  1. COMPACT Variable Frequency Drives

  2. Commercial Buildings consume massive amounts of Energy Electricity = 74% of the energy consumed by commercial buildings (source: US DOE, 2008 Building Energy Data Book) Half of electricity consumed by buildings is used to move air More than half of the worlds energy is consumed by pumps and fans Buildings Consume Massive Amounts of Energy An electric motor is a fixed-speed machine

  3. (VFDs) significantly reduce electrical consumption Most pump and fan systems are oversized to account for maximum loads Capacity usually exceeds demand Application of VFDs converts systems to variable flow Green House Gas Reduction 80% of commercial building CO2 emission due to electricity consumption VFDs Greatly Reduce Electricity Use VFDs provide the ability to vary the speed of a motor

  4. Variable Frequency Drive (VFD) Motor  + V1 V3 V5 3 ~ C V2 V4 V6 - Rectifier DC- circuit Inverter unit What Does a VFD do? Power Supply

  5. Why Do It? Less Energy = Greater Savings Affinity laws Express relationship between rotational speed and flow, pressure and power Flow is directly proportional to speed Pressure is proportional to the square of speed Power is proportional to the cube of speed % Power Savings = (%Speed Reduction)3

  6. Why Do It? Less Energy = Greater Savings % Power Savings = (%Speed Reduction)3

  7. Opportunities are Everywhere • Supply and return fans • Cooling Towers • Compressors • Stairway and parking ventilation • Boiler pumps and fans • Kitchen Hoods • Conveyors • Elevators

  8. Optimize Capability, Minimize Waste • Many Micro VFDs come loaded with features that do not fit the application • Many Micro VFDs do not have the right combination of capabilities • SmartDrive COMPACT - chose the options to meet the application: • Interface • Filter • Enclosure • Inputs and Outputs • 3 Year Warranty • Longer than all competitors

  9. Chose only the options you need Small installed size Fast installation Intuitive commissioning Easy communication 3-Year Warranty Optimize Capability, Minimize Waste

  10. Available Sizes and Options • Power Range • 208/240VAC, 1~in/3~out, .25HP to 3HP • 460VAC, 3~in/3~out, .5 to 7.5HP • NX series available for other sizes • Other niche markets we are examining • 208/240 VAC 3~in/3~out • 575VAC • 110 VAC • Application Interface (API) • Limited API (Standard) • Most Applications • 1 Analog In, 1 Analog Out, 3 Digital In, 1 Relay Out • Full API • Advanced Applications • 2 Analog In, 1 Analog Out, 6 Digital In, 2 Relay Out • Enclosure - Open Chassis or NEMA 1 • Optional EMC Filter
