FAQs
Q1: For our application (e.g., Cold Storage vs. Process Chilling), should we choose Screw, Reciprocating, or Centrifugal compressors?
A: The choice depends on capacity and application. We recommend: Screw for large, stable loads and high efficiency; Reciprocating for smaller capacity or specialized low-temperature use; and Centrifugal for very high-capacity HVAC/chiller applications. We offer a data-driven sizing analysis.
Q2: Are your system accessories (e.g., oil filters, valves, controls) proprietary, or can we easily source compatible, standardized replacement parts globally?
A: Our systems are designed with industry-standard interfaces and utilize high-quality, globally recognized components. We ensure that critical accessories and spare parts are readily available through our own supply chain and cross-reference to minimize emergency lead times.
Q3: How do you precisely calculate the required cooling load (BTU/hr or kW) and determine the correct compressor size for my specific process/cold room?
A: We perform a comprehensive heat load analysis that considers ambient temperature, product load, air infiltration, insulation U-values, and processing time. We use this data to select a compressor with the optimal capacity and EER/COP (Energy Efficiency Ratio/Coefficient of Performance) for your target temperature.
Q4: What is the warranty period for your main compressor unit and core accessories, and what is your guaranteed lead time for emergency spare parts?
A: We provide a comprehensive warranty package (typically $12$-$24$ months on the compressor). We maintain a global inventory of critical spares and commit to an emergency parts lead time (e.g., $24$-$72$ hours to major industrial hubs) to ensure minimal operational disruption.
Q5: What is the system's Total Cost of Ownership (TCO), and what technologies do you employ to maximize energy efficiency (SEER/IPLV)?
A: We provide a detailed TCO breakdown encompassing purchase, installation, maintenance, and projected energy costs. We prioritize Variable Speed Drive (VSD) compressors and advanced control systems to modulate capacity, minimizing energy consumption during part-load operation and maximizing long-term savings.
Q6: We conduct annual targeted procurement of compressors and repair kits to sustain production. I'd like to know if there are any contract discounts available?
A: Absolutely. Our primary strength lies in supply capability. Whether it's OEM manufacturing or global inventory searches—from components to complete units—we can match your needs with the nearest partner's inventory for rapid delivery. Our global alliance enables transactions at wholesale agency rates. Welcome aboard! Cheers!!
