    SAP Reward: Outstanding Energy Performance
  • With a Specific Fan Power as low as 0.69 W/l/s and heat exchange efficiency as high as 88%, the CA350 Heat Recovery unit easily achieves EST Best Practise Performance and offers specifiers and designers excellent reward in SAP through the Dwelling Emission calculation.
  • Summer By-pass and high grade filtration
    The CA350 has been designed with a filtered summer by-pass which ensures that overheating in the property in warmer summer months is eliminated. By by-passing the heat recovery mode, ventilation is continuously provided without warm and humid air entering the property unnecessarily. In addition to summer by-pass, the unit is also provided with grade GU4 filters as standard. Filtration of incoming air is crucial to ensuring a good level of indoor air quality at all times for occupants and especially essential in highly insulated dwellings where Heat Recovery is installed. Once the summer by-pass is activated, the fresh incoming air continues to be filtered (unlike a high number of other units)
