The oil/air cooler can be assembled in various positions,
while the vertical design should be preferred. Sufficient
fastening has to be assured.
Some motors have got covered holes which
serve for draining off condensed water
which may be generated.
Please use proper hydraulic hoses to connect the oil/air
cooler. These are connected on the discharge side of the
cooling element (see illustration 9).
Make sure that the connections and hoses
are adapted to the oil/air cooler with regard
to pressure, flow rate, temperature and
liquidity.
Illustration 9: Oil/air cooler; example: OPC200 to 1000
With the use in potentially explosive atmospheres only those hydraulic hoses which comply
with the specifications of the overall approval of the machine may be used.
Motor and pump are supplied by KTR ready for use. With the inspection of the ROTEX
®
coupling (see
KTR-N 40210) disassembly or assembly of the bellhousing has to be performed in accordance with
KTR-N 41010.
The maximum static operating pressure must not exceed the load of 26 bar during operation. With sizes OPC850
to OPC1000 the maximum static operating pressure is reduced to 21 bar.
!
With dynamic load maximum torque peaks of 14 bar must not be exceeded.
The maximum permissible temperature of the medium to be cooled must not 80 °C
(standard arrangement). Please consult with KTR for any higher temperatures.
The temperature of the ambiance and the medium to be cooled should not change rapidly.
Please note boiling and freezing point.
