제품 사양



제품 상세 설명

Hot Rod Cartridge Heater는 가열 표면 전체에 균일한 가열과 우수한 열 전달률을 제공하도록 설계되었습니다. 개별적으로 제어 가능한 가열 구역을 통해 구역별 가열 및 분산 전력 요구 사항과 같은 다양한 프로세스 요구 사항을 정확하고 균일한 온도로 달성할 수 있습니다. 히터는 더 낮은 내부 온도를 유지하기 위해 외장과 발열체 사이의 간격을 최소화하여 구성되어 더 높은 와트 밀도에서 더 작은 크기의 히터가 작동합니다.

고순도 산화 마그네슘 충진재를 사용하여 금속 외피에서 분리되고 특수 설계된 코어에 감긴 고급 니켈 크롬 저항 와이어로 구성되며, 정교한 스웨이징 공정을 통해 SS/Inconel 튜빙에서 모두 중앙에 집중되고 단단히 압축되어 에어 갭이 최소화된 히터가 생성됩니다. , 부식 및 산화에 대한 높은 내성, 수명 증가로 인해 당사는 카트리지 히터를 고성능 및 더 긴 내구성으로 동급 최고의 제품으로 만듭니다.

Construction

1. High-Temperature Lead Wires for temperatures up to 550° C

2. High Impact Ceramic Cap retards contamination and is suitable for high vibration applications. Deep holes in the cap prevent the fraying of lead when bent.

3. Nickel Chromium Resistance wire for maximum life, evenly wound for even heat distribution.

4. High Purity magnesium oxide fill selected for maximum dielectric strength and thermal conductivity, highly compacted for maximum heat transfer.

5. Stainless steel sheath / Inconel sheath for oxidation and corrosion resistance in a wide variety of environments.

6. Tig welded end disc to prevent contamination and moisture absorption



Heater Construct

Termination Options

Ceramic Bead

When the temperature at the exit of the heater exceeds 590°C, ceramic beads protect the wire until conventional insulation can be utilized.

 

 

Copper Elbow Flexible SS Conduit

Right angle flexible conduit can also be attached with a copper elbow. This method can also be used to attach a right-angle flexible conduit to stock heaters.

 

Crimped on leads

Crimp-on leads are generally used where the temperature at the end of the heater exceeds the maximum allowable temperature of the lead wire.

 

 

Right Angle Leads

Right angle leads are ideal for applications with tight spaces. Leads are covered with a silicon impregnated fiberglass sleeve where they exit the heater.

 

 

Right Angle SS Flexible Conduit

It offers the same advantage as that of stainless steel flexible conduit but the right angle arrangement allows it to be used in tight spaces.

Sleeving

Silicon Rubber Fiber Glass Sleeving and Fiber Glass Sleeving

 

 

 

SS Flexible Conduit

A flexible conduit provides maximum protection to lead from abrasion but cannot bend as sharply as stainless steel braid. Flexible conduits are also swaged in, thus providing the same benefit of not being pulled out of the heater. 

 

 

End Seal Options

Teflon Seal

Teflon seal is used where effective sealing is required against moisture and oil contamination. Teflon lead wire is used in conjunction with a Teflon seal to provide an effective barrier.

Teflon Seal

Epoxy Seal

Epoxy potting forms a good moisture seal with more mechanical strength than a silicon rubber seal. Regular Epoxy is rated at 350°F (177°C) and epoxylite is rated at 600°F (316°C).

 

Silicon Rubber Seal

High-temperature silicon rubber seal in conjunction with silicon rubber lead wires provides an effective moisture seal up to 400°F (200°C). It is the most impervious seal of all the other moisture seals.

 

 

Fitting Options

Single-Ended NPT Fitting

Fittings are available in brass and stainless steel. Brass fittings are brazed on and stainless steel fittings can be either brazed or welded on.

 

 

 

Double Ended NPT Fitting

Double-ended fittings are normally used when it is desirable to mount a box on an immersion heater. Fittings are available in stainless steel and brass.

 

 

Flanges

Flanges are used to hold the heater in place preventing heaters from being backed out during operation. These flanges are welded on the lead end of the heater. They are 1/16” thick.

 

 

Other Options

Post Terminal

Post terminals are used in applications where easy lead replacement is desirable

 

 

 

Bent Hot Rod

Heaters can be bent at any angle from 10°C to 120°C. Heaters are bent at the unheated section. The option of bending is available in most of the heaters.

 

 

Double Ended

Hot rods are also available with electrical termination on each end. Heaters can be made with lead wire, straight pins, or screw terminals.
