The WRU and WRL series are eminently suitable for use in combination with indirect-fired air heating.
A relatively small air-heating capacity can keep the room at a certain minimum temperature while the workplaces themselves can be pleasantly boosted by a radiant tube.
The radiant tube can be switched on as and when required, and the comfortable heat is felt almost immediately.

In situations where an old, poorly insulated factory bay has to be heated, the heating of the entire bay with radiant tubes also provides an excellent solution.
The effect of radiant heat is felt immediately, and it ensures a long period of retained heat so the radiant tubes can be switched off well before the end of the working day. 

Therefore, the WRU and WRL are very energie-efficient. Winterwarm Radiant tubes are also ideally suitable for buildings with high air change rates, e.g. in buildings with excessive ventilation and totally (or partly) open buildings.

There are 8 types of  WRU and WRL:  10, 12, 14, 22, 28, 33, 42, 50.

Upon request, Winterwarm can also supply overhead double linear tubes, also 8 types in the range from 20 to 100 kW.
