Here at the heat exchanger company we supply genuine Alfa Laval gaskets and plates. Just as all plate heat exchangers are not created equal, neither are the replacement parts. Using lower cost, lower quality plates and gaskets can lead to decreased performance and increased costs. While two gaskets may look identical, there are many important differences, not obvious to the naked eye. There is a dimensional accuracy of the gasket copy, a major challenge when using rubber, which is naturally subject to thermal expansion. In addition, a genuine OEM gasket normally contains at least 50% polymer, whereas a cheaper copy may contain as little as 20%. Put simply, a cheaper gasket will age faster and lose its sealine efficiency more quickly. Genuine rubber gaskets ensure tighter seals, longer lifetime and more uptime for gasketed plate heat exchangers. Non-genuine gaskets may use the same nominal designations as genuine Alfa Laval gaskets, but their material properties differ. Don't be fooled by gaskets that are slightly thicker - thicker is not better. Incorrect thickness causes inaccurate tightening calculations, which may cause leakage and/or deformation and destruction of the complete plate pack. This has been experienced by customers who use non-OEM spare parts.
So if you have an Alfa Laval Plate heat exchanger and require genuine plates and gaskets, please get in touch and we can get you the best price and delivery time possible.
