Special Reglass and Refurbish of Reactors

Pfaudler, in addition to its expertise in manufacturing and market  products and engineered solutions, has a core expertise in the area of services and aftermarket. 
Here is an example of a full refurbish operation held on some of equipment for a pharmaceutical application. 

Product Line: two Reactors, DIN CE type, with 16.000 liter capacity each
The Reactors were built in 1998 by Technoglass in Italy for a Poly-aluminium Chloride (PAC) plant application, and were fully operational until the end of 2010.  
The Reactors have been purchased by Pfaudler and resold as a second hand after a full refurbishing and upgrade to an important Italian Customer, for an intermediate pharmaceutical production (API).

The reactors have been completely reglassed, refurbished and qualified according to PED and ATEX regulations; 

  • All parts have been refurbished; 
  • A new gearbox and a new electrical motor have been installed.
  • The manhole cover in AISI 304L have been reglassed with a final surface finish of 0.6 micron
  • Davit arm for easy manhole opening made in AISI 304L with a final surface finish of 0.6 micron
  • All split flanges, bolts, nuts and clamps have been replaced with new ones in full stainless steel 

Finally, the reactors have been fully insulated, including the top head, using  an AISI 304L insulation (3mm) with polyurethane foam; the final surface finishing has resulted in  0.6 micron. 
The overhaul and final test have taken place at the manufacturing plant of San Donà di Piave (VE), in Italy. 
The photos are showing the state of the reactors before and after the servicing.
