TEKIN’s customized twin-screw compressors utilize imported semi-hermetic twin-screw compressors from Bitzer (Germany) as their core power components. They are designed to deliver highly reliable and energy-efficient customized refrigeration solutions for industrial refrigeration, large-scale cold chain operations, and process cooling applications.
The units feature a redundant parallel design utilizing dual compressors; this configuration enables staged capacity modulation to match dynamic loads while providing mutual backup to ensure continuous system operation. Leveraging Bitzer’s high-efficiency asymmetric rotor profiles and micron-level manufacturing precision, the units achieve an operating efficiency more than 30% higher than traditional single-stage units when operating in low-temperature conditions of -40°C.
TEKIN offers comprehensive customization services—spanning system design, precision manufacturing, and intelligent control—dedicated to providing every client with a compressor unit perfectly tailored to their specific operating conditions.
A large-scale food cold chain logistics center in East China operates a low-temperature cold storage facility with a capacity of 50,000 tons, requiring stable temperature control between -22°C and -25°C. The original piston compressor units suffered from high energy consumption and rising failure rates; furthermore, the single-compressor design posed an operational risk where a single shutdown could halt the entire facility’s operations. The client urgently required a highly efficient, energy-saving, and reliable upgrade solution.
Based on the client’s dynamic annual thermal load profile, the TEKIN team customized a dual-compressor parallel screw unit:
Core Configuration: Equipped with two German Bitzer semi-hermetic twin-screw compressors (matched power ratings) sharing piping systems such as oil separators and liquid receivers.
Intelligent Control: Utilizes a Siemens PLC control system to automatically schedule single- or dual-compressor operation based on real-time load and temperature, achieving smooth cooling output matching at 0%, 50%, and 100% levels.
Operational Reliability: The two compressors serve as backups for each other; if one unit undergoes maintenance or fails, the other maintains low-temperature operations, completely eliminating the risk of a “single point of failure.”
Energy Efficiency: Intelligent single-unit operation during partial-load conditions improved the Integrated Part Load Value (IPLV) by approximately 25% compared to the original unit, resulting in annual electricity cost savings exceeding 400,000 RMB.
Stability and Reliability: After 12 months of operation, temperature fluctuations remained within ±0.5°C with zero unplanned shutdowns, ensuring the safety of stored goods.
Low Noise and Eco-friendliness: The dynamic balance characteristics of the twin-screw compressors, combined with the noise-reducing design of the semi-hermetic housing, kept equipment room noise below 75 dB, thereby improving the working environment.
