Waste Heat-enabled IoT Monitoring for Predictive Maintenance
The arrival of industrial Internet of Things (IoT) technology has enabled real-time tracking and remote monitoring of key operational parameters like vibration and temperature, for plant maintenance.
However, the mass deployment of IIoT using wired networks for power supply is capital intensive and not flexible.
Likewise, deployment using battery-powered wireless network (IoT) has low wireless coverage due to battery energy storage limitations and requirements for complex and costly wireless infrastructure, i.e., gateway, etc. If lithium battery is used, it is not environment friendly and not suitable for explosive environments and heat-intensity facilities.
To circumvent this power supply issue, waste heat recovery or energy harvesting is proposed.
In a report published by the US Department of Energy, an estimated 20% to 50% of industrial energy input is lost as waste heat in the form of hot exhaust gases, and heat lost from hot equipment surfaces and heated products. Recovering waste heat losses generate cost savings, reduces environmental impact and improves productivity.
Offgrid Energy (S) Pte Ltd is pleased to be the distributor for a key innovator in net zero autonomous IoT wireless monitoring using waste heat for predictive maintenance. The standard equipment consists of a vibration sensor or temperature sensor, thermoelectric generator, and a wireless IIOT device, and proprietary dashboard for dynamic reporting.

Value propositions include:
- Decarbonisation
- 96 % reduction in carbon emissions, water, heat and energy consumption, and
- Estimated reduction of up to 400Kg CO2eq per device annually.
- Environmentally friendly
- Suitable for explosive environments ATEX / IECEx and heat intensive facilities.
- Savings in equipment acquisition (CAPEX)
- Savings in wireless infrastructure (CAPEX)
- Reduction in operating expense (OPEX)
- No battery replacements and no process stop due to maintenance activities.
Get in touch with us if you wish to know more about how to use waste heat for net zero autonomous IoT wireless monitoring and predictive maintenance, and to decarbonise your business operations.
