When fitting cartridge heaters. Keep the fit between the cartridge heater and hole as tight as possible ideally applying an H7 fit.
Metal-sheathed cartridge heater with ground sheath. The special construction allows an extremely high surface loading, i.e. maximum power in the smallest possible space. Cartridge heaters are normally inserted into a metal block due to there high surface loading. Our cartridge heaters can be made with distributed wattage allowing greater heater output at the ends as opposed to the middle. They can also be made with low(24v) and high voltages as well as dual voltages and incorporate temperature sensors. We can also supply cartridge heaters with self regulating ptc elements if required and in very small diameters down to 2.8mm. We can also supply very long cartridge heaters up to 6 metres in length and heaters with special mechanical fittings and connectors.
Applications include; Plastics, apparatus construction, woodworking, paper machinery, medical technology, foundries, high vacuum technology, laboratories , packaging.

All HLP type heaters can be supplied with an integrated thermocouple. Heaters mentioned in the table are available ex-stock. High performance cartridge heaters are especially suitable for internally heated nozzles and heated torpedos where, due to space considerations, a separate thermocouple cannot be installed. The thermocouple is fixed in position, compacted and potential free insulated from the sheath or alternatively connected with the heater sheath.
Compensating leads can be connected to specified requirements. The thermocouple is galvanically separated from the cartridge sheath unless otherwise specified at the time of ordering. HLPT can also be supplied with an electrical connection between the thermocouple and the cartridge sheath, if so desired.

All HLP type heaters can be manufactured with an integrated temperature sensor i.a.w. DIN EN 60751 (PT 100) or with an integrated NTC-sensor (negative temperature coefficient) for precise temperature measurement. Typical fields of application therefore are within the car industry, electrodomestical appliances, air conditioning devices, for general machinery and medical technique appliances.

The lightly compacted cartridge heaters of this series distinguish themselves by a higher immunity against mechanical shock, and by a substantially longer useful life as compared with noncompacted metal sheathed cartridge heaters of the same surface load. They are suitable for heating liquids, gaseous and solid media and resist arduous service conditions in industrial applications.
similar to the high performance cartridge heaters type HLP, however:
Maximum surface load: approx. 6,5 W/cm2 (on the sheath)
Tolerances: Diameter: +0,2 mm of the groundless covering.
Upon request these can be ground to finer tolerances -0,02 to 0,08 mm
Length: 1.5% at least, however 2 mm
Capacity: 10%
Cartridge heaters type PMV are only produced in stock types.
The installation is easier than for the high performance heaters due to the lower surface load. Nevertheless please observe the installation instructions given for the HLP type heaters.

The high performance cartidge heater type HLPK has a conically tapered sheath with a taper ratio 1:50 i.a.w. DIN 1 for standard taper pins. The conical shape of the cartridge heater guarantees an exact force fit in the workpiece. In the case of accurately reamed bores, there is an excellent fit, as the cartridge heater in this case takes a slightly deeper installation depth. An excellent heat distribution results from the exact fit and, thus, the danger of overheating the cartridge heater is kept low. In order to get an even temperature profile, the cartridge heaters type HLPK are equipped with reinforced performance zones on both sides.
Heating of founding tanks, die- and mold making, cigarette-machines, machines for shoe production.
The workpart is provided with a pass or a blind bore according to the cartridge heater. Suitable tooling is available ex-stock.
We recommend the usage of the high temperature resistant lubricant VARYBOND REGULAR GRADE.
The disassembly of the cartridge heater is especially simplified by its conical sheath shape. A special pull out tool (Art No. 600090) facilitates the pull off process and preserves the workpiece and the cartridge heater from being damaged.

These highly compacted heating elements have been developed primarily for the heating of small parts. The sheath is made of chrome-nickel steel, material no. 1.4541 and serves as a return conductor. Therefore the high performance cartridge heaters type HLP 2.8; HLP 4.5 and HLP 5.0 may only be used for operation at low voltages up to 42 V max.
The sheath of the cartridge heaters for low voltages is not ground (diameter 2.8 mm -0.1 mm; 4.5 mm ?0.1 mm and 5.0 mm ?0.1 mm) . The bottom end is welded gas and liquid tight. The maximum sheath temperature for the ? 2.8 mm and ? 4.5 mm heaters is approx. 500?C and 750?C for the ? 5.0 mm cartridges. The connection cable for the low voltage cartridge heater with diameter 2.8 and 4.5 mm consists of a 100 mm long twisted wire which is insulated by a teflon hose. The teflon insulation can withstand temperatures up to 300?C at short time use and 250?C for permanent use. The connection end of the ? 5.0 mm heating elements consists of a ? 2 mm connection bolt with a length of 20 mm.
High performance cartridge heaters type HLP 2.8, HLP 4.5 and HLP 5 are not available ex-stock. The heating elements are produced to order within the limits shown in the tables beside.
Other lengths, voltages and powers can be supplied too.
The use of high performance cartridge heaters type HLP 2.8, HLP 4.5 with surface loading =20 W/cm2 is only permissible when there is a very good heat transfer. Cartridge heaters with a low surface load at 24 V can also be used for 42 V operation but it has to be considered that the power rating is more than 3 times higher.
High performance cartridge heaters designed for 24 V operation can also be used for 12 V operation but the power rating will then be reduced to a quarter of the nominal rating at 24 V.
Maximum current 8 A

The self regulating cartridge heater type HLPR is a compacted heating element with PTC-effect (positive temperature coefficient: performance decreases the more that the temperature increases). When the temperature on the sheath of the heater increases, the performance is automatically reduced due to the increasing resistance within the PTC elements. The cartridge heater regulates itself, any additional control equipment is not required.
The specification of the self regulating cartridge heaters type HLPR needs to be adapted to it`s individual application. Please let us know your technical requirements. Available Diameters: 10, 11, 12 a. 16 mm Available Voltages: 10?30 V; 100?140 V; 200?265 V
Compared to conventional high performance cartridge heaters with a nearly constant ohmic value, HLPR heaters consist of an integrated semiconductor element. The resistance of the heater varies and increases automatically with the rising temperature and the power consumption and the current is reduced to a minimum when the heater reaches its maximum temperature. This makes the heater very economical and extends its lifetime.

Expansion screws are always used where the tightening of the screw has to assure a long lasting and solid connection. This is mostly used for large electrical machines like turbines and generators or for large diesel engines e.g. for ships. The tightening of the screw serves to assure that the housing halves of the machines are safely fitted and that they can withstand the mechanical load during operation such as vibration or pressure. The screws can also be used for the fixation of the machines to a socket. The use of expansion screws is based on the elongation of the steel shaft within certain limits which is proportional to the applied heat. Expansion screws return back to the same length when cooling down to ambient temperature.
It is very important to only heat the screws within the shaft portion.
In order not to overheat the cartridge heaters and to achieve a good heat transfer we highly recommend the use of our installation aid VARYBOND REGULAR GRADE. Before the installation the heated zone of the cartridge heater should be covered throughout with a layer of this compound.
Heated length, unheated length, voltage, performance, connection type. It is useful to provide the heaters with an unheated length of about 150 mm to 200 mm at the connection side to prevent the connection from being thermally damaged during the heating process.
