The all-round heat transfer solution. Exceptional compactness and self-cleaning design make Alfa Laval spiral heat exchangers extremely versatile. Ideal for everything from dirty fluids to high vacuum condensation.     Unique shape has unique properties 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 a 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 vapour side pressure drop - Column mounting of condensers reduces installation costs - Design experience from more than 40 years of manufacturing
