R744 Service KitFor service, R&D and production

One of the challenges in the development of any new technology has been the transition

from a pure R&D environment to practical application – and R744 is no exception.

To support your development, AGRAMKOW Fluid System has designed the R744 service

kit, covering sub & trans critical R744 applications. This kit is designed for use in the

appliance, automotive and after sales markets, with functionality, reliability and safety as

the major driving considerations .

The coupling design complies with the SAE-J2769 standard and is tested according to

EC regulations, to ensure lasting performance in the toughest applications.
