Arctigo, ALFA LAVAL’s new range for industrial cold rooms

EUROPE – ALFA LAVAL brought a whole new dimension of chill to Chillventa 2014 with their new industrial air cooler, the Arctigo. This equipment is suitable for use with the natural refrigerant R744 (CO2). The Arctigo is a line designed to keep fresh and frozen goods refrigerated at a range of temperatures from 10°C to – 40 ° C. The highly adaptable nature of the Arctigo means that it can solve various problems and is the perfect blend of ALFA LAVAL’s creativity, experience and technological know-how.

ALFA LAVAL’s Arctigo IS is a range of simple discharge air coolers for cooling and freezing applications in medium and large cold rooms. It has a rated capacity of 3 to 250kW and can achieve design pressures between 30 and 60 bars when using CO2.

A versatile range and a modular concept
The Arctigo’s versatility ensures that it can be used in many different applications ranging from keeping products fresh to freezing meat, fish and poultry. In addition, it can be optimized for use in processing chambers and distribution centers. This is achieved in part due to the flexibility of its fitting, which can accommodate several different fan casing and hood positions.
The flexibility of the Arctigo IS range also stems from its ability to be configured with square or triangular pitched coils. Squares pitchs are ideal for applications that demand the relative humidity to be kept high, as they enhance the surface area for less defrosting, longer cooling periods, lower air drop pressure and lower fan power consumption. Triangular pitches, on the other hand, result in a lower fin temperature and greater capacity per m² of the coil surface, which allows for a more compact cooler design.


Quality guaranteed due to standard features

The Arctigo IS features:


  • 1 to 8 fans, diameters 450 up to 1000 mm
  • Made of heavy-duty material that is corrosion resistant
  • 7 basic coil block modules
  • Hinged fan rings
  • Air volumes 3000 up to 120000 m3/h




  • Energy efficient
  • Robust design
  • Optimal material thickness and weight ratio
  • Easy to install and maintain
  • Opportunity to optimise either the blow-through or draw-through design
  • Reduced risk of sputtering and even air distribution over the finned tube coils

Optimised defrost systems
The Arctigo’s defrost system is also designed to provide the greatest possible efficiency at the lowest possible operating costs to the user. Each defrost system can be optimized for specific applications and conditions and even has the ability to take into account past user behavior. Minute details such as the frequency of door opening and the position of air coolers can be taken into account during installation to ensure optimal performance.
