Ningbo Guante Refrigeration Technology Co., Ltd. is a scientific and technological entity dedicated to the development, production and sales of experimental equipment, petrochemical equipment, API production equipment and short range molecular distillation equipment. Products are exported to Europe and the United States, the Middle East and other countries (customized voltage of three-phase 220 V 60 Hz and three-phase 480 V 60 Hz).
The liquid circulation of the entire system is airtight. The system is equipped with an expansion vessel. The expansion vessel and the liquid circulation are adiabatic and do not participate in the liquid circulation. They are only mechanically connected. Regardless of whether the temperature of the liquid circulation is high or low, the medium in the expansion vessel is low. At 60 degrees.
The entire liquid circulation is a closed system, there is no absorption of water vapor at low temperatures, no oil mist is produced at high temperatures, and the heat transfer oil can have a wide operating temperature; no mechanical and electronic valves are used in the entire circulation system.
◆Wide working temperature range, with heating and cooling function at the same time, the maximum temperature range: -30~180 degrees.
◆The controller with 2 LED displays can simultaneously display the temperature set value and actual value, as well as the over-temperature alarm value.
◆Efficient and fast, easy to fill liquid.
◆Ensure rapid cooling under high temperature conditions; continuous temperature control from 180 degrees to -25 degrees can be achieved.
◆Circulation management is fully enclosed, and there is no oil mist and water absorption, which ensures the safety of the experiment and the life of the thermal fluid.
◆The refrigeration unit American Gulun compressor and circulating pump have stable performance and reliable quality.
◆With self-diagnosis function; refrigerating machine overload protection; high-pressure pressure switch, overload relay, thermal protection device and other security functions.
◆High-lift design to meet the requirements of long-distance transportation of heat-conducting media.
◆Adopt R404A environmental protection refrigerant to meet environmental protection requirements.
