SAG - Innovative solutions in thermal heat transfer

Thanks to several decades’ experience in heat-exchanger technology, SAG Industries has become a privileged partner of several large groups in sectors such as the chemical and petro-chemical industry, the pharmaceutical industry and the nuclear industry.

From engineering to the manufacture of new material, including reconditioning, the production of spare parts and the assembly of skid units, SAG Industries offers a complete range of services and products adapted to the thermal requirements and specifications of its customers.


SAG Pharma

SAG Pharma is a manufacturing unit dedicated exclusively to the pharmaceutical industry and fine chemistry sectors. It is a "clean" covered space of 1200 m², dedicated solely to the manufacture of white steel equipment (stainless steel alloys, hastelloys, incoloys, duplex alloys) and composite materials (polypropylene, PVDF, ECTFE, ETFE, and PTFE).

  • Aseptic heat exchangers
  • Aseptic recuperators
  • Stills colomn – clean steam generator
  • Heat exchangers for fine chemistry sector
  • Spare parts
  • Heat exchangers for food sector
  • Aseptic tank


All research phases (heat and mechanical design, production of drawings) are carried out in-house, which guarantees flexibility in execution and rapid action.


Specific features of SAG aseptic exchangers

Just as for the chemical or petrochemical sectors, aseptic (and also food and cosmetic) heat exchangers are conceived and designed based on an individual approach which enables SAG to respond to all of their clients' requirements.

Their engineers strive daily to improve the design of these double tubular plate exchangers in order to deliver an optimum heat and mechanical solution, while complying with pharmaceutical rules (FDA, GMP, cGMP, USP27, etc.).

The equipment may be positioned horizontally (with the possibility of being inclined) or vertically.

They are completely drainable and ventable.

 They are fitted with a double tubular plate system which enables leaks to be detected.

 The tube/tubular plate joins are produced using orbital welding for external plates and using double-groove hydraulic crimping for the internal plates (no damage to the condition of the surface compared to the traditional system).

 Their heads are machined "in bulk".

 These have leakage channels and flat embedded seals in order to ensure there are no areas of retention.
