For decades, "Calrod" has been a dominant name in electric resistance heating. Known for reliability and longevity, these sheathed tubular heaters are widely used in appliances like ovens, dishwashers, coffee makers, and industrial equipment. However, with rising supply chain pressures and the need for more flexible, budget-conscious solutions, many OEMs and maintenance teams are now asking: Is there a true alternative?
The answer is yes – and our tubular heaters deliver exactly that.
Direct Replacement Without Compromise
Our tubular heaters are engineered as direct performance substitutes for Calrod™-style heating elements. We don't just copy the shape – we match the key performance metrics: watt density, response time, dielectric strength, and service life. Using high-grade Incoloy®, stainless steel (304/321/316L), or copper sheathing, our products withstand oxidation, corrosion, and thermal fatigue in environments up to 1200°F (650°C+), depending on specification.
Independent lab tests and field data show our tubular heaters achieve comparable – often identical – cycle life under rated loads. That means no redesign, no safety downgrade, and no sacrifice in heating efficiency.
Why Pay More for a Name?
The largest differentiator? Price. Our cost structure is lean, without the legacy overhead of tier-one branded divisions. You typically save 20–35% per unit for equivalent power ratings and sheath materials. Savings multiply quickly when scaled to production runs or facility-wide retrofits.
Fully Customizable – We Bend to Your Needs
Unlike many "standard-only" suppliers, we excel at customization. Our engineering team works directly with yours to produce heaters in virtually any single- or double-ended configuration:
- Shape: Round, flat, triangular, or custom-formed to fit tight appliance cavities or tank flanges.
- Terminations: Screw terminals, flexible leads, spade lugs, or high-temperature connectors.
- Mountings: Compression fittings, NPT threads, flanges, or brackets – we integrate per your drawing.
- Wattage & Voltage: From 100W to 6kW+, 12V to 480V, single- or three-phase.
- Lead length & sleeving: Fiberglass, silicone rubber, or Teflon™ over lead wires for moisture/abrasion protection.
Quality You Can Verify
We maintain ISO 9001 manufacturing and test every heater for:
- Dielectric withstand (1000–1800V)
- Insulation resistance (≥10 MΩ cold)
- Leakage current (≤0.5mA at rated voltage)
- Mechanical fit check on your provided fixture (available upon request)
Conclusion
You don't need a branded name to get branded-level performance. Our tubular heaters deliver the same heat, same reliability, and same safety – but at a lower price and with unlimited customization. Whether you need 50 units for a maintenance kit or 5000 for an OEM production line, we're ready to quote.
