The Compact Softline low-temperature radiator is made of fine cold-rolled steel sheet 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 sheet is welded to the internal 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 finish coat in Stelrad white 9016. Each radiator is packed in cardboard with sturdy corner protectors and protective film. All units have mounting brackets on the back. Quality is certified to EN ISO 9001. Heat output is verified to EN 442. The design complies with the BAGUV safety guidelines.

Frequently Asked Questions

• What is the output of this particular radiator (600 x 1600 mm, type 33K)? This size and type version has a declared heat output of 3822 W (to EN 442, at standard temperature difference) - when choosing the right radiator size, base your choice on the calculated heat loss of the given room.
• What does the type designation 33K 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 sheets in its make-up; a higher number means more layers and therefore higher output at the same external dimensions. A radiator without the letter "V" in the type has a side connection - the classic placement of the 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 - ordinary domestic heating systems operate well below these values.
• What warranty does the radiator have? The manufacturer provides a 10-year warranty on tightness and heat output from the date of manufacture, provided professional installation, proper maintenance and operation are observed - 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 venting and balancing of the circuit.
