Is High Maintenance Cost a Heater Problem… or a Design Problem?

Many industries accept frequent heater replacement as a normal operating expense. But should they?

If your maintenance team is replacing heaters every few months, shutting down production for repairs, or constantly troubleshooting heating issues, the real problem may not be the heater—it may be the system design.

High maintenance costs are often the result of:\

Incorrect heater selection

Excessive watt density

Corrosion and scaling

Oxidation at high temperatures

Poor terminal design

Improper installation

Lack of preventive maintenance

Replacing failed heaters without identifying the root cause

The hidden costs extend far beyond the price of a new heater:

- Production downtime
- Emergency maintenance
- Spare parts inventory
- Overtime labor
- Product quality losses
- Reduced equipment availability

Before ordering another replacement heater, ask:

- Why did the previous heater fail?
- Can the heater design be improved?
- Is a different material or watt density required?
- Can maintenance intervals be extended?
- What is the total cost of ownership—not just the purchase price?

At Asanjo, we believe the most economical heater isn't the cheapest one—it's the one that delivers the lowest lifetime maintenance cost. By understanding your process and engineering the right heating solution, we help reduce failures, extend heater life, and improve plant reliability.

Don't measure the cost of a heater by its purchase price. Measure it by the downtime, maintenance, and production losses it prevents.

Is Tube Oxidation Above 1000°C Reducing Your Furnace Reliability?

Radiant tubes are designed to withstand extreme temperatures, but operating above 1000°C presents a significant challenge—oxidation.

Over time, continuous exposure to high temperatures causes the tube surface to react with oxygen, forming oxide layers. While some oxidation is expected, excessive oxidation gradually weakens the tube wall, reduces heat transfer efficiency, and shortens the service life of the radiant tube.

The warning signs include:

Excessive surface scaling

Tube wall thinning

Reduced heating efficiency

Increased fuel or power consumption

Tube distortion or sagging

Unexpected tube failure and furnace shutdown

Many users replace oxidized tubes without investigating the root cause. In many cases, the problem lies in the operating conditions rather than the tube itself.

Before replacing a radiant tube, ask:

Is the tube material suitable for continuous operation above 1000°C?

Is the furnace atmosphere oxidizing, carburizing, or reducing?

Is the heat input creating localized overheating?

Are the burners or heating elements producing uniform temperature?

Would a higher-grade alloy such as Kanthal APM, APMT, or another high-temperature alloy improve service life?

At Asanjo, we don't simply replace radiant tubes—we evaluate the furnace temperature, atmosphere, and operating conditions to recommend the most suitable material and design. The right tube can significantly improve furnace reliability, reduce maintenance frequency, and lower the total cost of ownership.

A radiant tube doesn't fail because it reaches 1000°C—it fails when the material is not matched to the furnace conditions. Choosing the right alloy is the key to long-term performance.

Why Do Industrial Heaters Burn Out Frequently?

When an industrial heater fails, the heater itself is often blamed. However, in many cases, the heater is only the victim—the real problem lies elsewhere.

Frequent heater burnout is commonly caused by excessive surface loading, scaling on the sheath, poor heat dissipation, dry firing, improper temperature control, voltage fluctuations, or selecting the wrong heater material for the application.

As deposits build up on the heater surface, heat transfer efficiency drops significantly. The element temperature rises beyond its design limit, leading to premature failure. Similarly, when a heater is exposed to air due to low liquid levels or poor circulation, localized overheating can occur within minutes.

The true cost of heater burnout is much greater than the replacement heater itself. Production downtime, emergency maintenance, lost output, and quality issues can quickly become far more expensive than the heater.

Rather than repeatedly replacing failed heaters, it is important to identify the root cause:

Is the watt density too high?

Is scaling reducing heat transfer?

Is the sheath material suitable for the process?

Is adequate circulation available?

Are temperature controls functioning correctly?

The best heater is not the one with the lowest purchase price—it is the one that delivers reliable performance, maximum uptime, and the lowest total cost of ownership.

Is Temperature Overshoot Damaging Your Process and Your Heater?

Reaching the target temperature is important—but controlling it accurately is even more critical.

Temperature overshoot occurs when the process temperature rises above the desired set point before the controller can respond. While it may seem like a minor issue, repeated overshoots can reduce product quality, shorten heater life, and increase energy consumption.

In industrial furnaces, ovens, tanks, and process heating systems, temperature overshoot can lead to:

Product rejection due to overheating

Oxidation and reduced life of heating elements

Damage to heat-sensitive materials

Thermal stress on equipment

Unnecessary energy consumption

Longer stabilization time and reduced productivity

Many assume the temperature controller is at fault. In reality, the root cause may be:

- Heater wattage that is too high for the application
- Incorrect watt density
- Poor sensor location
- Improper PID tuning
- Slow process response
- Incorrect heater zoning or heat distribution

Before replacing heaters or controllers, ask:

- Is the heater correctly sized for the process?
- Is the temperature sensor positioned in the right location?
- Is the controller properly tuned?
- Is the heating load changing during operation?
- Does the process require staged or multi-zone heating?

At Asanjo, we believe reliable heating is not just about generating heat—it's about delivering the right amount of heat at the right time. By combining proper heater design with sound application engineering, temperature overshoot can be minimized, improving product quality, extending heater life, and reducing operating costs.

Precision heating isn't achieved by adding more power—it's achieved by applying the right power in the right way.

Why Argon Welding Is Mandatory for Kanthal Material
Argon welding provides an inert, oxygen-free environment during the welding process.

Benefits of Argon (TIG) Welding for Kanthal:

Prevents oxidation at the weld joint
Preserves alloy chemistry
Ensures uniform grain structure
Maintains electrical conductivity
Produces strong and ductile welds
Without Argon protection, the weld zone becomes the weakest link in the heating element.

Problems Caused by Improper Welding of Kanthal Material
Below are the major issues that occur when Kanthal material is welded without proper Argon shielding.

1. Oxidation and Porosity at the Weld Joint
2. Brittle Weld Zone and Cracking
3. Increased Electrical Resistance at Weld Area
4. Thermal Shock and Expansion Failures
5. Loss of Protective Aluminum Oxide Layer
6. Contamination from Incorrect Electrodes or Flux
7. Reduced Mechanical Strength at Operating Temperature
8. Safety and Operational Risks

Best Practices for Welding Kanthal Material

To ensure reliable performance, always follow these guidelines:
Use TIG welding with high-purity Argon gas
Maintain Argon shielding until weld cools
Avoid excessive heat input
Clean material thoroughly before welding
Use correct filler material (if required)
Ensure welding is done by trained professionals

Argon welding is not optional — it is essential for ensuring long service life, stable electrical performance, and safe operation of Kanthal heating elements.
If you want your industrial heating system to perform reliably, never compromise on Kanthal welding quality.
