After over 20 years of reliable operation, the energy recovery ventilation (ERV) system serving Harley Davidson’s corporate headquarters was due for an upgrade. Joe Langfeldt, an HVAC engineer for Harley Davidson, contacted Airxchange to determine if there was a way to restore or replace the energy recovery wheels in the system, in order to avoid the high cost of a complete ventilator unit replacement. Unique design feature of the Airxchange wheels He learned that a unique design featur...

Modern manufacturing facilities are highly automated and use large numbers of variable speed drives (VSDs), programmable logic controllers and equipment with embedded microprocessors. These kinds of devices can all produce harmonic pollution that leads to nuisance breaker trips, device malfunction, data loss and premature equipment failure. Another PQ issue is poor Power Factor (PF) – a measure of electrical system efficiency. The main contributors to lower PF are inductive loads such as...
