Natural Refrigerants
Ammonia and CO₂ — future-proof cooling with zero and ultra-low GWP.
EJM has pioneered natural refrigerant technology for over four decades. As F-Gas regulations tighten, ammonia and CO₂ are becoming the refrigerants of choice for industrial applications.
Ammonia (R717)
Zero rated for both Ozone Depletion Potential and Global Warming Potential. Ammonia has always been our natural refrigerant of choice for industrial systems — two-stage plants, pumped ammonia with hot gas defrost, and low pressure receiver systems.
CO₂ Transcritical
Our recent projects include multiple transcritical CO₂ refrigeration packs for frozen and chilled storage, adiabatic gas coolers, DX CO₂ evaporators and propane-based glycol secondary circuits — as delivered at Cube Cold Theale.
Heat recovery
Modern systems capture waste heat for facility heating, reducing both emissions and operating costs. EJM integrates heat recovery and heat pump technology into complete refrigeration packages.
