Customization Capabilities (Tailored for Your Project)

As a specialized manufacturer, we don't just sell boxes; we provide engineered solutions:

1. Multi-Pump Logic: Automatic alternating control for dual-pump systems (Lead/Lag) to ensure balanced wear.

2. Remote Control: Dry contact terminals for PLC integration or remote DCS monitoring.

3. Entry Specifications: Customizable NPT, Metric, or G-thread entries with matched Ex-proof Cable Glands.

4. Component Brand Preference: We can integrate specified global brands for internal components.

Typical Applications

• Petrochemical: Oil transfer pump control stations.

• Water Treatment: Sewage and drainage pump systems in hazardous gas areas.

• Marine: Deck machinery and ventilation control on tankers/platforms.

• Industrial: Explosion-proof starters for mixers, conveyors, and blowers.
