Tender Specification
WQL / WQH / WQRC 20-190
6 Condenser
Outdoor heat exchangers are brazed stainless steel plate type. In case of WQH
version they are insulated with a 10 [mm] thick closed cell polyethylene foam
material and provided with Victaulic connections.
Maximum working pressure is 10 [bar] water side and 45 [bar] refrigerant side
7 Refrigerant circuit
Refrigerant circuit is equipped with one or two hermetic scroll compressors
(depending on the frame), sight glass, filter-drier and mechanical expansion
valve (electronic expansion valve is available as an option, std fitted on 170
and 190 sizes).
Heat pump units (WQH) refrigerant circuit is also provided with 4-way reversing
valve and check valves system in order to always run liquid line in the same
direction (both in cooling and in heating mode).
Remote condenser units (WQRC) refrigerant circuit is supplied without
condenser and it is provided with liquid receiver, stop valves both on discharge
and liquid lines, solenoid valve on liquid line.
8 Control panel
A new optimized control is supplied on all the units with a simple user interface
