KORATHERM HORIZONTAL - M - Flat Panel Radiator with Middle Connection
Description
KORATHERM flat panel radiators are designed for double-pipe heating systems with forced circulation of the heat-carrying agent. The new types 23, 44 and 46 extend the product range of KORATHERM HORIZONTAL and KORATHERM HORIZONTAL – M models and thus allow for their use in more areas. All of these radiators are supplied with an upper covering grille and can only be fixed to the floor with the aid of special stand brackets.
Closed steel profiles are used for the heating elements with a rectangular cross-section of 70 x 11 mm, dividing and collector profiles have a crosssection in the shape of the letter “D” with dimensions of 40 x 30 mm. Heating profiles are aligned horizontally. The types are supplemented with an additional convector fin with a depth of 45 mm.
Connection of the KORATHERM HORIZONTAL - M model to the heating system is bottom middle with a connecting pitch of 50 mm. Types K23HM, K44HM and K46HM are manufactured up to a maximum length of 2000 mm.

Pressure Loss
The pressure loss of the radiator for the respective working conditions can be calculated by means of the value of the flow coefficient AT or the resistance coefficient ξT (see please the Technical Parameters).
| Type | Resistance coefficient ξT [-] |
Flow coefficient AT [m²] |
|---|---|---|
| K23HM | 105,7 | 2,76 × 10-5 |
| K44HM, K46HM | 46,3 | 4,18 × 10-5 |
