More than 85 years ago, company founder Günther Schwank came up with the idea of using the radiation principle of the sun to heat large buildings, which led to the creation of exceptionally efficient heating systems for industry, commerce and across a range of sectors. Even today, our most efficient radiant heaters [bright radiators & dark radiators] work with the infrared principle. Our energy-efficient heating systems of ceiling-mounted radiant heaters are used in industry, logistics, sports halls and workshops. Infrared heaters of smaller dimensions are used to heat terrace spaces and other outdoor areas of hospitality venues.
Our portfolio of efficient heating solutions extends beyond gas radiant heating products to include unique heat recovery systems, gas heat pumps, air curtains and warm air units, each providing excellent heating solutions for companies in industry, logistics and trade.
Schwank heating solutions and products
Radiant ceiling-mounted gas radiant heating systems for halls
Tube heater systems
Multi-talented in the field of radiant heaters
The Schwank dark tube heater solutions focus on efficiency, comfort and reliability. Every heating system that we plan for our customers is adapted to the individual conditions on site.
Luminous (plaque) heater systems
The most powerful radiant heating
The infrared bright radiant heating technology was invented at Schwank and you can still see it in action today. Schwank luminous gas radiant heating systems are characterised by exceptional efficiency and exhaust gas values. Seasonal energy efficiency values [ErP] of over 99% speak for outstanding manufacturing technology.
Condensing technology & heat recovery
Turbo charging for infrared ceiling-mounted heaters
Schwank condensing and heat recovery solutions help hall heating systems to become even more efficient. They can be implemented for almost all fields of application and are planned and designed individually for each customer.
Gas heat pumps
Top quality heat pumps
Gas heat pumps from Schwank can heat and cool efficiently – and both at the same time. They combine the highly efficient energy source of gas with the use of free environmental heat. Economy is a feature. Gas heat pumps from Schwank ensure the right temperature in both winter and summer.
Warm air units
Alternatives to radiant heating
The SchwankAir product family is impressive in its robust design and proven technology. These products are a great option wherever investment is a priority and ceiling heights are low.
Expansion of the Schwank radiant heating system
The SchwankAir product family also includes the door air curtain systems as cold or hot-operated units. They are a useful addition to the Schwank ceiling-mounted gas radiant heating systems in order to prevent unwanted air changes.
Outdoor infrared heating
Patio heaters are already standard for many restaurant, pub and café terraces. And this trend is continuing. The number of guests who prefer to sit outside even on cool days is increasing. This is due on the one hand to strict smoking laws and on the other hand to the fact that guests want to enjoy that relaxed “holiday feeling” all year round and favour heated outdoor zones.
Gas radiant heating systems
From patent to todays most efficient heating solution: gas radiant heaters
We have copied the principle of Schwank radiant ceiling-mounted heating systems from nature. Infrared radiant heaters have surface temperatures of up to 900 °C. No heat is emitted into the air from this heat radiation – the infrared heater only heats surfaces.
This natural method is one of the best ways to heat halls in an energy-saving and sustainable way. With the benefit of the heat being generated by the infrared heating exactly where it is needed, a comfortable and above all healthy room climate is created economically by means of gas-fired overhead radiant heaters.
Further benefits that infrared heating offers in industry and trade include:
- fast heating up times by powerful infrared radiant heaters
- no dust turbulence, because no air is moved
- warm floor temperatures
- uniform temperature distribution by several infrared radiant heaters
- infrared heaters work silently
- lower power consumption than a warm air heater
Properties of radiant heating
Why are ceiling-mounted radiant heaters so efficient?
Heat rays from Schwank infrared heating systems travel through the air in the building with nearly no heat losses. The rays fall on the surfaces in the building and the air is heated only indirectly. This principle helps the Schwank gas radiant heating systems to save energy costs. Scientific studies prove that a reduction of air temperature by 1°C corresponds to a reduction in energy costs of 7%.
Heating takes place where it is required
Hot air rises upwards. This effect is known as thermal stratification and is the essential reason that warm air units, for instance, operate significantly less efficiently than the Schwank infrared systems. The way warm air units operate means that the expensively heated air is not fed into the common area of the employees, but rises beneath the ceiling. The heat becomes noticeable at ground level only when the majority of air in the building is heated. Schwank gas radiant heating systems work much more effectively. The heat rays travel through the air and fall on the surfaces at the ground level, where they are required. The air itself is heated only indirectly. Thermal stratification is therefore suppressed.
Preventing heat losses
The higher the temperature difference between two mediums, the stronger is the effort required to offset this difference. This effect is known as transmission. This also applies to the balance between the room temperature [TA] on the one hand and the outdoor temperature [TB] on the other. Owing to the targeted infrared radiation of the Schwank gas radiant heating systems, the building envelope does not get heated unnecessarily; the difference between the temperature of the outdoor air and interior air is therefore kept very low, so transmission losses are minimised.
Short reaction and heating times
In contrast to central heating systems with heat transfer mediums such as water, the decentralised infrared systems by Schwank generate heat where it is required. The advantages are obvious: The transport of heat from a centralised boiler to the operation site is omitted, thereby reducing the reaction and heating times. As a result, operating times of the heating system are minimised.
No distribution and transmission losses
Transport and transmission losses arise in central heating systems due to long transport routes from the heat generators to the required site and to additional transmission stations. By contrast, Schwank’s decentralised infrared gas radiant heating systems convert the primary energy used into heat directly at the required site. Losses that occur due to the transport or transmission of the generated heat are therefore completely eliminated.
Heating takes place only where it is required
Schwank infrared gas radiant heating systems can be used to heat sections of the building or even individual workstations. Just like electric light, infrared heaters can be switched on and off without distributing the heat in the entire room. This ensures requirement-based heating depending on the building usage, shift times, or other similar factors. In this way, the solutions by Schwank actively spare operating costs since the most economical heating system is the one that is switched off.
