Efficient heating and cooling with our compact heat pumps

FrioNordica’s heat pumps use ammonia as their refri­gerant and are delivered in standard sizes from 350 to 2 500kW. The system has a very high perfor­mance in relation of power consumption, saves space and requires little refri­gerant charge.

Features and benefits

• Ammonia is the most environment-friendly refri­gerant available, with excellent technical properties for low-tempe­rature heat pump operation.
• J&E Hall rotary compressor of single screw design. Balanced compression cancels out radial forces on the main bearings. Overhaul intervals of 100 000 hours give very low mainte­nance costs.
• Conti­nuously variable capacity control, 10–100%.
• Variable frequency drive for compressor and pumps.
• Seawater-cooled oil cooler for increased efficiency.
• Titanium tubes and tube sheets in all heat exchangers. Tube joints are expanded and welded. Water heads are plastic.
• Highly effective spray chiller with very low ammonia charge and low freeze-up risk.
• 10-year corrosion guarantee for parts in contact with seawater.
• FrioLogica controller offering automatic operation and monitoring of parameters. Supported and updated over the internet.
• Heat exchangers and units are produced at our own factory in Norway.
• Including heat exchangers for effluent energy recovery, the system can give up to 30kWh of combined heating power for each kWh of elect­rical energy consumed.
