The VersiVent Model VER Advantage
One Unit for Your Ventilation Needs
The need for energy recovery in the HVAC market is being highlighted by increased outdoor air requirements,
along with the attention to energy costs through LEED initiatives and ASHRAE guidelines. Increased ventilation
rates in combination with energy recovery products will improve your indoor air quality (IAQ) without the
associated costs of conditioning outdoor air. Greenheck’s VersiVent air-to-air energy recovery model continues
our leadership in the industry by supplying equipment that promotes productive and healthy environments.
The semi-custom configuration of the VersiVent offers the quality construction, flexibility and performance found
in a custom unit, without the cost or lead-time. With a variety of standard and optional accessories, the VersiVent
has been designed to meet your application needs.

Why Use Energy Recovery?
• Energy Savings = Quick Payback
When a total energy recovery wheel is implemented in an HVAC system, it provides both initial cost savings by
cutting cooling tonnage and also annual savings by preconditioning the outdoor air. Combining these two cost
saving features leads to an attractive payback on these units. Energy recovery units should be viewed as an
investment and not just another piece of HVAC equipment.
• Improved Indoor Air Quality (IAQ)
Introducing fresh, outdoor air to a building
is a key component to sustaining excellent
IAQ. Preconditioning outdoor air with the
VersiVent (model VER) energy recovery
unit offers an economical approach for
providing high rates of outdoor air.
• LEED Credits
For Green Building designs, the VersiVent
offers an excellent way to acquire credits
in both the Energy and Atmosphere (EA)
and Indoor Environmental Quality (EQ)
categories towards a LEED certification.
• Adhering to ASHRAE Guidelines
ASHRAE Standard 90.1 provides design
guidelines regarding when it is most beneficial to use energy recovery. Depending upon your geographic
location, and the percentage of outdoor air in the application, ASHRAE recommends when to use energy
recovery. An important part of this guideline is that when energy recovery is recommended, the device should
be a minimum of 50% total (sensible and latent) effectiveness according to AHRI 1060 testing procedure.
