7.2 Lines and Pipelines 7.2
Connect the customer-supplied supply and drain lines according to the information in the
dimensioned drawing. Steam, condensate, compressed air and water must be equipped with
stop valves. Follow DIN 1988 when connecting the water. To avoid transmission of
structure-borne noise, you can connect the pipelines with a spacer of flexible metal
tubing and insulate the pipe holders.
7.2.1 Steam
Install the wiring system and connections in such a way that they are insulated.
Operating pressure 4 - 5 bar (58 - 72.5 psi) saturated steam.
If the admission pressure is more than 5 bar (72.5 psi), build in a reducing valve with
pressure gauge and safety valve.
The steam pressure reducer on the distillation system is adjusted to 3.0 bar (43.5 psi)
Peak steam demand (large steam generator):
M21, M26, M30
Drying
0.6 kg/min (1.3 lb/min)
Distillation 0.6 kg/min (1.3 lb/min)
1 = Reducing valve
2 = Vacuum breaker
3 = Descending slope
4 = Steam trap
5 = Stop valve
6 = Non-return valve
7 = Drain
8 = Customer side

7.2.2 Condensate
Install condensate line so that it slopes away from the machine, if possible. If there is an
ascending slope, provide a non-return valve and drain at the lowest point.
Attention:
Condensate counter-pressure must be at least 1.5 bar (21.8 psi) under the incoming
steam pressure.
