The Freek heat transfer system especially addresses manufacturers and users who operated their hotrunner nozzles with cast-in heaters in the past and would like to stick to their engineering know-how without paying the high price of this former heater design. The standard material of our patent pending Freek heat transfer alternative is brass, with or without coating, basically with a slit. The slit allows the assembly of an external bendable thermocouple and facilitates the disassembly, e.g. in case of a revision and can be coiled over. This is not possible at competitor's solutions. Freek's tight coiling at the heater's ends provides a maximum possible power concentration (patented).
