The EC/ECS • is equally suitable for wall installation or mounting in a 19“ -rack. The versions differ in the positioning of the LED function display ‚. While for wall installation the LED function display ‚ can be fitted into the corresponding cut-outs in the EC/ECS front panel, for 19” rack mounting this is done using the cut-outs in the back panel of the housing. -
Page 13: Function
FUNCTION The M&C EC/ECS gas cooler is a compressor cooler with status alarm capability. This ensures a reliable continuous operation of the cooler. Up to 4 Jet-stream heat exchangers made of Duran glass, PVDF or stainless steel are located in a heat-insulated cooling block. -
Page 14: Reception And Storage
RECEPTION AND STORAGE The EC/ECS gas cooler is a complete pre-installed unit. • Carefully inspect the EC/ECS and any special accessories included with it immediately on arrival by removing them from the packing and checking for missing articles against the packing list! •... -
Page 15: Supply Connections
SUPPLY CONNECTIONS 13.1 HOSE CONNECTIONS W A R N I N G ! Aggressive condensate is possible. Wear protective glasses and proper protective clothing! The gas inlet and outlet connections are at the upper part of the heat exchanger. For possible connectors see technical data (see chapter 8). -
Page 16: Electrical Connections
In the standard configuration, the tubes for removal of condensate are connected directly to the heat exchangers. These protrude with the GL 25-12 tube connectors* (Duran glass heat exchanger) respectively with G 3/8“ * thread joint (PVDF or stainless steel heat exchanger) above the base plate of the cooler housing (Fig.2). Condensate removal is done by customer according to the type of operation with: - Automatic float-type condensate traps AD-... -

Page 20: Closing Down
CLOSING DOWN The location for the cooler must remain frost-free, even when the unit has been switched off! N O T E ! If the cooler unit is putting out of action for a short time no particular measures need to be taken. We recommended sweeping the cooler with inert gas or ambient air while the unit is putting out of action for a longer time. -
Page 21: Adding And Replacing The Heat Exchangers
• Pull out the box; • Remove the crossbars holding the filter element by pulling with moderate force in the direction of the filter element axis; • Remove and replace the filter elements. Reassembly is done in the reverse order. When using automatic condensate removal by means of peristaltic pumps, the hoses of the peristaltic pumps must be checked every three or six months, depending on the operating conditions, and replaced if necessary. -
