To assist you in making an informed technical decision, we have compiled answers to the most critical inquiries regarding our parallel chiller units.
Q1: How does the 3-stage capacity control optimize electrical consumption?
The capacity control system dynamically adjusts the compressor's output to 33%, 66%, or 100% depending on the real-time heat load of your facility. By avoiding continuous full-power operation when demand is low, it drastically reduces unnecessary power draw, optimizing your overall energy expenditure.
Q2: Can this parallel unit be integrated into an existing central control system?
Yes, the intelligent microcomputer and PLC control systems are designed with standard communication protocols. This allows for seamless integration into your facility's existing Building Management System (BMS), enabling centralized monitoring and remote parameter adjustments.
Q3: What maintenance routines are required to ensure the 50,000-hour design lifespan?
To achieve maximum longevity, we recommend quarterly inspections of the pressure lubrication system, verifying the 7L-12L oil injection levels, and cleaning the shell and tube heat exchangers. The system's accessible layout makes these routine checks highly efficient for your maintenance crew.
Q4: How does the system handle potential electrical anomalies?
The unit features a comprehensive electrical protection suite, including phase reversal, phase loss, and motor overload protections. If an unstable power supply is detected, the system safely initiates a controlled shutdown to prevent any damage to the semi-hermetic screw compressor.
Q5: Is it possible to customize the unit for extremely corrosive environments, such as chemical refineries?
Absolutely. We offer specialized anti-corrosion treatments for the casing, customized alloy selections for the heat exchanger tubes, and hermetically sealed electrical enclosures to ensure the unit operates reliably even in highly aggressive chemical atmospheres.
