Safety Devices for Protecting Refrigeration Systems from Excess Pressure
GEA GPVs are designed for installation in the oil return line between the lowest point of the flooded evaporator and the compressor. By design the valves are kept open by a compressing spring so the oil-refrigerant mixture runs into the oil reservoir. Once filled, hot-gas pressure which is inserted by a connector on the cover, closes the GPV and concurrently increases the pressure on the reservoir via an overflow bore. This pressure is used to impel the collected oil back to the compressor and thus to drain the oil collection container.

The impact of global warming is increasingly apparent all over the world. Towns and cities everywhere face the same challenge: providing their communities with reliable, affordable, sustainably sourced heat. GEA spoke with an expert in the field, Kenneth Hoffmann, Manager, Heat Pumps at GEA Heating & Refrigeration Technologies, about tackling global warming faster.
Something caught Farmer Tom's eye. Instead of another product demo, GEA showcased innovations via AR. That's only the start of GEA's interactive digital farm.
GEA scientists are working with researchers at the Graz University of Technology to configure a homogenization process and technology that turns eucalyptus pulp into 3D-printed, organic structures mimicking human veins, arteries and other tissues.
