15. How Does it Work? • Heat, like Electricity or Water, always takes the path of Least Resistance • TCS Radiant Heaters directs heat into the Barrel, and Hence into the Melt, rather than to the Surrounding Environment • This is because the thermal resistance of TCS is greater than that of the Barrel and Melt

16. The Thermal Resistance of TCS, to the Exterior (Surrounding Air), is much Higher (>300%) than the Thermal Resistance of the MeltAs such, the majority of the Heat Energy from TCS (>80%) will be directed into the Melt rather than into the Surrounding Air

17. Alternatively, the Thermal Resistance of the Melt is Much Greater Than that of the Surrounding Air on Systems employing Band Heaters As such, the majority of Heat Energy generated by Heater Bands will be directed to the Surrounding Air, rather than to the MeltA key factor in determining the direction of heat flow is the Temperature differential between two objects. The temperature difference between the heater band and the surrounding air is much greater than between the heater band and the barrel, thus energy to the driven to the surrounding air rather than to the Melt.

18. TCS Delivers 250% more Heat to the Melt and 75% less Heat to Surrounding Air than Traditional Band Heaters • TCS • Heat Flow to Melt: 1376 BTU/ft-ft-hr • Heat Flow to Surround Environment: 349 BTU/ft-ft-hr • Traditional Band Heaters • Heat Flow to Melt: 454 BTU/ft-ft-hr • Heat Flow to Surrounding Environment: 1402 BTU/ft-ft-hr Analytical Report with full assumptions available upon request Heat Flow Calculations completed on Planar Surface with Single Direction Heat Flow

19. Placing Blankets over Traditional Band Heaters is beneficial, however the higher thermal conductivity of these blankets, and the Band Heater’s reliance on conduction heat transfer, reduces the benefit, compared to TCSAdditionally, Blankets cause Heaters to run hotter than usual, creating a higher probability of premature Heater Failure

20. Additionally, as the temperature of the heater bands rise, thermal expansion of the metal causes them to lose contact with the barrel and create an air gap between the barrel and the heaterA small gap (0.0625”) can double the thermal resistance to the melt, further driving Heat Energy to the Surrounding Air, reducing the potential energy saving benefits of the Blanketsand causing premature Heater Failure Air Gap Created by Overheated Band Heater

21. Efforts to Remove Heat from the Plant force Heater Bands to Work Overtime Fans Pull Heat from Band Heaters – So the Heaters work Harder, to Maintain Melt Requirements while also giving up Heat to the Fans
