Your trusted plate heat exchanger service provider
You can trust Alfa Laval technicians to repair and recondition your gasketed plate heat exchangers – no matter the brand.
The heat exchanger plates are initially cleaned with water to remove residue.
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.
The plates are then placed in a curing skid and baked in an oven for 3-5 hours under compression.
Plate heat exchanger spare parts
Alfa Laval maintains an extensive inventory of spare parts for your plate heat exchangers.
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:
- 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.
- 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.
- 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.
Alfa Laval Service Agreements are tailor-made service solutions that combine any of our services, based on your specific needs. To maximise your performance and reduce your operating costs, these agreements bring you peace of mind by minimising the risk of unexpected breakdowns. They also give you full control over your maintenance budget.
