FAQ

How does the step capacity control improve the overall lifespan of the semi-hermetic screw compressor?

By utilizing a 0/25/50/75/100% or 0/33/66/100% capacity control system, the compressor avoids brutal, full-load hard starts. It smoothly ramps up or down based on the exact thermal demand. This drastically reduces mechanical wear on the internal screw rotors and minimizes electrical stress on the motor windings, significantly extending the operational lifespan of the compressor and reducing maintenance intervals.

Can this air-cooled system effectively operate in environments with heavy airborne particulate matter?

Yes. The finned-tube condensers are meticulously designed with optimized fin spacing to allow for high-volume airflow while minimizing the accumulation of dust and debris. Furthermore, the high-strength welded frame and outdoor-rated paint protect the internal components. For extremely dusty environments, we can consult on specific placement strategies and additional pre-filtration options.

What makes the SUS304 stainless steel water tank and piping critical for process cooling?

Industrial process cooling often involves fluids that can be mildly corrosive or highly sensitive to contamination. SUS304 stainless steel provides exceptional resistance to oxidation and chemical scaling. This ensures that the water or coolant circulating through your expensive production machinery remains completely free of rust and particulate degradation, protecting your entire hydraulic loop from blockages.

How does the Siemens PLC integrate with our existing factory monitoring systems?

The integrated Siemens PLC acts as the intelligent hub of the chiller. By utilizing the optional RS485 communication interface, the unit can transmit real-time data—such as inlet/outlet temperatures, operating pressures, and fault codes—directly to your central Building Management System (BMS) using standard industrial protocols, enabling seamless remote monitoring and centralized control.

Is it possible to customize the evaporator type if our process fluid is highly acidic?

Absolutely. While the standard configuration utilizes a highly efficient dry shell-and-tube evaporator, we offer specialized acid and alkali-resistant evaporator options. These are constructed using advanced anti-corrosive alloys and specific coatings engineered to handle aggressive chemical fluids without degrading the heat transfer efficiency or risking structural failure.
