Galden® HT PFPEHeat Transfer Fluids for Industrial 价格: No.HT55, HT70, HT80, HT110, HT135, HT170, HT200, HT230, HT270

Detailed

GALDEN®HT is a line of dielectric fluids with boiling points ranging from 55°C to 270°C. Their excellent dielectric properties, high chemical stability combined with their capacity to operate at very low as well as elevated temperatures make them the best Heat Transfer Fluids for the agressive conditions used in Semiconductor and Electronic Industry.

GALDEN® is cheaper than DI-Water!

The operating cost of DI-Water and DI-Water/Glycol systems is estimated to be more than twicethat of GALDEN systems.

• DI-Water and DI-Water/Glycol are characterized by narrow operating   temperature ranges:

DI-Water: 0°C – 100°C

DI-Water/Glycol: -20°C – 65°C.

• GALDEN fluids are characterized by a wide operating temperature   range.

• GALDEN fluids offer different grades to optimize performance.

• DI-Water and DI-Water/Glycol systems require maintenance control for   water resistivity and efficiency of de-ionization resins.

• GALDEN systems do not require resistivity monitoring and   de-ionization resins

• DI-Water and DI-Water/Glycol could lead to galvanic corrosion in presence   of dissimilar metals, there placement of corroded parts increases the   operation costs

• GALDEN systems are practically maintenance free and no corrosion problems   are encountered.

• DI-Water and DI-Water/Glycol tend to dissolve ions and become ionized   leading to damage due to short circuiting.

• GALDEN dielectric properties do not change with use, no short circuiting   risk.
