SWEP heat exchanger repair
SWEP heat exchanger repair covers brazed units, which are replaced rather than opened. Send the nameplate and what has happened, and a specialist who works on that type will come back to you. Coverage is UK wide.

Common SWEP heat exchanger problems
It has failed or is leaking
Fluids mixing, a leak at the unit, or one that will not hold pressure.
Emergency repair →Losing dutyPerformance has dropped
Higher pressure drop, a wider approach temperature, or a duty it no longer reaches.
Cleaning options →PlannedA service or shutdown is coming
Planned maintenance, an outage window, or a spare that needs to be ready.
Servicing options →UnsureNot sure what is wrong
Send the nameplate and what you have noticed. That is enough to get an answer.

SWEP heat exchanger repair runs into one fact immediately: SWEP builds brazed plate units, which are sealed blocks with no gaskets and no way to open the pack. A fouled unit can often be cleaned in place. A unit that has failed internally is replaced, because the fault cannot be reached.
- Brazed plate heat exchangers, sealed units with no gaskets
- Compact units on HVAC, heat pump, refrigeration and industrial duties
What can be arranged for SWEP units
- Chemical cleaning in place, while the unit is still sound
- Establishing whether the fault is the unit or the system around it
- Like for like replacement matched on duty, pressure, connections and size
- Removal and disposal of the failed unit
SWEP heat exchanger questions
Can a SWEP brazed unit be repaired?
No. The plates are brazed into a sealed block with no gaskets and no way to open the pack, so an internal failure cannot be reached. A failed brazed unit is replaced.
Can it be cleaned instead?
Yes, chemically, while the unit is still sound. That is worth doing when performance has dropped, and it is not a fix for a unit that has already failed internally.
Why did it fail?
Freezing, water hammer and thermal cycling are common causes on brazed units. If the cause is still present the replacement fails the same way, so it is worth establishing before fitting another.
