Valent VXE
Sensible and latent energy recovery
Enthalpy wheel — most efficient energy recovery
DEDICATED OUTDOOR AIR
DOAS ROOFTOPS WITH ENERGY RECOVERY
THREE INTEGRAL ENERGY RECOVERY OPTIONS
ENTHALPY WHEELS
- Latent and sensible recovery
- Most efficient
- AHRI 1060 Certified
Valent's rotating enthalpy wheels recover up to 70% 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 and VPRE units
ENTHALPIC PLATE
- Latent and sensible recovery
- No moving parts
- Water-washable
Valent's enthalpic plate heat exchangers have minimal maintenance requirements, an exhaust air transfer ratio (EATR) of less than 1%, and can safely handle accumulated condensate without sustaining frost damage. Available on Valent VPRC units
SENSIBLE PLATE
- Sensible energy recovery
- No moving parts
- All aluminum construction
Valent's sensible plate heat exchangers allow minimal cross-air leakage, have a low pressure drop, and are easily cleanable. Commonly used in dry climates, they are also effective in high humidity spaces such as pools, or where cross-contamination is a concern. Available on Valent VPRP units
