Breadth of Technologies
- Multiple energy recovery options fit a wide range of applications
- Meets ASHRAE 90.1 energy efficiency requirements
- Heat transfer options balance efficiency, maintenance, and leakage
Energy Recovery for High Outdoor Air Applications
When conditioning large amounts of very cold, very warm, or humid outdoor air, energy recovery becomes especially important. Exhaust air energy recovery provides these economic benefits:
Lower operating costs: Energy recovery increases system efficiency.
Lower installed systems costs: Energy recovery reduces mechanical cooling and heating loads and, therefore, reduces the required capacities of cooling and heating components.

Proper Defrost Management
- Winter defrost keeps the supply fan and heat source operational
- Defrost occurs without shutting down the entire unit
- Maintains consistent space temperature and ventilation during defrost
Full-Size Wheels
- Sized to handle the full outdoor and exhaust air volume
- Maximizes enthalpy effectiveness for greater energy recovery
- Low wheel pressure drop eliminates the need for economizer bypass
Meeting Efficiency, IAQ, and Maintenance Requirements
Valent is known for offering a broad selection of energy recovery technologies. When choosing for a specific application, priorities usually fall into three areas:
- Energy efficiency: If energy efficiency is the priority, choose enthalpy wheels, which are the most efficient.
- IAQ: If IAQ is the priority, choose enthalpy core heat exchangers, which allow almost no leakage across airstreams.
- Low maintenance: If low maintenance is the priority, choose enthalpy core heat exchangers, which have no moving parts.
