Ammonia Cascade System

Description

The NH3 system sits on top of the roof while the CO2 system feeds refrigerant into the cases, so that no ammonia enters the store.   The ultralow ammonia charge, the lowest in the industry, means that regulatory reporting and tracking are typically not required.

 

Benefits

  • Environmentally sustainable refrigerants with lowest ODP and GWP characteristics
  • Low energy costs with the highly efficient refrigerants NH3 and CO2
  • NH3 and CO2 require smaller equipment, less piping and fewer compression cycles
  • Proven history with NH3 and CO2 as sustainable chemistries (no potential phase-out)
  • Lower refrigerant replacement costs
  • Offers leading design elements for fewer maintenance service visits
  • SleepWellTM training and support

 

Selection Guidance

  • Hybrid CO2 system (store)
  • Glycol pump station (store)
  • Ammonia system (rooftop)
  • Evaporative fluid cooler with glycol (rooftop)

 

Construction Features

  • Fully automatic oil recovery system
  • Open drive reciprocating motors with variable frequency drives (VFD)
  • Cascade heat exchanger is direct expansion, plate heat exchanger (PHE) with electronic expansion valve
  • Leak detection, purge ventilation and water solubilizing system for roof-top ammonia unit
  • Heat recovered from compressor discharge for use with hot water
  • Commercial refrigeration  control system which enables remote monitoring
  • Weather protection panel for climate protection
