Sub-Zero Cooling Range: Designed for reliable operation down to -40°F / -40°C (typical, specify your range) using glycol/water mix.
Freeze Protection: Glycol solution prevents freezing in pipes, coils, and process equipment, ensuring safe operation in extreme cold.
Precision Temperature Control: Maintains tight stability (±0.5°C) essential for sensitive processes.
Corrosion-Resistant Construction: Critical components (evaporator, reservoir, piping) use stainless steel or protected materials to withstand glycol solutions.
Industrial Durability: Built for 24/7 operation in harsh environments with high-quality compressors (screw or scroll) and heavy-duty components.
Secondary Cooling Loop: Safely isolates the chiller’s refrigerant circuit from the process, protecting sensitive equipment.
High Glycol Concentration Capability: Engineered to handle the viscosity and thermal properties of high-% glycol solutions.
Advanced Controls & Alarms: Programmable controllers, data logging, and comprehensive safety alarms for critical process monitoring.
Flexible Configuration: Available as air-cooled or water-cooled models to suit facility infrastructure.
