The new «Lemax» 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.
