3. Product description

The heating compact installations WPKI-HK E and WPKI-HKM E
are specifically designed for buffer cylinders SBP 200 E, SBP 400
E and SBP 700 E. In conjunction with the pipe set WPKI RB, they
offer heating contractors a clear and easy means of connecting
the heating system to the SBP E buffer cylinder.
The return ball valve contains a gravity brake to prevent unin-
tentional natural circulation. The gravity brake can be opened
manually by turning the handle approx. 45° to its end stop.
The compact heating installation WPKI-HK E is suitable for op-
erating a heating circuit without mixer.
The compact heating installation WPKI-HKM E is suitable for
operating a heating circuit with mixer. The standard delivery
includes a 3-way mixer with servomotor.

A bypass can be used to reduce the flow temperature by mix-
ing in return water. The bypass can be infinitely adjusted with
the adjusting screw. For that, undo locking screw approx. 1
mm. Tighten the locking screw again after completing the
