At the recent commercial fruit growing, distillation and agricultural technology show Fruchtwelt Bodensee in Friedrichshafen, southern Germany, Kratschmayer GmbH showcased its latest propane chillers and heat pumps, according to the magazine Fresh Plaza.
The company is advocating using this technology instead of ammonia for fruit and vegetable storage.
It has already made a number of installations in Germany with this natural refrigerant.
Kratschmayer plans to encourage customers to tap into German government subsidies for “non-halogenated and low-GWP refrigerants” to trigger wider uptake of this technology.
Natural or non-halogenated refrigerants like CO2, ammonia and hydrocarbons (such as propane, isobutane and propene/propylene) are naturally occurring and do not need to be chemically synthesised.
The subsidy scheme seeks to reduce the energy consumption of refrigeration and air-conditioning systems and runs from 1 January 2017 until 1 January 2019.
The propane chillers have had risk assessments and gained the acceptance of German certification agency ZÜS.
The chillers have a remote monitoring system that helps with early fault detection, analysis, optimisation and troubleshooting. If there is a problem with the chiller, it automatically shuts down.
