R290 Mini Compressor Manufacturer
RIGID mini bldc compressors are equipped with their own patent driver board to ensure high efficiency, variable speed control, and load-following capabilities, which allows you to set the speed and load following to precisely control the temperature.
The compact size, lightweight, and durability of RIGID mini compressors make them ideal for mobile and portable applications.
RIGID 24V R290 mini compressor consume less energy and are quiet. As an electrical power source, they can use battery, vehicle, grid, or solar power. They can also be powered by AC using an AC-DC converter.
A significant advantage to using R290 is its energy-saving potential. The result is a reduction in operating costs and a reduction in emissions of CO2 into the atmosphere.
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.
