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.
Description
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.
The condensate formed should be removed
with a small peristaltic pump, sample trap or
collection vessel.
The VC-..-SL pre-cooling unit has as a standard
peristaltic pumps SR25.1 for automatic condensate removal.
The VC-..-..L pre-cooling unit has got
a fan to force the ventilation of the cooling fins for performance rise. In this case,
a deflector is integrated for an optimal
air conduction.
The VC-1-.. pre-cooling unit is equipped with
one EC-Jet-Stream heat exchanger. The VC-2-..
pre-cooling unit is equipped with two EC-JetStream heat exchangers to connect two independent sample streams or parallel or series
function to connect one sample stream with
a corresponding high flow rate.
The compact lightweight design of this
device makes it ideal for use in portable and
continuous sample conditioning systems.
The pre-cooling units are self-controlling with
low maintenance.
