• The flow of refrigerant sucked in from the evaporator is led over the engine and provides for a
particularly intensive cooling. Thus the engine can be kept special during high load on a relatively
low temperature level.
• Oil pump independent of direction of rotation for reliable and safe oil supply
• One pressure relief valve each on the low and high pressure side, which vent into the
atmosphere when these inadmissibly high printing pressures are reached.
