PRODUCT DESCRIPTION
AMSOIL Synthetic HT Series High Temperature
Lubricating Oils are based on novel, proprietary technology,
creating an antiwear product which incorporates
the highest quality synthetic base fluids. HT Series
Oils provide high operational temperature ranges and
unbeatable thermal stability properties. The additive
chemistry used provides excellent friction-reducing characteristics,
and the synthetic base stocks are both thermally
and chemically stable, virtually eliminating carbon
formation in the recommended temperature ranges.
Typical problems with other high-temperature lubricants
such as thermal degradation (carbon formation),
poor volatility characteristics (excessive smoke and
fumes), and high oil consumption (from volatility and
over lubrication) can easily be overcome by using
AMSOIL HT Series High Temperature lubricants. The
ability of the HT Series oils to provide cost-effective and
problem-solving service means increased uptime and
savings on maintenance costs and product consumption.
PERFORMANCE FEATURES
• Superior film strength and antiwear protection at
high temperatures
• Exceptionally low volatility
• Intermittent service up to 260°C (500°F)
• Compatible with petroleum and synthetic lubricants
• Exceptional multifunctional lubricants
APPLICATION RECOMMENDATION
HT Series Oils are the primary recommendation for applications
such as stentors, dryers, heat setting machines,
tenter frames, oven conveyors and chains, or wherever
a lubricant with exceptional high-temperature properties
is required.
Recommended operational intermittent temperature
ranges are up to 500°F. AMSOIL HT Series Oils are
compatible with most seals, paints, petroleum oils and metals including bronze-type components. The HT Series
Oils can also be used for a variety of applications, such
as gears and bearings or anywhere an antiwear, hightemperature
lubricant is required.
The HT Series Oils may be applied to chains manually
or automatically. Relubrication is dependent on chain
design and length, method of lubrication and operating
conditions. For chains operating at temperatures exceeding
180°C (356°F), it is recommended the chain rails be
checked for extra lubrication.
Although these oils are stable at high temperatures, to
maintain the effective film of lubrication, the relubrication
intervals should be monitored and the system periodically
inspected for an adequate amount of oil on the components. When increasing the lubrication interval, the quantity
applied may be reduced. Pay close attention when
adjusting lubrication intervals and quantities applied. Consult manufacturer’s recommendations and adjust
accordingly. Improving service conditions can be made
cost-effective by improved relubrication intervals. Although
AMSOIL lubricants are compatible with mineral oil-based
lubricants, it is recommended for optimum performance
that the system be thoroughly inspected, drained and
cleaned, if warranted, prior to installing the products.
