Energy Recovery Ventilators
Model ERV packages a total enthalpy wheel with exhaust and supply blowers, motor starters, and a control transformer pre-wired at the factory. An inline arrangement for interior installations as well as three exterior mounting arrangements are available. These arrangements enable the consulting engineer greater flexibility for designing energy recovery into the HVAC system.
Energy recovery ventilator is specifically designed for outdoor installations. The weather-resistant Model ERVe features a pitched roof and drainable base for better protection against water penetration. In addition to its one-inch double-wall construction and hinged access panels other features include optimized blower performance for each housing size and multiple energy wheel options for selections based on horsepower, efficiency or recovered energy ratio (RER). Performance ranges from 1,000 to 6,000 cfm
Model ERV: Interior Installation - Arrangement A
Direct and belt drive models are available for interior mounting. This compact design is ideal for the space limitations that routinely complicate interior installations. Specify arrangement A for interior mounting. All ERV sizes are available.
Model ERV: Exterior Installation - Arrangements B,C,D
Direct and belt drive models are available for exterior installations. Where roof mount or pad mount installations are preferred, these arrangements provide the flexibility to simplify system design and installation. Intake and exhaust hoods are standard. The housing and hood design minimize re-entrainment of exhaust air.
MiniVent-450 & MiniVent-750
Direct drive models are available for interior mounting. This compact design is ideal for the space limitations that routinely complicate interior installations.
Energy recovery ventilator utilizes an air-to-air, aluminum plate heat exchanger to transfer (heat) energy form the exhaust airstream to the supply airstream. Features for the PVe include; weather resistant housing, 1-inch double wall construction, stainless steel condensate drain pan, lift off doors, belt drive, quiet operating forward curved blowers and much more. The PVe has very low leakage rates allowing it to be used in light industrial application as well as common energy recovery application. Performance ranges from 1,000 to 6,000 cfm up to 2 inches of water gauge

ETL Listed Products
To guarantee your customers are getting the performance they request, check for ARI Certification. ARI Certified products are tested for energy transfer effectiveness (sensible, latent, and total), cross leakage, and pressure drop. If a manufacturer states that their products are tested "in accordance with" ARI Standards that DOES NOT mean they are certified. To be certified, products must be tested by ARI and have annual check tests.

A psychometric chart is a design tool to graph a building's HVAC thermodynamic air conditions and processes. Properties displayed on a chart include dry-bulb temperatures, wet-bulb temperatures, dew point temperatures, relative humidity, humidity ratio, specific volume, and enthalpy. A link is provided to a downloadable software program that allows the user to electronically plot conditions on a psychrometric chart. This program version permits the user to enter state points and graph the air conditioning process, while also calculating additional air properties.
