Teaching equipment : Air treatment unit

Air treatment unit

DESCRIPTION The air treatment unit comes complete with instrumentation and includes a technical and instruction manual. Components meet industrial standards. Operation of unit is similar to equipment of greater capacity. Zone of depression treatment. Mixing chamber through aspiration It is possible to measure what goes in, passes through and goes out. Transparent treatment chambers.

Easy access to the components. Use of the refrigerant R 134 a as required by new regulations.
