High and Low Temperature Integrated Circulator: The Perfect Combination of Efficient Heating and Cooling

The high and low temperature integrated circulator is designed with advanced heating and cooling integration, featuring a large heat exchange surface that significantly accelerates both heating and cooling rates while reducing the consumption of thermal oil, greatly improving operational efficiency. The system supports continuous temperature rise and fall, utilizing high-temperature, high-pressure compressor technology that can initiate cooling directly from 350°C, ensuring rapid cooling and saving both time and effort

Safety

This series of equipment is equipped with multiple safety features, including self-diagnostic systems, overload protection for the refrigeration unit, high-pressure switches, overload relays, and high-pressure protection for the circulation system during high-temperature heating. These comprehensive safety measures ensure reliable and safe operation. The adaptive temperature control system continuously adjusts PID parameters based on specific process requirements (e.g., chemical reactions) to achieve optimal temperature control and reaction speed. By utilizing multiple temperature measurement points and analyzing temperature changes and rates in real-time, the system delivers precise temperature control.

Precise Temperature Measurement and Eco-Friendly Design

The circulator is equipped with both external and internal circulation temperature probes (PT100), ensuring precise calibration and consistent temperature control throughout the process. The equipment uses CFC- and HCFE-free refrigerants, meeting environmental standards while ensuring long-term, stable operation.

Durable and Reliable Construction

The liquid circulation and heating pipes are made from high-quality industrial-grade seamless 304 stainless steel with a thickness of 3.0MM, offering superior durability compared to standard decorative pipes. The refrigeration system utilizes a scroll compressor along with a high-temperature-resistant circulation pump, ensuring stable performance under both high and low-temperature conditions. The entire system operates with solid-state relays, eliminating sparks and noise, extending the lifespan of the equipment, and enhancing operational safety.
