Low-Temperature Water Cooled Screw Chiller

Built for sub-zero cooling conditions. Engineered by a professional chiller manufacturer, our low-temperature industrial chillers are engineered to deliver reliable cooling fluid down to -85°C. Utilizing specialized anti-freeze technology, this heavy-duty refrigeration unit perfectly bridges the sub-zero gap that standard water chillers cannot reach.

Introduction

Low-Temperature Water Cooled Chiller – Box Type

This model is perfect for vaccine and plasma freezing in the medical industry, rapid crystallization of chemical reactants, and 24/7 cold-endurance simulation testing of high-precision aerospace instruments. As a heavy-duty water cooled chiller, the water temperature remains strictly locked in an extreme sub-zero state without fluctuations. It is also ideal for quiet, dust-free processes that demand easy operation and precise control, ensuring your line never fails.

 

Key Features
1. Ultra-Quiet Operation: The water cooled chiller unit has no large external exhaust fans. Heavy heat dissipation is handled by an outdoor cooling tower, making it almost unnoticeable inside the workshop and building a quiet working environment.
2. Ultra-Efficient Deep-Cooling Exchange: Premium shell-and-tube (or plate) heat exchangers optimized for deep-cooling refrigerants ensure thorough heat exchange, delivering significantly higher energy efficiency than air-cooled units of the same power.
3. Fully Enclosed Dustproof Design: The fully sealed cabinet effectively blocks out workshop dust, keeping internal components clean and greatly reducing daily maintenance frequency.

 

Low-Temperature Water Cooled Screw Chiller

This giant industrial screw chiller is built for large centralized chemical deep-freezing systems, large-capacity deep-cooling testing in national laboratories, and specialized rubber/plastic modification freezing processes. On harsh, 24/7 ultra-low temperature production lines, it acts like a shield to lock the temperature down and efficiently handle explosive heat spikes, ensuring top-tier product quality.

 

Key Features
1. High-Efficiency Deep-Cooling: Purpose-built for extreme ultra-low temperature, large-capacity industrial jobs. The shell-and-tube exchanger pairs with a powerful screw compressor to show an extremely high energy efficiency ratio during continuous heavy runs.
2. Multi-Stage Smart Control & Full Protection: Equipped with a high-end PLC and touchscreen. It features dozens of safety protections (phase loss, overload, anti-freeze, oil temperature/pressure protection) with a highly intuitive interface.
3. Virtually Wear-Free & Long Reliability: The screw compressor has a simple structure, runs smoothly, and experiences minimal wear. It supports hundreds of thousands of hours of trouble-free operation to keep your production lines running indefinitely.
