World novelty: The refrigerant of the future WT69.
The future-proof substitute for R23.
Without compromise to –70 °C.
With WT69, the test results remain reproducible.
Our first premise and the biggest challenge in the development of the new refrigerant was the complete maintenance of test results comparability. The reproducibility of the test results is our big promise.
No wonder, then, that we do not compromise on reaching -70 ° C with the new refrigerant. With WT69, our test cabinets behave almost identically to the predecessor models with R23. The cooling rate stays long linear, with high heat compensation. This way you can continue to use all test profiles without restrictions, and the results remain comparable.
GWP reduction of more than 90%.
With a GWP of just 1,357, WT69 complies with the EU F-Gas Regulation.
WT69 has an extremely low GWP of only 1.357. Compared to R23, we achieve a CO2 equivalent reduction of over 90% (14,800 to 1,357). By using WT69, you can continue to operate your systems safely beyond the year 2030 and are spared the future price increases and availability problems related to R23.
WT69 fulfills all requirements for refrigerants in environmental simulation systems.
In the environmental simulation chambers, products are tested under extreme conditions. The extreme temperatures prevailing in the test room also present special challenges to the refrigerants in use. For example, they must not be flammable or toxic.
The new refrigerant WT69 meets all refrigerant requirements for environmental simulation. It is
- Non-flammable: A1/A1 proven by ASHRAE
- Non-toxic: material safety data sheet officially released
- No ODP: formula without ozone-depleting substances
- Non-corrosive: 100,000 hours tests without corrosion
- Chemically stable: ASHRAE and BAM tests passed
In addition, the pressure in the system remains manageable, the pressure remains as before.
First test chambers TempEvent and ClimeEvent with WT69 available.
The best refrigerant does not make sense if it does not work in practice. Having that in mind, we also tested the suitability of WT69 in our test chambers. In 100,000 hours of testing over the past three years, we have tested more than 20 system configurations – all with the same result: The test chambers run flawlessly with WT69. What's more, from now on you can order first TempEvent and ClimeEvent models running with WT69.
