<p>The convective electric heater (convector heater) contains bod y 1 with holes (grid) 2 in the lower part and louvers 3 in the upper part for moving the air flow and electric heating element 4 located in body 1 with the possibility of interacting with air flow and provided with removable cassette 5 with at least one air filter located above the mentioned holes 2 in the lower part of body 1. Cassette 5 is of flat form. Cassette 5 contains sequentially installed electrostatic filter 6 of primary refining, and additional filter 7 of fine cleaning from the group as follows: high-efficiency particulate air filter, carbon filter, bio filter, vitamin filter, nano-silver filter, plasma filter, aromatic filter, catechin filter. Body 1 may contain fan. Electric heating element 4 is executed as cast-in- place or STICH (the heating element STICH is a dielectric plate stitched with heat-proof nickel-chromium conductor in a form of a thin narrow plate) or tubular electric heater with aluminum finning (no picture). The electric heater has connector cord (no picture) for connection to electric power supply network. The convective electric heater is preferably manufactured with capacity value as follows: 0.5; 0.75, 1.25; 1.5; 1.75; 2, 2.25; 2.5; 2.75; 3, 3.25 ? 3.5 kilowatt. At that, the electric heating element is protected from dust, air in the premise is purified, the coefficient of efficiency is preserved during the whole operation term.</p> |
