Product Positioning
Designed for 7-12HP R407C eco-friendly refrigerant large-scale commercial air conditioning, water chillers, and industrial refrigeration systems.
Core Technical Advantages
1. R407C Eco-Friendly Refrigerant: The DA series is optimized specifically for R407C eco-friendly refrigerant. As an eco-friendly alternative to R22, R407C features a lower GWP (Global Warming Potential), meeting increasingly stringent global environmental regulations.
2. Full Coverage of Large Displacement: Covering 7-12HP with a displacement of 117.3-184.2 cm³/rev. Cooling capacity ranges from 21.0 to 34.0 kW, meeting the full-scenario demands of large commercial and industrial refrigeration.
3. Mature D Series Platform: The DA series is developed based on the proven D series platform. It inherits all the technical advantages of the D series — core technologies such as asymmetric scrolls, rolling bearings, and dry bearings.
4. 3-Phase 50Hz Commercial Power: The Y1/Y1L suffix is optimized for 3-phase 380-415V/50Hz commercial power. 3-phase motors deliver smooth startup and high torque, making them suitable for high-load commercial scenarios.
5. Balancing Eco-Friendliness and Performance: While enabling R407C eco-friendly refrigerant application, it maintains the consistently high energy efficiency and reliability of the D series.
