We render a supreme quality range of Plate Heat Exchangers as per the varied international quality standards. The product range is extremely wide and is used in duties for heating, cooling, heat recovery, evaporation and condensation in industries ranging from HVAC, refrigeration, engine cooling, dairy and food to heavier processes like chemical processing, oil production and power generation
Alfa Laval spiral heat exchangers are the ultimate problem solver in extremely dirty and fouling process duties. The self-cleaning features inherent in the design, give unparalleled uptime between service intervals and quick and easy service turn-around.
A spiral heat exchanger is a circular heat exchanger with two concentric spiral channels, one for each fluid. These curving channels provide extremely efficient heat transfer and good flow conditions for a wide variety of fluids.
The standard design consists of a spiral wound from two sheets of metal to form two concentric spiral flow passages. The different media flow counter-currently in these channels, from the centre to the periphery and vice versa. The process channel is open on one side and closed on the other, whereas the water channel is closed on both sides. Each channel has one connection in the centre and one on the periphery.
The design is particularly suitable for use with fluids that tend to cause fouling, such as the sludge from wastewater treatment of all kinds. The spiral flow and continuously curving passages create turbulence in the flow, which results in a constant scouring action. In addition to this turbulence providing efficient heat transfer, it results in a self-cleaning effect that flushes away any accumulations of deposits as they form. This helps prevent fouling and ensures only a minimum of downtime for maintenance.
Applications:
- Gases: pure vapour and mixtures with inert gases.
- Vapour/liquid: Top condensers, reflux condensers, vacuum condensers, vent condensers, reboliers with fouling fluids and gas coolers.
