CHILLERS
GENERAL REQUIREMENTS: Rebates are not available for individual chiller components, like motors and variable frequency drives (VFDs), when the entire chiller replacement is applied for. Chillers must be driven by an electric motor. Absorption chillers, engine driven, and steam turbine driven chillers are not eligible for this incentive but may be eligible for a custom incentive.
AIR-COOLED CHILLERS Requirements:
• Manufacturer specification sheets for items installed must be submitted with the completed Rebate Application. Chiller specification sheets must include performance data, including full load efficiency, IPLV and capacity in tons at AHRI standard rating conditions per AHRI Standard 550/590 test procedures. • “Path A” refers to chillers that are optimized for full load applications, while “Path B” refers to chillers that are optimized for part load applications. • Rebates are calculated based on performance data (including capacity) at AHRI standard rating conditions. • Provide capacity (tonnage) to the nearest whole number and all kW/ton values rounded appropriately to three decimal places (e.g., enter 1.1421 kW/ton as 1.142 kW/ton).

PRO TIP Chillers are typically sized for the hottest day of the year but run lower than full capacity the majority of the time. Selecting a chiller with excellent part-load performance will help maximize energy efficiency.
