220V Digital Thermostat Microcomputer Temperature Controller for Commercial Refrigeration Freezer & Display Case

Maintain optimal cold storage, protect perishable inventory, and streamline commercial cooling operations with this 220V Digital Microcomputer Temperature Controller. Engineered for commercial freezers, glass-door display cabinets, cold storage rooms, and beverage coolers, this heavy-duty thermoregulator provides precision temperature regulation alongside automated defrost management. Equipped with a high-accuracy NTC sensor probe on an extended cable, it continuously monitors internal temperatures and regulates refrigeration compressor cycles and defrost heater elements via independent relay outputs. Featuring a clear digital LCD/LED display, adjustable hysteresis differential, compressor delay protection, and customizable high/low temperature alarms, this controller ensures consistent cold chain performance and energy efficiency.

Key Features

• Dual Cooling & Defrost Regulation: Manages both refrigeration compressor cycles and automated defrost cycles for complete cold storage climate automation.

• Microcomputer High-Precision Control: Advanced micro-processor delivers tight temperature accuracy across wide commercial freezing ranges.

• Integrated NTC Waterproof Sensor Probe: Comes with a durable, high-sensitivity NTC thermal probe on a flexible wire extension for accurate internal monitoring.

• Built-in Equipment Protection: Features customizable compressor start-delay timers, sensor failure alerts, and high/low temperature alarms to prevent stock spoilage.

• High-Contrast Digital Display: Clear numerical display screen provides live temperature visibility in commercial kitchens, supermarkets, and walk-in freezers.

Why Choose Our Refrigeration Temperature Controller

Uncalibrated mechanical thermostats drift over time, causing evaporator coils to freeze up into ice blocks or temperatures to drop, risking food spoilage and health code violations. Standard single-function temperature switches lack automated defrost control and compressor delay protection, leading to shortened equipment lifespans and costly emergency repairs. This microcomputer temperature controller combines refrigeration and defrost switching, NTC probe accuracy, compressor delay safety timers, and clear digital visibility—giving your commercial freezers, cold rooms, and display cases an instant professional upgrade.
