FLOWSiC® patented shell and tube heat exchanger
 USA patent Nr. US 6,904,959 B2 dated 14/06/2005
EUROPEAN patent Nr. EP1491842 B1 dated 18/06/2008
Shown is the SAURUS 939 vacuum pump manufactured by Italvacuum with capacity from 80 to 380 m3/h with vacuum values in a closed system of 0.66 mbar.
The main components of the unit are:
Double stage vacuum piston pump with the body in ductile iron and discharge valves in Hastelloy C22
FLOWSiC® silicon carbide post condenser
Hastelloy C22 solvent storage tank
Convoluted PTFE flexible hoses by proflex® with external spiral reinforcement together with SS braid
Italprotec has recently been awarded by Italvacuum an order for 6 FLOWSiC® silicon carbide post condensers with capacities of 0.35 m2, 1.35 m2 and 1.85 m2.
Acid fluid circulation occurs on the tube side where heads and compression tube sheets are manufactured in low temperature carbon steel lined with PFA.
Shell and main and secondary tube sheets are manufactured in AISI 304L.
The integrity of the seal on the silicon tubes is assured through use of the Italprotec design system consisting of triple tube sheets with two o-rings (Kalrez® and Viton®), together with one intermediate PTFE distance ring.
Hydrostatic testing is carried out with water at 25°C in accordance with the customer's technical specification as below:
Shell/cooling side: 18 bar – duration 10 minutes
Tubes/condensing side: 5 bar – duration 10 minutes
Silicon carbide heat-exchangers were specified in preference to Hastelloy C due to the many benefits offered by this superior material. Silicon carbide is lower priced and more cost effective with more efficient heat exchange characteristics. Many users have reported extended reliability using FLOWSiC® heat exchangers.
Another advantage of the FLOWSiC® exchanger is the absence of metallic leachants in the process fluid where contamination and high purity are of paramount importance.
Italprotec is pleased to announce that they have recently implemented Aspentech Tasc+ software technology for the design of its heat exchangers.
This latest generation of software allows detailed simulation with the following significant benefits:
Equipment cost savings
Reduced energy costs
Increased engineering efficiency
Solving process constraints
Solving dimensions constraints

Protef ® DN 350 dosing vessel PFA lined with DIN 7081 longitudinal sight glasses
 The PN6 50 lt. dosing vessel represented in the photo was made for an Italian customer related to 12 units suitable for vacuum conditions.
The thickness of the PFA lining is about 11 mm; the resistance to vacuum is ensured by the thickness itself and by different anchorages obtained directly on the carbon steel body. The weight for the only PFA lining of each tube, without head and bottom flanges, is about 15 Kg.
Absolute word wide news: today vessels, separators, and ancillary equipments lined with PFA can be realized with longitudinal sights according to norm DIN 7081 from DN 100 / 4” to DN 350 / 14” class PN 6, PN 10 or ANSI 150.
The 12 dosing vessels have been tested to our factory, with positive result, at 10 bar for 10 minutes according to norm PED 97/23/CE - Category II, module H.
