The operator knows the problem: Frequently on larger gasketed plate heat exchangers (PHE) with a large number of plates, displacements of the individual plates, in the clamped state, occur in the frame. This is intensified with every opening and closing of the plate heat exchanger and ultimately leads to leaks and mechanical damage to the individual plates.
The cause lies in the suspension area of the respective plate, which is sometimes too „weakly“ dimensioned. It serves to guide and fix the individual plate in the area of the upper and lower support rod. Once damage has occurred here, the displacements increase exponentially with each new closing of the plate package!
In the past, a completely new plate package was then ordered and installed for replacement, which usually involved long delivery times and high procurement costs. Due to the ever increasing shortage of raw materials, especially in the stainless steel and titanium sector, spare parts prices have increased many times over and the associated delivery times can be over a year, which would lead to escalation in individual cases!
This is exactly where IS-Service can offer you a patented solution with long-term reliability for your deformed plates.
