H300-30 High Temperature Heating & Cooling Circulator, 50°C to 300°C
The Ai H300-30 High Temperature Heating & Cooling Circulator is a powerful and precision-controlled temperature control system designed for jacketed reactors, process vessels and other demanding laboratory and industrial applications.
With a working temperature range of 50°C to 300°C, the H300-30 combines 25 kW heating capacity, powerful circulation and active cooling in a fully closed-loop system. It is particularly suitable for applications requiring rapid heating, controlled cooling and stable temperature maintenance.
The advanced PID control system allows users to control either the circulating fluid outlet temperature or the actual reactor material temperature, providing excellent flexibility for different reaction processes.
