CHINA NBC-50L-20 Programmable High and Low Temperature Humidity chamber Temperature circulation box -20 ℃/50L

Introduction

The high-low temperature and humidity alternating Test Chamber is mainly used to test the performance of materials in various environments and to test the heat resistance, cold resistance, dryness resistance and moisture resistance of various materials. Suitable for quality testing of electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products.

Control method: Using the Balanced Temperature and Humidity Control System (BTHC), the induction system transmits the actual data in the Test Chamber to the controller. The controller controls the SSR, multi-stage intelligent output, and balances the output power of the temperature and humidity system to ensure that the temperature and humidity in the Test Chamber are The temperature and humidity are fully stable, and it has an energy-saving function, which reduces the power usage of the instrument to a greater extent and ensures long-term accurate and stable operation of the instrument.

Features

1. The product has beautiful appearance, reasonable structure, precise technology, simple and convenient operation and stable and reliable performance.

2. The controller adopts a large color LCD human-machine touch dialogue LCD human-machine interface controller, which is simple to operate, easy to learn, stable and reliable, and displays complete system operating status, execution and setting program curves in Chinese and English, and can realize RS232 Computer interface docking, remote control of the instrument directly through the computer.

3. The refrigeration cycle system uses a compressor: an original imported Japanese "Sanyo" brand fully enclosed compressor (optional French Taikang compressor). All components are imported from Japan, France, the United States, Italy and other producing areas. Refrigeration The agent uses American environmentally friendly refrigerant (R23A, R404A).

4. There is a reserved test hole with a diameter of 50mm on the left side of the test box.

5. It has a fully automatic, high-precision system loop, any machine movement, PLC locking processing, all using PID automatic calculation control, and the temperature in the entire area has high precision and high stability.

6. Specially designed air circulation system and sensing system, the air outlet and return air sensor are detected and controlled to ensure the temperature uniformity in the Test Chamber and avoid any dead spots.

7. Adopt an enlarged observation window and 4 layers of tempered glass to provide a wider field of vision.

8. The instrument has a comprehensive protection system, including power overload protection, leakage protection, control loop overload, short circuit protection, compressor protection, grounding protection, over-temperature protection, alarm audible prompts, etc. When any abnormal situation occurs, the fault will be automatically displayed on the screen immediately. Point out the reason and automatically shut down.

Structure and composition

1. Heating system

• Multi-section heating tubes are used, combined with PID modules, to ensure temperature stability; segmented heating fully saves energy.

• The heating tube is made of high temperature resistant and anti-corrosion alloy tube to extend its service life.

2. Humidification system

• The circular split humidifier avoids the freezing phenomenon that occurs with Water Tank humidifiers during low temperature testing.

• The humidification tube is made of special alloy and can be dry-heated for more than 1 hour when the instrument fails and lacks water. Together with the high-temperature alarm module, it effectively extends the service life of the humidification system. Built-in Water Tank and drawer-type water filling box are convenient and beautiful.

• Equipped with water circulation system, saving 40% water.

• It has a water quality filtration system to avoid clogging of the humidification system and reduce the frequency of cleaning.

3. Refrigeration system

• Compressor: Original imported Japanese "Sanyo" brand fully enclosed compressor (optional French Taikang compressor)

• Condenser: fin-type multi-section condenser with integral forced cooling fan

• Evaporator: fin-type multi-stage automatic load capacity adjustment evaporator, combined with energy-saving regulating valve, to achieve forced refrigeration and constant temperature refrigeration segmented control

• Refrigerant: The United States imports new environmentally friendly refrigerants R404A and R23A to achieve zero pollution to the environment.

• Refrigeration Oil: American Ice Bear Refrigeration Oil

• Filter dryer: Italian castor filter dryer,

• Solenoid valve: Japanese Lugong solenoid valve

• Copper pipes: The pipes used in the refrigeration system are all made of imported copper materials. The advantages are good flexibility and not easy to break.

• It has a better shock-absorbing effect on the long-term vibration characteristics of the refrigeration system.

4. Wind circulation system

• High resistance wind circulation motor

• Multi-wing fan blades

• Specially designed fan forced air circulation system

5. Storage rack

• Standard configuration: 1 layer (high-strength SUS304# stainless steel plate punched, single layer load 20KG)

• Shelves can be added according to customer requirements, up to 4 levels can be placed

• The shelf distance is adjustable and can be removed directly for easy operation.

6. Test chamber door

• Single door, double door, left opening

• Handle: high-strength deep buckle handle

• Hinge: high strength stainless steel material

• Sealing strip: high-low temperature resistant silicone sealing strip

• Defrost: built-in hidden defrost line

7. Test hole

There is a 50mm diameter test hole on the left side of the Test Chamber. The durability, wrapping and wire harness protection far exceed ordinary domestic (CN) materials.

8. Casters

• There are 4 high-load-bearing universal wheels installed at the bottom of the instrument.

• Adopting double wave plate design, high-quality aluminum alloy overall die-casting

• High weight, wear-resistant, shock-absorbing, smooth movement
