Tough scale on the coil
The sediment reduced the area of heat exchange and reduced the effectiveness of the condenser.
Case study / Fish processing
Evapco. Performance without replacing the device.
The hard scale on the coil reduced heat exchange and increased the risk of production disruption. We performed chemical cleaning without dismantling and then set up a permanent system protection program.

- Permanent protection of circulation
Which required a decision.
Continuity of cooling.Safe decision.
Removing the visible deposit was not enough. We also had to assess the material, the type of scale and the conditions required to clean the system safely.
Heat exchange
Increasing system load
In order to maintain temperatures, the installation worked to an increasingly less favorable extent.
Risk of production
Worse cooling in the food plant increases the risk of disrupting the process.
Workflow
Clean surface.It was security.
The sequence of actions was important: first the diagnosis and safe chemical process, then the way that limits the return of sediment.
-
Inspection and analysis of water
We assessed the condition of the coil, the type of sediment and the parameters of the cooling water.
-
Testing and selection of the process
We have determined the treatment product, the contact time and the method of washing suitable for the installation material.
-
Chemical cleaning
The process removed sediment without dismantling the device and exposed heat exchange surfaces.
-
Programme for the following period
dosing and monitoring help to reduce conditions conducive to the scale redeposition.
What changed in the installation
We confirm the efficiency of the arrangement, not the appearance.
After cleaning we verify the operation of the system, the reaction of water parameters and whether the protection program is ready to work in variable load production.

What keeps the effect
Effect after cleaning.Permanent security.
Together with the team of the plant, we determine parameters, control points, and response methods before the sediment begins to reduce cooling again.
-
Water fit for installation
The selection of the programme takes into account the quality of make-up water, materials and condenser working conditions.
-
Cleaning without guessing
The chemical process precedes the assessment of sediment and risks, and after it we perform flushing and control of effect.
-
Surveillance in production
Constant monitoring allows you to adjust the program when the load changes or the operating season of the system.
Implementation FAQ
Before cleaning.What is to be determined?
Safe cleaning requires evaluation of the installation, not just the choice of the treatment product.
Does chemical cleaning always require the condenser to be dismantled?
Not always. The possibility of cleaning without dismantling depends on the construction of the installation, the type of sludge, materials and access to circulation. We assess each case before starting work.
How do you protect the system after scale removal?
After cleaning, we select the conditioning program and determine the range of water control. This reduces the conditions that favoured the formation of sediment before intervention.
Can the work be scheduled to minimize its impact on production?
Yes. The scope and schedule are determined after risk assessment and available service windows. In plants with continuous production, it is particularly important to stage and prepare the process in advance.
