On July 4, TASS reported that Gyplar, a resident company of the Novosibirsk Technopark, has successfully developed an air ventilation system capable of stable operation in the extreme cold climates of Siberia and the Arctic. The company's technical director Evgeny Fedorov revealed this breakthrough to reporters.

Traditional building ventilation systems suffer from significant heat loss, with about two-thirds of heat escaping through ventilation ducts. While heat exchangers can provide ventilation with heat recovery, they frequently fail due to icing in extreme cold environments ranging from –50°C to –100°C. To address this challenge, the engineering team developed a new design that optimizes the heat exchange mechanism to ensure reliable operation at low temperatures.

Fedorov explained that the device uses a plate-type heat exchanger consisting of a set of rotating disks connected along inner and outer edges, forming supply and exhaust air channels. The core innovation is that the heat-exchange surfaces slowly rotate at approximately one revolution per hour, keeping the ice layer at a stable thickness without compromising heat-exchange efficiency. During operation, the iced sections move with the rotation into the warm air inlet zone, where they automatically defrost, and condensate is discharged through dedicated channels.

Anton Shmatov, Gyplar's Executive Director, stated that the device has entered batch production with a planned annual capacity of 200 units. The company is currently in talks with the Arctic and Antarctic Research Institute and plans to send samples to Russia's Vostok Station in Antarctica for field testing – where summer temperatures drop to –30°C and winter can reach –80°C. Fedorov added that, in addition to Russia's northern regions, there is demand for the equipment in similarly harsh climates such as Alaska and Canada.
