New casing for Hoval rotary heat exchangers

New casing for Hoval rotary heat exchangers

We have developed a completely new casing for our rotary heat exchangers.

The revolutionary design principle is convincing:
  • Up to 7% more heat exchanger surface area due to up to 50mm larger diameter of the storage mass
  • High operational reliability and leaktightness due to extremely stable casing
  • High efficient gearless stepper motors with internal electronic run monitoring
The casing concept for the future - more stability and better performance.

Up to 7% more effective surface area

The narrower housing makes room for larger rotors - without changing the overall dimensions. A 50mm larger diameter storage mass doesn’t sound like much, but means up to 7% more effective surface area for energy recovery. The result are better efficiencies and a lower pressure drop.

High-efficient stepper motor

The gearless 3-phase stepper motors require little space in the casing. Despite lower energy consumption, they offer an optimum torque characteristic for a continuous drive. Electronic run monitoring is already integrated.

All Hoval rotary heat exchangers (Muonio, Emån and Viskan) will be supplied with the new SheetMetal casing.

Now available and included in the new CASER.
