Certified Performance

All Whalen products undergo an extensive internal design procedure and are tested in our state-of-the-art psychrometric laboratory. Each product is independently tested and has AHRI Certified performance, meaning you can rest assured that our products will perform as expected.

Integrated Energy Recovery Module

Our integrated energy recovery module is fully removable for easy maintenance and capable of providing fresh air to the occupied space as well as exhausting multiple bathrooms.

Safe, Reliable Operation

Integrated controls provide freeze protection for the heating and cooling system as well as the energy recovery module. Built-in dampers eliminate wind or stack effect to ensure reliable ventilation rates.

Indoor Air Quality (IAQ)

Whispertherm™ units improve indoor air quality by providing fresh air to your occupied space. Each filter is washable and is standard with anti-mold, fungus, and bacteria protection.

Constant Fresh Air Flow

Each unit is programmed for a minimum constant air flow to provide the required outside air. Optional decorative wall controls provide intermittent high speed exhaust flow from one or two remote locations.

Multiple Ventilation Rates

Each energy recovery module is shipped with a factory-set ventilation rate to balance the supply and exhaust air selected.

Control Valves

The Whispertherm™ unit uses two two-way valves for variable-speed pump systems.

Cabinet

Galvanized monocoque construction: Designed to handle the rigors of installation while providing long-term performance.

Refrigeration Chassis

Versatile removable-floating design with insulated compressor compartment and vibration isolation.

Hydronic Heating Coil

The Whispertherm™ unit uses either a two-row or three-row integral hydronic heating air coil.

Water Hoses

Connecting the chassis to the supply and return water piping: Isolates sound from the building piping system.

EC Motor

Constant torque EC motors come standard, providing five available motor speed settings and maintaining a constant motor torque as external static pressure in the system increases. Constant air EC motors are optional on sizes 04 - 08.

Drain Pan

Internal stainless steel design with P-trap style rubber drain line.

Thermostat

Digital low-voltage thermostat: Plug-in or remote mounted with manual or automatic changeover.

Acoustical Panel

Flush-mounted design: Dampens sound while permitting filter removal without tools. Integrated design allows access to both the energy recovery module and the refrigeration chassis. Multiple grille sizes available. Filters are MERV rated.

Unit Performance Testing

All units are individually tested during the production process to ensure trouble-free start-ups and reliable service.
