BITZER products and experiences with refrigerant blends

BITZER has accumulated extensive experience with refrigerant blends. Laboratory and field testing was commenced at an early stage so that basic information was obtained for the optimizing of the mixing proportions and for testing suitable lubricants. Based on this data, a large supermarket plant – with 4 BITZER semi-hermetics in parallel – could already be commissioned in 1991. The use of these blends in the most varied systems has been state-of-the-art for many years – generally with good experiences.
