High Efficiency Run Around Energy Recovery Systems
The need for high efficiency energy recovery systems (RAER’s) in today’s buildings is greater than ever.
Escalating energy prices and the demands of energy regulations have challenged conventional methods
of energy recovery. Steve will present on the fundamentals of heat recovery and some new technologies
for energy savings.
Typical glycol run around systems operate at 30-45% effectiveness. Some highlights:

65-75% effectiveness with a glycol loop system – and a guarantee of savings!
Highest efficiency, lowest life cycle cost energy recovery
No cross contamination of air streams
Year round efficiency - Optimized performance under varying operating parameters
Greater flexibility in mechanical room design and arrangements
Turn Key source - a complete package – Many suppliers manufacturer their own coils, pump
packages and advanced controls and software
Coil construction is specifically designed for glycol usage, and optimized for variable flow
Many customers with projects using higher volumes of outside air have found these systems to provide
significant energy savings and attractive paybacks.
