Fully shielded facilities for testing, developing and operating sensitive defence electronics — electromagnetic isolation you can measure against.
Service information
Finex EMI/EMC shelters provide specialised, fully-shielded facilities for testing, development and operations of sensitive defence electronics and communications systems. They offer comprehensive electromagnetic isolation, enabling military-grade equipment development, qualification testing and secure operations in electromagnetically complex environments.
The shielding is the product. Multi-layer Faraday cage construction with continuous mesh and double-layer walls, multi-point grounding, RF-filtered bulkhead connectors on every penetration, and pyramidal absorber treatment inside the chamber so a measurement reflects the equipment rather than the room.
What we make
Any one of these can be contracted on its own, or the whole interior delivered under a single award against one drawing set and one schedule. Everything listed is manufactured, supplied and installed by us — not sub-let after award.
Susceptibility, emissions and acceptance testing in a controlled RF environment.
Classified development, secure operations and electronic warfare work.
Measurement chambers, satellite links, and how the facility grows.
Standards & compliance
Wording here is deliberate: we design and manufacture to these criteria.
Certificates held
The certificates from our register that apply to this work, each with its issuing body and certificate number. Nothing here is a claim we have not been audited for.
Certificates held Not what we design to — what we are audited and licensed for, with the certificate number on each.
Why Finex
More than 1,00,000 sq. ft. across two units near Nashik. The container modification, the structural welding, the fit-out and the finishing stay under our control instead of being sub-let after award.
Built on ISO container platforms, so a unit moves on the truck, rail and airlift chains a force already operates — no special handling equipment to procure alongside it.
Structure, shielding, power, climate control and interior fit-out on a single order, with one schedule and one name on the handover certificate.
We will tell you what is certified, what is built to a standard and what still needs testing, before you specify it. An awkward conversation early is cheaper than a rejected inspection.
FAQ
If yours is not here, ask — we would rather answer it properly.
The design target is over 90 dB across 10 Hz to 10 GHz, rising to over 100 dB in the 1 MHz – 10 GHz band. Achieved performance is verified per installation, and the verification report is part of the handover documentation.
Yes. The main and secondary chamber dimensions given are the standard configuration; chambers are built to the equipment envelope and the test standard you are working to. Modular expansion lets a facility scale later.
It can be. The shelter integrates network and spectrum analysers, signal generators, power meters, oscilloscopes and environmental monitoring, with automated test sequences and network-based remote control from an external laboratory. Tell us which standards you test to and we will scope the instrumentation against them.
Dedicated precision HVAC with independent backup holds ±2 °C and 45–55% RH, with continuous logging and alarms. Pneumatic isolators handle sub-1 Hz vibration and the acoustic environment stays under 50 dB(A).
Our plants are at Gut No. 243/1B, Pimpalnare, Dindori, Nashik, Maharashtra – 422004. We build there and deliver pan-India.
A tender number, a specification or a drawing set — we will confirm what we can build and by when, within two working days.
