The environmental climate Tester is a sealed space where the temperature and humidity can be controlled. Some chambers can also simulate corrosion by spraying salt into the room.
The size of these chambers varies greatly depending on the type of product that needs to be inspected. Container sizes range from 20 liters to 400,000 liters, enough to test an entire vehicle!
Function
Simulate the action of commodities we use every day in harsh climates.
For example, a car that performs well in a dry climate will not perform well in a high-humidity environment. Manufacturers can use ambient climate Testers to stress their products in a controlled environment. Ambient climate Testers allow products to be tested in continental climates with cold winters and hot summers, as well as warmer Mediterranean climates.
Ambient climate testing machines produce repeatable results when properly calibrated, simulating the output of a product over its entire life cycle. Disadvantages include that this is an energy-intensive procedure that may alter the temperature inside the Test Chamber. Ultrasonic humidifiers convert water to steam without using heat. Running water over a diaphragm vibrating at ultrasonic frequencies creates water vapor. The droplets formed by this method are so thin that they evaporate easily in the air of the Test Chamber.
Afterwards, the humidified air is delivered to the Test Chamber. In our opinion, the equipment used in the FDM climate chamber is valid.
Key Benefits of Using Ultrasound Technology
Improve humidity output efficiency
Energy performance changes
During operation, the machine is completely silent.
Working in a cold environment means no extra heat.
Instant humidity output
how to work?
The operating concept is that all conditions can be controlled manually using various mechanical processes. The temperature of the box is controlled by an electric heater or a refrigeration device.
The researchers sprayed a salt solution through nozzles inside the chamber to mimic the corrosive effects of the ocean, for example, creating a fine mist that covers the entire product.
What if the equipment in the thermal shock Test Chamber does not reach the required temperature?
Humidity in a Test Chamber can be simulated in two ways: using a heat source to evaporate the moisture or using ultrasonic technology. Steam generators that heat water and generate steam are commonly used to inject water vapor into Test Chambers. This vapor rises to the top of the environmental chamber, where it cools down again, increasing the overall humidity of the Test Chamber. This approach is beneficial because it can easily generate high humidity in large chambers.
Which products can be tested ?
It is theoretically possible to test any form of product, as any product ready for sale needs to first pass a climate test to verify functionality as required by the manufacturer or compliance with official regulatory requirements.
Aerospace, security and telecommunications are three industries that require "extreme" testing at temperatures well above or below freezing, as well as shock and vibration, due to the planned use of finished products.
Food and Beverage: Assess the shelf life, expiration date and resistance time of products when they leave the factory in optimal conditions. It also refers to packaging and the interaction between packaging and product.
Chemical/Cosmetic/Pharmaceutical: Another severely restricted application due to direct impact on human health: see our in-depth look at the pharmaceutical industry and ICH stability testing.
