AlfaSolar SR
Air cooled radiators AlfaSolar SR have been designed for heavy industrial cooling applications for cooling of various process liquids. Dual coil models are available for simultaneous cooling of LT/HT engine circuits. Applications include diesel and gas engine cooling, turbine cooling, oil cooling and various other processes (transformers, air compressors, etc.)
Standard configuration
- Finned coil F5
- Cu-tubes ø 12.7 mm
- corrugated Al-fins 0.14 mm, no turbulators
- fin spacing 2.3 mm - Two casing widths (SRM=1630 mm, SRD=2400 mm)
- Flanges PN10/16 according to DIN 2642
- Direct driven axial fans, suitable for use with frequency converters. When designing a frequency converter system, the general guidelines for allowed cable lengths, dU/dT and/or sinus filters etc. have to be considered.
- Axial fans in a range of different fan speed executions. Available in two fan diameters: 914 mm (1 to 14 fans) or 1240 mm (1 to 7 fans). All fans have corrosion resistant fan blades and fan guards.
- Fan motors available for various power supplies. The motors are squirrel-caged motors for outdoor use built to IEC standards and provided with condensing water outlets and shaft seals together with F-class insulation. Protection class IP54/55, except for the condensing water outlets. Motors pre-wired to lockable safety switches.
- All casing parts are of hot dip galvanized steel plates.
- Specifically designed for installations with several radiators installed side by side.
- Adjustable mounting legs ( ~120/420/620 mm)
- Fitted with header tube protection panels.
- Manual venting and draining valves.
- Partitions between fans for regulation of the cooler capacity by means of separate use of the fans.
- Standard vertical transport position, fixed on a wooden pallet. Suitable for truck transportation or loading into a container. Wooden seaworthy packing on request.

Como funciona
Os trocadores de calor a ar com serpentinas aletas da Alfa Laval foram projetados para alcançar uma troca de energia térmica otimizada entre o ar e um refrigerante ou fluido. O “coração” dos nossos trocadores de calor a ar é a serpentina aletada, composta por um circuito de tubos interconectados e aletas para aumentar a superfície de troca térmica. Graças à combinação de variáveis de projeto (materiais da serpentina, geometria, design da carcaça, tipo de ventilador), as unidades a ar são trocadores de calor versáteis, com ampla variedade de aplicações em diversas indústrias. A Alfa Laval fornece produtos de trocadores de calor a ar com serpentinas aletas para uma grande variedade de aplicações.
Resfriadores de líquidos a ar (radiadores/dry coolers)
Os trocadores de calor a ar podem ser usados para resfriar diversos líquidos de processo. Para essa aplicação, o líquido quente de processo circula pelos tubos e é resfriado pelo ar ambiente relativamente frio, que é forçado a passar pela serpentina.
Os trocadores de calor a ar para resfriamento de líquidos de processo são chamados de “radiadores”. Os resfriadores de líquidos a ar para aplicações HVAC e sistemas de energia total são chamados de “dry coolers”.
