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.

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.

Frequently 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.
