Technical Features

›

Finned coil design

The finned coils are manufactured with copper tubes and aluminium fins. The fins feature a high-efficiency corrugated profile designed to maximize heat transfer performance while ensuring optimized air distribution and minimizing droplet carry-over.

For corrosive or demanding environments, a range of protective solutions is available on request, including stainless steel tubes, pre-coated aluminium fins, and specialized coil coatings to enhance durability and corrosion resistance.

Frame and casing

Depending on the product range, the units are manufactured with galvanized steel and aluminium frames, finished with a durable RAL 9016 epoxy coating to ensure long-lasting protection.

For installations in particularly aggressive environments, stainless steel frame is available on request, providing enhanced corrosion resistance and extended service life.

Fan technology

The product range incorporates advanced fan technology for each application. Cubic and dual flow coolers are equipped with high-efficiency external rotor fans, while radial coolers feature state-of-the-art electronic plug fans capable of generating high static pressure.

Careful fan sizing and selection ensure the perfect balance between airflow, energy efficiency, and acoustic comfort, providing reliable and high-performance operation in every installation.

Testing

All coils are subjected to pneumatic testing at the designated test pressure to guarantee the highest level of leak integrity.
