"Full Service Package" is a maintenance service provided by HISAKA.
Skillful technicians who are familiar with design know how to take care of the heat exchanger and maintain it. Your heat exchanger will be returned to you with as new unit.

Your heat exchanger will be returned to you with the frame looking as good as new. -
[Before cleaning]
[After cleaning]
- Peace of Mind
- If plate penetration is discovered during the final test of the Full Service Package, a PT inspection is performed to determine the point of penetration and to estimate its cause.
Also, the manufacturer keeps parts in inventory to ensure the shortest possible restoration time. -
- Fast
- Your heat exchanger is cleaned, tested, and returned in standard 7 days after full service package.
Full Service Package Workflow
Degreasing tank / cleaning
After pre-cleaning, the heat transfer plates are placed in a chemical solution to remove the oils and unwanted material.
Plate gaskets that have been attached with adhesive are peeled off. The adhesive will be removed so the parts can be cleaned.
Jet cleaning
Stubborn dirt that could not be completely removed by immersion cleaning is removed by jet cleaning.
Completion inspection
After the heat transfer plates are cleaned, and gaskets are attached, the plates are then assembled on the frame, tightened to the specified dimensions, and then conduct a pressure resistance test.
Heat exchanger is checked to ensure no leakage before shipping.
Full Service Package Menu
For plate heat exchangers, HISAKA provides an optimal maintenance menu based on the know-how we have accumulated over many years.
? Full Service Package for Main Unit
Comprehensive maintenance service for customer’s plate heat exchanger.
The manufacturer disassembles, inspects, cleans the heat exchanger, and repairs and assembles the frame, so all you have to do is send it to us and it will be returned to you as new unit.
Full Service Package includes repair and repainting not only the heat transfer plates, but also the frame components.
Repainting not only improves the appearance, but also suppresses the progress of rust, so you can use the plate heat exchanger longer.
? Full Service Package for Plates
Depending on the installation location, it might be difficult to move or carry out the main unit.
If so, you can remove the heat transfer plates from the frame and send only them to us.
Your heat transfer plates will receive the same inspection and cleaning as the "Full Service Package for Main Unit." Then, before your heat transfer plates are returned to you, they are tested on our test frame to confirm the soundness of plates.
Other Maintenance Services
We also send our service engineers to customers who find it difficult to use the Full Service Package due to time and/or space constraints.
? On-site maintenance
We send our well trained service engineers to your site.
This is convenient for customers who have lack manpower to perform plate cleaning on site or never clean the plate heat exchanger before
Dedicated maintenance tools such as automatic tightening machines and hot water jets are used to perform this work.
Automatic tightening machine
Uniform tightening is required when assembling a plate heat exchanger.
Using an automatic tightening machine allows ideal tightening to be achieved in a short time, without the need for any special skills.
? Cleaning in place (CIP)
Cleaning in place (CIP) of a PHE makes it possible to remove stubborn scale and interior contaminants and to return performance to nearly the same level as new. However, if disassembly cleaning is not possible, HISAKA also provides cleaning in place (CIP) services. We provide a cleaning service with our "Plate-Clean" product dedicated for plate heat exchangers at our customers' sites.
Also, using "Plate-Clean" to perform circulation cleaning can wash away or dissolve and remove scales before stubborn stains are formed. This recovers performance and is effective for extending the disassembly cycle of plate heat exchangers.
