ESP+ Commercial Refrigeration Technology

Designed to replace traditional electro-mechanical refrigeration controls typically used on medium and low temperature applications, we introduce to you KeepRite Refrigeration’s latest technology innovation – ESP+.

As we continue to create innovative, state-of-the-art designs, we have successfully combined award winning adaptive technology with an electronic expansion valve bringing this technology invention to life.

As part of our Smart3 Suite of Systems Savings Solutions, ESP+ helps control many different aspects of the system, including box temperature, superheat, defrost initiation, defrost termination, fan motors and defrost heaters (where applicable). We won’t leave out the fact that the user can access operating data directly from the system interface as well.

  • Easily troubleshoot issues
  • Complete isolation from condensing unit

ESP+ Installation

There’s not a whole lot of other technologies out there that are as easy to install as ESP+. Braze two pipes, connect the single point electrical service, mount the suction line temperature sensor and you’re good to go.

No interconnecting control wiring between the evaporator and the condensing unit is required. Installing an evaporator utilizing the ESP+ intuitive evaporator control technology could not be any more simple.
