Traditional chillers often struggle to maintain stable cooling in extreme low-temperature scenarios, leading to product spoilage or process failures. Our Semi-hermetic Screw Compressor Water Cooled Chiller (-5~-40℃) solves this pain point for three core industries:
Food Freezing & Preservation: Ideal for large-scale seafood processing plants and frozen food warehouses, it maintains a consistent -18~-40℃ environment to lock in freshness and extend shelf life by 30% compared to conventional cooling systems.
Pharmaceutical Cold Chain: Complies with GMP standards for storing temperature-sensitive drugs (e.g., vaccines, biological reagents), ensuring no fluctuations beyond ±0.5℃ to guarantee drug efficacy.
Industrial Low-Temp Processes: Supports chemical crystallization, plastic molding cooling, and metal heat treatment in low-temperature workshops, where precise -5~-25℃ cooling is critical for product quality.
Compact Layout: Developed with CNC precision machining, the unit features a space-saving design (minimum dimension: 827×330×660mm for model 4YD-3.2) that reduces installation space by 20% compared to similar deep-low-temperature chillers.
Stable Operation: Equipped with a hardened crankshaft and low-friction bearing set, the compressor runs with vibration ≤55dB—quieter than industry averages—making it suitable for noise-sensitive environments like pharmaceutical labs.
Compressor Body: Made of high-grade cast iron, it resists corrosion and thermal expansion even at -40℃, ensuring a service life of over 10 years.
Key Components: Chrome-plated piston rings enhance wear resistance; valve reeds use imported impact-resistant spring steel to improve refrigeration efficiency by 12%.
Pre-Installation Support: Our engineers conduct on-site surveys to confirm water supply pressure (required for water-cooled models) and installation space, providing customized layout plans.
Commissioning & Training: Free on-site commissioning includes refrigerant filling adjustment and operating parameter setting; we also train staff on daily monitoring (e.g., temperature, pressure).
Maintenance & Spare Parts: Annual maintenance reminders via email/SMS; global spare parts warehouses ensure delivery of critical components (e.g., PTC sensors, valve plates) within 5 business days.
Documentation: Access to the 2024 updated Semi-hermetic Screw Compressor Operation Manual via our official website, including troubleshooting flowcharts for common issues.
