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

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
