Design and Characteristics
A burner generates a long laminar flame inside the radiant tube, heating it up to 580°C. An exhaust system discharges combustion gases, while reflectors guide infrared rays to the occupancy level, minimizing heat loss and maximizing efficiency.

Tube Heater Technology
Radiant tube heaters are decentralized, gas-fired infrared heating devices that generate heat precisely where needed. They feature a Whisper-Jet burner for eco-friendly combustion and can use natural gas, LPG, or bio gas.

Efficiency and Energy Saving
Schwank tube heaters use calorised radiant tubes with an emission degree of 95% and insulated reflectors to enhance efficiency. The radiation factor can reach up to 77.5%, significantly reducing energy costs compared to standard products.

Product Variety
Schwank offers four categories of radiant tube heaters, from basic to high-end, each tailored to specific applications. They provide solutions for various fields, including industrial facilities and sports venues.

Exhaust and Air Supply Systems
Two main systems are available: single exhaust gas systems for individual heaters and collective systems for multiple heaters, with options for external air supply.

Project Design and Consulting
Uniform heat distribution is crucial for effective heating. Schwank provides expert support for planning tailored heating solutions.

Key Terms
Convection heat is minimized through insulation, enhancing radiation heat. Thermal efficiency measures the ratio of input to output power, with Schwank heaters achieving up to 93% efficiency.

Company Overview
Schwank, a German manufacturer, is a leader in gas-fired infrared heaters, known for high-quality, cost-efficient heating systems with over 150,000 satisfied customers worldwide.
