We Engineer Safety Into Every Enclosure
Fifteen years of building explosion-proof electrical equipment for the oil, chemical, marine, and mining industries. Own foundry. Own CNC. Full third-party certification. MOQ starts at one unit.
A Focused Explosion-Proof Manufacturer, Not a Trading Company
ExCtrl is a factory-direct manufacturer of explosion-proof electrical equipment based in China. Since 2011 we’ve focused on one thing: engineering enclosures that keep hazardous-area installations safe across their service life.
We run our own aluminium alloy foundry and CNC machining lines. Every shell that leaves our floor is traceable to raw-material lot, machining record, and pressure-test result. When you buy from us, you’re not talking to a middleman.
In-House Enclosure Foundry
Aluminium alloy casting and CNC finishing under one roof. Full material traceability from ingot to shipped product. No outsourced shell risk.
Full Third-Party Certification
CNEx, ISO 9001, EMC, IECEx, IP66, WF2 marine, IIB and IIC gas groups. ATEX in progress. Every unit ships with certificate and test report.
Global Delivery, MOQ 1
Projects delivered to 30+ countries: Middle East, Southeast Asia, Europe, Latin America. Custom nameplates and cable entries as standard, not premium extras.
Every Certification You Need for Specification
Certifications are how procurement, engineering, and safety teams validate that our equipment can go into a project package. Here is what we currently hold, and what’s on the way.
CNEx
National explosion-proof product certification. Baseline requirement for hazardous-area installations in China.
ISO 9001
Certified quality management system. Every production and inspection step is documented and auditable.
EMC
Tested for electromagnetic emission and immunity. Safe operation alongside sensitive instrumentation and DCS equipment.
ATEX
ATEX Directive 2014/34/EU certification under active review. Target completion within the current fiscal year.
IP66
Dust-tight and protected against powerful water jets. Verified via in-house pressure and spray testing for every batch.
WF2 Coating
Salt-spray tested marine-grade corrosion protection. Standard on offshore and coastal project specifications.
IIB + IIC
Certified for both IIB (propane, ethylene) and IIC (hydrogen, acetylene) hazardous gas atmospheres. Zone 1 and Zone 2 approved.
Dust Ex
Zone 21 / 22 dust explosion protection. For grain, mining, chemical powder, and metal-processing environments.
Why Owning the Foundry Matters
Most explosion-proof suppliers outsource enclosure shells. We don’t. Running our own aluminium foundry and CNC line is how we control what enters the certification chain.
Five Steps Between Raw Material and Your Site
Every unit passes the same five-stage inspection sequence. Test records ship with each order alongside the certificate of conformity.
Incoming Inspection
Raw aluminium ingots and terminal components verified against material certificates and dimensional spec.
CNC Machining
Flame-path surfaces machined and gauged. Every enclosure logged with operator, machine, and dimensional record.
Assembly & Wiring
Terminals, gaskets, and cable entries assembled to drawing. Torque values recorded on every connection.
Pressure & IP Test
Ex d units pressure-tested to 1.5x reference pressure. IP66 spray and dust testing on 100% of enclosures.
Final & Packing
Nameplate verification, dielectric test, certificate matching, then export packing to project standard.
