With the method of numerical flow simulation (CFD) we have e.g. investigated the effects of new turbulators on the fins. The results were validated by wind tunnel measurements.
A patent was applied for the new Invention.
lighter, higher efficiency and more silent than conventional products
high efficiency in heat transfer and flow performance
up to 25 % less requirement of heat exchanger tubes
up to 30 % less electrical power consumption of the fans
reduced investment and operating costs
reduction of CO2- and noise emissionroduct benefits:
Thermodynamic properties and air-side pressure losses are similar to the FE tube type
Larger clearance between the elliptic core tubes for applications with increased soiling hazard – provides good cleaning possibilities
Is preferably used for combustion air heaters and air coolers
The steel strip is wrapped around the core tube as a spiral. Subsequent hot-dip galvanizing ensures heat transfer and corrosion protection.
Fin material: Steel
Core tube material: Steel/stainless steel
Maximum operating temperature: 360 °C
