Certification Standards

ATEX, IECEx, PESO, and UL 60079

Gasket Material

High-temperature, oil-resistant Neoprene or Silicone O-ring

Surface Treatment

Epoxy powder coated, RAL 7035 (Light Grey) or electropolished finish

Impact Resistance

IK10 mechanical impact rating

Earthing/Grounding

Internal and external SS316 earth studs (M6/M10)

Cable Entry Openings

Metric (M20 to M100) or NPT (1/2″ to 4″) threaded entries customized to layout

Locking Mechanism

Captive SS316 hex-head bolts or heavy-duty padlocking hinges

Internal Mounting Plate

Adjustable-depth galvanized steel or SS316 chassis plate

Window Options

Optional thermally toughened, borosilicate glass inspection windows

Technical Advantages

By utilizing high-grade copper-free alloys and CNC-machined flame paths, our enclosures offer superior structural integrity and precise tolerance retention under pressure. The integrated, multi-point isolation design eliminates the risk of environmental ingress, dramatically lowering failure rates of internal switchgear in high-vibration drilling environments.

Industry Applications

Offshore Drilling Platforms

Provides robust protection for critical power distribution blocks and telemetry systems against highly corrosive salt spray and volatile hydrocarbon gases.

Onshore Refineries & Petrochemical Plants

Safeguards complex automation modules, remote I/O panels, and motor starters situated near high-temperature distillation and cracking units.

LNG Bunkering & Storage Terminals

Ensures safe deployment of monitoring instrumentation and cryogenic control systems handling highly combustible liquid natural gas vapors.

FPSO (Floating Production Storage & Offloading) Vessels

Optimizes space and weight constraints on vessels while delivering certified Ex d protection for high-voltage marine switchgear assemblies.

Cross-Country Pipeline Compressor Stations

Houses localized control panels and valve actuators along remote pipelines, enduring severe outdoor weathering and heavy ambient vibration.

Mud Logging & Wellhead Control Systems

Protects sensitive sensory instruments and data logging machinery directly at the wellhead where drilling fluids and gas pockets pose constant risk.

Having Doubts? Our FAQ

What is the difference between Ex d and Ex e enclosures, and how does Frigate comply?

Ex d (Flameproof) enclosures are designed to contain an internal explosion and cool the escaping gases before they ignite the external environment. Ex e (Increased Safety) focuses on preventing sparks or excessive heat generation entirely. Frigate manufactures both types, fully certified to ATEX and IECEx standards, to suit your specific zone applications.

Can Frigate customize cable entries and drilling patterns for these enclosures?

Yes. We offer fully customized CNC machining for metric or NPT cable entries, breathers, and drain valves on any face of the enclosure. All custom machining is performed factory-side to preserve the certified flameproof path and maintain IP66/67 ratings.

How do your enclosures handle corrosive offshore marine environments?

Our enclosures utilize marine-grade, copper-free aluminum or SS316L stainless steel combined with high-grade epoxy powder coatings. This offers exceptional resistance against salt spray, sour gas (H2S), and chemical washing, maximizing the equipment’s lifespan.

What documentation and certifications are provided with each shipment?

Every enclosure shipped by Frigate comes with a comprehensive documentation package. This includes ATEX/IECEx/PESO compliance certificates, routine pressure test reports, material traceability certificates (MTRs), and standard installation/maintenance manuals.

Do you support custom dimensions, or are we limited to standard catalog sizes?

While we maintain a large inventory of standard modular sizes for rapid deployment, Frigate specializes in custom-engineered casting and fabrication. Our engineering team will review your internal layout, thermal load, and spatial constraints to draft a custom solution.
