Universal PUR high-pressure unit with hydraulically driven pulsation-free metering using piston pumps. The PSM700 is suitable for the spray processing of filled and unfilled elastomers as well as foamed polyurethanes and polyureas in stationary and mobile applications.



  • Feeding from barrel pumps or heated process vessels

  • Fully automatic close-loop control of mixing ratio and flow rate

  • Operation via HMI with touch screen

  • Process visualisation and recipe memory

  • Instantaneous water heater and hose heater controlled separately for both components

  • Rinsing solvent-free mixing heads with high-pressure impingement mixing

  • Spray processing of coatings, elastomers, polyurea and rigid foam

Equipped with a completely new hydraulic drive, the high-pressure machine features highly flexibility in terms of flow rate and mixing ratio. The ingenious drive principle makes it very easy to set and control the required mixing ratio. This ensures maximum safety even with basic equipment. The modular design can grow in line with ever increasing customer requirements in terms of production reliability and ease of use.

ISOTHERM also offers fully equipped mobile spray equipment that are installed in a truck or mounted on a trailer and provided with an electrically heated hose package of 10 to 90 m.
