Gasketed plate
Most versatileCorrugated plates clamped between frame plates with gaskets. Capacity can be changed by adding plates, and the pack opens for cleaning.
Plate heat exchangers, serviced right.
Design, genuine spares, service and retrofit for any plate heat exchanger application, backed by two decades of hands-on experience. Serving customers across India.

About us
Two decades inside plate heat exchangers
RK Engineering & Services was founded by Ms. Rekha Rakesh Khairnar, a specialist in plate type heat exchanger design, spares and service.
Before starting the company, Rekha worked with three of the best-known names in the industry and learned the equipment from the inside: how it is designed, how it is built, and how it fails in the field.
Today we handle new projects, retrofit orders and after-sales service. Spares come from genuine sources and are assembled in our own workshop, so what reaches you has been handled by people who know the unit.

Plate heat exchanger types, makes & applications
From gasketed units to fully welded, we support the full range of plate heat exchanger types across every major make.
Semi-welded
Aggressive media, refrigerantsPlates welded into cassettes so the aggressive fluid never touches a gasket. Used on ammonia refrigeration and chemical duties.
Free-flow / wide-gap
Fibres, slurries, viscous fluidsWider channels with few contact points, so particles pass through. Used in pulp and paper, ethanol and process heat recovery.
Double-wall
Fluids that must never mixTwo plates per cassette with a leak path between them, for hazardous pairs of fluids where cross-contamination is unacceptable.
Brazed
Compact, gasket-freePlates permanently brazed into a sealed pack. Common in HVAC, heating and refrigeration, but the pack cannot be opened.
Fully welded
High temperature & pressureWelded seams replace gaskets for demanding chemical and process duties. Cleaned by chemical flushing, not by opening.

Shell & tube heat exchangers, every type
Beyond plate units, we handle shell and tube exchangers in all common configurations, including bundle and radiator type.
Fixed tubesheet
Simple, economicalTubes are fixed into tubesheets welded to the shell. Compact and cost-effective for clean shell-side fluids. The bundle stays in the shell.
U-tube
Handles thermal expansionTubes are bent into a U and held at one tubesheet, so they expand freely. The bundle can be pulled out for cleaning the outside of the tubes.
Floating head
Easy to clean, high dutyOne tubesheet floats inside the shell. Copes with large temperature differences, and the whole bundle can be removed to clean both sides.
Tube bundle
Replacement & retrofitThe tube bundle is the heart of the exchanger. Replacement and retrofit bundles can restore performance without replacing the entire shell.
Finned tube / radiator type
Air heating & coolingFinned tubes carry the hot or cold fluid while air flows across them, as in air heaters, air coolers and radiator type units.
Double pipe (hairpin)
High pressure, small dutyA pipe inside a pipe, joined by a U-bend. Suits high pressure and small duties, and sections are easy to add as the duty grows.

Frequently asked questions
What details should I send for a spares or service enquiry?
The make and model, the serial number from the nameplate, the number of plates, plate and gasket material if known, the fluids and operating temperatures, and a few photos of the unit. Even partial details are enough to start.
Where do I find the model and serial number?
On the metal nameplate fixed to the frame plate of the exchanger. Send us a clear photo of it and we can usually identify the unit.
How do I know my plate heat exchanger needs service?
Common signs are falling heat transfer performance, a rising pressure drop, leaks from the gasket edges or between plates, and mixing of the two fluids. Any of these means it is time for inspection.
Can you service any make and application?
Yes. We service any plate heat exchanger application, including ammonia, nitrogen and sulphuric acid. Please tell us the fluids so we can select the right plate and gasket materials.
Do you use genuine spares?
Yes. We buy spares from genuine sources and assemble them in our own workshop.
Can the capacity of my unit be increased?
On gasketed units, adding plates adds heat transfer surface, within the limits of the frame. Brazed and fully welded units cannot be opened, so they cannot be extended. Send us the details and we will assess.
What is the difference between gasketed, semi-welded and brazed units?
Gasketed units use gaskets and can be opened, cleaned and extended. Semi-welded units weld plate pairs so the aggressive fluid never touches a gasket. Brazed units are sealed and compact but cannot be opened. See the Products page for more.
Do you serve customers outside Gujarat?
Yes. We have customers across India and handle projects, retrofit orders and after-sales service.
