Compressor overhaul
We are trained to overhaul screw compressors and reciprocating compressors and have experience with the following brands;
- Mayekawa
- GEA
- Bitzer
Service can be performed on site but we also have the means and tools to perform the job in our workshop.
Laser Alignment
We have the tools (SKF Laser Alignment) to align the motor to the compressor when required. This can be done after a motor or compressor replacement or when there is a suspicion of misalignment.
Heat exchanger inspection replacement and repair.
When Shell and Tube heat exchanger work with corrosive media like seawater and calcium chloride they can suffer from corrosion. In many cases this will eventually lead to a failure of the heat exchanger causing the cooling medium to enter the system.
Eddy Current Analyses
When requested we can inspect the heat exchanger on site with Eddy Current Analyses to check the wall thickness of the tubes. The report will show which tubes have reduced wall thickness after which we can advise which tubes should be replaced to prevent tube failure.
Replacement and repair
We can repair shell and tube heat exchangers or replace them when necessary. Additionally we can advise which materials are the best for the application.
Vibration
We have the tools to do a simple vibration test on the electrical motor and compressor of the refrigeration system. This will give a very good impression if the vibration limits are not exceeded. Excessive vibration can lead to serious damage of the compressor and the motor. When vibration levels are exceeded, the cause of the problem must be investigated and resolved.
Spare part deliveries
We can deliver and install spare and replacement parts for almost every refrigeration system or compressor.
Platefreezer plates
We design and produce replacement plates for platefreezers. We have delivered thousands of plates for brine systems and CO2 systems with improved heat transfer, strength and corrosion resistance.
Replacement of outdated control systems of refrigeration systems
A refrigeration systems and its components in general will always stay in operation for a much longer period than the control systems of the refrigeration plant.
The lifetime of industrial PLC and computer systems is in general 15 years after which it is difficult to buy spares and if they are available the price is very high.
We replace complete control systems together with the Human Machine Interface and rewrite the software. We will do the complete change and will prepare back plates for the original electricalsystems.
By-pass brine filters
We deliver by-pass brine filters that are installed in CaCl2 systems. The brine filter has four strong magnets inside that will collect steel particles from the system.
The filterhousing is made from stainless steel and is equipped with pressure gauges to monitor the pressure difference of the filter as dirt indication.
Air cooler replacement
We design and deliver custom made galvanized air coolers that can replace existing coolers that may need to be replaced due to cleaning of the coolers with cleaning agents that damage the galvanized layer of the tubes and the fins. Replacement coolers may be difficult to obtain when the original supplier does not produce the coolers anymore. We replaced coolers of blast freezers and whirlbed freezers. Dimensions are checked on site and we will deliver an air cooler that fits exactly.
