Houghto-Safe 620
Premium Grade Fire Resistant Hydraulic Fluid (Type HFC - Water Glycol)
Houghto-Safe 620 hydraulic fluid combines top quality system performance with the
high fire resistance essential for equipment operating in hazardous environments.
Benefits
* Excellent security against fire and explosion
* High lubricity and anti-wear characteristics
* Reliable system protection
* Long term stability
Application Profile
A fire hazard exists wherever hydraulic equipment operates near flames, hot surfaces or molten metals.
Accidental escapes of oil based hydraulic fluids on to such ignition sources have frequently caused fires or
explosions, resulting in death or injury to personnel, damage to plant and property, and expensive loss of
production.
Houghto-Safe 620 greatly reduces fire risk without compromising the reliability and high performance of
critical hydraulic system components. It is ideal for applications such as pressure die-casting machinery,
cranes, fork-lift trucks, ingot manipulators, glass and polymer forming equipment, presses, oven opening and
furnace tilting mechanisms, and many more.
