Product Overview:

The Leo RPA system is a high-efficiency canned pump designed for the HVAC and heat pump market. It utilizes a permanent-magnet, variable-frequency canned motor and offers advantages such as high energy efficiency, quiet operation, a leak-free canned design, intelligent control, adjustable speed settings, compact size, condensation protection, and multiple safety features.

Product Features:

1. High Efficiency & Energy Saving: Uses a high-efficiency permanent-magnet motor for superior operational efficiency and energy savings; incorporates a new hydraulic design to significantly boost system performance.

2. Quiet Design: Features a canned, water-cooled structure that eliminates the need for a cooling fan; noise levels as low as 40dB ensure quiet, comfortable operation.

3. Intelligent Control: Smart control system with an LED display and one-touch operation, offering visible and flexible settings.

4. Leak-Free Canned Design: Canned structure eliminates the need for mechanical seals, removing the risk of fluid leakage.

5. Compact Size: Reduces volume and weight by up to 50%; includes dedicated PPR thermal adapters for easier installation and maintenance.

6. Multiple Protections: Includes protection against dry running, rotor blocking, over-voltage, under-voltage, overload/over-current, and phase loss.

7. Automatic Adaptation: Features three constant-pressure modes that automatically adjust flow and power to suit various operating environments.

8. Condensation Protection: Control board and motor utilize potting technology to prevent damage caused by condensation.

Product Applications:

The RPA series is primarily used in HVAC and heat pump systems. The circulation pump drives the circulating medium (such as water or antifreeze) through the heat pump system's piping, ensuring efficient heat transfer between the main unit and terminal equipment.
