Round, seamless copper tube rolled up into the shape of a pancake, thus the name ‘pancake’ coil. Available in both Copper and Copper Nickel alloys and a range of sizes to suit the application.
Predominantly used in the air conditioning and refrigeration market, pancake coils also feature in sectors such as automotive and medical.
Material can be supplied in customer specific lengths dependant on dimensions, with the option to customise markings and packing.
