Industrial Cold Water Machine - -30°C to +5°C - China Manufacturers & Suppliers | High-Performance Freezer Factory
Design Advantages
Compact Structure & Smooth Operation
Condenser and evaporator units utilize efficient heat transfer tubes. The host selection features imported, high-efficiency hermetic scroll compressors, offering a compact, lightweight design with flexible installation. With fewer moving parts, it delivers high energy efficiency, low noise, low vibration, and stable performance, operating 20%-30% more efficiently than reciprocating compressors.
Improved Energy Control System
The conditioning units start and stop according to load changes to maximize energy efficiency. The computer control system adjusts the unit's energy output based on thermal load changes. By monitoring the difference between actual load and user settings, the microcomputer quickly determines the required energy, optimizing multi-system operations to minimize consumption even at partial loads.
Simple & Intuitive Interface
Equipped with a microcomputer program controller (Chinese/digital display), allowing users to start the unit with a simple touch. The panel displays operating status and text parameters at a glance. No professional operator is required. It precisely controls temperature within 1℃ (special accuracy up to 0.1℃) with a setting range of 5℃-50℃.
Microcomputer Protection
Features comprehensive safety functions, including compressor coil overcurrent protection, pump overcurrent protection, cold water flow switch, low cooling protection, high water temperature protection, compressor overload protection, frequent start/stop prevention, abnormal voltage protection, and high/low pressure protection.
Multiple Protection, Safe & Reliable
Beyond the internal compressor protection module providing under/over voltage, phase failure, and overload protection, the refrigeration system is equipped with advanced pressure control units and other safety devices to make operation completely foolproof.
Optimized Mobility & Efficiency
Engineered for maximum refrigeration efficiency while keeping noise to a minimum to meet environmental standards. Air-cooled chiller pumps are highly mobile and easy to relocate without assembling cooling towers.
Easy Installation & Setup
All components are fully installed and run-tested at the factory. Refrigerants and refrigeration oils are pre-filled, so users simply need to connect the waterway and electrical circuit to put the unit into use, saving time and setup costs.

Frequently Asked Questions (FAQ)
What are the core design advantages of the hermetic scroll compressor?
The hermetic scroll compressor has fewer moving parts, utilizes flexible compression, and offers high energy efficiency with low noise and operating costs. Because the compression process is continuous without pulses, the unit provides stable performance, minimal vibration, and smooth running characteristics, achieving 20%-30% higher efficiency than reciprocating compressors.
How does the energy control system optimize power consumption?
The unit starts and stops automatically based on load changes. The integrated microcomputer monitors the difference between the actual thermal load and the user settings to quickly adjust the energy output. In multi-system configurations, it optimizes output to ensure the lowest energy consumption even under partial load.
What safety protections are integrated into the microcomputer controller?
The controller provides multiple built-in protections, including compressor coil overcurrent protection, pump overcurrent protection, cold water flow switch, low cooling protection, high water temperature protection, compressor overload protection, frequent start/stop prevention, abnormal voltage protection, and high/low pressure protection.
Is the chiller unit easy to install?
Yes. All components are pre-assembled and run-tested at the factory, and the systems are pre-charged with refrigerants and refrigeration oils. Users only need to connect the external waterway and electrical circuit to put the unit into operation, reducing installation and commissioning time.
What is the standard operating temperature range?
The standard chilled water temperature range is 5℃ to 35℃, and the outlet water temperature range is 3℃ to 18℃. The ambient temperature for the condenser should not exceed 35℃ under standard operating conditions.
Can these chiller units be customized?
Yes. These models can be customized according to specific customer requirements, including configurations for non-standard ambient temperatures (such as a maximum ambient temperature of 5℃).
