Low Temperature Water Chiller Closed Loop Glycol Circulation For Chemical Reaction Cooling

Product Introduction

Achieve precise exothermic control and ensure process safety with our Low Temperature Water Chiller. Specifically engineered for Chemical Reaction Cooling, this unit utilizes a closed-loop propylene glycol (PG) or ethylene glycol (EG) circulation system to deliver stable, sub-zero cooling as low as -40°C. Unlike standard water chillers, our system prevents freezing in jackets and coils, while maintaining a sealed, contaminant-free environment. It is the definitive solution petrochemicals, specialty chemicals, and laboratory synthesis where thermal runaway prevention and batch consistency are paramount.
