What is documented
Every claim on this site traces to a document you can open. Where we hold no document, the page says so rather than filling the gap.

- Electrical testing station at the works, including a 5 kV high-voltage breakdown testerHVTD-5Evidences that the equipment exists and is in use. No calibration certificate, test report or type test is held, and none is implied.
- Certificate of compliance ICM-CE-25032228, issued by ICMBV LimitedICM-CE-25032228ICMBV Limited, 71-75 Shelton Street, London WC2H 9JQA third-party certificate of compliance, dated 14 August 2025 and valid to 13 August 2028 — not an EU Declaration of Conformity, and it names no Notified Body number. The four directives it cites (73/23/EEC, 92/59/EEC, 98/37/EEC and 93/42/EEC, the medical devices directive) have all been repealed, and a fifth, 59/336/EEC, does not exist. The certificate itself states that it rests on a single sample, does not imply assessment of whole production, and that the CE mark may be applied only under the manufacturer's own declaration of conformity. It is offered as a document on file, and no claim of current EU conformity is made from it anywhere on this site.Open document

Built around the requirement
Engineering support before procurement, manufacture and installation — not only after a specification exists.
Have a rating, drawing, load schedule, site condition or electrical problem? We review the requirement, define the engineering scope and route it to the right solution.

How a requirement becomes plant
01
Requirement
A rating, a drawing, a load schedule, a site condition or a problem. Whatever you have.
02
Engineering review
We read it, ask what is missing, and define the engineering scope before anything is quoted.
03
Approval
General arrangement and schematic issued for your approval before manufacture begins.
04
Build, test, handover
Manufactured and tested at Faridabad, installed and commissioned under the Delhi licence, documentation handed over.
At the works
Winding, fabrication, assembly and works testing, with the plant available at Faridabad.
SHOT NEEDED
Industries served
An industry appears here only when there is a real installation behind it. We hold a photograph of AMF and DG control panels installed and commissioned on site, and no project record to describe it, so this section stays empty until verified project references exist.
Send the requirement
Send the rating, the single line diagram and the site. That is enough for a firm quotation — an enquiry without them gets a phone call asking for them.
