The Anatomy of a
Plate Heat Exchanger
Plate Pack
A stack of thin pressed stainless or titanium plates, clamped together with hot and cold fluid running through alternating channels. Every plate acts as heat exchange surface on both faces.
Drag to rotate
For representation purposes only.
Built to
Solve
Engineered against the specific failures that cost operators downtime, contamination or wasted energy.
Asset protection
Hard-worked plate packs fail through gasket ageing and plate fatigue — undetected, a single cracked plate cross-contaminates the whole circuit. Regular regasketing catches this before it becomes a process incident.
Process integrity
Wrong plate material or gasket elastomer for the fluid means early failure; correct selection is chemistry, not catalogue shopping. The same duty in two different fluids can call for two completely different plate packs.
Operational efficiency
Close temperature approaches (down to 1°C) recover heat that shell & tube geometry physically cannot — wasted approach is wasted energy, paid for every hour the plant runs.
Why Dolphin Group for
Plate Heat Exchangers
Multi-brand service capability
We regasket and recondition all major plate exchanger brands with UAE-held stock — no waiting on overseas OEM service slots.
Engineering-led selection
Every unit is thermally rated against your actual duty and fluid chemistry, not picked from a catalogue table.
Local+ and ADNOC approval
Procurement-ready for the world’s most demanding operators, with 40+ years of service behind every recommendation.
Key
Benefits
What sets plate heat exchangers from Dolphin Group apart, in specific and measurable terms.
- 1
Higher heat exchange rates
Three to five times the heat exchange coefficient of shell & tube in the same duty, so less surface area does the same job.
- 2
Close temperature approach
Down to 1°C for maximum heat recovery — recovering heat a wider approach would simply reject.
- 3
Compact footprint
Up to 80% smaller footprint and lighter installed weight, easing structural loading and plot-plan constraints.
- 4
Expandable in-frame
Capacity expandable by adding plates — no replacement capex when duty grows.
- 5
UAE-held stock
Plate and gasket stock for major brands cuts service downtime to days instead of weeks on back order.
- 6
In-country service
Full regasketing, plate cleaning and integrity testing carried out in-country, start to finish.

View SectorFrequently Asked Questions
When footprint, close temperature approach, or heat recovery economics dominate, and design conditions stay within roughly 25 bar and 180°C with reasonably clean fluids.
Yes — we regasket, clean and crack-test all major brands, with plate and gasket stock held in the UAE.
Typically every 5–7 years in moderate service, sooner at high temperature. Hardened, compressed gaskets that leak on restart are the classic sign.
Usually yes — frames are commonly sized with spare capacity, so plates can be added without replacing the frame.
Titanium is the standard for seawater duty; SS316 fails on chlorides at Gulf temperatures.
Dye-penetrant testing of the opened pack, or on-line by monitoring cross-contamination; we provide both workshop and site testing.
Yes — FDA-compliant elastomers for pasteurisers and food processing duties are standard scope.
