The UVRK 50 device for local ventilation of apartments, offices

The principle of operation of UVRK devices is simple and natural. Process reminds breath of the person in frosty weather through a scarf. At an exhalation we give to scarf fabric part of heat of the exhaled air and part of the exhaled moisture, and at a breath fresh air, passing through a scarf, takes away both the part is warm, and part of moisture, and returns them to a favourite organism. Effect double: and to a throat is warmer, and mucous nasopharynxes do not dry up. Almost everyone instinctively resorts to such method of "ventilation of lungs with recovery of heat in a motionless regenerator scarf".
The similar principle is realized in UVRK devices.
In a phase 1 fan of installation deletes air from the room. Air, passing through a heatcapacious air-permeable regenerator, heats it.
In a phase 2 the regenerator is heated-up and there is a fan reversal.
In phases 3 and 4 cold external air, passing through an installation regenerator, heats up almost to room temperature, cooling gradually a regenerator. Further processes repeat.
Use in the apartment of two installations in different rooms which were not less working in an antiphase is optimum. Further their quantity can be increased by the consumer (on number of rooms).

UVRK-50 is a device of the second generation which cornerstone the same principles of work are, as in UVRK-30, but it more productive and functionally equipped at the same dimensions.

The technology used in the UVRK-50 device does not apply for revolutionism.
Nevertheless, the UVRK-50 device is new to Russia, is very simple, reliable, effective and efficient at extremely low temperatures.

The UVRK-50 device provides to consumers
· Prevention of formation of a fungus and moist damages;
