Our Cartridge Heaters
High-Density Cartridge Heaters
Definition: Designed for rapid heat transfer with high wattage per unit area.
Power Density: ≥100 W/in² (≥15.5 W/cm²).
Voltage: 120V, 240V, or custom.
Materials: Durable alloys (e.g., Incoloy sheath) to withstand thermal stress.
Applications: Injection molding, die casting, 3D printers.
Situations requiring fast heat-up times (<5 minutes).
Low-Density Cartridge Heaters
Definition: Optimized for steady, continuous heating with lower wattage distribution.
Power Density: ≤50 W/in² (≤7.75 W/cm²).
Voltage: Lower voltage options for delicate applications.
Materials: Stainless steel (SS304/SS316) for corrosion resistance.
Applications: Food processing, packaging machinery, medical equipment.
Long-duration processes require stable temperatures.
Metric Cartridge Heaters
Dimensions: Diameter: 4mm–25mm (common: 6mm, 8mm, 10mm).
Length: 20mm–500mm (standard: 40mm, 80mm, 120mm).
Hole Tolerance: Diameter ±0.01–0.02mm (tight fit for efficiency).
Regions: Widely used in Europe, Asia, and ISO-compliant industries.
Example: 8mm diameter × 60mm length, 400W, 240V.
Imperial (Inch-Size) Cartridge Heaters
Diameter: 1/8″–1″ (common: 1/4″, 3/8″, 1/2″).
Length: 1″–12″ (standard: 2″, 4″, 6″).
Hole Tolerance: ±0.001″–0.003″ for optimal thermal contact.
Regions: Predominant in North America and legacy machinery.
Example: 0.375″ diameter × 4″ length, 500W, 120V.
Immersion Cartridge Heaters
Definition: Designed to heat liquids or gases by direct immersion.
Power Density: 30–100 W/in² (4.65–15.5 W/cm²), depending on fluid type.
Materials: Corrosion-resistant sheath (SS316, Incoloy, titanium).
Safety Features: Double sealing, waterproof terminals, grounded elements.
Applications: Boilers, oil tanks, chemical processing, water heating.
Micro Cartridge Heaters
Definition: Ultra-compact heaters for confined spaces or precision heating.
Diameter: 1–4 mm (metric) or 0.04″–0.16″ (imperial).
Voltage: 12V–48V (low-voltage for safety in sensitive systems).
Materials: Inconel sheath for high heat in small sizes.
Applications: Medical devices, semiconductor tools, aerospace sensors
Bolt-On Cartridge Heaters
Definition: Integrated with mounting flanges/brackets for easy installation.
Power Density: Medium (50–80 W/in² / 7.75–12.4 W/cm²).
Mounting: M4–M8 bolts or 1/4″–3/8″ threaded flanges.
Shape: Cylindrical or flat-faced for surface contact.
Applications: Plastic extrusion barrels, industrial ovens, HVAC systems.
Rectangular Cartridge Heaters
Definition: Flat, block-shaped heaters for uniform heat distribution.
Dimensions: 5x10mm–20x50mm (metric) or 0.2″x0.4″–0.8″x2″(imperial).
Materials: Copper or brass housing for heat spreading.
Applications: Flat-press molds, packaging seals, lab equipment platens.
Custom Cartridge Heaters
Definition: Bespoke designs for unique applications.
Specifications:
Tailored Features: Non-standard diameters, bent shapes, multi-zone coils.
Materials: Exotic alloys (Hastelloy, ceramic coatings) for extreme conditions.
Voltage: Custom wattage/voltage configurations (e.g., 480V, three-phase).
