Water-Cooled Inverter Unit — Highly Inverter 1.5-5.5HP
【Easy Maintenance with Direct Fault Code Readout】
Easy Maintenance: Error codes displayed on control panels enable quick fault diagnosis with predefined solutions.
【Large Drive Module for Stable High-Precision Control】
Robust Drive Module: Enhanced stability with reduced electromagnetic interference, extended component lifespan, supports high-load precision control.
【Water-Cooled Heat Rejection Far Superior to Air Cooling】
Water-Cooled Cooling: Superior heat dissipation per unit volume vs. air-cooled systems, reduces evaporator frosting.
【Inverter Energy Saving with On-Demand Speed Control】
Energy Efficiency: Inverter-driven compressors auto-adjust speed to actual load. Liquid injection cooling via electronic expansion valves reduces energy consumption.
