Quick Response Controller (QRC)

The Heatcraft Quick Response Controller is a factory installed and tested control solution that provides superior system performance and energy savings by performing three key functions: Automatic Superheat Control, Room Temperature Control, and Optimized Defrosts for refrigeration unit coolers.

Factory Installed & Tested

Ease of Installation

• Pre-assembled controls package
• No installing or connecting components
• Reduced time and effort required for installation
• System will work optimally out of the box

Stand Alone

• Complexity and volume of electrical wiring decreased
• Faster installations and easier troubleshooting

Rapid Response - Electronic Expansion Valve (EEV)

Improved Temperature Control

• Designed to maintain product or process temperatures within a specific range
• EEV’s will allow system to reach optimal conditions faster
• Greater control over system temperatures

Precise

• Ideal settings already exist in the algorithm with an EEV
• Select the desired superheat and refrigerant type, the controller will automatically make necessary adjustments

Rapid

• Achieving and maintaining ideal superheat ensures equipment responds rapidly following compressor startup
• Refrigeration systems balance out quickly, adapt to changing conditions faster

Intelligent Demand Defrost

Demand Defrost

• Continuously evaluating system parameters, pressures, temperatures and valve position
• Executes a defrost cycle only when actual conditions warrant
• Results in overall energy savings, more consistent box temperatures and improved product integrity
