The Compact Softline low-temperature radiator is made of fine cold-rolled sheet steel to EN442-1 quality, with side panels and a top grille, forming a compact unit with a vertical water channel spacing of 33.3 mm. The convector fin is welded to the inner channels. Before painting, all radiators go through a multi-stage cleaning process, including iron-phosphate phosphating and a demineralised rinse. A primer coat is then applied, followed by a powder coat in Stelrad white 9016. Each radiator is packed in cardboard with sturdy corner protectors and in protective film. All units have brackets on the rear side. Quality is certified to EN ISO 9001. Thermal output is verified to EN 442. The design complies with the BAGUV safety directives.

Frequently asked questions

• What output does this specific radiator (600 x 400 mm, type 22K) have? This size and type has a declared thermal output of 693 W (according to EN 442, at the standard temperature drop) – when choosing the correct radiator size, base your choice on the calculated heat loss of the room in question.
• What does the type designation 22K mean? The number before "K" (e.g. 11, 20, 21, 22, 33) indicates the radiator's construction type – the number of radiator panels/plates and convector fins it contains; a higher number means more layers and therefore a higher output for the same external dimensions. A radiator without the letter "V" in its type has a side connection – the classic placement of connections on the sides of the radiator, suitable for standard side pipe routing.
• What is the maximum operating pressure and temperature? The radiator is designed for an operating pressure of up to 1.0 MPa and a heating water temperature of up to 110 °C, with a test pressure of 1.3 MPa – typical domestic heating systems operate well below these values.
• What is the warranty on the radiator? The manufacturer provides a 10-year warranty on tightness and thermal output from the date of manufacture, provided the radiator is professionally installed, correctly maintained and operated – the warranty does not cover mechanical damage caused during transport, handling or improper installation.
• Must installation be carried out by a professional? Yes, connecting the radiator to the heating system (single-pipe or two-pipe, with forced circulation) should be carried out by a heating engineer/installer, who will also ensure correct bleeding and balancing of the circuit.
