Refrigeration controls, costs, alerts

Large refrigeration systems are important assets. However, they are costly to run and even more expensive when they malfunction. PowerWise offers a refrigeration control unit that will reduce refrigeration energy costs, help avoid equipment failures, and send alerts about temperature changes, including food safety issues.

Reduce Refrigeration Energy Costs

Know the cost and runtimes of individual refrigeration and freezer units. Identify equipment using too much energy or needing service. Use these numbers to see if upgrading to energy-efficient equipment makes more sense. Plus, adding a defrost controller can significantly reduce energy wasted on the defrost cycle. PowerWise online reports show the savings from changes you make to refrigeration systems.

Ensure Reliable Operations, Safe Temperatures

Avoid expensive equipment downtimes and food spoilage with monitoring from PowerWise. The powerful analytics can report on compressors short cycling, overloaded refrigeration units, and maintenance reminders. Receive alerts and reports if temperatures are not suitable. Plus, the software tracks cumulative alerts to help identify problematic equipment or behavior.

Refrigeration Controls Explained

Defrost for refrigeration units typically run on a set schedule. Even if there is no frost to be removed, defrost will run. PowerWise systems prevent unnecessary defrost cycles. A typical defrost cycle heats the coil to 120 degrees Fahrenheit, which is excessive. The refrigeration control will only heat the coil to the necessary temperature for defrosting which improves efficiency and speeds up post-defrost cooling.

A refrigeration controller provides many advantages:

• Trigger defrost based on coil temperature
• Cycle coil heat off and on - reduces energy costs while advancing defrost cycle
• Turn off defrost when coil temperature reaches 50 degrees F rather than 120 degrees F and will achieve the same defrost goal

The dashboard reports on several conditions, including:

• Temperatures - setpoint, room, evaporator coil (2)
• Status - door, compressor, fan, defrost, standby
• Alerts - high and low temperature, door left open, sensor offline, defrost terminated on time, excessive defrost & power failure
• Energy - verify savings and performance with real time & historical reports
