HEES
HEES (Based on synthetic esters):
Synthetic esters can be produced
on the basis of renewable re-
sources and also based on mineral
oil. They are highly biologically
degradable and not hazardous to
water and meet Water hazard class
1. They have high resistance to ag-
ing and are not sensitive to extreme
operating temperatures.
HETG
Triglyceride based = plant-based
oils. These environmentally friendly
pressure fluids are highly biologi-
cally degradable and are not haz-
ardous to water as a rule. As op-
posed to mineral oils, they have a
lower aging resistance and can be
used under temperature loads only
in a limited way.
HLPD
Pressure fluid based on mineral oil
with active substances for increas-
ing corrosion protection, resistance
to aging and with additives with a
detergent effect.
IEC DIN EN 60204-1
Electric equipment of machines -
Part 1: General requirements. This
part of IEC 60204 is applicable to
electric, electronic and program-
mable electronic equipment and
systems for machines, which are
not carried by hand during opera-
tion and includes a group of ma-
chines that work together in a coor-
dinated manner. The equipment,
which is covered by this part of IEC
60204, begins at the location of the
power supply of the electric equip-
ment of the machine.
ISO 6743/4
The most used pressure fluids are
produced on the basis of mineral oil
with the respective additives. They
are also called hydraulic oils. The
requirements for these hydraulic
oils are specified in ISO 6743/4 with
the designations HL, HM and HV.
HL: with active substances for in-
creasing corrosion protection and
resistance to aging. They are used
at pressures of up to 200 bar and
meet the normal thermal loads. HM:
with active substances for increas-
ing corrosion protection, resistance
to aging and reduction of wear due
to scoring in mixed friction areas.
HV: with active substances for in-
creasing corrosion protection, resis-
tance to aging, reduction of wear
due to scoring in mixed friction ar-
eas and improvement in the viscos-
ity-temperature behavior.
