15 Old Artisan Heating Project New York, New York New 11,152 sq ft heated area, school for Autistic children Original Pump Specification > Three 7 ½ Hp, 250 Usgpm at 70 TDH, constant speed in-line pumps > Amperage (measured) 14 Amps Retrofit ECM Pumps > ECM in-line pumps, SET AT 13 TDH! > Amperage (averaged) 2.0 Amps > Operating at 340 Watts about ½ Hp Customer Comments > Much better comfort due to the ability of controlling the system, hot and cold spots have been eliminated. Recorded Amperage/Energy Savings (based on $0.20 per Kwh, 5040 Hrs/annum) > Original pump 2327 Watts/Hr/1,000 x 5040 Hrs x $0.20 = $2, per year for power > New ECM pump 360/Hr/1,000 x 5040 Hrs x 0.20 = $ per year > Annual savings $1,982.74! One Pump! Times three!

16 Variable Speed Pumping Why use VFD s? GREEN! Pumping systems account for 22% of the world s electrical power demand Air Compressors 18%, Fans 16%, Cooling Compressors 7%, Other equipment 37% In some industrial plants pumps account for over 50% of the electrical load Rotodynamic (centrifugal) pumps account for 73% of all pumps Positive displacement (usually piston or screw types) account for 27% Over 95% of all pumps are oversized due to multiple butt covering! Up to 80% energy savings can be achieved using proper VFD techniques The pump can run closer to it s Best Efficiency Point more frequently The result of the effect of the Affinity Law is if we can operate a 125 Hp pump at half it s speed and maintain the desired result of it s overall function it consumes only 5 Hp!

17 IEA (International Energy Agency - Facts and Figures) Factoids on European Heating and Energy 78% of household energy costs is heating the home 90% if DHW (domestic hot water) is included 120 million heating pumps running in Europe 60,000 giga watt hours annually! According to IEA, ECM technology has a potential of 70% savings 42,000 giga watt hours annually Equal to all washing machines and dishwashers in all Europe North America Assume 3 million circs sold annually Average circ life 10 years Wattage per circ 100 Watts Totals 3 BILLION watts of power Smart pump technology reduces power consumption by 2/3! Does not include systems savings Does not include all other larger pumps
