Depending on the heat transfer medium in the geothermal collectors, a distinction is drawn between direct heat and brine systems. The direct heat system (GMDW series) uses horizontal collectors as standard. The brine circuit required for brine ground source systems, comprising a circulation pump, heat exchanger and expansion vessel, are not required for this.All refrigeration components are brazed. This results in even greater operational reliability, as there are fewer components as well as improved system efficiencies and lower running costs.
OCHSNER pioneered this technology 30 years ago. Thousands of installed systems, which have already been operating reliably for decades, are proof of our expertise and experience in this area. In 1992, OCHSNER was awarded the Austrian state prize for innovation for this system which at that time was unique. With commissioning undertaken exclusively by certified OCHSNER customer service engineers, you are still assured of the highest possible energy efficiency and operational reliability today.
