8. Low-Temperature Environment: Utilizes low ambient temperature operation control technology, capable of stable operation at low cooling water temperatures, with the cooling water temperature as low as 12°C.
Performance Features:
1. Oil-Free High Efficiency: The magnetic suspension bearing technology eliminates friction, enabling the unit to operate oil-free, enhancing energy efficiency, reducing energy consumption and operational costs. The horizontal opposed two-stage compression structure and the full film evaporation technology further boost the heat exchange and operational efficiency, ensuring the unit operates efficiently under various operating conditions.
2. Reliable and Stable: The dual protection mechanism with an automatic self-generating control mode and backup bearings ensures safe operation of the unit during power outages or other abnormal conditions. The design allows for unlimited emergency descent, enabling the unit to maintain rotor levitation even in the event of power failure. Additionally, the presence of the backup bearing ensures the compressor's lifespan in terms of service life.
3. Wide Operating Range: The unit employs variable speed operation combined with imported guide vanes (IGV) for cooling capacity regulation, ensuring stable operation under various operating conditions. This approach avoids additional flow losses caused by partially closing the IGV, thereby further enhancing the unit's operational efficiency.
4. Low Noise & Eco-Friendly: The oil-free and frictionless design of the unit reduces transmission noise, while the horizontal opposed impeller of the compressor and the external pipe-type return flow structure minimize aerodynamic noise. The specially designed compressor housing structure ensures excellent sound insulation and noise reduction, resulting in operating noise as low as 70dB(A). Additionally, using the eco-friendly refrigerant R134a, which has no ozone-depleting effects on the atmosphere, makes this unit excel in environmental protection.
5. Cost Savings: The high-efficiency operation and oil-free, frictionless design reduce the energy consumption and maintenance costs of the unit, allowing users to save costs more effectively during use, while also aligning with environmental protection goals of energy and emission reduction.
