MAIN CHARACTERISTICS

Primary heat exchanger for domestic gas-fired boilers with oval shaped tubes. The heat exchange surface is made entirely out of copper. This achieves very high efficiency rates as required by current standards for high performance heat exchangers. Turbulators are installed inside the water tubes to increase heat exchange coefficients.
Fins are braze-welded to the tubes. Heat exchanger surfaces are suitably protected against corrosion by a surface treatment patented by MUT. The 5-tube version permits the two connection fittings to be on opposite sides.
