Main features

Exclusive LU-VE technology – Round refrigerant-fluid conduits

In the STN tubeless condensers, it is the fins themselves which form the conduits of the fluid: the high, circular “funnel”-type fin collars are inserted one into the other and copper brazed in an inert atmosphere furnace. This method of construction gives the highest possible conductivity, as the gas virtually flows through the fins.

Plastic fan shrouds (model C) can be supplied for this type of condenser.

Every condenser undergoes a special surface treatment process: phosphatisation, double-immersion painting and oven drying. This treatment ensures total resistance to corrosion, especially in salt-air marine environments.

STN condensers have been tested in salt spray chambers according to ASTM B117 for 400 hours.
