Freon alarms essential for cold storage safety inspections, meeting cold storage safety regulations, worry-free acceptance
Product Introduction
I. Freon alarms essential for cold storage safety inspections, meeting cold storage safety regulations, worry-free acceptance Product Overview
Freon gas alarm (refrigerant gas detection alarm system), composed ofGas alarm controller + Freon gas detectorComposed of, belonging to industrial fixed gas detection equipment. Specifically designed for real-time concentration monitoring of refrigerant leaks such as R22, R32, R134a, R410A, widely used in refrigeration machine rooms, cold storage, central air conditioning machine rooms, refrigerant filling workshops, pharmaceutical cold chain warehouses and other scenarios. The equipment performs 24-hour online detection of Freon concentration in the air. When the leakage concentration reaches the preset alarm threshold, it immediately triggers sound and light alarms and can link with fans, solenoid valves and other equipment to promptly eliminate leakage hazards, protect on-site personnel safety, and meet safety supervision and cold storage safety acceptance specifications.
II. Freon alarms essential for cold storage safety inspections, meeting cold storage safety regulations, worry-free acceptance Product Introduction
Freon refrigerant is colorless and odorless, difficult to detect after leakage; refrigerants such as R32 are flammable, and large accumulation can easily cause explosion and suffocation, while also causing refrigerant loss and environmental pollution. This Freon alarm system uses dedicated infrared/semiconductor sensors, with detectors installed in areas prone to leakage accumulation, collecting Freon concentration signals in real time and transmitting them via wired connection to the alarm host. The host displays on-site concentration values in real time, with sound and light prompts when exceeding limits; supports RS485 and 4-20mA signal output, can connect to PLC, DCS, and cloud platforms for remote monitoring. The whole machine has an explosion-proof design, suitable for humid cold storage and interference-heavy industrial environments in machine rooms. The complete system has full qualifications, can be used for project safety acceptance, and supports on-site installation and commissioning and solution customization.
