BTW250AS is adopting the breakthrough technology Hypertwain®. Developed to provide a solution for all the reversible systems, where the demand to have an equally efficient heat exchanger in both co-current and counter-current, is yet to be meet. With BTW250AS, not only efficiency at full load but also partial load conditions have been brought to the highest level. Also, due to our technology, freezing robustness during defrosts and distribution stability have been drastically improved. Suitable in capacities up to 300kW with all low GWP high pressure refrigerants.
