One-stream  air-heating  units  of  СТД-300  type  are  applied  for  air  heating  in  industrial and agricultural premises, as well as in heating and ventilating systems of buildings, under the conditions of moderate (У) climate of the 3rdcategory of location as per GOST 15150-69. Air should have maximum permissible  concentration  of  chemically  active  materials  as  per  GOST  12.1.005-88,  dust  content  not more than 0,5 mg/m3 and no adhesive substances and fibrous materials.

Air-heating  units  СТД – 300  are  designated for operation  with  such  a  heat-transfer  agent  as  hot (superheated) water (for СТД-300 based on calorifer of КСкtype) or dry saturated steam (for СТД-300Пbased on air-heater of  КПtype), having temperature not more than 190° Сand operating pressure not more than 1,2 MPa.

Heating units of СТД-300 type (water) are manufactured in right-hand option – if to look at the unit from the side of an axial fan calorifer delivery pipes are located from the right side of the unit, and for lefthand one delivery pipes are located from the left side.

Heating units manufactured by «Concern Medved» haveprotective mesh, which protects electric motor from strokes and deformations, as well as prevents the unit from ingress of foreign objects. Forthe purpose of convenience there is a box for unit connecting to mains.
