PRODUCTS FOR CO2 SYSTEMS The employ of Carbon Dioxide (CO2, R744) in the refrigeration and air conditioning plants, is increasingly holding the interest of our field’s professionals, due to its no-toxic no-inflammable features. The need to reduce the pollution limiting the ozone layer thinning (Montreal, 1987) and the discharge out to the atmosphere of greenhouse effect causing gasses (Kyoto 1999) make of the employment of Carbon Dioxide one of the most valid alternative to Synthetic Refrigerants. Castel proposes a wide range of products opportunely modified to be suitable with CO2 systems; nevertheless...
