calorSchwank & infraSchwank

Schwank’s gas-fired infrared radiant tube heaters offer low intensity heat and very high degrees of energy efficiency. The generation of heat at low intensity makes Schwank radiant tube heating systems ideal for installation in low ceiling buildings. However, their excellent performance and the flexibility they can offer for system design and installation mean that these space saving ceiling-mounted heaters, which incorporate Schwank’s pioneering “Whisper-Jet” technology, can provide perfect comfort heat levels in a wide variety of workplace interior environments.

Similarly to Schwank’s plaque (luminous) heating systems, our radiant tube heaters can be configured into separate heating zones, thus ensuring efficient use of energy and reduced operating costs. Additionally, positive pressure fans offered with Schwank infrared burner systems allow our gas fired radiant tube heaters to create a very long laminar flame reaching far into the heater tube, leading to uniform heat transfer and increased energy efficiency.

calorSchwank is the premium Schwank tube heater model, with exceptional high heat resistant insulation as used in aerospace engineering, achieving a 4-fold improvement in the operation of our radiant tube heating systems over thicker conventional insulating materials.

Key features include:

• Radiant factor of up to 70.2%, leading to excellent efficiency and performance (independently tested according to DIN EN 416-2)
• Optional 2-stage or fully modulating control
• Ceramic insulation, minimising the convection heat share
• Long laminar flame
• Whisper-Jet pressure burner system
• Exceptionally quiet operation
• Quick and easy installation
• Highest German manufacturing quality
• Available as L- or U-version

infraSchwank is a reliable energy efficient infrared radiant tube heater offering a high level of radiant efficiency, with a radiant factor of 59.3% (independently tested according to DIN EN 416-2)

Similar to the calorSchwank, other key features include:

• Optional 2-stage or fully modulating control
• Ceramic insulation, minimising the convection heat share
• Long laminar flame
• Whisper-Jet pressure burner system
• Exceptionally quiet operation
• Quick and easy installation
• Highest German manufacturing quality
• Available as L- or U-version

Schwank gas-fired infrared tube heater systems can also be linked to our tetraSchwank heat recovery system, which has been found to achieve increases in heating output of up to 110% at low cost. Used in conjunction with the SchwankControl intelligent heating control, the system can exploit flue gas heat without using any intermediate heat storage capacity or medium.
