Additional Benefits• Longer Equipment Life: Unlike constant speed

equipment that use full-speed starts, variablespeed drives allow for gradual ramp up to fullpower, resulting in less wear on the equipment’selectrical system. Additionally, by operating atslower speeds, component wear is furtherreduced, resulting in lower maintenance costsand added reliability.

• Quiet Operation: In addition to energy savings,you’ll notice that your equipment room is muchquieter since the equipment’s motor will runslower 95% of the time.

Professional ResourcesOur highly technical and experienced representatives are geared to your budgetary andenvironmental concerns.

• Experience: Since 1990, we’ve installedhundreds of variable speed drives

Slow down those Towers,Pumps, Air Handlers and ChillersConstant speed is a thing of the past. Your building operates at full load less than 5% of the time. Yet, constant speed equipment is running at full speed all the time. Doesn’t it make sense to match your motor’s speed to the actual building load and requirements?

Lower Utility BillsWhen you match your motor’s speed to actualcooling requirements you use significantly less energy.And, when you consider that your equipmentoperates at off-design conditions more than 95% of the time, the savings quickly add up, usuallyproviding payback in less than two years.

Environmental ResponsibilityYour building’s HVAC system is its largest energyconsumer. Variable Speed Drives can help lowerenergy consumption, reduce your carbon footprintand preserve the environment.
