Ceiling-mounted Explosion-proof Air Conditioner of Guangdong Yujingfeng
Product Description
Ultra-slim Body Design
The indoor unit features an ultra-slim design with a thickness of only 245mm. It occupies minimal ceiling space, greatly increasing the net height of the indoor unit and avoiding the sense of depression caused by too low a suspended ceiling.
Long-lasting Air Filter Screen
Equipped with an upgraded long-lasting air filter screen, it is more efficient and durable than conventional filters. It can extend the cleaning cycle and reduce maintenance frequency, making your use easier and more convenient.
Four-way Air Supply
The four-way air supply cassette unit adopts an original "four-fold" process evaporator, which increases the heat exchange area by 12%, enabling the unit to cool and heat up faster.
Main Functions
Powerful cooling & heating, safe auxiliary electric heating, ultra-quiet management technology, ultra-comfortable air supply management, high-quality inner grooved copper tubes, premium motors, and ultra-long air supply distance.
Product Overview
Yujingfeng explosion-proof air conditioners can be divided into cooling-only and cooling & heating types based on performance. Structurally, they are classified into split wall-mounted explosion-proof air conditioners, split cabinet-type explosion-proof air conditioners, window-type explosion-proof air conditioners, ceiling cassette explosion-proof air conditioners, etc.
Built on the basis of high-quality branded air conditioners, explosion-proof air conditioners are designed for explosion protection in accordance with the requirements of the GB3836 series standards, and undergo explosion-proof processing with special manufacturing techniques and methods.
Features of Explosion-proof Air Conditioners
Adopts a flameproof structure with strong corrosion resistance, especially suitable for occasions with corrosive explosive gases.
Uses internationally renowned brand compressors, ensuring stable and reliable cooling (heating) performance, low noise, and a long service life.
Adopts composite explosion-proof types and comprehensive protection measures such as overheating and pressure protection.
All functional statuses are displayed on an illuminated LCD screen, which is clear and intuitive.
Allows adjustment of temperature level and air volume.
This product integrates cooling, heating and automatic defrosting functions. Key components such as compressors and fans are all specially treated for explosion protection, realizing full-unit explosion-proof performance. The explosion-proof product can be used in flammable and explosive mixed gas environments such as petroleum, chemical industry, pharmaceuticals, scientific research, military industry, and hazardous warehouses. Structurally, it adopts composite explosion-proof technologies including flameproof type, intrinsically safe type and encapsulated type. The control terminal is fully controlled by intrinsically safe circuits, which do not generate any electric sparks, ensuring convenient and safe use. Equipped with a high-efficiency multi-fin heat exchanger, it enables more sufficient contact between the refrigerant and air during circulation, greatly improving the cooling and heating effect of the air conditioner. Both manual and remote control modes are available.
Product Manufacturing Standards
The whole unit adopts international ultra-low voltage isolation intrinsically safe circuits, manufactured and processed with special explosion-proof craftsmanship. The design and production of the product strictly comply with the following relevant national standards:
GB3836.1-2010 Electroexplosive Devices for Explosive Atmospheres - Part 1: General Requirements
GB3836.2-2010 Electroexplosive Devices for Explosive Atmospheres - Part 2: Equipment Protected by Flameproof Enclosures "d"
