PHE Servicing
Full overhaul of a gasketed unit. We clean and test the plates, re-gasket the pack, and refurbish the frame by sandblasting, painting and zinc plating. Then we rebuild the unit.

- Clean, test, re-gasket, rebuild

About Us
Since 2016, CJP has supplied, manufactured and serviced plate heat exchangers for industry and OEMs across India. From our Chennai works we make gasketed units, cooling tower fills and replacement plates and gaskets, and our crews install and service them.
We overhaul gasketed units end to end, and service every brand we supply spares for.
Our Clients























PHE Servicing
Servicing combines the other jobs on this site into one. The pack comes out. We clean the plates, dye penetrant test them and replace the gaskets. While the plates are on the bench, the frame is sandblasted, painted and zinc plated. The unit goes back together closed to its nameplate dimension.
Tell us the make, model and plate count of the unit, and what it runs on. We quote against the job, not a price list.
How PHE Servicing Works
The steps in order, from taking the unit apart to putting it back together.Unit stripped and recorded
We record the closing dimension, plate count and plate order before anything comes off the carrying bar. We can then rebuild the pack exactly as it was, unless you ask us to change it.
Plates cleaned, tested and re-gasketed
The pack goes through chemical cleaning, dye penetrant testing and re-gasketing. Plates that fail the test are set aside. We show them to you before the rebuild.
Frame sandblasted, painted and zinc plated
While the plates are on the bench, we sandblast the frame, carrying bar and covers back to clean metal. Then we paint and zinc plate them. The unit returns to service with the corrosion removed, not painted over.
Rebuilt and closed
We hang the plates back in order, pull the tie bolts down in sequence and close the frame to the nameplate dimension. We check the unit before it leaves.
Packed and returned
We pack serviced plate packs and frame parts for transport, so they go back as they left our works.
Send Us the Unit Details

- Whether the frame is to be refurbished as well as the pack
Workshop & Site
We clean plates, run dye penetrant tests, re-gasket and refurbish frames at our works in Chennai. We install units and service them on site at your plant. Units that come to us go back packed for transport.
We service every brand we supply spares for. Alfa Laval, GEA & Kelvion, Sondex and Tranter plate packs all go through the same cleaning, testing and re-gasketing line.
Turnaround depends on the plate count. It also depends on whether we refurbish the frame with the pack. We confirm the date once we have seen the unit, and again with the order acknowledgement.

Frequently Asked Questions
01Will you service a unit you did not supply?
Yes. Most units that come to us were bought from someone else. We service Alfa Laval, GEA & Kelvion, Sondex and Tranter units, and the gasketed units we build ourselves. We hold the plates and gaskets for them.
02Is the work done at our plant or at your works?
We install units and service them on site at your plant. We do plate cleaning, dye penetrant testing, re-gasketing and frame refurbishment at our works in Chennai. The cleaning line and the blast booth are there.
03How long will our unit be out of service?
It depends on the plate count. It also depends on whether we refurbish the frame with the pack. We confirm the date once we have seen the unit, and again with the order acknowledgement. You can then plan the shutdown.
04What happens if some plates fail the DP test?
We set them aside and show you the result before we rebuild anything. You decide: replace the failed plates, replace the full pack, or replace the unit. We quote all three. We do not proceed until you choose.
05Do you collect and return the unit?
We pack serviced units and plate packs carefully before they go back, so nothing is damaged in transit. Tell us where the unit is. We quote collection and delivery with the rest of the job.
06How often should a plate heat exchanger be opened and cleaned?
It depends on the duty and the water. Common signs are a falling outlet temperature, a rising pressure drop across the unit, or a leak at the plate pack. If you see any of these, send us the readings. We tell you what the unit likely needs.
