Product overview of insulating sleeves

“Energy costs” and “reduction of CO2 emissions” are buzzwords that we hear and read about across all media today. The increasing energy costs are an issue in every company.

With our Gräff – ISOMA insulation sleeve, you can reduce heat loss through heat conduction and minimize the power consumption by improving the thermal efficiency, or achieve a shorter heating time with the same heating capacity.

As a contribution to energy cost reduction, a consumption minimization of between 20 – 40% can be realized, depending on the design and application.
Other substantial advantages are a faster thermal adjustment of the cylinder to the desired operating temperature, an increase in occupational safety by lowering the surface temperature and a noticeable improvement in the indoor climate in the production halls.

Installation of the Gräff – ISOMA insulation sleeve is possible anytime on new or also on existing production machines.
