DOAS 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
