Fire resistant hydraulic fluid
Hydra FRE is a long life hydraulic fluid with high flash point synthetic ester, provided with good lubricating properties and long equipment life. Meets the requirements of ISO 6743/4 standard as fire resistant HFDU and ISO 15380 HEES class. Hydromax FR-E can be applied as hydraulic fluid whenever operating close to heat source. Hydromax is highly biodegradable so small leakages will not cause contamination.
Applications
Hydra FRE is suitable for hydraulic applications in:
No special care is required when handling this product. Hydromax FR-E is compatible with most of the common rubbers of the mineral oil operated circuits including NBR, unless in good condition. Natural rubbers and polyurethane are not advised.
