The "Fron Keeper" is a self-developed leak detection device that can detect refrigerant leaks at an early stage of approximately 10% by utilizing ultrasonic technology, installed in refrigeration units. It continuously collects, measures, and monitors various data such as outdoor temperature, liquid refrigerant temperature, discharge temperature, suction temperature, and electrical power (current) 24 hours a day, with a unique system that determines leaks. The collected data is automatically sent to a server every 10 minutes, allowing for centralized management of multiple refrigeration units via the web without the need to visit the site. In the event of a leak detection, an automatic email notification is sent to the responsible person. 【Features】 ■ Early detection of refrigerant leaks using ultrasonic technology ■ IoT-enabled refrigeration equipment through Fron Keeper ■ Reduction in electricity and repair costs ■ Prevention of inventory and sales opportunity losses ■ Extension of equipment lifespan *For more details, please refer to the PDF document or feel free to contact us.
