Electric air-heaters are designated for equipping the air-heating units of УВНЭ series, applied for heating and ventilation of industrial, agricultural, public and cultural premises, as well as other units instead of electric calorifers of СФО series; they are also applied as the independent products designated for air-heating of premises.

Conditions for operation – cold-temperate climate of the 4thcategory of location as per ГОСТ15150-69. Environment should be non-explosive and should contain no current-conducting dust.

Electric air-heaters are equipped with the heaters (ТЭНø 13 mm) made of carbon steel of standard quality with aluminium rolled ribbing. Materials applied for heating elements do not emit harmful substances while operating. Air-heater housing is made of sheet steel.

Air-heater is equipped with temperature relay ТВ-130 (or similar one), which switches the air-heater off when temperature of ТЭНribbing exceeds 130 ° С.

Air-heaters of option “01” are equipped with heaters (ТЭН) having the power of 2,5 KW; option “02” – with heaters having the power of 1,6 KW.
