Precision Thermal Dynamics for Global Industry & OEMs
Engineered heating solutions with a 4,800m² manufacturing footprint. Verified thermal consistency and material traceability.
Who We Are
Elekheat is not a generalist trading company; we are a dedicated manufacturer of thermal energy conversion systems. Since its establishment in 1997, we have focused exclusively on the thermodynamics of resistance heating.
We bridge the gap between material science and functional engineering. By controlling the entire manufacturing chain—from resistance wire winding to MgO compaction—we ensure strict dielectric and thermal benchmarks.
| Metric | Specification |
|---|---|
| Facility Size | 4,800 m² (Owned) |
| Core Competency | High-Watt Density Cartridge, Tubular & Immersion Heaters |
| Quality System | ISO 9001:2015 Certified |
| Market Reach | 30+ Countries (EU, North America, Asia) |
Engineering Your Vision into Heat
Our engineering methodology relies on predictive modeling and rigorous material selection. We utilize Computational Fluid Dynamics (CFD) to predict sheath temperatures and prevent carbonization.

Material Transparency & Selection Standards
| Component | Standard Material Grade | Engineering Logic (Mechanism → Benefit) |
|---|---|---|
| Resistance Wire | NiCr 80/20 | Prevents oxidation at temps >1000°C, ensuring stable resistance over 10,000+ cycles. |
| Insulation | High-Purity MgO (>99%) | Maximizes thermal conductivity while maintaining Dielectric Strength >2000V. |
| Sheath | Incoloy 800 / 840 | Superior resistance to carburization compared to SS304. |
| Sealing | RTV Silicone / Epoxy | Hermetic sealing prevents moisture ingress (hygroscopic action). |
Safety & Quality Standards
In high-voltage heating applications, quality is a safety mandate. Elekheat integrates testing into the production line (in-process) rather than relying solely on post-production sampling.
Engineer’s Note:
“A heater may work upon delivery, but its insulation resistance (IR) after thermal cycling defines its true quality.”
Validation Protocol (Every Batch)
Dielectric Withstand (Hi-Pot): 1500V – 2500V / 1s (No breakdown)
Leakage Current: < 0.5 mA at operating temp (IEC 60335 compliant)
Insulation Resistance: > 500 MΩ at 500VDC (Cold state)
X-Ray Analysis: Random sampling for coil centrality.
State-of-the-Art Manufacturing
Consistency requires automation. We have transitioned to a fully automated workflow to guarantee a Cpk > 1.33.
Automated CNC Winding
Mechanism: Precise pitch control.
Benefit: Eliminates “hot spots” caused by uneven wire spacing, extending element life.
12-Station Rolling Mill
Mechanism: Reduces tube diameter to compact MgO to 3.2 g/cm³.
Benefit: Doubles thermal conductivity and dielectric strength compared to loose-fill heaters.
Laser Welding
Mechanism: Flange and end-cap attachment.
Benefit: Creates a metallurgical bond without introducing filler materials that could corrode.
