The price of a Bitzer compressor is primarily driven by its cooling capacity, displacement, and motor power. Buyers should distinguish between Semi-hermetic Reciprocating, Screw, and Scroll compressors. Key technical factors include the refrigerant compatibility (e.g., R404A, R134a, or CO2), operating temperature range (low, medium, or high back pressure), and the inclusion of IQ Modules for advanced monitoring. Ensure the unit features internal discharge relief valves and high-efficiency suction/discharge valves to justify the investment through long-term energy savings.
