Application areas: Heating/cooling of extruder cylinders Construction: Special ceramic heating-cooling bands of type KH 214 in widths of 30 mm, 48 mm and 63 mm are mounted directly on the cylinder in regular intervals. In cases of increased cooling requirements the flexible aluminium cooling elements  KE 300   (widths 34 mm, 47 mm, 60 mm) can be mounted between the heater bands. A stencil supplied makes alignment of the heater bands/ cooling elements in the corresponding cylinder zone much easier. In the next stage the connection flange for the cooling fan with terminal box is fitted to the cylinder using stable round facing plates. This flange includes specially-shaped air deflectors for distribution of the cooling air in the axial and tangential directions and the electrical connection with ceramic-terminalblock or industrial plug connection are also integrated. A power-supply cable of a defined length can be supplied. The size of the air outlet opening is matched to the corresponding flow volume of the intended fan, and is fitted with a grille structure for optimum airflow. The two vertically divided double-walled shrouds filled with a 25 mm thick insulating filler are then bolted to the side flanks of the fan flange housing. In the upper area they include the ECOWEMA® flap system KSHK for reduction of heat loss. Supplementary sheet metal covers can be supplied to increase the safety against being burned. These covers can be made of aluminium eloxated material in the colours red or blue. Sensor bores and apertures will be considered as far as technically possible. This construction guarantees optimum accessibility to the installed ceramic heater bands, which enables simple replacement of the heater bands without having to carry out complete dismantling of the heating-cooling assembly. In this manner, a (retrospective) conversion to a higher heating performance is made simple through the installation of further KH 214 flexible special ceramic heater bands, or to a higher cooling performance through the installation of flexible aluminium cooling elements  KE 300. A UL / CSA-certified execution is also available. Technical specification: Material housing: 0,8 mm aluminised sheet steel (stainless steel on request) Voltage/tie-in: in acc. to specification  Heating capacity: max. 7 W/cm², related to the heater bands Temperature max.: 500 °C Diameter: from 100 mm Width: from 150 mm Wall thickness of shroud: ~60 mm Accessories: Single or double fans

In order to intensify the cooling effect in the case of aircooled extruder cylinders, additional elements in the form of cast aluminium half shells with cooling fins are often fitted to the free cylinder surfaces between the heater bands. These elements increase the surface area which achieves better heat transfer between the cylinder surface and the cooling air. Whereas high costs for the casting mould and the additionally necessary mechanical processing for fitting to the internal surfaces and attaching the tensioning devices occur for the cast aluminium cooling elements, this is not the case for the KE 300 flexible cooling element. This system is modular and consists of a large number of individual cooling elements with cooling fins corrugated on both sides at a height of 28 mm. The elements are made into a row of flexible belts using two tensioning ropes and can be produced infinitely variably for all cylinder diameters. Available widths: 34 mm, 47 mm, 60 mm. The flexible aluminium cooling element is supplied ready for assembly with a spring screw connection which compensates for thermal expansion and guarantees even pressure against the cylinder surface thanks to the tensioning ropes. A sensor bore of diameter 17 mm can be made in the centre. In comparison to a cast aluminium cooling element, this solution actually has an improved cooling perfor- mance in many cases because the material used has a higher thermal conductivity, and because the gaps between the individual cooling elements and the corrugated fin surface offers a larger heat exchange surface and a more intensive mixing of the cooling air. For application cases in which particularly high cooling performance is required, we recommend combining the flexible KE 300 cooling element with the ribbed special ceramic heating-cooling bands  KH 214 

Application areas: Heating of cylindrical tools, flanges, plastification cylinders and for other industrial heating applications. Construction: Heating conductor coils fitted in temperature-shock resistant special ceramic stones. Strap retainer in 0.8 mm thick aluminised sheet steel with compensation filler (stainless steel strap retainer on request). Implementation types: Spreadable version with screw tab closure (in case of larger diameters for compensating thermal expansion with compression springs). With 2 mm compensation filler for reduction of mechanical loading in ceramic stones (fracture hazard!) when tightening down heater band. Also available as half-shells or in segmental construction in addition to mandrel heating for internal heating of moulds or rollers. Can be supplied with bores, thermal brackets and apertures as far as technically possible. Electrical power supply via contact fittings (plug) up to 16 A/250 V, cable fittings with ceramic terminal or permanently fixed connecting cable. A UL / CSA-certified execution is also available. Technical specification: Material heating element: heater conductor coils surrounded in ceramics Material strap retainer: aluminised sheet steel 0,8 mm (stainless steel on request) Voltage: in acc. w. specification Heating capacity: max. 7 W/cm²Temperature max.: 600 °C Wall thickness: 12 mm, incl. strap retainer and compensation filler Ø min.: 60 mm Width: 18 mm, increasing in 15 mm stages 33, 48, 63, 78, 93, 108 mm etc. to 633 mm

Application areas: Heating and intensive cooling of extruder cylinders. Intensive cylinder cooling enables a considerable reduction of the melt temperature whereby material degradation due to temperatures being too high is avoided, melt stiffness at the tool outlet is increased and the cooling requirements for downstream equipment can be reduced. This makes higher throughput performances and better product qualities possible. Complete, available with housing casing as heating-cooling combination HK 214, HK 216 or HK 218.Construction/version types: Heating conductor coils fitted in special ceramic stones with temperature-resistant braid connection. Cooling fins formed on the rear for increasing the heat exchange surface which the cooling air flows past. This results in a 2.5-fold increase of cooling surface related to the stone bearing surface on the cylinder. The contact surface of the stone to the cylinder is shaped so that two contact lines for improved heat transmission resultat any cylinder diameter. The ceramic stones consist of a special oxide ceramic with a high thermal conductivity of 16-28 W/mK (standard ceramic heater band: 2-3 W/mK) therefore enable a considerably higher heat dissipation than conventional versions. A completely flexible heater band can be produced using the concave and convex-shaped end surfaces of the special ceramic stones, and this can be simply placed around the cylinder and is therefore extremely quick to fit. Fixing is made using two stainless steel tensioning ropes with clamping screw and compression springs. The system enables high clamping forces, and therefore guarantees a permanently positive contact, and therefore ensures optimum heat transfer.The special ceramic stones have an extremely high fracture strength, which ensures a long heater band service life. This makes frequent assembly and disassembly possible without problems. The special ceramic heater bands are extremely suitable for use under high cylinder temperatures (e.g. during the processing of fluorine polymers with a processing temperature of more than 400 °C). Oxidisation cannot occur due to the complete lack of additional cooling sheets (radiators) made of brass or copper. If the heater band width is 48 or 63 mm, centrally located sensor bores are possible. Considerably lower energy consumption than in systems in which the heating resistor is pressed or cast in aluminium. Simple, modular setup enables short delivery times.UL / CSA-certified execution availableTechnical specification: Voltage: in acc. w. specification Heating capacity: max. 7 W/cm²Height: 21 mm, incl. cooling fin Available widths: 30 mm, 48 mm, 63 mm Diameter: from 60 mm

For prevention of heat loss caused by convection on the heating-cooling combination. Retrofitting is possible provided that the air outlet of the heating-cooling assembly is in the 12 "o'clock" position. Special versions for positions at 3 or 9 "o'clock" are also available.  Installation takes place on an existing air outlet dome or directly on the housing casing. The airflow created by the fan opens the flaps, which then close automatically when the fan is switched off. Heating energy losses in the heating phase and during production are effectively prevented, which leads to a reduction in the switch-on duration of the heater bands and thus to lower energy consumption. The effectiveness of the installed air cooling is not restricted. The flexible ISOWEMA® insulation covers represents an ideal modification.
