🌡️ High Performance at Speeds
Backed by real-world data, the performance curves show strong cooling capacity and consistent mass flow across a wide range of evaporation temperatures and speeds (3,000–5,000 RPM), even under demanding conditions (condensing temp: 54.4°C).
🔋 Flexible Power Options
Whether powered by battery, solar, vehicle, or grid (via AC-DC converter), the QX19 is built for versatility. Its low power input and silent operation make it a perfect match for portable freezers, medical cooling units, mobile fridges, and compact electronics thermal management.
📊 Smart and Reliable
From -25°C to +20°C evaporator temps, the QX19 ensures optimized input power and high nominal capacity, ensuring energy-saving cooling on the go.
Easy Integration with Your System for Advanced Control
Integrating RIGID’s drive board (PCB) and optional display panel into your system is simple - perfect for users who need advanced functions or want to control the compressor using their own software.
The motor drive board enables variable-speed operation, allowing you to adjust the cooling capacity by changing the compressor speed. It accepts a 0–5V DC analog control signal to regulate speed precisely.
- Minimum speed: 2,000 RPM (when control voltage is 0.7V or lower)
- Maximum speed: 6,000 RPM (at 4.5V or higher)
- Between 0.7V and 4.5V, the speed control is linear and can be calculated using the formula: S = 1132 × V + 1408
- Where S = compressor speed in RPM, and V = control voltage in VDC.
This flexible setup gives you smooth and reliable control, making it easy to customize cooling performance based on your specific application requirements.
