The TCS Heater Band System provides an energy efficient alternative to conventional barrel heating bands for plastic injection, blow molding, and extrusion machines. It uses embedded radiant heating elements in a ceramic fiber material to heat machine barrels. This allows for 30-50% reduced energy usage compared to conventional bands, faster heat up times, tighter temperature control, and optional efficient cooling. Customer case studies show payback periods of less than two years. The TCS system can be used on machines of any make and model to lower energy costs and improve productivity.

9. Two Designs…This product is offered in two designsThe two designs are necessary toaccommodate a larger range of barrel diametersThe two designs are “Segmented”and “Clamshell”The “Clamshell” designaccommodates barrel diameters from2” - 9.9”The “Segmented” designaccommodates diameters from10” - 17”9

12. TCS Heater Band System…Manufactured from a vacuumedformed ceramic fiberCompleted segment design iscomposed of multiple segments, theclamshell two halvesWith the segmented design thenumber of segments is determined bythe barrel diameterBoth designs are wired in series, thesegmented design is assembled withVelcro, the clamshell with metalclampsBoth consist of embedded radiantheating elements12

14. The Cooling OptionThe bands are designed to accommodate cooling if requiredThe heating elements channels are also used for coolingOptional blower can be addedAir is pulled through the channels directly across the surface of the barrel14

15. The Cooling Option15High Radiant Energy release from exposed element permits much faster heat up and response time than conductive type band heaters. Does not depend on maintaining good barrel contact to conduct heat to the barrel.Faster & more effective air cooling directly on the barrel. Do not have to cool the band heaters or aluminum clamshells first. Does not depend on maintaining good barrel contact to conduct heat away from barrel.

16. During Heating & CoolingThis system totally encapsulates your barrelHeating elements do not require direct contact with the barrelCooling is more efficient, air has direct contact with the barrel16

17. Benefits of the TCS SystemReduced Energy Consumption of conventional bands by 30% To 50%Faster Heat Up Time 30% To 50% Faster Tighter Temperature Control +/- 1degree FImproved Worker Safety Safe to the touch under operating conditionsReduction In Air Conditioning CostsLower Maintenance Costs17

18. How Saving & Benefits are AchievedWattage of the TCS system is reduced by 30%Bands cycle less due to superior insulatingAdditional savings with reduced heat-up timeConductive heat into your facility is almost eliminated reducing air conditioning requirements18

19. Maintenance SavingsLower wattage equals longer band lifereplacement costs are reducedThe single segment or clamshell designallows for ease of replacementmaintenance time and cost is reduced with single replacementsLead wires and terminations run much coolerReplacement inventory is reducedreducing inventory costs19
