Convert process heat into power supply for autonomous Iot

Power up your IoT devices with self-generated electricity

The SensEver Alfa is an autonomous power supply that converts the heat difference between a machine or pipe and its environment into a regulated voltage that can be chosen from 1.5-9 V to fit most available Industrial Internet of Things (IoT) devices.

With no moving parts and fully encapsulated electronics, the Sensever Alfa resists vibrations, moisture, explosive gases and standard industrial cleaning processes.

As an entirely self-contained, self-powering device, the Alfa easily outperforms all currently available battery lifetimes, making it a promising maintenance-free alternative for monitoring systems.

Improve safety with self-powered hot surface indicator

SensEver HSI is an autonomous stand-alone device that flashes visual warning when the temperature of the surface reaches the pre-set threshold.

In a pharmaceutical production site, 15% of personal injuries happen from unintended contact with hot pipes or machine parts during service tasks.

Sustainable power

The CO2 footprint of the production of a product based on thermal energy harvesting is in many industrial cases lower than a cable installation and a battery solution that requires several battery changes during its lifetime.

On top of the economic advantages, TEGnology also provides a solution that actively reduces your company’s environmental footprint.
