CRX
The CRX Refrigeration Control Panel from BTU Ventilation is engineered from the ground up to be the most dynamic and efficient refrigeration controller on the market. Simplicity of operation, combined with sophisticated control logic make this a key component for a storage system that utilizes refrigeration.
Standard Features
Surge Protection
Safeguards against power surges, ensuring the system operates smoothly without damage.
Single Phasing Protection
Prevents damage in case of power phase loss, keeping the system safe.
Patented Dyanmic Superheat Control
(US Patent 8,156,750)
Low Superheat Protection
Protects the compressor by ensuring no liquid refrigerant enters, preventing potential damage.
Overcurrent Protection
Monitors and prevents excessive current draw, protecting the system from overload.
Crankcase Heater Alarm
Alerts you if the crankcase heater malfunctions, preventing compressor damage.
Condensing Fan Alarm
Alerts in case of fan issues to ensure efficient operation.
Blackout/Brownout Protection
Keeps the system safe during power outages or fluctuations.
Our units are equipped with onboard VFD control, offering several key advantages:
Tighter Control
Compressors can adjust output from 50% to 120% without shutting off, ensuring optimal efficiency.
Compressor Protection
Built-in faults in the VFD stop the compressor in case of issues, enhancing system reliability.
Energy Savings
Independent studies show that VFD-controlled compressors can result in 30% power savings compared to traditional contactor systems.
Features & Benefits
Advanced Data Access
BTU is the only system in the industry to pull all refrigeration data from local or remote access on the BTU XT app. It also provides a data tunnel for technical assistance via the panel. Standard features include full operational records.
Custom Programming
designed to deliver unique functionality for every circumstance, ensuring seamless adaptability, optimal performance, and reliable crop preservation.
Auto Unloading
The system automatically unloads in response to high amps, high pressure, low suction, and high temperature conditions to correct potential issues. For instance, in high-ambient conditions, the system unloads just enough to control parameters until conditions stabilize.
Electronic Expansion Valve Control
BTU utilizes our patented EEV control technology in electronic expansion valve control, with a custom controller that ensures maximum evaporator efficiency, preventing liquid from reaching the compressor while maximizing cooling output.
Simplified Troubleshooting
All relays have LED indicators for easy troubleshooting, and all terminal blocks and wires are clearly numbered to match electrical prints.
Coordinated Compressor Staging
In two-compressor systems, staging is coordinated between compressors to ensure equal run time. The lead compressor ramps down to 50% when demand is low, and the lag compressor starts at 50%. This smooth transition reduces unnecessary cycling and ensures optimal efficiency.
Constant Communication Between Compressors
Both compressors continuously communicate, and if one experiences an issue, the other takes control, ensuring uninterrupted operation.
These innovative features provide unmatched reliability, efficiency, and protection, setting BTU CRX apart from others in the industry.
