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
