Increasing the quality of life, securing human health, operating refrigeration and air conditioning installations as efficient as possible, while protecting the environment.

With our longtime experience in fluorine chemistry, Solvay Fluor is an ideal partner for the refrigeration and air conditioning industries. We are continuously intensifying our activities for creating innovative products to support our customers to be ready and competitive for future developments.

Our SOLKANE^® refrigerants product line offers high performance cooling solutions for the complete refrigeration and air conditioning temperature range from -80 to 30°C. Using SOLKANE^® refrigerants guarantees optimized economic and energetic performance, while maintaining the highest safety standards.

Our Solkane^® refrigerants product portfolio is now extended by the two products Solkane^® 22L, as easy replacement of R22 in existing refrigeration systems, and Solkane^® 22M, as easy replacement of R22 in existing a/c systems. Both products are “ODP 0” HFC solutions, compatible with commonly used lubricants.

General Information:

This brochure provides information on the characteristics, the handling and the transport of Solkatherm® SES36. The information provided is not intended to replace existing standard operation procedures and can not cover every detailed aspect. We would like to advise you to contact our technical service team in case of any additional questions.

What is Solkatherm® SES36?

SOLKATHERM® SES36 is an azeotropic mixture of Solkane® 365mfc which boils at 36.7°C. This means that its handling is particularly easy because: 

• Azeotropic mixtures behave like a single-substance. The liquid and vapour phase have the same composition; transferring, evaporating or condensing Solkatherm®SES36 will not affect its composition.
• Substances which can be transported as liquid have, by definition, at 50°C a vapour pressure lower than 3 bar. They can be filled into containers which are not pressurized gas cylinders. These containers have to comply with minimal burst pressure requirements and they are easy to handle.

SOLKATEHRM® SES36 has the following main characteristic:

• It is a non flammable liquid, but its vapours form flammable mixtures with air in the range 3,9% (LFL) – 11,7% (UFL). The Minimum Ignition Energy (MIE) of Solkatherm® is very high: 130mJ. For comparison, we report hereafter the MIE of other reference materials: methane 0,4mJ; R152a 0,35mJ; n-pentane 0,22mJ. Only strong electric discharges and naked flames have the energy to ignite Solkatherm® vapours.
• The flame does not propagate to the liquid phase.
• It is not listed as toxic substance; it does not represent a health hazard if used properly.
• It has a characteristic odour of ‘solvent’. It can be detected by smell before it reaches large concentrations in air. Its vapours are heavier than air and have the tendency to disperse at ground level.
• It is colourless, it looks like water. It boils fast and at a relatively low temperature subtracting heat from the environment. In this, its behaviour is similar to many other well-known solvents like alcohols or ethers.
• It is chemically stable. It is compatible with most construction materials.
• It is thermally very stable. Its first decomposition reactions occur in laboratory at 220°C. It has been proved in continuous operation conditions up to 190°C.
• Auto-ignition is at 580°C
