Bitzer

Bitzer Compressor

Bitzer pioneers high-reliability compressors for industrial refrigeration and HVAC. The Semi-Hermetic Piston Series (0.5-100HP) achieves a 20% higher COP through patented valve plates, supporting evaporation temperatures of -40°C with R22 and down to -70°C with R507. The Oil-Injected Screw Compressors (50-140HP) enable 15-100% stepless capacity control via IDV technology, reducing part-load energy consumption by 30% for applications such as chillers and rooftop units. Furthermore, the Ammonia Screw Series (e.g., OS.A95) uses a natural, zero-GWP refrigerant and features automatic Vi regulation, making it an ideal solution for freezing plants and marine systems.

Core Retrofit KPIs

Technical Basis: CO₂/NH₃ cascade system has a COP of 4.2 compared to a single-stage system of 2.8. The system features PID-controlled glycol valves and redundant compressors, with temperature control within ±0.3°C during critical metabolic periods (to avoid heat stress). The R290 turbine plate commutation speed is 3.5 m/s (compared to a conventional 1.2 m/s).

Refrigeration Technologies

CO₂/NH₃ Cascade System (-45°C): Low-temperature stage: CO₂ (evaporation at -45°C) rapidly cools fermenters, addressing yeast heat stress. High-temperature stage: NH₃ (-10°C) cools malt, a GWP=0 environmentally friendly working fluid. Energy efficiency mechanism: Staged compression reduces overheating losses, achieving a COP increase of 40%.
Solar-Assisted Absorption Chiller: Heat recovery: Solar panels (120 square meters) drive lithium bromide chillers.
Free cooling capacity: ≥15% cooling capacity is provided in summer, and the utilization rate of Nanka's sunlight resources reaches 83%.
