6 INTRODUCTION
The VC-... pre-cooling units produced by M&C incorporates the “Jet-Stream’’ design of heat
exchanger. This design induces condensate formation and guarantees optimum dew point reduction to
ambient temperature.
7 APPLICATION
The M&C pre-cooling units VC-... are used in gas analysis to lower the dew point of humid gas, for
example:
• to relieve downstream main cooling system
• if process-bound water or steam irruption can become forward,
• if non-heated sample lines without adequate slope are mounted,
• for gas analysis system with electrochemical sensors.
