Product Introduction
Freon cold storage fan alarm Fixed safety monitoring for cold storage fans - Product Overview
The Freon cold storage fan alarm is an online gas detection device used for fixed safety monitoring of cold storage fans. Search keywords: Freon cold storage fan alarm, fixed safety monitoring for cold storage fans, Freon alarm. The alarm is fixedly installed in the fan unit area and can continuously detect Freon concentration. When the concentration exceeds the set threshold, it emits sound and light alarms, and optional relay outputs can be used to link exhaust ventilation or shut down refrigeration equipment. In fixed safety monitoring for cold storage fans, the Freon cold storage fan alarm can reflect on-site gas risks in real time and help staff respond promptly.
Freon cold storage fan alarm Fixed safety monitoring for cold storage fans - Working Principle
Freon cold storage fan alarms usually use semiconductor sensors or infrared sensors to output electrical signals by detecting Freon concentration and calculate gas concentration. In fixed safety monitoring for cold storage fans, Freon cold storage fan alarms convert detection signals into 4-20mA, RS485, or Modbus outputs and can be connected to PLC, DCS, and gas alarm control systems. The alarm is fixedly installed near the fan unit or on the wall, with moisture-proof and explosion-proof functions, and the protection rating can reach IP65 or IP66.
Freon cold storage fan alarm Fixed safety monitoring for cold storage fans - Application Scenarios
Freon cold storage fan alarms are widely used in cold storage fan units, evaporators, air outlets, and pipeline valve areas. In fixed safety monitoring for cold storage fans, Freon cold storage fan alarms can be fixedly installed near the fan units, pipeline valves, and personnel inspection passages. The alarms can be linked with exhaust fans, shut-off valves, and fire protection systems to achieve automatic handling. For large cold storage facilities, Freon cold storage fan alarms can also form a multi-point monitoring network and upload data uniformly to the control room.
Freon cold storage fan alarm Fixed safety monitoring for cold storage fans - Technical Advantages
Freon cold storage fan alarms have advantages such as fast response, good stability, and strong anti-interference ability. In fixed safety monitoring for cold storage fans, Freon cold storage fan alarms use industrial-grade sensors and explosion-proof housings, making them suitable for long-term operation. The alarm supports sound and light alarms, remote output, and fault self-diagnosis, and is easy to maintain. When selecting a Freon cold storage fan alarm, attention should be paid to detection range, accuracy, response time, explosion-proof rating, and output signal to ensure it meets the needs of fixed safety monitoring for cold storage fans.
