Problems and Solutions / Exchanger for Heating or Cooling Circuit

I- Problem and Solution:

"Can not get enough temperature radiators or fan-coils."

- Make sure that connection of heat exchanger is true.
- Make sure that sending hot water or steam from boiler to heat exchanger.
- Make sure cooling heat exchanger group has sufficient amount and degree of water.
- It could be air tightness because both of each sides of system running closed loop, make sure that there is running airventing system on the highest point of the system.
- If you have 3-way or 3-way proportional valve on the heat exchangers hot water supply line make sure that valves directs hot water to heat exchanger.
- Turn off the other valves on the collector, if hot water line feeding from collector to feed heat exchanger and then direct the water to heat exchanger.
- Make sure the pomps is working and suppliying enough flow rate.

II- Problem and Solution:

"Heat exchanger leaking out water"

- Control the tighteening measure of between two outer body of the heat exchanger is not more than desciribted at front sticker. If there is differences , bring to a minimum distance between two body.

III- Problem and Solution:

"Heat exchanger is not working as performed as first day"

- Due to the contamination, heat exchanger installation may have been collected and blokaged caused by dirt. Heat exchanger must be dissembled and must cleaned.
- Strainer in pipping may be clogged. Make sure the strainer is clean.
- Make sure that is there any change on capacity of pomps.
- Control that is condensate tank lower than the lowest point of heat exchanger. if not, please revise in this manner.
- Make sure that is the steams pressure which comes from steam installation has a higher value then technical detail which reported.

IV- Problem and Solution:

"Heat exchanger leaking out water"

- Control the tighteening measure of between two outer body of the heat exchanger is not more than described at front sticker. If there is differences , bring to a minimum distance between two body.

V- Problem and Solution:

"The two fluid passing through heat exchanger is mixing"

- One or more plates may be drilled. Mixing problem is not about gaskets.
- Turn off all input and output valves of heat exchanger. Contact with service department.
