Three models are initially available. One offers natural convection with outputs from 209 to 436 W/m, and two provide fan-assisted convection with outputs from 383 to 1800 W/m.
The natural-convection K types have a 106 mm-high casing and 2-, 4- or 6-pipe heat-exchanger elements set in steel retainers. They are supplied with linear or roll-down grilles and lengths from 950 to 4840 mm.
Type KG has a radial fan at the end of the unit with an air-distribution duct running parallel to the convector heat-exchange elements. It can be operated as a constant- or 3-speed unit, and comes in lengths from 1550 to 4250 mm.
The KEL is similar to the KG, but has a tangential fan.
