Working with your Varem RFQ
Varem's membrane autoclaves and expansion vessels act as a hydrodynamic buffer in pressurized water systems, reducing how often a pump needs to restart. Vessel category (I through IV, per the pressure equipment directive) and nominal volume/pressure rating are stamped on the unit and matter for compliance, not just fit — replacement membranes and pressure switches should be matched to those ratings rather than assumed from tank size alone.
Customers can send part numbers, maker references, equipment model data, serial numbers, nameplates, photos, drawings, old offers or previous supply documents. We review the information before quoting so the request is handled as a technical procurement task rather than a generic product search.

How to send a useful Varem RFQ
Attach the clearest technical information available. A single photo of a nameplate, an old offer line or a marked drawing can prevent delays when there are similar models, revisions or connection types.
If the item is obsolete or hard to identify, include dimensions, application notes and any alternative references already checked by your engineering team. We can review the request and reply by email with the next steps.
