The Technology of Gas-Infrared Luminous Heaters
Schwank luminous heaters are a synonym for high performance as we reach overall system efficiencies of a minimum 95%, and the highest infrared radiant efficiency in the world.
The Delta-Mixing-Chamber
The more uniform the gas-air-mixture of the infrared heater, the better the radiant heat production. The patented delta-mixing-chamber (1) of Schwank heaters looks after that. The venturi (2) takes the precise proportions of gas and air and delivers a combustible gas-air-mixture that is pre-heated, pressurized and evenly distributed in the delta-mixing-chamber. Through this gained boost in fuel delivery the energy is evenly distributed at each and every point of the ceramic tiles (3), even at low gas-pressures.
A Number of Small Suns with a Substantial Impact
From the delta-mixing-chamber the gas-air-mixture streams through thousands of small passages in the ceramic tile burner (4), the heart of each gas-infrared-heater. On the surface of the ceramic tile, the gas-air-mixture combusts and generates thousands of small flames (5). Comfortable radiation-heat (6) is set free at a surface-temperature of approximately 950°C (1750°F).
Additionally, the unique surface structure and the exclusive formulated recipe of the ceramic tile optimize the radiation-exploitation. Due to the fast heat transfer in the ceramic tile, combustion is “cooled down”. This means that controlled combustion of natural gas (or LPG) results in significantly low emissions. NOx values are below 10 ppm. With Schwank gas-infrared heaters you have chosen modern heating system technology with extremely low emissions. Choosing Schwank will enhance your reputation as a responsible corporate citizen while reducing your operating and life-cycle costs – a “win/win’ situation indeed.
The Combined Radiation
The special construction of Schwank gas-infrared-heaters makes possible the conversion of convection heat into radiant heat: the reflectors (7) are warmed up to 500°C (930°F) and the additional radiant output (8) increases the efficiency significantly. Therefore our gas-infrared-heaters work on the basis of two radiation-mechanisms: ‘high’ and ‘low’ intensity – this unique technology is called “combined intensity”.
Safety and Control
Operational safety is a top priority in all of our gas-infrared-heaters. The operation of each burner panel is monitored by a microprocessor operated ionization-flame-control. When gas pressure or voltage deviates, or combustion stops, the gas valve automatically closes. Raw unburned gas is not able to leave the system. According to individual project requirements, our heating systems can be regulated by single thermostats, our unique TruTemp infrared set-back thermostat, or even by a central building control.
The Luminous Heater Design
We designed the highest level of quality into our products: With sophisticated specialty tools all appliance parts are produced from high quality aluminum-coated sheet metal and assembled in a “press-joint process“. This construction guarantees high corrosion protection and ensures high quality standards for many years of reliable operation.
