Product Description

Key Issues Addressed:

Inadequate Cooling Capacity

The G303DH-47D1 (2) has a cooling capacity of 8.65 KW, suitable for small to medium cooling needs.
The G303DH-50D1 (2) and G353DH-56D1 (2) have a cooling capacity of 10.71 KW, meeting moderate cooling loads.
Solves issues of poor cooling performance and slow temperature reduction in existing equipment.

Excessive Energy Consumption

Energy efficiency ratio of 2.75–3.25, significantly more energy-efficient compared to traditional compressors.
Utilizes high-efficiency rare-earth permanent magnet DC motors, reducing torque by 40%.
Addresses high electricity costs and operational expenses.

Noise and Vibration Issues

Scroll-type structure ensures stable operation with minimal vibration.
Noise levels as low as 60 dB(A), offering excellent quiet performance.
Resolves problems of noise disturbance and impact on the working environment.

Equipment Reliability Issues

Built on Hitachi’s 40 years of technical expertise, featuring patented technologies like laser welding.
Fewer components, simpler structure, and lower failure rates.
Reduces frequent repairs and production downtime caused by equipment failure.

Environmental Compliance Requirements

Compatible with eco-friendly refrigerants like R407C, meeting environmental standards.
Solves issues related to the phase-out of traditional refrigerants and non-compliance with environmental regulations.

Space Limitations

Compact structure, small size, and lightweight design.
Addresses challenges of limited installation space and difficulties in equipment upgrades.

Limited Operating Range

Wide operational range maintains high efficiency even under varying pressure ratios.
Solves issues of poor equipment adaptability to varying operating conditions.

High Maintenance Costs

Differential pressure oil supply ensures reliable lubrication.
Reduces frequent maintenance and high spare parts costs.

Advantages:

Technical Edge: Hitachi invented and pioneered the first scroll compressor for air conditioning, backed by 40 years of technological expertise.
High Efficiency and Energy Savings: Uses high-efficiency rare-earth permanent magnet DC motors, reducing torque by 40% and improving energy efficiency by one grade.
Reliability: Features three patented technologies—laser welding, enhanced oil supply, and oil control—ensuring more reliable operation.
Quiet Performance: Low vibration and low noise, renowned as an "ultra-quiet compressor."
Compact Design: Small size, lightweight, low energy consumption, and long lifespan.
Wide Applicability: Suitable for a broad range of refrigeration systems, including air conditioners, heat pumps, chiller units, and refrigeration units.

Application Scenarios:

Household air conditioners, commercial air conditioners, air-source heat pumps, industrial refrigeration equipment, cold storage units, and other refrigeration systems.
