CNWINNEX Explosion-Proof Screw Air-Cooled Chiller (Heat Pump) | Explosion-Proof Chiller for Petrochemical & Chemical Industries

CNWINNEX Explosion-Proof Screw Air-Cooled Chiller (Heat Pump) | Explosion-Proof Chiller for Petrochemical & Chemical Industries

The CNWINNEX explosion-proof screw air-cooled chiller (heat pump) is designed and manufactured in strict compliance with the EN 60079 series explosion protection standards and conforms to ATEX Directive 2014/34/EU, featuring reliable quality and superior explosion-proof performance. The unit is mainly suitable for the petroleum, chemical, electric power, military and pharmaceutical industries, and is applied in hazardous areas of Zone 1 and Zone 2 where explosive atmospheres formed by flammable gases or vapours of Group ⅡA, ⅡB, ⅡC and temperature classes T1~T4 mixed with air may exist. Explosion-proof marking: Ex db mb IIC T4 Gb, suitable for Zone 1 and Zone 2 explosive hazardous areas. With advanced twin screw compression technology, intelligent control system and reliable explosion-proof design, the unit provides efficient, stable and energy-saving chilled (or hot) water supply for high-hazard industrial sites.

Key Product Advantages

●        Multiple structural forms: Available in modular and integral types with elegant appearance, compact structure and small footprint, easy to install and maintain

●        Intelligent control: Microcomputer-based intelligent control automatically adjusts compressor output energy according to load changes, maintaining efficient working status at all times

●        Multiple safety protection: Phase sequence, phase loss, high/low pressure, insufficient water flow, chilled water anti-freezing, compressor and motor overload, compressor over-temperature and other multiple protection functions ensure reliable unit operation

●        High-efficiency compressor unit: Modular units adopt well-known brand scroll compressors with reliable performance, low noise and low vibration; integral units adopt high-IPLV twin screw compressors with 5:6 asymmetric rotor profile, high volumetric efficiency and unloading capacity control device, achieving multi-stage capacity regulation and higher operating efficiency

●        Quality core components: Main components adopt well-known domestic and international brand products with superior performance, ensuring more stable operation and better performance; internally threaded copper tubes deliver high heat transfer efficiency

●        Precise energy-saving control: Multi-stage capacity regulation provides more accurate chilled water temperature control and more energy-efficient operation

●        Quality anti-corrosion housing: Cabinet made of cold-rolled steel with plastic spraying for strong corrosion resistance and elegant appearance; panel inner walls are lined with sound-insulating and heat-insulating rubber-plastic material to reduce cooling loss; open structure design facilitates disassembly, maintenance and servicing

Typical Applications
