These are direct expansion air-to-air heat pumps with static and refrigeration energy recovery through a regenerative circuit. HRR units are characterised by their ability to perform dehumidification through three different and complementary systems: refrigeration dehumidification (active), thermal exchange in the heat exchangers, and replacement with outdoor air. The combination of these three systems provides high drying capacity with minimal consumption.

Although these machines can dehumidify through free drying with outdoor air, their refrigeration and recirculation drying capacity is far superior to that of other competing units, ensuring drying in any geographical location and climate condition.

Additionally, and just as importantly, it should be noted that the arrangement of the HRR’s refrigeration circuit elements is designed to maximise the performance of the integrated heat pump, as the evaporator functions almost exclusively with latent heat. This means the net heating capacity provided by the unit is much higher than that of any conventional dehumidifier, allowing for significantly lower heating costs.

Borealis HRR dehumidifiers are equipped with a double air-to-air exchanger with Eurovent-certified efficiencies exceeding 90% in standard winter conditions. Protected against corrosion with a high-quality oven-baked epoxy coating, these exchangers are specially designed for use in pool environments and manufactured by one of the most prestigious companies in Europe.

Our HRR units are standardly prepared to incorporate high-efficiency filtration in each of the air circuits. As standard, they are equipped with R.I.T.E. filtration, which includes F8 filters in supply. Optionally, and without the need to add additional modules or change the machine’s mechanical elements, higher-efficiency filtration can be installed.

The HRR units come standard with iPro control, programmed by Borealis for this specific application. iPro is hardware manufactured by the Emerson Group with integrated proportional control, IP communication, and MODBUS. It includes a web server with a page where the machine’s operating parameters can be viewed and modified. It can be directly connected to the building’s router with only the connection cable required, allowing monitoring from any computer or mobile device (phone, tablet, etc.)

The software is designed and implemented by Borealis, allowing us full process control and enabling continuous improvements and updates.

The Borealis HRR dehumidifying heat pumps are machines designed around energy efficiency: achieving maximum performance with minimal energy consumption. They are also designed to be durable and to allow for easy and economical maintenance.
