Client: Starbuck's distributor, DPI Mid-Atlantic Operations, Capitol Heights, MD
Testing Dates: October 2019
Tested System: Refrigeration unit

CryoGenX4, an energy control measure (ECM), was tested on DPI's refrigeration system #7, which had lost efficiency due to oil fouling over three years of operation. The technology restored performance by cleaning heat exchange surfaces and preventing future oil buildup, resulting in significant improvements.

Key Results:

  • Capacity Increase: The system's cooling capacity increased by 17.8%, from 13.69 tons to 16.12 tons, restoring nearly all of its original capacity.
  • Efficiency Gains: Energy efficiency improved by 16.6%, reducing energy consumption from 3.2 kW/ton to 2.67 kW/ton.
  • Financial Impact: DPI saved $5,381 annually in energy costs per unit, leading to an estimated ROI >1000%.
  • Environmental Benefit: Each unit treated will reduce 36.2 metric tons of greenhouse gases annually over its lifetime, further supporting sustainability goals.

Why It Matters: CryoGenX4 helps refrigeration and HVAC systems operate more efficiently, reducing energy costs, extending equipment life, and cutting carbon emissions—all with a quick ROI.

CryoGenX4 to the Rescue

The decision to use CryGenX4 yielded impressive results. When initially tested, the refrigeration system #7 was producing 13.69 tons of its designed 16.7 tons of cooling capacity.

Just three days after implementing the CryoGenX4 ECM:

What once took the refrigeration system 20 minutes of runtime to satisfy its set point prior to being treated, it accomplished the same task in 16 1⁄2 minutes.

Less time running translates directly into lower utility costs, fewer repairs and longer life.

CryoGenX4 projected savings for DPI were:

  • Return on investment over equipment lifetime- 2937%
    DPI BMS system
    dpi ice compressor
  •  
  • dpi meters
