All connections to the pipes are made of steel.

R744 is an odourless and colourless gas and cannot be perceived directly in case of emission!

R744 is an odourless and colourless gas and cannot be perceived directly in case of emission!

Lost of consciousness and danger of suffocation by inhaling higher concentrations!

Avoid R744 emission and uncontrolled deflating, particularly in closed rooms!

Aerate closed machine rooms!

Make sure that the safety regulations in accordance with EN378 are complied with!

Liquid R744 evaporates quickly, cools down at the same time and forms dry ice!
danger

Liquid R744 evaporates quickly, cools down at the same time and forms dry ice!

Danger of cold burns and frost bites!

Avoid uncontrolled deflating of R744!

When filling the system with R744, wear gloves and goggles!

In addition to the safety references listed in this document, it is essential to observe the references and residual risks in the respective operating instructions!

ECOLINE SL

Shut-off valves for R744 compressors, subcritical application (SL models).
For most compressors there is only one listed standard valve (in contrast to e.g. compressors for transcritical application).
