CSH and CSVH: Connections for external oil coolers
CSH and CSVH compressors have designated connections for external oil coolers. The connection positions for
each compressor can be found in the BITZER SOFTWARE:
1. choose the compressor type
2. choose the tab "Dimensions" for dimensional drawings
3. choose the tab "Information" for the legend of connection positions
– CSH: Connections for external oil coolers on the rear compressor side, directly below the discharge gas shut-
off valve (oval or rectangular flange)
– CSVH: Position 11a and b shows the connections for external oil coolers
CSH: Connection adapter and additional oil injection
Connection adapter:
• CSH65.3 / CSH75.3: Replace oval flange by connection adapter with control valve (option). Connection diameter
16 mm - 5/8" each, kit no. 367 912 01
• CSH85.3 / CSH95.3: Remove rectangular flange and replace with connection adapter with control valve (option).
Connection diameter 22 mm - 7/8" each, kit no. 367 912 02
• Connection adapter without solenoid valve on request (if a former type is to be replaced by a CSH.3 without con-
verting the system).
Optional control valves are available, they are integrated in the connection adapter. The control valve opens an ad-
ditional oil injection nozzle and should be controlled by a thermostat so that it opens when oil cooling is required.
Observe the application limits (see BITZER SOFTWARE). Details see Operating instructions SB-170 .
