Oliterm SFG 32 – Food-grade synthetic thermal oil NSF HT-1

Oliterm SFG 32

7600090

Food-grade synthetic thermal fluid for heat transfer systems in the food and pharmaceutical industries, certified as HT-1 by NSF (incidental food contact).

Available in
  • 20 Litres
  • 200 Litres
  • 1.000 Litres
 

APPLICATIONS

OLITERM SFG 32 can be used in closed-circuit heat transfer systems with an application temperature range between -10°C and +300°C (oil mass temperature at the boiler outlet*).

(*) In order to achieve a long product life at the maximum application temperature, it is essential to keep the circuit completely closed, and an expansion tank with an inert atmosphere (nitrogen, etc.) is recommended. Regular analysis of the fluid is also recommended to assess its condition and that of the installation.

PROPERTIES AND ADVANTAGES

  • Excellent thermal and anti-rusting stability, keeping circuits free of deposits and preventing viscosity increase, thus ensuring an efficient heat transfer. Long fluid service life, reducing maintenance downtime and costs.

  • High thermal conductivity for faster heat dissipation.

  • Outstanding resistance to cracking, reducing the appearance of carbonaceous residues.

  • High specific heat.

  • Good fluidity at low temperatures, accelerating the start-up speed of the installation.
