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 unintentional 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 Eis suitable for operating 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.
Standard delivery
The WPKI-HK E and the WPKI-HKM E are factory-sealed and comprise:
– high efficiency circulation pump ON 25, height 180 mm with 2 m connecting
cable
– tow-way ball valve with manual gravity brake in the return, complete with
handle
– tow-way ball valve in the flow, complete with handle
– two thermometers, 0 63 mm, display range 0-120 °C (red or blue facia ring
for identifying the flow and return)
– pump ball valve with flange and 1 ½” male (only WPKI-HK E)
– three-way mixer with variable bypass (only WPKI-HKM E)
– return pipe
– EPP insulation
– 2 fixing screws with washers and rawl plugs (in the pack)
Further accessories
– WPKI-HKV
The distributor, with 2 connection pairs respectively to the top and bottom,
is designed for the connection of two heating circuits in conjunction with the
heatixng compact installations WPKI-HK E and WPKI-HKM E.
Settings
WPKI-HKM E
3-waymixer
A bypass can be used to reduce the flow temperature by mixing 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 adjustment. The mixer is regulated via the servomotor. In the delivered
condition, both mixer and bypass are closed, and the locking screw is tight.
- Adjusting screw
- Locking screw
Servomotor
The angle of rotation is electrically limited to 90°. Upon reaching its end
stops, the drive will be switched off and switched to zero volt. The
servomotor can be switched to manual control via the rotary selector on the
casing.
