EGK 2-19 (+) 4 Installation and connection 4.1 Installation site requirements The unit is only intended for use in enclosed areas in a 19” rack or wall-mounted. Adequate protection from the weather must be provided when used outdoors. Install the unit leaving enough room below the cooler to discharge the condensate. Leave room above for the gas supply. -
Page 11: Connecting The Heat Exchanger
EGK 2-19 (+) 4.2.2 Connecting the heat exchanger The picture on the left shows the schematics for connecting two separate heat exchangers. To minimise gas wash out in the cooler, the two (identical) heat exchangers must be operated in series (right picture). This should be done as follows: Gas inlet line to red gas inlet on heat exchanger 2 (pre-cooling). -
