Schwank Gas Radiant Overhead Heaters

Gas Radiant Heating Overview

schwank gas tube heaters

Schwank is the world leader in gas radiant heating. After having invented infrared gas heating over 75 years ago, Schwank has become internationally recognised for their state-of-the-art, high performing overhead heating systems.

With over 160 000 satisfied customers and more than two million units sold worldwide , Schwank systems are produced with the highest European quality available. Developed in Germany, Schwank provides the best energy saving products whilst minimising CO2 emmissions.

What is infrared heating?

Infrared waves and heat rays warm people and objects like the sun warms you on a cold winter day. The heat is carried by electromagnetic waves from the radiant gas heaters to people and surfaces but is not seen or felt until it has made contact. In addition to warming people, the surrounding surfaces are also warmed.

  • Automatically determines the optimum pre-heating time
  • Remote control/remote service as an option
  • Integration to Building Management Systems (i.e intranet or fire alarm system)
  • Simple, economic, efficient and ecology-minded
  • Easy ThermoControl Plus M menu navigation
  • Quick access to all important setting parameters
  • Stores all heating characteristics and logs
  • Less wear & tear by reducing on/off cycles by 43%

Radiant Heating Technology

The unique and innovative “Whisper-Jet” burner creates a long laminar flame that reaches the length of the protracted tube. The flame runs through the tube in an axial direction, thus distributing the heat in a more uniform way. This guarantees a continuous heat transfer from the flame over the entire length of the tube.

The pressure fan allows for the flow characteristic of the gas-air-mixture to achieve a better and more uniform heat distribution. In addition to this, components, such as the fan and its ball bearings are not exposed to the hot flue gas. This contributes to a longer life of these parts.

By optimising the flow characteristic and using the pressure fan, Whisper-Jet is an exceptionally quiet burner with approx. 46dB[A] at 3m distance – only a quiet whisper can be heard.
The patented Schwank ceramic burner tile also ensures clean combustion of gas-air-mixture.

The design follows decades of research into gas-fired infrared radiant heating and technical advancement making the Schwank burner technology second to none.

Application

Radiant heating technology can satisfy a variety of heating requirements and applied for many purposes including:

  • Commercial & Industrial
  • Indoor & Outdoor Environements
  • Industrial factories
  • Warehousing and Logistics buildings
  • Vehicle service garages and Wash Bays
  • Airplane Hangers
  • Welding and fabricating shops
  • Sports facilities
  • Show rooms

Radiant Efficiency Factor

The ‘radiant efficiency’ or ‘radiant factor’ of a gas radiant overhead heater is determined by the percentage of consumed energy transformed into useful, radiant energy from the combustion process.

A higher radiant factor can mean that:

  1. Not as many heaters are needed, which results in savings of both capital and running costs.
  2. Heaters do not need to run for as long to be able to maintain a comfortable temperature.

Schwank Radiant Overhead Heater Models

Schwank’s range includes two models for two different radiant efficiency factors: the calorSchwank and the infraSchwank.

calorSchwank

The efficient calorSchwank features a very radiant factor of up to 72.7%. This premium model tube heater achieves this level of efficiency thanks to its innovative burner technology and high quality ceramic reflector insulation. The combination for advanced materials enhances the radiant characteristics of the tubes and reflection properties of the reflector.

These heaters ensure lower energy cost due to their insulated interior. The insulation minimises the amount of convection heat and increases the radiant factor, thus improving heat transfer.

Features

  • Radiant factor of up to 70.2%*
  • Long laminar flame
  • Pressure burner system
  • Whisper-Jet for stand-alone systems
  • Extremely quiet
  • Quality European parts, Made in Germany
  • Quick and easy installation
  • Available as L or U version
  • Ceramic insulation/minimisation of the convection heat share
  • Works with either Natural Gas or LPG (liquified petroleum gas aka propane gas)

infraSchwank

The infraSchwank’s unique patented ceramic burner technology sets the standard for tube heaters and energy efficiency. The specialised design contributes to noticeable energy savings without compromising the quality or amount of heat delivered.

Features

  • Radiant factor of up to 59.3%*
  • Long laminar flame
  • Presusre burner system
  • Whisper-Jet for stand-aline systems
  • Extremely quiet
  • Quality European parts, Made in Germany
  • Quick and easy installation
  • Available as L or U version
  • Works with either Natural Gas or LPG (liquified petroleum gas aka propane gas)

Controllers

The Schwank controllers are the brains behind the energy efficiency and cost effectiveness of the Schwank tube heaters. They can fulfil various requirements and demands, taking operating comfort into consideration.

The SchwankControl Touch offers the possibility of recording and evaluating a large amount of information related to their status, their performance of their consumption. For its part, the ThermoControl Plus is an intelligent control system that allows the tube heaters to adapt to the particular application they have been installed in.

SchwankControl Touch

The SchwankControl Touch can record and evaluate a broad variety of information relating to the performance or the consumption of the heating system. The information is collected in real time and the date presented in a transparent & intuitive form.

The controller allows individual settings for several heating zones in a commercial building. The intuitive user interface can quickly be adjusted for holiday periods and shift times.

Product Info

ThermoControl Plus

ThermoControl Plus can reduce running costs by determining when the heating system should be set into operation with a self-learning function. This intelligent control system features a practice-oriented service modules and a self-explanatory menu navigation.

By simple key operation, all nominal and actual values can be displayed and edited in a matter of seconds. In addition to this, ThermoControl Plus allows for adding an external alarm contact to a Building Management System [BMS] or external fire alarm system.

ThermoControl Plus controls single-stage as well as fully modulating infrared heating systems.
