Commissioning
5.1
BOGE-Duotherm BPT
Proceed as follows during commissioning:
–
Check oil level in the oil circuit. If necessary, top up oil.
–
Slowly open the stop valves in the water supply and discharge line.
Avoid pressure hammers!
–
Maintenance
Vent the pipelines.
Lime, oxides as well as grease or oil will deposit in the ducts of the plate heat
exchanger during operation.
Regular cleaning will prevent thick deposits clogging individual ducts of the
plate heat exchanger.
Cleaning intervals
Excessively soiled and limy water:
6 months
Moderately soiled water, surface water:
1 year
Lightly soiled water:
3 years
Recommended cleaning agents
Grease or oil deposits:
Paraffin
Oxide or lime deposits:
formic acid, acetic acid or citric acid
Attention!
Always observe the instructions of the cleaning agent manufacturer!
Cleaning methods
Flushing:
–
First close all stop valves in the supply lines.
–
Close all stop valves in the discharge lines.
–
Wait until the plate heat exchanger has cooled down.
–
Open the flushing connections and drain the plate heat exchanger.
–
Flush the plate heat exchangers.
For this purpose, pump one of the above mentioned cleaning agents
through the plate heat exchangers for an extended period of time.
–
After flushing, rinse the plate heat exchanger thoroughly with water
(e.g. using a high pressure hose).
Enhance the cleaning action by the following measures:
–
Use a larger mass flow rate than for standard operation.
–
Flush the cleaning agent through the plate heat exchanger in opposite
direction to standard operation.
Allow to react (tenacious soiling):
