Multi functional constant temperature and humidity testing equipment

Multi functional constant temperature and humidity testing equipmentWidely used in fields such as electronics, communication, automotive, aerospace, shipbuilding, and chemical engineering. For example, in the electronics industry, constant temperature and humidity test chambers can be used to test the stability and reliability of various electronic components; In the automotive industry, it can be used to test the weather resistance and corrosion resistance of automotive components; In the aerospace field, it can be used to test the weather resistance and stability of various materials and components of aircraft.

Technical Specifications:

Box material: The inner liner is made of SUS # 304 8K mirror stainless steel material, and the outer box is made of SUS # 304 matte stainless steel material or A3 cold-rolled steel plate electrostatically sprayed. Install a large observation window with lighting on the box door to keep the inside bright, and use tempered glass embedded in the heating body to observe the condition inside the box clearly at any time. There is a testing hole on the left side of the box, which can be used for external testing power cords or signal testing holes. (The aperture or number of holes must be specified when placing the order). The bottom of the machine adopts high-quality fixed PU movable wheels. On the left side of the box, there are cable holes with a diameter of 50mm or 100mm for testing, which can be used for customers to conduct power on tests. There are 2 movable sample racks inside the box, and the height can be adjusted freely.

Refrigeration system: Original French Taikang fully enclosed compressor

Cooling method: air-cooled condenser.

Evaporator: fin type automatic load capacity adjustment.

Expansion system: an automatic capacity controlled refrigeration system.

Refrigerant: Adopting environmentally friendly (HFC) with zero ozone coefficient. DuPont refrigerant R404A from the United States.

Heating system: finned heat dissipation tube shaped nickel chromium alloy stainless steel electric heater. The independent cooling, circulation, humidification, dehumidification, and heating systems can improve efficiency, reduce testing costs, increase lifespan, and decrease failure rates.

Humidification: External isolated all stainless steel shallow surface evaporative humidifier, which forms wet vapor humidification through heating and detects humidity through a probe.

Dehumidification: Adopting evaporator coil dew point temperature laminar contact dehumidification method.

Water supply: Hidden water tank for water supply, small water pump automatically draws water to the humidification tank, and can recycle residual water Water conservation and consumption reduction.

Wind circulation system:

1. Adopting a multi wing centrifugal fan for strong air circulation, avoiding any dead corners, can make the temperature and humidity distribution in the testing area uniform.

2. The design of air circulation for air outlet and return ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature and humidity at the moment of opening the door.

3. Use adjustable air deflectors that can be adjusted up, down, left, and right to ensure even distribution of temperature and humidity.

Multi functional constant temperature and humidity testing equipmentAccording to the application scenario and volume, it can be divided into multiple types to meet different testing requirements:

Battery specific test box: designed for battery products, supporting high and low temperature storage, discharge cycle and other tests. The workshop capacity covers 80L~1000L, and models include BY-260A-80 to BY-260A-1000. For example, the 80L model (400 × 500 × 400mm studio size) is suitable for testing small battery samples, while the 1000L model (1000 × 1000 × 1000mm) can meet the requirements for testing large battery packs or multiple samples simultaneously.

Step in test chamber: designed for large-scale equipment or batch sample testing, with a temperature range of -70 ℃~800 ℃, supporting customized heating and cooling rates (0.7~10 ℃/min), model BY-260BR series.

Small universal test chamber: such as the 120L model, suitable for testing small products such as electronics and plastics, equipped with a three-layer insulated tempered glass observation window and an internal circulation system to ensure temperature uniformity ≤ 2 ℃.

Vertical customized test chamber: Provides customized services for shell material (stainless steel/A3 steel plate), temperature range, cooling rate, etc. The inner chamber is made of SUS304 stainless steel plate, and the insulation layer is made of high-density aluminum silicate fiber cotton to ensure a stable testing environment.
