Heater With Cooling Cover

Cooled Ceramic Heaters are designed for super efficient and economical cooling on extrusion and blow molding machines.

Heater band is 60% open by perforated metal sheet which ensures maximum surface exposure for better cooling. The heater band is covered with Blower cover for mounting the Blower. Advantages of air cooled over liquid cooled operation includes lower cost, easy replacement, low maintenance, no leakage problem and uniform temperature control.

Historically, liquid cooled Cast-In Heaters have been the more frequently employed method of controlling the melt temperature of extrusion barrels. There is no doubt about the effectiveness and speed of liquid cooled castings in removing heat from the extrusion process. However, there are a number of drawbacks that primarily relate to maintenance-associated issues. Air Cooled Band Heaters are virtually maintenance free and therefore, when properly installed and applied, have the capability to far outlast their liquid cooled counterparts. Since cooling tubes are not used, the possibility of breakage, cracking or becoming clogged with brine or mineral deposits is not a concern.

Additionally, Air Cooled Band Heaters do not require an expensive cooling tower or heat exchange system, extensive plumbing systems and labor for installation. These factors along with the benefit of being maintenance free make Air Cooled Band Heaters an economical and practical source for your extrusion heating and cooling application.
