Obstgut Margaretenhof

Obstgut Margaretenhof is a forward-thinking fruit farm focused on expanding its operations with innovative, cost-effective, and reliable refrigeration solutions to enhance product quality and operational efficiency.

  • Location : North Rhine-Westphalia, Germany
  • Products : GHP
  • Facilities : Farms
  • Project : Obstgut Margaretenhof – Grafschaft
  • Products : 2 × gas motor refrigeration systems, 2 × refrigeration kits, 2 × motor heat recovery units
  • Refrigeration-capacity : 126 kW
  • Heating capacity : max. 60 kW engine waste heat

Every year, the Obstgut Margaretenhof fruit farm in Grafschaft-Oeverich relies on efficient refrigeration to preserve its harvest. Expanding its operations, the farm adopted Yanmar’s gas motor refrigeration systems, one of the first applications of this technology in commercial refrigeration. The new system, powering four cold rooms with a total volume of 2,600 m2, offers 126 kW of refrigeration output and utilizes engine heat recovery for defrosting and heating process water. Collaborating with Berndt Enersys, the farm achieved significant cost efficiency and reliability, with the system providing full return on investment in just two years. This innovative approach reduces strain on the local power grid and enhances the farm’s operational efficiency.
