Plate type
Plate thermal exchanger is composed of multiple corrugated multiple electric heating panels hanging between the upper carrying bar and the underneath guide bar.
The electric heating panels make a hole enabling two fluids to be passed through, and the shape of the valley formed by the panels changes the flow of fluids into a turbulent flow and acts as a support to the plates against the input indifference between two fluids.

Bowman Marine Heat Exchangers.
There are three methods employed for water-cooled marine petrol and diesel engines: direct, heat exchanger and keel cooling. Direct cooling of the cylinders and heads by sea-water is unsatisfactory, because the engine - which was probably originally designed for radiator cooling - will run too cold and the sea-water will eventually ruin the cylinder block and heads.
Bowman Heat Exchangers are high-quality products incorporating both the best materials and the latest technical features.

Heat Exchangers
We make the different process:
- Built heat exchangers to replace the current system,
- Report to the customer on repairing or replacement, when we receive the damaged exchanger in the factory
- Repairing your products even when an in-situ repair is needed.

No chance of product intermixing
With Safetytherm you are always on the safe side. Our developers have created a perfect design that absolutely excludes the possibility of non-compatible products mixing with each other.
Read more here on the GEA Exoflex safety solution:
The Safetytherm double-wall plate heat exchanger by GEA Ecoflex consists of two extra-thin plates which form a small leakage gap. The inlet and outlet openings of the plates are welded. Apart from that, their design is the same as that of conventional gasketed plate heat exchangers.
In the case of a plate breakthrough, the product will not enter the neighbouring flow gap, but the leakage gap. The product is conveyed to the outside via special leakage channels without any product mixing being possible.
