Definition
Low fin tubes/integral fin tubes are increasingly being used in various fluid heat exchangers, such as in coolers, condensers, and chillers. Typically constructed from materials such as carbon steel, stainless steel, alloy or copper, providing durability and resistance to corrosion.
Low fin tubes have the following core performance advantages:
Application ( Not limited to the following )
*Oil Refineries: Resists sulfur-containing atmospheres (alloy options).
*Power Plants: Handles steam condensation efficiently
*Marine Applications: in heat exchangers for marine applications
*Air Conditioning and Refrigeration:in condensers and evaporators of air conditioning and refrigeration systems
*HVAC Systems:Lowers energy use in chillers.
*LNG Processing Units
