Therm-O-Signal 7-H-44: the only temperature-indicating paint that changes color at 280 °C

Therm-O-Signal 7-H-44 was developed with one clear goal: to make dangerous overheating visible before it becomes an incident. It is currently the only safety coating in its class that changes color at 280 °C, allowing operators to recognize abnormal heat buildup in a timely manner on, for example, reactors, pipelines, and other critical process equipment.

What makes Therm-O-Signal 7-H-44 so valuable in petrochemical processes?

Provides a clear, visual indication from 280 °C.
Helps detect a wide range of problems in critical processes (insulation damage, local contamination, flow issues, cooling failure).
Adds an extra layer of safety alongside instrumentation and alarm systems, directly on the steel surface.

Interested to learn how this fits into your safety concept?
