Jiahang JH-1200 cooling water circulation device adopts non-start-stop refrigeration technology, which is designed and manufactured to provide professional technical indicators and reliability in the industry, and is a high-precision and high-stability cooling equipment; The equipment adopts a fully enclosed refrigeration system, combined with PID temperature control, fast refrigeration, stable temperature, and meets some requirements for precision and constant temperature cooling equipment.
1) Adopt electronic expansion valve technology to control temperature, non-compressor start-stop type, reduce the damage to the compressor, and save 20% of electric energy;
2) Automatic detection of high-low water levels, automatic prompting of liquid addition when low a certain value;
3) The imported compressor has low sound and high refrigeration rate.
1. The refrigeration system adopts imported Taikang compressor to ensure the refrigeration capacity and reduce the minimum noise at the same time.
2、PID temperature control technology is adopted. Refrigeration is not a traditional compressor start-stop type, and the use of electronic expansion valve technology greatly improves stability.
3、The refrigeration control system has its own temperature overrun protection and automatic alarm function, which fully prevents the damage of the constant temperature medium caused by low or high temperature value of the bath liquid.
4、With water level observation window and automatic water level detection device, the buzzer will automatically alarm if the water level is too low.
5、The automatic water flow detection device is convenient for automatic switching to internal circulation when the external circulation is blocked.
6、High-performance circulating water pump, which can maintain continuous work for a long time, good sealing and no leakage. The Circulating Chiller pressure is 0~1.5par, which can be adjusted by knob and displayed by pressure gauge. Enjoy a more intuitive operating experience.
7、The color LCD screen display shows more data information and dynamic identifiers, so that you can see the running status of the instrument at a glance.
