We bring the tools, knowledge and personnel so you can get on with your day and leave the service to us.

“I wish we would have hired you from the start.”

We hear this all the time from customers that switch to Alfa Laval from another gasketed plate heat exchanger service provider. Why? Because we don’t rest until we know your problems are solved.

Other service providers only focus on fixing the immediate problem. With over 125 years of service experience, our team of advisors go beyond the quick fix and focus fixing your equipment for the long haul. This is why we want you to think of us as not just a heat exchanger manufacturer, but as The Plate Heat Exchanger Service Company you can count on.

Heat exchanger reconditioning and repair services

Two of the most common reasons for decreased efficiency in heat exchangers are old gaskets that cause external leakage and deposits such as scaling, which lower the heat transfer and eventually clog the channels. By reconditioning your heat exchanger, you can solve these problems.

At Alfa Laval’s well-equipped service centers, our experienced technicians remove gaskets and scaling with specialized tools and chemicals. This prevents corrosion and creates an ideal surface for re-gasketing – without you having to handle the chemicals or waste. In addition, we thoroughly examine your heat exchangers, correcting any sealing problems or deformities. These services ensure your equipment continues to deliver high efficiency and optimal performance.

Plate heat exchanger frame repair service includes inspection, refurbishment, replacement of connection linings, and replacement of bolts or other frame parts. While reconditioning plates must take place at one of our service centers, some frame repairs can be performed onsite.

Reconditioning procedure

Pre-cleaning inspection
Upon arriving at the service center, your heat exchanger plates are examined for major corrosion, erosion and deformities. Our technicians will determine whether the plates should be reconditioned or replaced. 

Gasket removal
We use an efficient, yet gentle, method to remove the gaskets using liquid nitrogen or caustic soda, which completely removes the gasket while leaving the groove intact, preventing plate damage. Some field methods of removing gaskets, including using propane torches or rotating wire brushes, can severely harm the plates.

Hydrojet cleaning
The heat exchanger plates are initially cleaned with water to remove residue.

Chemical cleaning
The plates are immersed in specially formulated chemical baths, whose concentration and temperature are carefully regulated for the gentle removal of deposits.

Crack and deformity detection
Each plate is sprayed with dye and then carefully inspected under UV light to find even the smallest defects.

We carefully regasket the plates using a strong, 2-part epoxy glue, which is far superior to the rubber based contact cement used by other service providers. 

Oven-cured gasketing
The plates are then placed in a curing skid and baked in an oven for 3-5 hours under compression.

Pressure testing
When the heat exchanger is reassembled, a full hydrostatic pressure test is performed to ensure there is no leakage. 

Reconditioning report
Finally, you'll receive a detailed heat exchanger service report, including the procedure documentation and recommendations based on your results.

Heat exchanger cleaning

With our cleaning services, process surfaces are restored to optimal condition, which lowers the maintenance costs and extends your equipment’s lifetime. Alfa Laval offers a range of Cleaning-In-Place (CIP) systems and cleaning agents, specially designed and formulated to remove deposit build-up effectively from heat transfer, separation and fresh water generator equipment.

We only use carefully developed and environmentally sound chemicals.

Performance Audits

A Performance Audit verifies your plate heat exchanger is performing according to design specifications and helps identify areas where performance can be improved. A Performance Audit is especially useful when service intervals are difficult to predict and optimize.

A Performance Audit includes:

  1. Data collection and measurement - a service engineer will visit your facility to visually inspect your units and to log data using a portable logger with four temperature gauges and a flow gauge. This process does not disrupt operations and usually takes about one hour per unit.

  2. Analysis of data - back at the office, the engineer runs the data through a thermal analysis software program that uses performance benchmarks for every Alfa Laval plate heat exchanger to derive your heat exchanger's optimal heat load.

  3. Audit report - you'll receive a report which will compare your heat exchanger's performance to benchmark performance and indicates if your plate heat exchanger requires service.

Plate heat exchanger integrity testing

Gasketed plate heat exchangers are durable and long-lasting. But after prolonged use, plates can develop microscopic cracks, and gaskets can show fatigue over time. Alfa Laval now offers a new preventative maintenance approach to help you avoid unscheduled or unexpected downtime. The integrity tester is non-intrusive, quickly identifies potential microscopic flaws before they become leaks, and reveals plate and gasket condition without opening the plate pack.

How to lower your maintenance cost on any brand of GPHE and maximize the value for your maintenance dollars

Concerns over climate change have driven the refrigeration industry to place more focus on natural refrigerants. CO2 is a natural refrigerant growing in popularity in our refrigeration systems, but it comes with the challenge of designing components rated for higher pressures. Join us to learn more about Alfa Laval’s Industrial Refrigeration heat exchangers for high pressure applications.
