About this product
Product information from the supplier.
As a heating-and-cooling integrated unit exclusively designed for jacketed reactors, it combines an ultra-wide temperature range with explosion-proof safety. With a temperature span from as low as −105°C to as high as 300°C, it meets diverse experimental requirements; its temperature-control accuracy of ±0.5°C makes it a reliable partner for stable thermal management during reaction processes.
Electrical explosion protection: Equipped with an ExdⅡ BT6-rated explosion-proof control box,
Explosion-proof circulating pump: Equipped with an ExdⅡ BT4-class explosion-proof circulating pump, suitable for flammable and explosive process conditions in industries such as chemical and pharmaceutical.
Intelligent Safety Protection: Equipped with built-in automatic fault diagnosis and real-time status monitoring, the system immediately shuts down and triggers an alarm upon detecting any abnormalities, providing dual-layer protection for both equipment and personnel.
Temperature range: 105°C to 300°C, meeting diverse experimental requirements such as low-temperature condensation and high-temperature reactions; temperature control accuracy of ±0.5°C combined with intelligent PID control ensures stable, fluctuation-free reaction temperatures.
Clean, sealed recirculation system: the entire liquid circulation loop is fully sealed—no external moisture ingress at low temperatures and no oil mist emissions at high temperatures.
