Enhance Safety and Save Energy with Advanced Door Monitoring 

The Modularm® DAC-55™ is a robust refrigerator and freezer door alarm and monitoring system engineered for OEMs who need reliability, efficiency, and safety in commercial kitchen environments.

Designed for walk-in coolers and freezers, the DAC-55 not only provides visual and audible alarms to ensure doors are not left ajar but also integrates seamlessly with refrigeration systems.

This unit actively reduces coil icing, improves energy efficiency, lowers maintenance costs, and protects stored products by maintaining proper temperatures. For enhanced safety, the DAC-55 supports an optional IP-1 Illuminated Pushbutton that doubles as a panic/entrapment alarm for personnel working inside compartments.

With user-selectable configurations, field-adjustable alarm delays, and automatic control of lights, fans, and solenoids, the DAC-55 replaces conventional switches and transforms walk-in cooler/freezer safety and energy management.

ETL-listed and tested in leading retail chains, it is a proven solution for OEMs requiring durability, compliance, and long-term value.

Benefits of the DAC-55™ Door Alarm Monitor

Lower Energy Costs: Reduces compressor run-time and unnecessary light usage.

Improved Product Integrity: Maintains consistent temperatures, minimizing spoilage and ensuring consistency.

Reduced Maintenance: Decreases coil icing and system wear for longer equipment life.

Faster ROI: Case studies show dramatic reductions in door-open hours, leading to measurable cost savings.

 Challenges the DAC-55™ Helps Solve

Energy Waste

Doors left ajar lead to skyrocketing energy costs. The DAC-55 reduces open-door time by up to 85% in pilot tests, directly lowering utility bills.

Coil Icing

Uncontrolled airflow causes icing and downtime. The DAC-55 reduces icing by managing fans and solenoids during door-open conditions.

 

Equipment Wear

Excessive compressor cycling shortens equipment life. Adjustable refrigeration shutoff delays reduce unnecessary cycling and increase lifespan.
