1. The low-temperature constant temperature water tank adopts a fully enclosed energy-saving compressor for refrigeration, and the refrigeration unit system adopts advanced fluorine free energy-saving refrigeration technology, which has the advantage of energy saving.

2. The refrigeration system is equipped with multiple protection devices for overheating and overcurrent.

3. Temperature microcomputer intelligent control, simple operation, good temperature stability, upper and lower limit temperature over temperature alarm, PID automatic control.

4. Large screen LCD display, adopting display standards and multiple functional icons, making it easy for users to see at a glance.

5. Intelligent microcomputer can correct temperature measurement deviation, and the temperature correction accuracy can reach 0.01 ℃.

6. Other users have adjustable PID and temperature self-tuning function.

7. There are internal and external circulation. External circulation can be used as a constant temperature liquid bath to establish a constant temperature field, or as a liquid bath for cold (heat) sources, which can reduce (increase) the temperature of the external experimental container and expand the scope of use.

8. This instrument adopts dual temperature sensors with a temperature control accuracy of ± 0.01 ℃

Low temperature constant temperature bath is an indispensable and commonly used equipment in laboratories. Widely used in scientific research departments such as petroleum, national defense, metallurgy, chemical engineering, physics, biotechnology, chemistry, medicine and health, life sciences, electronic instruments and meters, quality inspection and measurement, factory experiments, universities, research institutions, etc.

There are mainly two types of products on the market now: indoor and outdoor. Single rooms and multiple rooms can be built, and air coolers and evaporator exhaust pipes can be freely selected. For areas with high water shortage, air coolers and air coolers can be chosen. The refrigeration control system of the refrigerated truck adopts a microcomputer automatic control system, which is unmanned and stores drugs, and monitors and records the temperature and humidity of the storage area.

Refrigerated truck refers to a specialized vehicle with insulated compartments and equipped with refrigeration devices for refrigerated transportation; Thermal insulation vehicle refers to a specialized vehicle with insulation structure for short distance insulation transportation. Insulated trucks are an important component of refrigerated trucks and insulated trucks.

(1) Assemble sandwich panel adhesive type;

(2) Assembled injection foam type;

(3) Whole skeleton injection foam type. The largest domestic refrigerated truck manufacturers currently use sandwich panel adhesive methods for scattered assembly. These enterprises produce a wide variety of refrigerated trucks with large quantities and reliable quality, representing the technological level of refrigerated truck development in China and occupying most of the domestic market share; The production scale of full frame injection molded foam car manufacturers is relatively small, the production conditions are relatively simple, and the output is also limited. The product insulation performance is not high, but they are flexible and can produce various non-standard cars. There are currently many manufacturers of this type, and they have a place in the domestic refrigerated and insulated truck market.
