Annotation. In the article the replacement is substantiated in high-pressure piston and cylinder units of the working fluid from a mixture of glycerin and ethylene glycol at PES-3, which are non-toxic, low flammable and which do not change viscosity with temperature changes.
Piston and cylinder units with back pressure for piston pressures 1; 1.2; 1.6 GPa are considered. The parameters of the piston and cylinder units are determined using mathematical modelling.

Key words: high pressure piston and cylinder units, working fluids, modelling.
