Each unit is fully factory-built and comes as an integrated and complete solution with a welded, robust, and painted frame. The Fenagy heat pumps are available as air-to-water (AW) and water-to-water (WW).
The pipes used on the suction side are Stainless steel AISI304 (80 bar) and on the pressure side Steel P235GH (130 bar). The compressors are from the Dorin CD400 and CD500 series and with inverters on minimum one MT compressor and one IT compressor. Additionally, oil separator, oil management, related valves, receiver, and other vessels are assembled as well. The welded internal heat exchangers are used to optimize the heat pump’s performance.
The regulation and service valves are made easily accessible and service friendly, and before delivery, pipes and vessels are insulated. The heat pump will be delivered with oil, but not with refrigerant.
The WW heat pump are assembled with plate heat exchangers and injection valves. The heat exchangers to district heating (excl. pump) are Alfa Laval AXP112.
Finally, all required safety equipment, sensors, and instruments are integrated in the delivered heat pump.
As well as being fully assembled, the heat pump will further be programmed, configured, and tested. Fenagy has developed their own control system with a graphical interface. It is an open communication interface with touch screen supporting MODBUS-TCP and PROFINET, among others. This will be tested before delivery.
Other options available
Air evaporators and base frame, equipment to defrost evaporators, enclosure for the heat pump, and CO2 alarm for machinery room are other available options.
