New Model IV Indoor Ventilator Offers Compact Outdoor Air Solution

Model IV is the newest addition to Greenheck’s line of indoor ventilators that deliver 100% outdoor air and are designed for indoor installation in limited spaces such as mechanical rooms, attics or basements. Model IV, without energy recovery, joins Model IVE, which features a compact 3-inch polymer total enthalpy wheel that transfers both heat and moisture with up to 85% total effectiveness. Models IV and IVE have hot water and chilled water coils as well as electric post-heat up to 45 kW.

Greenheck’s indoor ventilators have a modular design that fits through 30-inch service doors and elevators and can be ceiling-hung. Models IV and IVE are ideal for retrofits, IAQ improvement projects, VHE stretch code initiatives and applications such as:

• Schools, hospitals and nursing homes where 100% outdoor air is required
• Buildings with roof constraints, such as a pitched roof
• Multilevel high-rise buildings where rooftop DOAS is impractical or difficult
• All-electric decarbonization initiatives
