The Refrigeration circuit
Same compressor arrangement as on air cooled version.
Refrigerant R410a
Scroll compressors mounted single or tandem
Thermostatic Expansion valves
Stainless Steel 316 heat exchanger
4 Way valve for reversibility
Filter drier
High and Low pressure safety switches
Fully assembled and leak tested

6. Water Source Heat Pump Rooftop Range
The Hydraulic Circuit
As standard the water cooled range will be equipped
with the following features:
Low Pressure Drop (>50 kPa)
Stainless Steel Plate Heat Exchanger
Victaulic Connections & Couplings
Air vent on the highest point
Water filter
Electronic water flow switch
Pressure taps inlet and outlet
Fully insulated hydraulic parts when
located inside the unit
Option:
Low water loop temperature option
through flow control to maintain
Refrigerant High Pressure

7. Water Source Heat Pump Rooftop Range
Electronic flow switch
More Accurate
No risk of offset in time
Very Accurate flow measurement
More Reliability
No moving part
No Maintenance
No risk of blockage
Can work with any kind of fluid (glycol)
One single reference for the whole range
Easy to install
Stainless steel construction
FLOW
Heat is dissipated by the fluid
NO FLOW
Heat is not dissipated by the fluid

8. Water Source Heat Pump Rooftop Range
Air Treatment Section
Identical to the air cooled version,
The performance tables for ventilation / pressure drop remain unchanged
 Most of the air treatment features and options are compatible with this new range (Filters, Economiser, CO2 sensors heat recovery modules…)
