CNWINNEX Explosion-Proof Air Conditioning Unit for Pressurized Rooms

1. Product Overview

The CNWINNEX explosion-proof Air Conditioning Unit is specially developed for high-risk explosive environments in petroleum, chemical, pharmaceutical and other industrial fields. It is professionally applicable to Zone 1 and Zone 2 hazardous areas with flammable and explosive gases, including instrument control rooms, analyzer rooms, laboratories, metering rooms and explosion-proof pressurized shelters.

Integrated with cooling, heating, dehumidification, ventilation and positive pressure maintenance functions, this all-in-one unit realizes comprehensive environmental regulation for hazardous indoor spaces. Adopting a compact and robust industrial structure, the unit features reliable explosion-proof performance and elegant appearance. The enclosure is available in SS304, SS316L stainless steel and powder-coated carbon steel with customizable configurations, adapting to corrosive, humid and harsh outdoor industrial working conditions.

2. Core Product Features

2.1 Multi-functional Integrated Control

The unit integrates five core functions: cooling, heating, dehumidification, fresh air ventilation and indoor positive pressure stabilization. It automatically adjusts operating modes according to ambient temperature, humidity and air pressure. By maintaining stable indoor positive pressure, it effectively prevents external flammable and explosive gases from entering the room, eliminating potential explosion risks and protecting internal instruments, equipment and operators.

2.2 Fully Automatic Unattended Operation

Equipped with an intelligent control system, the unit supports automatic restart after power recovery. It can restore preset operating status without manual operation, perfectly adapting to continuous industrial production and unattended working scenarios. With stable logic and high fault tolerance, it supports long-term uninterrupted operation and greatly reduces manual maintenance costs.

2.3 Intelligent Linkage & Expandable Communication

Reserved with standard RS485 communication interface (optional) for remote networking, centralized monitoring and system linkage. It can be connected with DCS, PLC and SCADA systems to realize remote parameter adjustment, mode switching and fault early warning. Built-in dry contact interfaces support fire linkage, air pressure interlock and fault alarm functions, building a complete industrial safety linkage system for smart factory management.

2.4 High-efficiency Heat Exchange & Durable Performance

The heat exchanger adopts high-performance internally threaded copper tubes combined with hydrophilic aluminum or copper fin sheets, processed by advanced mechanical tube expansion technology to maximize heat exchange efficiency and reduce energy consumption. The compressors and core components are scientifically matched and optimized, solving common industry problems such as insufficient cooling/dehumidifying capacity, frequent startup and high failure rates. It effectively extends the service life and ensures long-term stable operation.

2.5 Diversified Installation & Customization

With complete model specifications and a wide cooling capacity range, the unit meets environmental regulation requirements for explosion-proof rooms of different sizes and working conditions. It supports multiple installation types: vertical duct type, vertical wall-mounted type and horizontal duct type. Full private customization is available according to on-site space size, anti-corrosion grade, explosion-proof standard and functional demands.

2.6 Simple Maintenance & Cost-effective Operation

Adopting a modular structural design, the unit features regular internal layout and convenient disassembly, enabling easy inspection, cleaning and daily maintenance. Compact in size and elegant in industrial appearance, it occupies less space and fits well with various explosion-proof workshops and control room layouts.

3. Application Scope

Widely used in petroleum refining, fine chemical, pharmaceutical, energy storage, oil and gas industries. Suitable for Zone 1 / Zone 2 explosive gas hazardous areas, including explosion-proof instrument control rooms, analysis rooms, precision laboratories, metering rooms, pressurized shelters and skid-mounted explosion-proof equipment rooms.
