Embracing Challenge [ IVteC®] Pre-Cooling Units Series VC Version VC-1, VC-1-SL, VC-2-L, VC-2-SL Special Features ■ With patented Jet-Stream heat exchanger available in 3 standard materials ■ Compact construction ■ Light weight ■ Low maintenance ■ Optimum reliability ■ Version with forced ventilation ■ Version with automatic condensate removal 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-Jet-Stream 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.
