4. 1991 - Initial cartridge heater produced

5. 1998 - U.S. coil heater production launched

6. 2003 - Production facility expanded

7. 2004 - Heater based assemblies unveiled

9. 2010 - Renamed Nexthermal to emphasize commitment to heat management solutions worldwide. Location, manufacturing facilities and staff remain the same.- Introduced eheat, energy efficient cartridge heaters

10. Let us be your R&D! If heat is essential to your process, systematic heat management thinking and development is key to your competitive edge. Nexthermal is committed to make our best resources – people, tools, testing, and facilities – available to accelerate your success. Your R&D department just cost effectively extended it’s capabilities.

11. Idea Design Prototype Testing Analysis Typical Product Development Cycle Design modification for each learning phase Iteration for each learning phase, multiple expenses of prototypes and testing for each design

12. Design Analysis Verification Idea Design Prototype Product Development with CAE Design modification Lower risk of final testing not meeting customers needs

14. In 2001, Nexthermal was the first electric heater manufacturer in the world to become certified under ISO 2001: 2000 standard

15. All outgoing product is 100% checked for safety, performance and fit metrics

16. All raw materials are checked with traceable certificate to prove acceptance

18. Stainless steel 321 vs. 316

19. Ti content resists intergranular corrosion at higher temperatures

20. Heat treated in special atmospheric oven to realign grain structure for flexibility

21. High purity MgO reduces electrical leakage and improves safety

22. Further processed by Nexthermal for performance

23. Heat treated resistance wire to provide long life

24. Construction

25. Highly compacted, improves heat transfer - better heater life

26. Unique assembly process controls wire position after forming

27. Controlled heat pattern

31. Minimum heat loss with adequate wattage distribution to offset

32. Tip geometry to limit heat loss but engineered to prevent drool (correct design of contact and sealing surface)

34. Lower duty cycle = Higher efficiencyPressed in Brass vs. Reflection Sheath Pressed in Brass Pressed in Brass with reflection

36. Minimum heat loss with adequate wattage distribution to offset

37. Tip geometry to limit heat loss but engineered to prevent drool (correct design of contact and sealing surface)

39. Nozzle Profile without Reflection Tube Good heat profile, but open coils allow heat loss

40. Thick Film Heater (competitor) Too much heat in the center, not efficient

41. Injection Nozzle Profiling with Reflection Tube Good heat profile Wattage reduced by 20% Higher efficiency Lower scrap

42. Innovative Solutions

43. HotFlowModular Circulation Heater By managing the fluid path and heat transfer area, we developed a high thermal efficiency fluid heater that outperforms standard immersion heater designs

44. HotFlow - Improving Electric Vehicle Battery Performance and Life

45. Hole Punch Heater Due to the way standard cartridge heaters are used, heat is being created at exactly the wrong place for the application need Using a replaceable mini coil on a replaceable tool Tool wear is independent of heater, replace only when needed Heat is focused into the tool

47. Quick, easy removal of heater after burn out

48. Improved heat transfer due to special composition

49. Special compound acts as a corrosion barrier

51. Replaces SS321 heater sheath with a highly thermally conductive alloy

52. SS321 = 16 – 22W/mK

53. New alloy = 159 W/mK

54. 622% improvement in rate of thermal transfer from heater to jaw

57. PCR Well Heating System

60. Pictures create understanding, and choices

64. Linear and Contact stress analysis

65. Static

66. Drop test

67. Fatigue

68. Frequency model analysis

69. Buckling analysis

70. Pressure - flow analysis

72. Plate design Standard heater power in each location 8 cartridge heaters Hot due to thicker section Note shadow effect behind bolt hole

73. Plate design Staggered heater power, without internal wattage distribution Reduced temperature variance, further improvement possible with distributed wattage

74. Packaging Jawwithout wattage distribution 66% of jaw face within 6°F

75. Packaging Jawwith wattage distribution 86% of jaw face within 6°F
