Heating cooling system HR-70

Overview

The Heating Cooling System HR-70 is a closed-loop temperature control unit engineered to deliver both heating and cooling from a single device. It integrates heating, cooling, insulation, microcomputer control, and precision mechanical components into one system, providing a versatile thermal control solution for laboratory, industrial, and scientific applications. With a working temperature range of -25℃ to 200℃ and a digital control system, the HR-70 allows operators to set and maintain a target temperature across a broad span of conditions.

Performance and Design

The dual design of the HR-70 combines heating and cooling functions to provide accurate and efficient temperature control. A digital control system makes it straightforward to adjust to the desired setpoint, while the stated temperature accuracy of ±0.5℃ supports applications that demand stable conditions. The 7 kW heating output and the listed cooling capacities — ranging from 7 kW at higher temperatures down to 3.8 kW at -20℃ — give the unit sufficient capacity to handle a variety of thermal loads. The circulation pump moves fluid at up to 35 l/min through DN20 inlet and outlet connections, making the system suitable for connection to external jacketed equipment. For users who require still tighter cooling stability for routine work, a complementary unit such as the temperature precision chiller can be considered alongside the HR-70.

Applications

The HR-70 is well suited to environments where precise thermal control is essential. Typical uses include:

• Laboratories: maintaining optimal conditions for experiments and testing.
• Industrial processes: controlling temperatures in manufacturing steps that require defined thermal conditions.
• Sensitive equipment: protecting electronic devices or reactors that require constant thermal control.
• Scientific research: providing a controlled environment for studies that require changing temperature profiles.

Because the unit can circulate fluid through jacketed vessels, it pairs naturally with reactor systems used for high-temperature synthesis, allowing the operating temperature of the reactor jacket to be raised or lowered as a process demands. Operating from a 380V 50Hz supply and using R449A refrigerant, the HR-70 is a self-contained, microcomputer-controlled system for any setting where reliable heating and cooling is crucial.
