Warom explosion proof control station

Warom's explosion-proof operating column, also known as an explosion-proof operating box or explosion-proof control station, is a non-electrical device integrated into explosive environments. Its core function is to provide on-site operators with a safe and reliable interface for remotely controlling motors, valves, lighting, and other equipment, including starting, stopping, and signaling. Its rugged casing effectively isolates potential internal sparks and high temperatures, preventing them from igniting surrounding explosive gases or dust.

I. Main Features and Advantages

High-Level Explosion-Proof Performance:

A variety of explosion-proof types are available, including flameproof (d), increased safety (e), and composite (de).

Compliant with Chinese GB3836, European ATEX, and international IECEx standards, it is suitable for use in hazardous locations such as Zones 1, 2, 21, and 22.

Rugged and Durable Construction:

Casing materials: Typically made of high-strength cast aluminum alloy, stainless steel (304, 316L), or engineering plastics, it offers excellent impact and corrosion resistance, making it suitable for use in harsh environments such as offshore platforms and chemical plants.

Sealing Performance: Silicone rubber seals are used, typically achieving IP65/IP66/IP67 protection levels, effectively preventing dust and water intrusion.

Flexible and Diverse Configurations:

Operating Elements: Available with explosion-proof pushbuttons (illuminated/non-illuminated, latching/reset), selector switches, potentiometers, key switches, emergency stop buttons, and more.

Indicator Elements: Available with signal lights (red, green, yellow, blue, and other colors), voltmeters, ammeters, digital displays, and more.

Mounting Options: Supports pole-mount (ground-mount), wall-mount, and guardrail-mount installations to meet diverse site requirements.

Safety and Reliability:

Internal components are from renowned brands, ensuring responsive and reliable operation.

Emergency stop buttons typically feature a striking red mushroom-shaped design and a self-locking function, ensuring rapid power disconnection in an emergency.

All wiring terminals are secure and clearly labeled.

Easy Installation and Maintenance:

The main chamber typically features a door or lid design, offering easy access and a spacious interior for convenient wiring and maintenance.

II. Series Classification by Main Structure

This is the most intuitive classification method. Warom's operating columns are mainly divided into the following series:

1. BZC Series Explosion-Proof Operating Columns

This is Warom's most classic and common operating column series, covering the vast majority of application scenarios.

Features: Sturdy structure, flexible configuration, and high protection level.

Material: Primarily made of high-strength cast aluminum alloy, with stainless steel (such as the BZC-E series) and engineering plastic (such as the BZC-D series) options also available.

Mounting: Supports column and wall mounting.

Typical Model Examples:

BZC51-KA: Basic model, cast aluminum housing, built-in pushbutton and signal light.

BZC53-E: Stainless steel, suitable for more corrosive environments.

BZC54-D: Engineering plastic (polycarbonate) housing, lightweight and corrosion-resistant.

2. BZC80 Series Multi-Function Explosion-Proof Operating Columns

This series generally features more modern design and functionality, a higher degree of modularity, and a more refined appearance.

Features: Modular design, easier installation and maintenance, streamlined appearance, and excellent sealing performance.

Material: Mostly die-cast aluminum alloy or stainless steel.

Typical Model Examples:

BZC8050: Standard multi-function model.

BZC8050/Ex: Model that meets specific explosion-proof standards.

3. LB Series Explosion-Proof Operating Boxes (Vertical/Large)

This series generally refers to operating boxes with larger size and more spacious interior space, accommodating more electrical components such as circuit breakers, contactors, and inverters.

Features: Large internal volume, can be used as a small explosion-proof distribution box, and highly integrated functions.

Applications: Suitable for complex applications requiring control, protection, and display functions within a single device.

Typical Model Examples:

LB2551: Large vertical operating column.

4. Other Specialty Series

Explosion-proof Instrument Control Columns: Integrated control columns with digital displays, thermostats, and other instruments.

Marine Explosion-proof Control Columns: Meet marine standards and offer enhanced resistance to salt spray and vibration.
