Heat Exchange
Shell-and-tube and plate evaporators matched to refrigerant, approach and the fouling the fluid will actually carry.
Part of our Air-Cooled Condensers service line — we supply, install and maintain it, not just sell it.
The evaporator is where a refrigeration plant either makes its duty or quietly does not. Undersize it and the suction pressure sits low, the compressor runs longer than it should, and the running cost of that decision is paid every day for the life of the plant.
Selection is against refrigerant, approach temperature and fouling factor together. A clean-water duty and a process duty carrying solids need different tube velocities and different cleaning access, even at identical kilowatts.
We supply both shell-and-tube and plate types, and will say which one the duty actually wants — plates are compact and efficient until the fluid fouls them, at which point a shell that opens is worth more than the floor space it costs.
Representative units and components. Configuration, finish and connection sizes are built to the order — these show the range, not a fixed model.
Sizes, materials and duty are confirmed against your drawing and a site survey before quotation — nothing here is a fixed catalogue entry.

Applications
Options & accessories
Shell and tube exchangers built to duty — copper, cupro-nickel or stainless bundles in carbon or stainless shells, sized against the process rather than a catalogue rating and pressure tested before despatch.

Air-cooled condensers for sites where water is scarce or treatment is impractical. Coil face and fan selection are sized against Saudi summer ambient, not a temperate design day.

Dry coolers for closed-loop process and comfort cooling — heat rejected to ambient with no evaporative loss, no make-up water and no water treatment to maintain.
