Model: HFV-K
Brief:

Low saturated vapor pressure,narrow distillation range,high molecular weight

and pumping speed.

详细介绍

Performance

※ Low saturated vapor pressure,narrow distillation range,high molecular weight 

     and pumping speed.

※ When heated to its boiling point,the oil will eject in supersonic speed to create a 

     vacuum environment rapidly.

※ Reasonable chemical compositions, perfect oxidation and thermal stability.

※ Low back-streaming rate,oil vapor will condense into new fluid as soon as it touches cold wall.

 

Application         

※ Suitable for vapor diffusion pumps,it is available according to the final pressure only.

※ Applicable to vacuum distillation,vacuum metallurgy,vacuum coating, vacuum furnace, and etc.

※ Also be used as working fluid of diffusion pump in industries,such as electronics, aeronautics, 

     nuclear and etc.
