SustainabilityGiant step forward, smaller
footprint

• Indirect Emissions Contribute 98 of Chiller GWP
• Electricity generation is the largest sourceof
  greenhouse gas emissions
• Efficiency of YVAA chiller offers substantial
  reductionin power consumption your
  environmental footprint

• Direct Emissions Contribute 2 of Chiller GWP
• HFC-134a refrigerant has ZERO ozone-depletion
  potentialand no phase-out date
• Falling-film evaporator reduces refrigerant
  charge by up to 15

• Water Consumption
• Power generation can deplete water resources
• An indirect benefit of the YVAA chiller water
  conservation
• Gain the efficiency of a water-cooled chiller for
  the costof an air-cooled

Low SoundLower the volume, increase goodwill

• Off-Design Conditions Occur 99 of the Time
• Most stringent sound requirementsoccur on
  evenings and weekends
• Standard VSD compressorsdesigned for sound
  relief areduced speeds
• Optional VSD condenser fanswill provide further
  significantoff-design sound benefit
• Further accessories can providesound reduction
  at on-designconditions

Low SoundLower the volume, increase goodwill

• Sound Level That You Can Control
• Our proprietary SilentNighttechnology
  automatically integrateswith your BAS (or
  programmable)control to load shed
• BAS of load shedding providesNight Set-Back
