Krack expands condensing unit offering with more lower horsepower scroll compressors for DOE 2020 and new CARB 50 pound charge requirements.
High Efficiency (HE) H-Series Condensing Units are designed and tested to provide an Annual Walk-In Energy Factor (AWEF) required to label units for WICF applications and a great solution to meet California’s CARB 50 pound new store charge requirements.*
The minimum AWEF ratings vary for coolers ranging from 32˚F to 55˚F and freezers below 32˚F by condensing unit location (indoor or outdoor). Refrigerated spaces (55˚F or less) and 3,000 square feet or less regardless of application are in scope for the new regulation which covers air cooled condensing units. Out of scope for this regulation are water-cooled, remote condensing, satellite units or condensing units designed to serve more than one refrigeration load. There are no restrictions on using the more efficient units for non-regulated applications like refrigerated display cases or larger WICFs.
Krack has made substantial investments in design and testing to ensure a broad range of condensing units are available to provide application solutions for your WICF needs. Krack’s exceptional sales, application, and design teams are ready to answer any questions and assist in selection of units for the new regulation.
* New store 50 pound charge requirements go into effect January 1, 2022.
