Intelligent heat stress prevention
An industrial wearable that monitors heat-stroke risk in real time and alerts via light, sound and vibration before it becomes a workplace accident.
Heat stress is a real occupational risk
Heat stroke and heat stress affect workers exposed to high temperatures, whether outdoors (construction, agriculture, mining, oil & gas) or indoors with industrial heat (plants, warehouses, logistics). It is a recognized cause of sick leave, lost productivity and, in the most serious cases, workplace accidents. Its prevention is increasingly part of large companies' safety policies, regulatory compliance and corporate social responsibility.
Knowing the signs can save a life
Heat stroke doesn't appear suddenly: the body goes through progressive phases. Recognizing them in time makes the difference.
Multi-sensory alerts, easy to understand
ThermaSafe translates ambient and skin temperature data into a clear, actionable warning, even for workers without technical training and wearing PPE (helmets, ear protection).
Continuous monitoring
Ambient and skin temperature sensors assessing thermal risk in real time throughout the shift.
Tiered alerts
Traffic-light system (green–amber–red) to identify the risk level at a glance, with no technical training required.
Multi-sensory alert
Light, sound (~70 dB) and vibration combined, so the alert gets through even with ambient noise or hearing protection.
Rugged design
IP67 casing and ventilated silicone strap, built for extended use on site, in-plant or outdoors.
Safety programs
Designed to integrate into large companies' safety policies: reduced sick leave, regulatory compliance and worker care.
Long-lasting battery life
Up to 90 days of battery life (8 h/day of use) on a single charge, minimizing maintenance across large fleets.
A traffic light that acts before the risk does
The LED indicator changes color according to the detected thermal risk level, combining visual, audible and haptic warnings at the most critical level.

Green — Normal operation
Charging and correct-operation indicator. The green light blinks periodically in normal mode.

Amber — Elevated ambient temperature
Blinking amber light for 1 minute as a preventive warning when ambient temperature reaches or exceeds 42ºC.

Red — Heat-stroke risk
Blinking red light, buzzer and vibration for 1 minute under continued risk, when the worker's body temperature exceeds 37.8ºC. Highest priority for reaction.
