Gasketed

Standard Gasketed Plate Heat Exchanger

The workhorse for clean-duty heating and cooling.

Gasketed plate packs clamped in a frame, fully openable for inspection and cleaning, and expandable by adding plates. The default choice wherever both media are reasonably clean and duty pressures are moderate.

Pressed stainless plates stacked face to face, the chevron field running down into the port shoulders — Pressed plates stacked before the gaskets go on. The chevron field is what holds the channel open and turns the flow; where two plates meet, the opposing chevrons cross and make the contact points that carry the pressure.

Gasketed units on their frames, built and waiting for despatch. The painted carbon-steel frame is what a gasketed plate heat exchanger normally looks like; the plate pack between the tie bars is stainless, and it is the pack, not the frame, that touches the process.
A plate with its gasket fitted. The gasket rings the top-left and bottom-right ports out of this channel and sweeps around the other two, so the fluid enters at one corner and leaves at the diagonally opposite one, which makes it a diagonal-flow plate. The next plate in the pack carries the mirror of this gasket, which is what puts the other fluid in the channel behind it.
A gasketed unit closed on its frame: four flanged ports through the head plate, tie bars tensioned to the plate-pack dimension, and the plate pack visible along the side.
A plate with its gasket fitted, close. The gasket runs the perimeter and loops around the ports it seals out of this channel, and the chevron field it sits against is what holds the channel open.
The same unit packed for despatch. The frame is broken down and banded to the pallet with the plate pack between the plates, the threaded tie bars sleeved in red so the threads survive the journey, timber at every corner the strapping crosses, and the fastener bag taped on top where it cannot go missing.

Two-panel line diagram. Left: one pressed plate seen face on, with four corner ports, a chevron pressing and the gasket path, which rings two diagonally opposite ports out of the channel. Right: a section through the plate pack showing alternating hot and cold channels separated by single plates, the two media running in opposite directions, and the hot header gasketed shut at every cold channel. — What the gasket does, and why the channels alternate. Drawn here as a diagonal-flow plate; parallel-flow plates seal the two ports on one side instead, as the photograph above shows. Either way the gasket is the part that decides which channel a fluid enters, which is why compound and profile matter as much as the plate itself.

Chosen for

Clean liquid-to-liquid duties
Frequent inspection or mechanical cleaning
Capacity that may need to grow later
Exotic plate materials for corrosive media

Every heat exchanger we supply is hydraulically tested before despatch, both circuits under pressure together at the test pressures stated on its data sheet. The unit passes only if it holds that pressure without a drop, which is what demonstrates the whole assembly is leak-tight.

The circuits are also tested against each other, one pressurised and the other watched, so a leak between the two media would show. A copy of the test certificate is available on request.
