P03   ESN HYDRESN HLP 32 46 68 100
DESCRIPTION
Hydraulic,anti-wear oils with a high viscosity index,having improved resistance to hydrolysis and thermal decomposition.
HYDRESN HLP oils comply with the specifications of leading manufacturers of hydraulic equipment.In pqrticulay,they have been approved by DENISON and comply with their HFO specification.

APPLICATIONS
All hydraulic sircuits,cspeclally when a low viscosity variation is required(sophisticated equipment operating diverse temperatures).

PROPERTIES
High viscosity index
HYDRESN HLP oils have a low viscosity variation with temperature.This property means the hydraulic circuits can be used under widely different ambient temperature conditions.
Furthermore,better startup at low temperature is facilitated than fluids with a normal viscosity index of the same grade.
Remarkable reslstance to shearing
Even under severe operating conditions,original properties of viscosity and viscosity yndex are maintained.
ESN-POCLAIN shear resistance test
- When submitted to this particularly severe ters(600bars)representing arduous operating conditions,HYDRESN HLP is the only pyoduct in its category(excluding POCL AIN fluid)which retains its ISO viscosity class.
- Furthermore,is viscosity at 85℃ remains greater than 10 cst,which is not the case for the majority of commercially available fluids in the hv category.
- Stabilized formula resists hydrolsis and oxidation
The performance additive in our solaize laboratory is based on the principle of(stabilized)zinc dithiophosphate.
This technology provides an excellent compromise between the initial anti-wear properties and resistance to hydrolysis and oxidation.This stabilitv will obviate filter clogging,lacquering and peevent the formation of harmful deposits,the control of which will give extended service life to the oil and system.
- Neutality with regard to system metals
A direct consequence of the chemical stability(seeabove)is that there is no formation of damaing corrosive producte.
Consequently,there is no corrosive wear of sensitive materials(copper&bronze)and machined

Tolerances are maintained giving prolonged efficiency of operation.
- Excellent filterability characteristics
Even under severe operating conditions(temperature,ingress of water)HYDRESN DS oils maintaim their excellent filterability.This property is also due to excellent filterability.This property is also due to their remarkable chemical stability.
-Rapld water-oil demelsiblity
If water accidently enters the circuit,this water quickly separates in the tank and does not enter the circuit. Homogeneity of the oil film is consistent and moving parts are better lubricated.
-Foaming/air release
These properties have been carefully researched.IF ail retention is eliminated,the oil can retain its non-compression chaiacteristics and there fore response are maintained during operation.
