A spiral heat exchanger is precisely what it says – a circular heat exchanger with two concentric spiral channels, one for each fluid.

The curved channels provide optimum heat transfer and flow conditions for a wide variety of fluids, while keeping the overall size of the unit to a minimum.

Features and benefits of the Spiral Heat Exchanger:

Fully engineered to meet the needs of every customer
Self-cleaning effect reduces operating cost
Low maintenance cost due to easy access
High heat transfer efficiency, higher than in shell & tubes
Unique ability to handle two highly fouling fluids
Every unit is fully drainable
Condensers have virtually no vapor side pressure drop
Column mounting of condensers reduces installation costs
Design experience from more than 40 years of manufacturing

Typical uses are:

Liquid/liquid heating, cooling or heat recovery, where one or both of the fluids may cause fouling.
Vapor/liquid condensing, particularly at very low pressure and/or high-volume flow
