Inventor of the continuous vacuum pan, FIVES CAIL offers its Customers more than 30 years of experience in continuous crystallization.

The third generation of FIVES CAIL continuous vacuum pan profits of the long experience driving to excellent performances in term of productivity as well as exhaustion of the massecuite.

The specific geometry of the calandria enables a very high recirculation and ensures highest thermal heating coefficient. Horizontal tubes of the calandria give the latter a low sensitivity to encrustation enabling its use on high purity products such as refinery one.

The FIVES CAIL continuous vacuum pan is available in monobloc version (CCTW), in double version (CCTD) or in an evolutive version in CCTW as well as in CCTD. The CCTD version actually gets two distincts volumes of crystallization, either for facilitating cleaning procedures or for working with two different products in parallel. The evolutive version enables a future expansion (in area and volume) of about 40 to 45% of the initial capacity.

Designed from careful original research and operational experience the FS/TH continuous vacuum pan provides a high quality crystal massecuite production, simple control and a cost efficient method of continuous crystallization.

The FS/TH continuous vacuum pan is available as a single multi compartment unit or as a stacked unit for installation in confined floor areas or where long operating cycles and "on the run" cleaning is required. The unique cross section ensures superb circulation without the need for additional agitation. A vertical tube calandria and low hydrostatic head ensures high heat transfer rates.
