FINNED COILS IN 6 DIFFERENT GEOMETRICAL CONFIGURATIONS

We produce finned coils for heat exchange between air and a primary fluid according to the drawings or technical specifications supplied by the customer.

Advanced engineering systems, state-of-the-art technical know-how and experience enable us to offer the most appropriate solutions from the technical and economic standpoint.

The geometrical configurations and construction possibilities are listed in the tables below.

Eurocoil systems can be manufactured with:

• copper tube of different thicknesses and with smooth or inner grooved surface;
• fins, with self-spacing collar, in aluminum, pretreated aluminum or copper;
• carpentry in galvanized sheet metal, stainless steel, copper, brass or aluminum;
• copper manifolds with connectors for welding or with threaded couplings depending on the application.

All heat exchangers are tested at 10 bar if functioning with water or at 30-50 bar if functioning with refrigerants.

We produce CO2 heat exchangers, testing them at 100% in accordance with standard 2014/68/UE (PED).

On request they can be tested under different conditions.

MATERIALS FOR FINS

Flat aluminum

Standard application.
Treatments such as heresite or cataphoresis are possible.

Geometrical configurations 2525 and 2512.

Corrugated aluminum

Standard application.
Treatments such as heresite or cataphoresis are possible.

Geometrical configurations 0517, 0822, 2522, 1026 e 1226.

Louvered aluminum

Standard applications; louvers increase the exchange coefficient on the air side.

Geometrical configurations 0517, 0822 and 2522.

Flat hydrophilic surface

In coils for air cooling, this treatment prevents natural oxidation of the aluminum, improves drainage of condensate and reduces the air pressure drop.

Geometrical configurations 2525 and 2512

Corrugated hydrophilic surface

In coils for air cooling, this treatment prevents natural oxidation of the aluminum, improves drainage of condensate and reduces the air pressure drop.

Geometrical configurations 0517, 0822, 2522, 1026 and 1226.

Louvered hydrophilic surface

This treatment prevents natural oxidation of the aluminum, improves drainage of condensate and reduces the air pressure drop; louvers increase the exchange coefficient on the air side.

Geometrical configurations 0517, 0822 and 2522.

Flat Goldlack

Prevents oxidation and protects against certain corrosive agents.
