Service Calculator

How long will your gaskets last?

Using Alfa Laval’s proprietary GPredict™ tool, our service advisors can give you a reliable estimate of the expected lifetime of your gaskets. The tool relies on precise calculations based on your specific equipment and relevant application details, including temperature, gasket material, whether you use glued or non-glued gaskets, and how often you open your unit in the course of annual operation. With that, you can plan the reconditioning of your plates, since you always know when it’s time for regasketing well in advance. Take advantage of GPredict™ with a customized gasket prediction based on your installation* by contacting us today or test our simplified version below.

Prediction of gasket lifetime

Gasket material: NBRP

NBRP is Alfa Laval’s unique nitrile performance grade for high temperatures

Max. operation temperature

This temperature range refers to 0-100°C (32-212°F).







Estimated number of openings per year








*GPredict™ estimates are valid only for clean water duties, or applications using other fluids that have no chemical impact on the gasket. Gasket lifetime predictions are not available for units that employ aggressive media.


Reconditioning and preventive maintenance

All heat exchangers lose performance over time. Alfa Laval's cleaning equipment (CIP) provide quick and easy in-line cleaning, but we recommend sending the units for recondition on a regular basis to reset the status of your equipment to an as-good-as-new condition. 

A Performance Audit by a qualified engineer gives you an assessment of your units' current state, which makes planning for downtime easy. At reconditioning we replace gaskets, upgrade plates or replace damaged ones with Alfa Laval genuine spare parts according to original specification. 

Visual Condition Assessment (VCA)

Thanks to our unmatched heat exchanger expertise, Alfa Laval can perform a visual inspection of your gasketed plate heat exchanger while it is in operation, identifying potential issues before they become major problems. Using infrared camera technology, we also evaluate the actual heat transfer performance of the heat exchanger. We then provide you with recommendations based on our findings and analysis of the thermal images.
