading Capability

For MWH025B/BR to MWH070B/BR, which are having two compressors in their system, the capacity

loading of compressors are able to controlled at 50% or 100%.

Sequencing Control

For the MWH025B/BR to MWH070B/BR, the compressors are able to operate in sequencing mode. This

will allow both compressors to cut in and out according to their accumulative run times. This dramatically

improves the compressor life and reliability.
