Good material:
The most important part, ELECTRIC HEATING ELEMENT, made in our own workshop, using high grade nickel chrome alloy (temperature above 1000°C), magnesium rod and stainless steel. Seamless welding ensures 5-10 times of using life than usual products in China.
Higher grade material of the pressure parts.
