Hoval CASER 2.0.9.0

For quick and accurate design of Hoval energy recovery systems, use the Hoval CASER (Computer Aided Selection of Energy Recovery) design program.

Up to 7% more effective rotation exchanger surface, therefore lower pressure drop and higher efficiency
Extremely stable new Hoval rotor casing, therefore high operating reliability
Gotthard now available for air flow rates of up to 24,000 m³/h thanks to combined solution
All Gotthard sizes available with temperature efficiencies of 73% (ErP) and 80%

Selection program for energy recovery systems

  • Secure planning thanks to reliable data (Eurovent- and TÜV-certified)
  • Calculation of a specific Hoval plate heat exchanger or rotary heat exchanger
  • Calculation of all appropriate Hoval plate heat exchangers or rotary heat exchangers for a specific project
  • Efficiency class in accordance with EN 13053
  • Calculation mode “73 air” according to the Ecodesign Directive ErP 1253/2014 (only for plate heat exchangers, for explanation see 1.3)
  • Frost limit (only for plate heat exchangers)
  • Pressure drop increase due to differential pressure (only for plate heat exchangers)
  • Calculation of the performance figures for OACF (Outdoor Air Correction Factor) and EATR (Exhaust Air Transfer Ratio);
  • Simplified ordering process due to optimised type code
  • Price calculation
  • Languages: English, German, Italian, Turkish, Swedish, Slovak, French, Chinese.
