Hydromax HT ECO

Hydro treated based high performance readily biodegradable hydraulic fluid


Hydromax HT ECO is a range of high performance hydraulic and hydro turbine fluids, based on the latest technology hydro treated base oil and ash less (zinc free) additive technology. The use of special additive packs warrants optimal performance and a long service life. Hydromax HT ECO combines high viscosity – temperature characteristics with good extreme pressure and anti-wear properties for reliable and trouble-free performance even at high operating temperatures. The long lifetime of Hydromax HT ECO (up to 5 times longer than standard mineral Hydraulic oils) makes this product not only Biodegradable and non-toxic but very sustainable. The long life and cleanliness results in less waste material, low oil filter consumption and as a result of very low friction a proven lower energy consumption (between 3 and 5%) can be generated. Hydromax HT ECO has very good water separation properties which allow draining of water from systems when water intrusion is seen. Conductivity for Hydromax HT ECO is very low which allows this oil to work as a Transformer and Hydraulic oil at the same time.


  • Particularly suitable for hydraulic equipment & hydro turbines which are environmentally sensitive
  • Can be used in all available hydraulic applications, as well as light gear boxes and is perfectly suitable for general lubrication purposes
  • Suitable for ROV units
  • Developed to provide trouble free operation, especially in cases where a conventional based hydraulic fluid fails (sludge and deposit creation at higher temperatures etc.)
  • Recommended for high pressure hydraulic systems or equipment operating over wide temperature ranges where it is critical to retain viscosity-temperature characteristics under high shear conditions
  • The high viscosity index Hydromax HT ECO ensures a low start up viscosity, as also a stable protecting lubricating film at high operating temperatures
  • Formulated to meet and exceed; Denison HF-0, Eaton Vickers M-2950-S and I-286-S, Bosch Rexroth DIN 515244 Part 3
