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 tube heater 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.

The tube heater’s fan burner generates a long laminar flame heating the tubes up to 650°C, allowing the tubes to emit infrared heat through a special alloy.

Tube heaters are also referred to as ‘dark heaters’ because they do not glow brightly like luminous heaters. In fact, tube heaters do not emit any light at all.

The heat felt by these heaters always sits above the actual air temperature. The lower air temperature also reduces the differences between inside and outside temperature – thus cutting down on the heat transmission losses at the same time.

The calorSchwank is incredibly energy efficient consuming up to 20% less energy than that of the infraSchwank, featuring a very high 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.
A combination of other advanced materials also enhances the radiant characteristics of the tubes and reflection properties of the reflector.

These heaters also ensure lower energy costs because of their insulated interior which minimises the amount of convection heat and increases the radiant factor and improving the efficiency as heat that accumulates below the ceiling is considered a waste of energy.

The infraSchwank’s radiant efficiency factor goes up to 60.2%.The infraSchwank’s unique patented ceramic burner technology and specialised design of tubes and reflectors sets the standard in the realm of tube heaters and energy efficiency. Noticeable energy savings are easily achieved without compromising the quality or amount of heat felt.

On top of the radiant efficiency factor, you can also choose the way you control the output of you Schwank heaters. The infraSchwank and the calorSchwank come indeed with two different control options: 1-stage control or modulating control.

1-stage

The 1-stage control is the most basic way of controlling your Schwank heater: it is either ON or OFF.

Modulating

The modulating control gives you more power on the output of your Schwank heater, as you can modulate its output from 70% to 100% of its maximum output. The modulation control provides the possibility to adapt the performance of the heating system to the actual heat demand. Therefore, the energy cost can be reduced by up to an additional 14% and the thermal comfort is improved. The operating cycles [On/Off] is reduced by up to 35% which in turn increases the life expectancy of the appliances.

Temperature fluctuations are therefore avoided and people can enjoy a pleasant and very comfortable environment, which is ideal for spot heating application, where only the objects surrounding the heaters are heated.

Finally, the infraSchwank and the calorSchwank can work with either Natural Gas or LPG.

ThermoControl Plus is designed for use with Schwank tube heaters. The controller can reduce running costs by determining when the heating system should be set into operation with a self-learning function. The ThermoControl Plus is an intelligent control system that allows the tube heaters to adapt to the particular application they have been installed in.

It has practice-orientated service modules and a self-explanatory menu navigation that facilitates the daily handling of the heating system as well as the communication modules for remote service and Building Management System. It can also be easily retrofitted with existing Schwank heating systems. It also switches automatically to and from Daylight Savings Time and allows eight specific “holiday programs”.

The operation of ThermoControl Plus is simple and self-explanatory. Day, night and frost protection temperatures are clearly arranged and easily set. The clearly laid out display is easy to read and shows all relevant data.

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 M allows for adding an external alarm contact to a Building Management System [BMS] or external fire alarm system.

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

For transparent information regarding your heating control system, look no further than the SchwankControl, made in Germany, and available from Devex Systems. Gather and analyse a broad variety of information about the performance of your heating control system, such as consumption for efficient heating operation.

unoSchwank and moduSchwank are the most basic controllers Schwank offers. They are ideal for spot heating where a thermostat is not needed to control the heater. The unoSchwank is used with single-stage Schwank heaters and is a switch on/off button. The moduSchwank is to be used with modulating Schwank heaters and is a rotating knob that you can adjust to control the output of your heater.
