The desalination sector in the Kingdom supplies parts no single size covers: pressure vessels, housings, exchangers and support frames, differing in weight and shape inside one project.
A desalination plant coating booth is built around the heaviest and most awkward part to handle, not around the average of what passes through.
Weight and load points first
Part size, weight and handling method are the first inputs in industrial finishing, and a chamber bought before they are fixed becomes a constraint on production rather than a step within it.
The delivered range runs from 3000 to 24,000 mm long, 3000 to 20,000 mm wide and 2650 to 6000 mm high, with the final figure coming from your largest part.
| Input | What follows from it |
|---|---|
| Heaviest part weight and lifting points | Hanging or conveying system inside the chamber |
| Largest part dimensions | Internal size plus the technician’s working space |
| Coating material | Heat curve and filter class |
| Shape — cylindrical or flat | Extraction direction, downdraft or side |
| Shifts per day | Durability criterion and maintenance schedule |
Cylindrical form and the air path
A pressure vessel or a recessed exchanger differs from a flat panel: the curved surface needs reach from more than one direction, and shadowed regions do not receive the same flow if extraction runs one way only.
Extraction direction is therefore set by the nature of the work and the part rather than by automotive convention.
Thermal mass and cycle time
A heavy metal part absorbs heat slowly and releases it slowly, so time to cure temperature is longer than for a sheet part of the same surface area. That enters both cycle time and required heat output.
Published heat output runs from 200,000 to 600,000 kcal/h, with electrical power from 11 to 50 kW on 380 V three-phase supply.
Controlled environment where the material calls for it
Some coatings in this sector are applied inside an operating window their supplier defines. Temperature and humidity control together is delivered on custom builds whose coating requires a controlled environment, set per project from the material and the part.
Frequently asked questions
What is the largest part you can take?
The published range extends to 24,000 mm long, 20,000 mm wide and 6000 mm high. Final size is built on the largest part in your project plus the technician’s working space.
Does the specification include the handling system?
Provision for hanging or moving parts inside the cabin is part of the design and is discussed with the specification. Its detail is built on your part weight and load points, and scope is defined in the technical offer.
Can humidity be held if the coating requires it?
Yes, on custom builds. Send your material datasheet so the operating window is read from it and the configuration built on that, rather than carrying a figure over from another project.
Which regulatory requirements apply?
Ventilation and fire requirements for finishing areas, disposal of solvent waste under the applicable environmental rules, and SASO conformity for imported equipment.
