Heating Solutions, Tube Heaters

Gas-powered tube heaters operate decentrally, generating heat where it is needed. A tube heater emits infrared radiation through its long radiant tubes. Schwank tube heaters (also known as dark radiators) are characterised by innovative detail solutions and the highest "Made in Germany" quality standards. The materials used are consistently designed for longevity and efficient heaters.

These radiant heaters can operate effectively across a full range of industrial and commercial workplace environments and public spaces. Decentralised systems of gas-fired infrared tube heaters, in common with luminous (or plaque) radiant heaters, are highly flexible and energy efficient. Benefits include the capability of a system being configured into separate temperature zones, allowing heat to be directed appropriately to allocated locations.
