Strength in numbers: GEA robots save energy and water, especially with large herds

Round two: outstanding test results for two-box system

In a second test, a multi-box system featuring two robots was put through its paces, with similarly excellent results. Compared to previous test runs, DLG demonstrated power consumption reductions of up to 29%, with water usage dropping by as much as 18%. These savings are attributable to the economies of scale inherent in the system. The relative savings increase with each additional box connected to a supply unit – and up to four boxes can be integrated into a GEA system. Extrapolated to 100 liters of tank milk, the milking robots use only 1.1 kWh of electricity in the optimum operating scenario¹ ².

²Based on DLG test no.7424 of the multi-box system with two robots, Scenario 1 “optimized operation”, with 170 milkings, 1836 l milk per day, three main rinses, one local rinse, and heat recovery.}

Maximizing the savings

The new master-secondary configuration now takes the scale economies to new heights. In this setup, the master robot controls the other linked systems. It allows up to eight boxes to be connected to a main milk line and up to 16 to a single tank.

Additionally, when energy for water heating is sourced from a heat recovery system or an on-farm woodchip boiler, for example, the gains are even greater. However, the actual annual savings will vary depending on farm-specific and on-site conditions. “This underscores the importance of our guidance to farmers considering the transition to automated milking, allowing them to plan and build – and realize substantial savings,” notes Michael Berentzen from Sales Support at GEA.

GEA unveils TÜV-validated “Add Better” ecolabel; DairyRobot receives validation

In addition to independent testing by DLG, GEA underscores its maximum transparency approach with the newly launched “Add Better” ecolabel. With this label, GEA highlights all solutions – from industrial machines and processes to digital solutions and entire plants – that demonstrate significantly improved resource efficiency compared to their predecessors.

The underlying evaluation process – from data collection to calculation and documentation – complies with the ISO 14021:2016 standard. It has been validated by TÜV Rheinland, one of the world’s leading testing service providers. Final evaluation by GEA’s Global Executive Committee ensures that the efficiency gains are substantial enough to merit the Add Better label. The process is designed to guarantee utmost transparency for GEA customers.

GEA’s DairyRobot is one of the first systems to be validated based on its power savings and awarded the Add Better label. The company will continue to expand its Add Better portfolio with new solutions. The pipeline for the next validation round is already filled with additional candidates from the GEA Farm Technologies portfolio.
