Kelvion contributes brazed heat exchanger GK108H

- Together with heat pump manufacturers and suppliers, the Fraunhofer research project LC150 (“low charge 150 g”) has set itself the goal of researching a standardized and refrigerant-reduced refrigeration circuit using propane.
- The Fraunhofer Institute for Solar Energy Systems (ISE) has now developed a functional heat pump functional pattern with the climate-friendly and cost-effective alternative propane.
- For the research series, Kelvion has provided condensers for a refrigeration circuit with the ConBraze type GK108H plate heat exchanger.

**With the Green Deal, the EU has committed itself to becoming CO2 neutral by 2050. In Germany alone, the provision of heating and cooling makes up 40% of total final energy consumption** [[…]](http://tracking.distrib.itroot.de/tracking/click?d=lc578WgIRzAHdgbajMCFRrx_suByT-mpHPoLIQh_vg2HkkF0ZEzxJ_rAjc_35-y2a-b3RN_M1FFaWGtO9mYrFkzwPYxcAkFpxunvYaY_4iGGSZglseRBLhf4ynrti8LkzZIClsUMUFFPdKLA2jHkTnu-be25zhXbFfirealieU8YfuKbFzceD1M2xdDk_YMXK_OCKX5eDZ3bM0ogW5xNf97MdnbRY-9V9ClNt-aDPLFw6yqdYp5hI-2vWBm78Z-ZZ5ZujxHLftqkpBpxpLwBOUvucof-bT7L1TtZmgapx0W8VqzPtYxbZgcvXhkr_6a01fU3lwpfPlrP7JMyw2wY-u0obxcGXxIx0RefhRO9OWvl0)
