RADIK KLASIK - R - Steel panel radiators for renovation jobs
Description
The RADIK KLASIK – R model is a steel panel radiator in KLASIK design, modified for swift replacement of cast-iron sectional radiators with a connecting pitch of 500 mm.
The height H = 554 mm guarantees its problem-free fitting in place of the old radiator. It allows for left or right side connection to the heating system distribution mains and is designed for heating systems with forced or gravity circulation. Two upper and lower fixing lugs are welded onto the back, radiators 1800 mm in length or longer have six welded fixing lugs.
The wide range of types of RADIK KLASIK - R allows you to always choose the most suitable and appropriate length.
All radiators are supplied with:
- an air vent
- a blanking plug
- upper grille
- side covers
