  • Design experience from more than 40 years of manufacturing

사용 방법

Heat exchange duties that benefit from the strengths of spiral heat exchangers include:

  • liquid/liquid heating, cooling or heat recovery, where one or both of the fluids may cause fouling. (See image 1)
  • vapour/liquid condensing, particularly at very low pressure and/or highvolume flow.  (See image 2)
  • The design, shape and size of the spiral channels can be customized so that they are a perfect match for the demands associated with a wide range of process fluids, thermal duties and industrial applications. (Valid for both image 1 and image 2)

Lower installation costs

Spiral heat exchangers only require a very small area for mounting and access, resulting in lower unit installation costs compared with other heat exchangers.

Strong on customized solutions

The spiral heat exchanger is a very versatile product. Many of the duties performed by heat exchangers require one channel per fluid, and this can be a distinct benefit.
