By team, Jul 14, 2010, 08:23 2 minute reading

The heat exchanger expert Alfa Laval is adding a new range of dedicated products to its program of air heat exchangers. The air cooled CO2 gas cooler product range is specifically designed for the use of R744 as single refrigerant and features an excellent heat transfer while minimising the refrigerant charge.

Designed for the special conditions of the CO2 refrigerant, Alfa Laval has implemented a great number of design and production features in its new air cooled CO2 gas cooler product range. The heat exchangers have an innovative coil design that is based on small copper tubes and corrugated aluminum fins to provide excellent heat transfer at a minimized refrigerant charge. Specific circuiting of the gas cooling applications has been also designed considering the CO2 thermodynamic properties.

Frame, Casing and Fan features

The coil frame of Alfa Laval’s new range is made in AlMn3 for a safe protection against vibration and thermal expansion, while the casework is in galvanized steel sheet.

Alfa Laval also offers a wide range of options and features for the fans depending on the product line. They all have in common that integrated thermo contacts provide reliable protection against thermal overload and that motors can be wired to one or more common terminal boxes. Available as an option are the EC motors that also reduce the energy consumption of the remote units.
