HEAT EXCHANGER RECONDITIONING
MAXIMUM EFFICIENCY MINIMUM COST
Over time, heat exchangers accumulate scaling, residues, and performance losses that compromise the proper functioning of the system.
La reconditioning is the ideal solution to restore your heat exchanger to its prestazioni originalireducing costs and extending its service life.
The reconditioning of a plate heat exchanger restores its original performance while reducing total operating costs.
- Extends the lifespan of the equipment and the connected system.
- Improves thermal efficiency.
- Minimizes energy consumption.
- Ensures production reliability.
- Reduces production costs.
ACTIVITIES
- Standard procedure (std cycle):
- Plate identification
- Determination of the residue to be removed
- Removal of the gasket, either clip/snap type or glued
Removal of the gasket, either clip/snap type or glued - High-pressure washing of all plates (300 Bar), with hot water and detergent if necessary
- Plate washing in acid bath / rinsing / alkaline bath / passivation
- High-pressure washing/rinsing up to max 600 Bar to stress the plates and highlight any cracks or holes
- Removal of the glued gasket
Can be performed with a flame if the adhesive is a polymerized two-component, or by heating in an oven at 150°C followed by mechanical extraction. - Removal of all gasket and adhesive residues from the plate grooves using rotating nylon or brass brushes, depending on the plate material. Final cleaning with a solvent such as MEK or acetone.
- Inspection of the plate and gasket grooves to detect any deformations, corrosion, or holes.
- Penetrant testing of all plates (Wood’s method with UVA lamp)
- Low-pressure washing to remove the penetrant liquids
- Drying in a ventilated oven
- Re-gasketing with clip/snap type or with single- or two-component adhesive
Vulcanization in oven if necessary - Final inspection, removal of excess adhesive
- Packing on pallet with side protection and plastic film/wooden crate
- Drafting of the final technical report
