To develop a glycol-free fire-resistant HFC hydraulic fluid with
equivalent or superior functional performance compared to
traditional water-glycol based formulations, and improving disposal
of the exhausted fluid and environmental safety
ECOSAFE PLUS is a fire-resistant biodegradable hydraulic fluid (type HFC and viscosity grade ISO 46).
Its innovative formulation is based on a mixture of polymers and biopolymers, and it is glycol-free. Compared to traditional water/glycol based
HFC hydraulic fluid, ECOSAFE PLUS allows for easy disposal of the exhausted fluid and improved environmental safety .
ECOSAFE PLUS possesses highly stable physical and chemical characteristics during operativity (% H2O, viscosity, pH, etc.), thanks to its high
lubricity and hence to the great stability of the raw materials that compose the formulation. ECOSAFE PLUS is particularly suitable for hydraulic
circuits located in close proximity to sources of heat, thanks to its absolute non-flammability, associated to its exceptional durability and to the
optimization of the performance of the single formulation components, that give highly lubricant characteristics to the product.
Foundry Alfe CHEM has developed and tested a new product which represents a breakthrough in the class
of non-flammable hydraulic fluids. Ecosafe Plus is a biodegradable hydraulic fluid particularly suitable to be used in
hydraulic circuits located near sources of heat, due to its complete non-flammability. Ecosafe Plus formulation is
glycol-free and, compared to traditional water/glycol based hydraulic fluids, it allows for easy disposal of the exhausted
fluid and environmental safety. For what concern the technological properties, Ecosafe Plus has a greater compatibility
with most of the seals and the elastomers normally used in hydraulic plants. Ecosafe Plus has also been credited,
according to OECD 310 F, as biodegradable. In addition, Ecosafe Plus has been tested by accredited laboratories with
tribological trials (4 Ball wear test ASTM D 4172, Ball on disc test ASTM D 6425, Brugger test DIN 51347, Vickers
test ASTM D 2882). In particular, the Vickers test has shown a value of wear of the vanes, of the stator and of the rotor
equal to 25% than the one measured after the same period with the competing product; this means that Ecosafe Plus has anti-wear performances and active lubrication four times higher than the traditional products.
