New casing concept for Hoval rotary heat exchangers
From autumn 2019 the Hoval rotary heat exchangers will have a new casing.
The revolutionary design principle is convincing:
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 ST-Rotor) will be supplied with the new SheetMetal casing.
Now available and included in the new CASER.
