The new boilers of the Prime-C series are equipped with the unique gas-air mixers and burners POLIDORO. The direct-flow collector-free heat exchanger is made of stainless steel with the expanded use of polymeric materials, as a result it does not corrode and ensures durability and reliability of the equipment.
