About Us:

DEFT Industrial Automation was established on 20 November 2020 – and on 20 November 2026 we celebrate six years of “Let’s Automate Things.”

We specialise in PLC programming, SCADA development, panel design, field engineering and commissioning, providing end-to-end automation services from engineering to start-up. Over six years we have executed projects across India, Africa, Europe and the Gulf – from glass batching plants and gelatine process lines to SIL 3 steam and gas turbine control systems and seawater desalination plants.

Our team is organised into three departments – Field Service, Engineering & Development and Accounts & Admin – so every customer gets fast site support backed by strong engineering. We continue to grow our people, partnerships and product portfolio, driven by a vision to harness advanced technology, improve industrial efficiency and create a brighter future for our clients.
