The EXTRCOOL Inverter Cold Room, Remote Monitoring That Keeps Every Degree in Your Phone

4G IoT as Standard, Alarms to Three Parties and Power-Cut Memory: How the Cold Room Goes Unattended in the Phone

The EXTRCOOL answer to the unwatched cold room is putting the room in the phone: every unit ships with a 4G IoT module as standard, the mobile app showing room temperature, temperature trend, compressor and fan status and electricity use with settable alarm thresholds, and a 5,000-square-meter supermarket running six units from 2 to 16 horsepower reports the phone view as the most reassuring feature. Alarms push to the user, the factory and the installer at the same time, a pharmaceutical warehouse manager no longer receiving midnight calls to drive to the warehouse, and the unit restores the pre-outage setpoint automatically after a power cut with OTA upgrades refining the algorithm without opening the machine. A garlic-sprout grower equipped 17 greenhouses and signed more than 400 units after a two-month trial, a white-strawberry facility runs eight 16-horsepower systems with over 95 percent premium-grade fruit and labor down 50 percent, and a fruit wholesale market installed more than 80 systems on one centralized platform cutting operations labor by nearly 40 percent. EXTRCOOL provides variable-frequency cold storage solutions.
