Plate Cleaning
Chemical cleaning of plate packs at our works in Chennai. Plates leave the frame fouled. They go back clean, with the herringbone pattern and gasket groove clear.

- Scale, deposit and biofilm
- Gasket groove cleaned out
- Plates inspected before refit
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 clean plate packs at our Chennai works, on units we supplied and units we did not.
Our Clients
Plate Cleaning
Fouling blocks the channel between the plates. The duty falls and the pressure drop rises. The unit stops holding its outlet temperature. Cleaning the pack restores the channel. It does not repair a plate that is already pitted or cracked. The dye penetrant test finds those plates.
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 Plate Cleaning Works
The steps in order, from taking the unit apart to putting it back together.Pack stripped and recorded
We note the closing dimension. We take the plates off the carrying bar in order, so the pack goes back in the same sequence.
Chemical clean
We soak the plates in a cleaning solution chosen for the fouling. Scale, process deposit and biofilm each need a different chemistry. Agitation and soak time do the work. Wire brushing a plate face does not.
Rinsed, neutralised and dried
We rinse the cleaning solution off and dry the plates before inspection. Nothing is left behind to attack the plate or the new gasket.
Inspected plate by plate
We check each plate for pitting, cracking and distortion around the ports and gasket groove. We set aside any plate we would not put back, and show it to you.
Send Us the Unit Details
To quote plate cleaning we need:
- Make, model and plate count of the unit
- What the unit runs on both sides
- What the fouling looks like, or a photo of a plate
- Whether the pack is to be re-gasketed at the same time
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.
