Freek Heat Transfer System (patent)

Freek Heat Transfer System [1 / 2] 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).

HotMicroCoil with Reflection Tube

HotMicroCoil with Reflection Tube [1 / 2] Characteristics of our HotMicroCoils with reflection tube are easy mounting and variable heat distribution. Because of its direct touch and toleranced fit, the heater allows a very good heat transmission to the nozzle. In all our HotMicroCoils with reflection tube the assembly of a thermocouple is possible and recommended for bigger diameters and power.

HotCoil with Clamp Band

HotCoil with Clamp Band [1 / 2] The HotCoils with clamp band are a highly demanded and very flexible clamping system, especially for heating larger nozzles and bushings with high power. The size-variable customizable clamp bands counteract the heating's thermal-related "lifting ambition" during heat-up and thus effectively prevent a possible critical overheating. For an even better protection all HotCoil heating elements can also be provided with an integrated thermocouple. As alternative to our standard clamping mechanism with welded clamping elements a space-saving lug clamping mechanism can be supplied.

Two Screw Clamp Band (FB)

Two Screw Clamp Band Besides its own systems Freek also manufactures original Rosemount-systems that can also be used as "Husky-replacement heater" (see spare part cross-reference list). For example the two screw clamp band (FB) and the axial clamp band (FE). Both systems can be supplied with MicroCoils in "Rosemount style" (Ø 1,4 mm) as well as MicroCoils in "Freek style" (1,3 x 2,3 mm).

Locking System

Our Locking System provides a quick, easy and reliable clamping of the heating element on the nozzle to be heated. It facilitates an effective heat transfer, as the inside sheath is pressed to the nozzle with a high level of precision creating an interference fit. Due to the method of construction of the lock, installation is possible in the restrictive space of small cavities. The lock can be operated quickly and efficiently with simple readily available tools.

"Brazed Together" Housing (BT)

Brazed Together Housing (BT) [1 / 2] Like the "Axial-" (FE) and the "Two-Screw-"(FB) clamp band systems the "Brazed Together" housing is also an original Rosemount system that is exclusively manufactured at Freek. The Freek MicroCoil 1,3 x 2,3 mm used in this type is tightly coiled on a heat-conducting precision tube and encapsulated and thermically insulated by an outer lathing part. For an even better heat transition the heating element can be vacuum brazed as an option.

The "Brazed Together" design combines many advantages: high accuracy, good heat conduction, large power density and mechanical stability.

Kappa Series (compatible with Husky)

Kappa Series [1 / 2] The Kappa series is an original nozzle heater system of our EUCOPET co-operation partner Thermetic Products Inc. USA, which we assemble as well at Freek. At the same time it is a well-proven "Husky-replacement" heater (see spare part cross-reference list).

Thermetic's Kappa series are constructed with a nickel plated copper inner sleeve and a stainless outer sleeve. The heater is sandwiched between these sleeves eliminating the heat transfer problems associated with other dual sleeved designs. The material used direct the heat inward toward the nozzle, resulting in a very efficient heater with even heat distribution. The tightly toleranced ID allows a slip fit with no clamping required. An external bendable thermocouple Ø 1,0 mm can be assembled.
