Product Overview

This series of explosion-proof air conditioning units incorporates specialized explosion-proof design and processing technologies, offering a wide capacity range. Utilizing a complete set of high-quality, name-brand refrigeration components and precision engineering, the units ensure excellent overall performance, reliable operation, and low noise levels. They are widely applicable in explosive hazardous areas where flammable gases, vapors, or air mixtures of Groups IIA, IIB, IIC, and Temperature Classes T1 to T4 may be present, such as in scientific research, petroleum, chemical, pharmaceutical, processing, manufacturing, and biological industries, meeting environments with stringent temperature control requirements.

The products have passed China's National Explosion-proof Electrical Product Quality Supervision and Inspection, obtaining the required explosion-proof certification. They are also ATEX certified, complying with EU Directive 2014/34/EU and relevant EN standards. The series boasts an aesthetic appearance, rational design, and easy installation and maintenance. Featuring microprocessor control and digital display, they are user-friendly and exhibit stable performance.


Key Features

1. Advanced Explosion-Proof Technology, Safe & Reliable

Designed and manufactured with cutting-edge explosion-proof technology to ensure safe and stable operation in hazardous environments.

2. Concealed Installation, Saves Space & Enhances Aesthetics

Indoor unit is recessed into the ceiling with only the air vent visible, preserving interior layout and saving valuable floor space.

3. Flexible Air Distribution with Optional Fresh Air

Supports multi-vent air supply for even airflow; fresh air intake function improves indoor air quality. High static pressure models enable long-distance air delivery. Outdoor unit can be installed on rooftops, balconies, or outdoor racks for versatile placement.

4. Intelligent Control & Comprehensive Protection

Microprocessor-controlled for fast response and precise temperature regulation. Features multiple protection functions including overload, overcurrent, high pressure, waterproofing, reverse phase, and delayed start. Control panel clearly displays temperature, operational status, and mode settings.

5. Quiet Operation with Low-Noise Design

Equipped with explosion-proof low-noise fans, ensuring quiet and reliable performance suitable for noise-sensitive applications.

6. Simplified System, Lower Initial Investment

Compared to traditional central air conditioning, it eliminates the need for complex water systems and terminal units, significantly reducing upfront costs and maintenance requirements.
