Industry Leader in Ammonia Refrigeration Systems

The industry leader in ammonia refrigeration systems, Stellar has more than 230 self-performing professionals solely focused on ammonia refrigeration. Originally founded in 1985 as an industrial ammonia refrigeration company, Stellar’s expertise in ammonia refrigeration is unparalleled. Our teams have engineered, fabricated, installed and serviced more than 1,000 ammonia refrigeration systems at plants across the world while meeting stringent safety regulations.

Food processors, beverage companies, cold storage, chemical and pharmaceutical companies have relied on ammonia refrigeration systems for decades due to ammonia’s unmatched thermodynamic properties. This unmatched thermodynamic efficiency can reduce energy and operational costs by 3 to 10 percent versus a comparable fluorinated gas system.

With fluorinated gas regulation driving the industry toward environmentally safe refrigerant alternatives, ammonia’s natural properties — including an ozone depletion potential (ODP) rating of zero and a global warming potential (GWP) rating of zero — make the refrigerant ever-more popular.

Stellar's undisputed ammonia refrigeration expertise includes:

  • 1,000+ installations over three decades
  • Experts in condensation control and air balance
  • Installed systems with up to 42,000 tons of refrigeration in a single system
  • More than 230 designers, engineers, installers and service experts
  • Engineered and installed the world’s largest CO2/ammonia cascade system
