MR/YF□Q-KEG1 Intelligent Wireless Automatic Gas Fire Extinguishing Device Debuts, Leading a New Era in Electrical Fire Protection

2025-11-19

The MR/YF□Q-KEG1 Intelligent Wireless Automatic Gas Fire Extinguishing Device is officially launched, designed specifically to prevent electrical fire hazards. It simultaneously monitors wire temperature, ambient temperature, and smoke via internal fire detection sensors, integrates various communication interfaces like RS485, 4G, and Lora, supports data upload to the cloud platform and remote control, enabling intelligent early warning and efficient suppression of electrical fires.

Core Advantages & Technical Highlights

The split-type product design allows users to easily replace the extinguishing unit after deployment, enabling multiple reuses and significantly reducing operational costs. Its employed perfluorohexanone extinguishing agent is non-toxic, harmless, and leaves no residue, requiring only a 4%-6% extinguishing concentration. It is suitable for occupied spaces and sensitive electrical equipment, and features a non-pressurized design, eliminating leakage risks.

Compared to traditional agents like Ultra-fine Dry Powder, Hot Aerosol, and HFC-227ea, Perfluorohexanone excels in safety, environmental friendliness, and applicability. It has a low harmful concentration (0.1%), leaves no residue, poses no asphyxiation risk or corrosive by-products, and is environmentally friendly, making it the ideal choice for electrical equipment protection.

Flexible Configuration & Wide Applicability

The device offers multiple models from MR/YF0.18Q/KEG1 to MR/YF1.5Q/KEG1, with agent quantities ranging from 180g to 1500g and protected spaces from ≤0.3m³ to ≤3m³, meeting the needs of various scenarios. It supports total flooding or local flooding application methods, features simple installation (nut press fit), operates in a wide environmental range (-40~+85°C, <95% RH), and includes multiple activation methods: logical, remote, manual forced start, and over-temperature activation.
