Technical innovation of Haozhuang low temperature thermostat circulator

Shanghai Haozhuang Instrument Co., Ltd. has developed the LNB brand low-temperature constant temperature circulator, which is energy-saving, environmentally friendly and domestically leading. Professional manufacturing is more secure and affordable

Technological innovation: 1. Immersed controller adopts fuzzy logic PID control, high-brightness LCD display, which can display the time and date and the information of the current system of the equipment, simple and clear, and convenient for user operation. 2. Easy maintenance, convenient for user maintenance, clean Condenser, improve refrigeration performance, save energy. 3. RS232 interface PC dedicated interface, a dedicated software CD (applicable to Simplified Chinese WINDOWS2000 or Simplified Chinese WINDOWS XP operating system) through the PC dedicated software to prepare test procedures and monitor and save. Directly display and print the test data through the PC-specific software. 4. Convenient to discharge liquid. Convenient to discharge liquid, easy to clean and maintain in the box. 5. Uniform temperature adopts the design of the surrounding condensing coil, uniform cooling and heating is beneficial to ensure uniform temperature in the box. 6. Humanized handle professional human mechanics principle design, improve user comfort. Application range: widely used in pharmaceutical, chemical, medical, scientific research and other industries for various research machines, analysis and measurement equipment and industrial machinery Low temperature cooling and temperature control of the hot parts.

Advantages: â—† The box body is made of high-quality cold-rolled sheet and customized special DuPont powder spray treatment. The inner tank adopts SUS304 stainless steel plate, laser cutting processing technology, the surface is smooth and beautiful. â—† The main components imported from abroad (circulating water pump, leakage protector, control system, sensor ...) have superior performance and reliable quality. â—† The temperature range of the combined use of the freezer and the heater is wide, the temperature control is more precise, and high-precision temperature adjustment is possible. â—† Strong external circulation and cooling capacity, and the pump power is electronically adjustable, which can ensure the best circulation heat exchange effect. â—† The air inlet at the bottom of the control panel is equipped with an air filter to effectively prevent dust inhalation and maintain the internal cleanliness of the equipment. â—† This product adopts fuzzy PID control, high-brightness LCD large display screen, which can display the time and date and the current system information of the equipment, easy to operate. â—† With leakage protection, power failure recovery, water level alarm, independent over-temperature protection, temperature upper and lower limit alarm and other devices to ensure safer equipment operation.
