TYPX Positive Pressure Explosion-proof Control Cabinet

TYPX cabinet maintains internal micro positive pressure via clean purge gas to block external flammable mixture, safer than traditional flameproof design above national standard. Fully pneumatic without power supply, fits all hazardous zones except Zone0, with pressure monitor and auto purge for low-temperature corrosive chemical production.

Explosion-proof Junction Box

Junction boxes transfer instrument and power cables in hazardous zones. Thick flameproof shell seals cable glands to avoid spark ignition. Stainless steel, plastic and carbon steel options with multi-size glands and IP65 rating against dust and rain, fit offshore, underground and powder workshops.

How to Choose Positive Pressure Explosion Proof Cabinets for Zone1 Plants? Tovent Practical Guide

Many chemical Zone1 factories make mistakes when buying explosion-proof cabinets. Ordinary flameproof cabinets fail to handle continuous volatile gas, leading to seal damage and short circuits caused by condensed water after long-term use. Tovent TYPX positive pressure cabinet adopts fully pneumatic purge design without external control power. Full 316L stainless steel shell adapts to high-corrosion media like methanol and ethylene. Equipped with CCC certificate and high-precision pressure sensor, it monitors internal micro positive pressure and triggers alarm automatically to stop flammable gas penetration, ideal for continuous refinery and coal chemical production.

Compared with generic positive pressure cabinets, Tovent supports full non-standard customization of circuit loops, heating insulation and remote alarm. Self-developed pneumatic timer achieves 0-99min precise purge timing, recognized as domestically leading technology.

Multi-loop Power Distribution Solution of Explosion Proof Boxes for Coal Chemical Plants

Coal-to-olefin plants contain methane and coal dust with numerous power equipment and complex distribution loops. Ordinary boxes have limited loops and poor protection, overheat under long operation. Tovent power distribution box supports up to 12 branches with 200A max current, carbon steel/stainless steel optional, Ex IIB/IIC for Zone1/2 coal chemical areas. Dual overload & short-circuit protection provides safe unified power for compressors, pumps and fans.

For high-dust & corrosive coal chemical conditions, custom thick dust-proof seals and outdoor rain covers for pipe gallery installation. Imported Siemens & ABB components reduce failure rates. Tovent full production line cuts bulk order delivery time by 30%, offering overall explosion-proof system design. Major coal chemical enterprises like CHN Energy and Yanchang Petroleum place long-term orders, equipment annual failure rate far below industry average.
