Tender Specification
WQL / WQH / WQRC 524-1604
Victaulic connections.
Maximum working pressure is 10 [bar] water side and 45 [bar] refrigerant side
6 Condenser
Outdoor heat exchangers are brazed stainless steel plate type. They are
insulated with a 10 [bar] 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
All the units are equipped with two independent and separate refrigerant
circuits.
Each refrigerant circuit is equipped with two hermetic scroll compressors, sight
glass, filter-drier and mechanical expansion valve (electronic expansion valve is
available as an option, std fitted staring from 1104 size).
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.
