Britannia Heatex is one of the world’s leading manufacturers of air-blast heat exchangers. Our standard air-cooler design, like our reputation for superior quality and performance, has been honed over many years to be the very best available on the international marketplace.

Much of this results from the use of an ElfinBlock core, arguably the most advanced extended surface technology in the world. Elfin products, such as ElfinBlock, IntegrElfin, ElfinMaster, VantageFin, JouleFlo, CrimpFin, CARFin and OvalBlock are manufactured using custom built, state-of-the-art CNC machines incorporating advanced electronics and linear motor technology. This results in excellent fin-to-tube contact for optimum thermal conductivity and increased consistency of fin placement for minimal pressure drop in stacked rows. The Elfin manufacturing process also imparts the ability to incorporate many enhancements such as louvers, air turbulators and vortex generators. See here for a basic overview of the choices available when designing heat exchangers using Elfin products.

An absolute refusal to compromise on quality and durability pays dividends in greatly improved characteristics:

Compare this to some of the alternative construction methods used by many of our competitors, one of the most common being bullet-expansion. This method commonly results in varying levels of contact between the tubes and the fins as variations and inconsistencies in tube diametre, thickness and ovality take their toll. This construction method also greatly restricts material choice, tube thickness and shape.

Common applications include:
