Valent VXE
Sensible and latent energy recovery
Enthalpy wheel — most efficient energy recovery
DEDICATED OUTDOOR AIR
DOAS WITH ENERGY RECOVERY
TWO INTEGRAL ENERGY RECOVERY OPTIONS
ENTHALPY WHEEL
- Latent and sensible recovery
- Most efficient
- AHRI 1060 Certified
Valent's rotating enthalpy wheels recover up to 80% of return-air energy and slide out for easy access. Two enthalpy wheel types are available: a lightweight polymer wheel with silica gel desiccant and an aluminum wheel with molecular sieve media. Available on Valent VXE units
ENTHALPY CORE
- Latent and sensible recovery
- No moving parts
- Low cross contamination
Valent's enthalpy cores have minimal maintenance requirements and an exhaust air transfer ratio (EATR) of less than 1%. The core is available in two different media types: polymer and fiber. Both are easy to clean and maintain. The polymer core is up to 65% effective. Available on Valent VXC units
