AlfaVap

A bit more in detail 

AlfaVap is a semi-welded heat exchanger, i.e. a plate pack has gasket sealed cassettes of two plates that are welded together. The fluid is concentrated in the gasketed channel while the steam passes through the welded channel. These units are ideal for when two media have a very small temperature difference as it allows for use of a lower grade steam. In most cases this means cutting energy costs.  

The plate pattern generating high turbulence over the whole plate is specifically designed to optimize evaporation. This maximizes the heat transfer efficiency while minimizing fouling and scaling.  

Due to the plate-and-frame design with tightening bolts and pressure plate rollers, AlfaVap is easily accessible for inspection and mechanical cleaning. A low hold-up volume allows for using only a small amount of cleaning chemicals when running a cleaning-in-Place (CIP) procedure. 

The design is made for easy adjustment to changed capacity needs and plate cassettes can easily be added or removed to the existing frame. The flexibility is a major advantage over shell-and-tube units not allowing for capacity adaptations after installation.  

AlfaVap means trouble-free maintenance and a long service life. Glue-free clip on gaskets, pressure plate holder, bearing boxes and the Five-point alignment system makes opening and closing easy, quick and very safe – both in terms of not damaging the plate pack, but also for the personnel.
