Shell Irus Fluids DU
High performance less flammable hydraulic fluids
Shell Irus Fluids DU are advanced, synthetic, anhydrous less flammable hydraulic
fluids based on organic esters and proven additives. These ISO Class HFDU fluids
are specially designed to provide good performance in conventional hydraulic
systems and have better fire resistance than mineral oils. They are also
biodegradable with a low ecotoxicity, and are particularly suited for use in
environmentally sensitive areas.
Applications
• Typical applications for Irus DU are to be
found in the tunnel boring, metal, mining and
glass industries. Irus Fluids can replace
mineral oils in hydraulic installations to
provide good lubrication and a higher degree
of fire resistance.
Performance Features and Benefits
• Lower flammability than mineral oils.
• Readily biodegradable - biodegraded by >60%
after 28 days when tested in OECD 301 B (CO2
evolution test).
• Low ecotoxicity - ‘not harmful’ to plants (algae),
invertebrates (Daphnia sp.) and fish; EL50/LL50
>100 mg/l when tested as water-accommodated
fractions in OECD 201, OECD 202 and OECD
203.
• Excellent viscosity/temperature characteristics -
minimum change of viscosity with variation in
operating temperature, giving true ‘multigrade’
characteristics.
• Pump anti-wear protection similar to mineral
hydraulic oils.
• Low flammability maintained during the life of the
fluid.
• Excellent corrosion protection.
• Compatible with most materials specified for use
with mineral oils.
Specification and Approvals
Irus DU meets the requirements of:
Classification HFDU according to ISO 6743-4
ISO 12922 Specifications for fire-resistant
hydraulic fluids - category HFDU
The European Communities Mines Safety
Commission 7th Report - Requirements for
less flammable fluids ('7th Luxembourg
Report').
Irus Fluid DU is approved by:
Eaton for Industrial and mobile hydraulic
systems according to Brochure 694
requirements.
Change-over Procedure
In order to achieve maximum benefits from the
use of Irus DU, it is necessary to completely drain
all mineral oil from the hydraulic circuit prior to
filling with fresh fluid. A detailed change-over
procedure can be obtained from your Shell
representative.
Storage
Drums must be kept sealed in weatherproof
conditions, in order to prevent contamination by
water or dust.
Seal Compatibility
Irus DU are compatible with seal and paint
materials normally specified for use with mineral
oils, except those made from natural rubber.
More details are given in the attached "Typical
Physical Characteristics" table.

Health and Safety
Guidance on Health and Safety are available on
the appropriate Material Safety Data Sheet which
can be obtained from your Shell representative.
Protect the environment
Take used oil to an authorised collection point. Do
not discharge into drains, soil or water. |
