Industrial Test Chambers

Product Details:

Ozone is a highly reactive and unstable form of oxygen that is present in small concentrations in both the stratosphere and the troposphere. It plays an important role in the atmosphere, resulting in both beneficial as well as detrimental effects on both living and non-living things. The stratospheric ozone protects the living beings and the environment from the harmful rays of sun, whereas the troposphere ozone or ground level ozone is highly toxic for living beings and is notorious for causing material damage and corrosion. The ground level ozone usually results due to the interaction between atmospheric pollutants and the sunlight, though a small amount is also contributed from the overlaying stratosphere. The concentration of ozone varies from one place to another and within the same environment from time to time. However, with an increase in population and rapid industrialization, the concentration of ozone has been gradually increasing over the past few years. This ozone, being a powerful oxidant, often leads to significant material damage, resulting in economic losses due to increased cost of production and maintenance. The ozone climatic test chambers are often employed by industrial units and research organizations to study the effect of ozone exposure on the aesthetics and functional value of various products, including plastics, rubber, paint, fabrics, metals etc.


Features:

The Ozone Test Chamber provide an effective solution to the testing of products for resistance against ozone degradation in a controlled environment. These test chambers function as static tensile test chambers as well as Rubber Test Chamber and are often used for studying static tensile deformation of various manufactured goods in the presence of ozone. The equipment works by exposing the test samples to uniform concentrations of ozone at constant temperatures and relative humidity in a sealed air environment. Under these conditions, the products undergo the process of corrosion which can be observed in the form of surface cracks and changes in other properties.

The ozone climatic test chamber from Weiber are compact and easy to install equipments that are designed for economical and versatile applications. The equipment uses high quality construction materials such as imported hi-class stainless steel plates for the inner bladder and plastic coated A3 steel plates for the outer bladder of the test chamber for a sturdy and reliable construction. The equipment also features an inbuilt 360° rotating sample rack with multiple sample locations. The rotary working table uses an aluminum alloy table board for increased corrosion resistance. All the internal surfaces are made up of copper or stainless steel for smooth and easy to clean surfaces. The roof of the test chamber is also provided with balance exhaust holes that help in maintaining the concentration of air and ozone within the working area.

The Weiber ozone climatic test chamber are designed for both static and dynamic tests, with or without rotation. These self-contained units are frequently used for testing the dynamic stretching of rubber and are often used as accelerated ageing test chambers for rubber.

These drying chambers are available in various standard sizes and can also be customized to suit specific requirements.

 

The Weiber Tray Drying Chamber manufacturers have made these chambers easy to operate, low maintenance equipments that are designed for highly safe, reliable and economical operation. They consist of an insulated cabinet, fitted with trays for holding the sample to be dried. The drying chambers are double walled units that feature high grade SS 304 stainless steel interiors and external walls made up of powder coated, rust proofed thick PCRC sheets. The internal walls feature fully welded surfaces, ensuring smooth, easy to clean and leakage proof surfaces. The gap between the walls is filled with high quality mineral glass wool fibrous insulation or PUF cellular insulation for maximum thermal efficiency. The equipment uses sheathed air heaters for indirect heating of the chamber and efficient fans and motor for maintaining a continuous air circulation for uniform distribution of heat. The fans and motor are designed for minimum vibration and low noise operation.

 

Features:

The Tray Drying Chambers use gas circulation method for drying of the samples. The equipment uses an air inlet to allow the entry of fresh air within the chamber, which is then drawn by the fan through the heater coils. The heated air is then blown across the sample specimens and is exhausted outside through the exhaust air outlet. The air inlet is provided with screen filters that filter out all the dust particles and other contaminants, preventing them from entering the drying chamber. The air inlet and exhaust outlet are positioned at considerable distance from one another to prevent the suction of used, moisture laden air back into the circulation. The recirculating designs that permit the recirculation of air within the chamber use a desiccant or cold plates/coils for removing the excess air moisture prior to its recirculation for maximum drying efficiency. The Weiber tray drying chambers are also provided with additional heaters and fans that are strategically placed within the drying chamber to ensure uniform and adequate heating of the samples irrespective of their placement within the unit. The equipment may also use perforated sample trays to allow penetration of upwardly mobile hot air through the sample material via the tray holes for faster drying.

 

The Weiber tray drying chambers are also provided with a vacuum pump to facilitate the extraction of water vapour and vapours of solvents from the samples to be dried.
