Why use thermal oil instead of steam?

Thermal oil reaches 300 °C or more at near-atmospheric pressure, so you avoid high-pressure vessel duty, water treatment, blowdown losses and freezing risk. It suits precise, high-temperature process heating.

How often should thermal fluid be tested?

At least annually, and every six months on high-duty plant. Testing is far cheaper than a coil failure caused by degraded fluid.

Can you replace the fluid without a long shutdown?

Yes — a planned flush and change-out is usually a two- to three-day job with the correct flushing fluid and disposal arrangements.

Troubleshooting

Common thermal oil boiler faults in Chamdor

Fluid degradation and carbon build-up+
Likely causes
- Film temperature exceeding the fluid limit
- Low flow through the coil
- Fluid past its service life or contaminated
What to check
Send a fluid sample for analysis — viscosity, flash point, carbon residue and low boilers tell the full story.
When to call us
As soon as analysis flags degradation; carbon deposits cause hot spots and coil failure.
Loss of process temperature+
Likely causes
- Fouled coil surfaces
- Pump wear or cavitation
- Air or moisture in the fluid circuit
What to check
Compare pump differential pressure and flow with commissioning data.
When to call us
If venting and a pump check don't restore temperature, the coil likely needs cleaning.
Fluid leaks and smoking joints+
Likely causes
- Failed flange gaskets under thermal cycling
- Pump seal wear
- Coil pinhole from internal corrosion
What to check
Inspect flanges and pump seals when hot — hot thermal oil leaks are a serious fire risk.
When to call us
Immediately — shut down and call out; thermal oil above its flash point ignites readily.
