Capacity Chart
The chart shows the maximum capacities for hotand cold condensate discharge at factory setting(steam-tight closure).
Curve 1Hot condensate capacities
Curve 2Cold condensate capacities
When ordering please state:
Steam pressure, steam temperature, backpressure, quantity of condensate to be dis-charged, connections, size, position of the trapand details of application.
The following test certificates can be issued onrequest, at extra cost:in accordance with EN 10204-3.1 A, 3.1 B and3.1 C.
All inspection requirements have to be statedwith the order. After supply of the equipment cer-tification cannot be established. For tests andinspection charges please consult us.
