R1234ze
Solstice® ze (R-1234ze)
Ultra low GWP (7), energy-efficient alternative to traditional refrigerants for air-cooled and water-cooled chillers in a range of applications and have already been used in supermarkets and commercial buildings.
Features and Benefits
- Ultra Low GWP – Long term sustainable and compliant with F-Gas legislation
- Single component refrigerant – can be used in direct expansion and flooded systems. No temperature glide.
- Comparable energy efficiency to R-134a – Lower indirect emissions and lower operating costs.
- Approved by many equipment manufacturers – Large choice of new equipment available.
- Non-flammable at 20°C ambient temperature – PED fluid group 2 and classed as non-flammable for transport.
Packaging and Supply
Climalife supply Solstice® ZE in 12kg and 58kg returnable cylinders or 890 kg returnable drums.
Conforms to AHRI 700-2016 specifications.
Why Choose Climalife?
Climalife are a key player in the distribution of refrigerants and other climate control products, with a nationwide distribution network and product knowledge that is second to none.
How does Solstice® ze compare to R-134a?
Solstice® ze has a slightly lower cooling performance compared to R-134a but good energy efficiency making it an ideal ultra low GWP alternative to R‑134a in new equipment. Solstice® ze does have the safety classification A2L due to its low flammability at elevated temperatures but is classed under the PE(S)R, CLP package and labelling and ADR transport regulations as non-flammable. It should only be used in systems specifically designed for Solstice® ze.
Full theoretical performance comparisons at customer specified conditions are available from Climalife on request.
