Page Header
Greenheck’s Vektor™-ERS is a pre-engineered laboratory exhaust energy recovery system. In combination
with our Vektor™-MD high plume dilution blowers, this system is designed to effectively remove contaminated
laboratory exhaust and dilute and disperse the exhaust high above the roof.
Vektor energy recovery exhaust systems utilize run around coils to recover energy from the exhaust airstream
and apply the energy to the make-up air system. Vektor ERS offers a safe and efficient solution to minimize the
possibility of cross-contamination between exhaust and supply airstreams. Vektor ERS run around coil loops can
achieve energy recovery efficiencies up to 50% to lower heating and cooling costs for the laboratory facility.
Did you know…
Laboratories typically require 100% outside air with ventilation rates
ranging from 6 to 15 air changes per hour.
ASHRAE 90.1 indicates that energy recovery to pre-
conditioned make-up air is a suggested energy savings
method for laboratories in excess of 15,000 CFM.
NFPA 45 states only general exhaust can utilize air-
to-air energy recovery due to the potential of cross
contamination, which is a violation of standard. Vektor
ERS utilizes air-to-liquid energy recovery, eliminating
the possibility of cross-contamination and recover
more exhaust energy.
Studies show that approximately 50% of the energy
costs associated with operating a
laboratory are by the heating
and cooling of makeup air. The addition of
energy recovery can
significantly reduce
this cost.
Model Vektor™-MD is listed
