GEA is helping the food industry to maximise its environmental credentials - reducing CO2 emissions - and minimise energy use, not only by reverting to natural refrigerants such as ammonia, but also through the use of heat pump technology. A heat pump is a far more eco-friendly and profitable solution than traditional heating alternatives. Industry, local authorities and homeowners have been using them for heating applications for many years - and food factories are now starting to see the significant financial and environmental benefits of using heat pumps in production processes, especially those that require the application of heat during preparation and subsequent chilling.
