1. It features a wide temperature working range and has both heating and cooling cycle functions. The temperature range can be customized. It is equipped with a dual-window temperature LCD display that can simultaneously show the set temperature and the actual measured value, as well as an over-temperature alarm function. It can also be optionally equipped with a second constant temperature field as a temperature control source, allowing for precise temperature control of the second constant temperature field to within 0.1℃.
2. The entire machine is designed with humanization in mind, featuring simple and quick operation, ease of use, and low maintenance costs. The refrigeration system is specially designed to start at 300℃, ensuring forced cooling in high-temperature conditions. Some models can achieve precise temperature control at any point within the range of +300℃ to -120℃. The refrigeration system uses a fully enclosed refrigeration compressor, and the circulation system uses a high-performance Olank circulation pump, which is reliable in quality and low in noise.
3. The entire machine is microcomputer-controlled and has self-diagnostic functions; it also features overload protection for the compressor, high and low pressure protection for the refrigeration system, and overheat protection for the heating chamber, among other safety protection functions.
4. The temperature control point is the heat transfer medium, and the same heat transfer medium is used throughout the entire heating and cooling process, eliminating the need to change the cold and hot media. The operation process is safe and convenient.
5. For external pressure-resistant containers, a high-flow and high-head circulation system is used to establish a second constant temperature field at a long distance.
6. For external glass containers, a pipeline pressure reduction control is adopted, effectively preventing glass instruments from breaking under high pressure.
7. The heat transfer medium circulates in a closed system. At low temperatures, the heat transfer medium can effectively avoid absorbing water vapor from the air. At high temperatures, the heat transfer medium is effectively isolated from the air, preventing oil mist formation. The isolation of the heat transfer medium from the air also effectively prevents the medium from oxidizing and deteriorating, increasing the service life of the heat transfer medium and allowing it to operate over a wide temperature range for a long time. The entire circulation system is a pure mechanical structure, safe and durable.
