Introduction |
 |
 |
|
| |
| Our HotMicroCoil Heaters have a varied operative range. Most important applications are nozzles for hot-runner systems or hot melting nozzles.
Continuous process improvement is the guarantee for our continuously high level of quality. Hot-/ MicroCoil heaters can be supplied coiled to your requirements
or just straight to be coiled afterwards. For HotCoils it is also possible to integrate a thermocouple. |

2.1 MicroCoil |
|
|
|
| |
|
MicroCoils Ø 1,8 mm and 1,3 x 2,3 mm will be supplied with two transition heads and a maximum wattage of
700W as a standard. One joint transition head is possible as special execution.The types 1,8 x 3,2 mm, 1,4 x 2,4 mm and Ø 2,0
mm have a higher power density and can only be produced with one transition
head. Due to the small dimensions, thermocouples can not be integrated
in MicroCoil heaters. Standard connection is a 1000 mm PTFE insulated lead. |

2.3.1 HMC with Reflection Tube |
|
|
|
| |
Characteristics of our HMC with reflection tube are easy mounting and variable heat distribution.
Because of its direct touch and the tight fit, the heaters allows an optimal heat transmission to the nozzle.
In all our HMC with reflection tube the assembly of a thermocouple is possible.
Characteristic features
» thermocouple
» flexible cold zones
» length, winding pattern, unheated length and connection leads individually adjustable

2.3.2 Shackle Clamp Band |
|
|
|
| |
Our MicroCoil with shackle clamp band can be clamped axially with
a cam shackle. With four common power levels it covers all nozzle standards of hotrunner systems.
Note: For fixing we recommend our tool AXWZ.001 (see picture).
Characteristic features
» compact in its structural shape
» simple and quick mounting by cam shackle
» easy insertion into the conduit due to the soft nickel sheath of the applied MicroCoil

2.3.3 Two Screw Clamp Band (FB) |
|
|
|
| |
|
Freek manufactures besides its own systems also original Rosemount systems, 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).

2.3.5 "Brazed Together" Housing (BT) |
|
|
|
| |
The "Brazed together" housing is
like the „Axial (FE)“- and the
„Two-Screw (FB)“ clamp-band
originally a Rosemount system.
Therefore, apart from our Freek MicroCoil
1,3 x 2,3 mm, we can also install the
MicroCoil Ø 1,4 mm “Rosemount
style”. The heater is brazed in high vacuum process to a good heat-transmitting
precision inner housing and is insulated by an outer reflection tube.
This
construction combines many advantages: optimal fit, good heat transmission,
high power density and mechanical stability.

2.3.6 Kappa Series |
|
|
|
| |
The "Kappa series“ is an original nozzle heater system of our EUCOPET co-operation partner
Thermetic Products Inc. USA, which we assemble at Freek as well.
Thermetic's Kappa series are constructed with a nickel plated copper inner sleeve and a stainless outer sleeve.
The heater is tightly 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.

Assembly instructions
» Because of the hygroscopic characteristic of the used ceramic insulation materials they absorb moisture.
Therefore we send our HotMicroCoil heating elements usually in air-tightly closed plastic bags.
When stored unprotected in environmental air it is absolutely important to check the insulation resistance
before use and - if necessary - to dry the elements (controlled start-up or drying oven).
» Elements which are bent once must not be altered anymore. The connection area as well as the first 5 mm
unheated are must not be deformed at all.
» The temperature stress of max. 750°C at the tube is not valid for the connection area. The temperatures
arising in the connection area determine decisively the suitability of the available terminations.
» The stated nominal voltage must not be exceeded, otherwise overheat is risked.
» Generally it can be said: the better heat is carried off or flows into the workpiece respectively,
the higher the surface watt density on the sheath can be.
» A too slag fit obstructs the heat conduction and leads to heat accumulation that could overheat and enentually
destroy the heater.
» In every practice application there are working and environmental parameters which cannot be calculated exactly
in theory. That is why we recommend generally to test HotMicroCoil elements in the application under real working
conditons before series use. |
