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.
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.
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.
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.
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.
A: Absolutely. Our primary strength lies in supply capability.
