-60℃ to 200℃ High Low Temperature Circulator is a compact, all-in-one recirculating chiller and heater designed for precise external temperature control. It seamlessly combines a powerful refrigeration system and an electric heater, covering a wide operating range from -60℃ (ultra‑low) to +200℃ without the need for separate cooling or heating units. This circulator is ideal for laboratory, pilot plant, and industrial applications that demand reliable temperature cycling, fast ramping, and high stability.
Ultra‑Wide Temperature Range – Operates from -60℃ to +200℃, suitable for cryogenic processes as well as high‑temperature reactions.
Integrated Heating & Cooling – No external chiller or bath required; one unit handles both sub‑ambient and elevated temperatures.
High Temperature Stability – Advanced PID control delivers stability up to ±0.05℃ to ±0.1℃, ensuring reproducible experimental conditions.
Fast Ramp Rates – Optimized compressor and heater allow rapid heat‑up and cool‑down, saving valuable process time.
Powerful Circulation Pump – Provides adjustable flow and pressure for closed‑loop external circulation to jacketed reactors, bioreactors, rotary evaporators, and more.
User‑Friendly Interface – Equipped with a 5‑inch touchscreen or keypad, programmable multi‑step temperature profiles (ramp/soak), and real‑time data display.
Comprehensive Safety – Includes over‑temperature protection, low‑liquid level alarm, auto‑diagnostics, and pressure relief valve.
Communication Options – RS485 / Modbus RTU, USB, or Ethernet available for integration with control systems and data logging.
