L-HV low temperature hydraulic oil series products are made of CTL base oil with multi-functional additives and advanced blending technology. Strict hydraulic pump and use test show that the oil not only has excellent anti-wear performance,but also has excellent low temperature performance,low pour point,can ensure the construction machinery or equipment in cold or cold area environment easy to start and normal operation.Excellent viscosity temperature performance,viscosity index are above **0,to ensure that hydraulic equipment in the case of large temperature variation range of good lubrication,cooling and sealing,good emulsification resistance and rust resistance, good oxidation stability,hydrolysis stability and thermal stability.
