Cabinet Ageing ovens for precision ageing of rubbers and plastics under controlled conditions.

ASTM E145 High Temperature Oven for Plastic and Rubber

They designed to give very low temperature variations in time and space, low air speed and controlled air exchange rate. This is achieved by using an inner chamber with a controlled air flow. Cabinet Ovens are ideal for ageing finished products and large test pieces which are unsuitable for cell ovens.

Both shelves and rods are supplied with the oven for accommodating most types of samples. The settings are done on the colour touch PLC screen. EB II is equipped with air pump and a flowmeter while EB 10 is a budget version where this is replaced by a factory set throttle to give a fixed air exchange rate of changes per hour. The Ovens can be supplied with a 3 glass window, illumination of the inner chamber and separate systems for temperature control and indication with alarm.

The ovens are supplied in two sizes, with 60 and Lt. Cabinet Oven EB II with air supply that requires external air and flow meter that can be set between changes per hour. Cabinet Oven EB II, excellent temperature stability adtm distribution is achieved by using an inner chamber with a controlled air flow. EB II is ideal for ageing finished products and large test pieces which are unsuitable for cell ovens. Cabinet Oven EB 10 II, ageing oven for precision ageing of rubbers and plastics under controlled conditions.

The oven has separate systems for temperature control and indication with alarm. EB II with aztm factory set throttle to give a fixed air exchange rate of 7 or 14 changes per hour.

Cabinet Oven EB II, ageing ast, for precision ageing of rubbers and plastics under controlled conditions and with high air speed. The oven EB II has wstm same specification and external size as EB II, except high air speed with laminar flow from bottom to top, and a reduced internal volume of 50 l. Qualitest have launched a range of ovens which incorporate a number of improvements. The most obvious difference is the use of a small PLC with a colour touch screen.

Observe that EB II needs connection to compressed air for the air exchange. We can supply a silent air compressor EA This is a cabinet ageing oven with high air speed 50 lit inner volume and a carousel inside the cabinet for mounting of the samples. Included is window in the door, lightning inside the chamber and door sensor that turns off the fan, heating and carousel when the door opens. The carousel has room for up to 36 samples.

This oven meets the requirements in ISO method D145. This is an ageing oven with high air exchange rate. This oven is based on our liter EB 04II oven. Observe that EB 27 needs connection to compressed air for the air exchange. EC 11 Monitor Software Network cable. Qualitest manufactures sstm range of ageing ovens for precision ageing of rubbers and plastics under controlled conditions. The ovens are designed to give very low temperature variations in time and space, low or high air speed and controlled air exchange rate.

Good control of temperature, air speed and air exchange rate has been shown to be very important to achieve good repeatability and reproducibility when doing heat ageing tests of polymer materials.

Our research shows that the air speed is a very important factor, influencing the ageing results by increased evaporation of softeners and antioxidants and by increased oxidation at higher air speeds.

All ageing ovens have a touch screen control utilising a micro PLC. Improved Ageing Ovens Qualitest have launched a range of ovens which e1145 a number of s145. Some of the improvements are: New touch screen atm utilising a micro PLC. Test names can be given in the PLC. Improved door with new hinges and two point locking. Easier shelf installation and removal.

E Standard Specification for Gravity-Convection and Forced-Ventilation Ovens

Special design with controlled air exchange rate and low or high air speed. The casing consists of steel, painted with epoxy powder paint in blue green colour. The inner chamber is made of stainless steel.

Temperature controller with 0. Solid state relay for safe control. Temperature indicator with sensor in the inner chamber. Fixed over temperature fuse. Cooling channels in the casing for low surface temperature. Controlled cooling fan for the electronics cabinet. Indication of power failure PLC. EB 27 This is an ageing oven with high air exchange rate.

The ovens perform well inside the apparatus requirements in referenced standards. Special design with controlled air exchange rate and low air speed. The casing consists of steel, painted with powder paint in blue green color.

The air speed is low and is dependent on the atm exchange rate only. EB 27 Cooling channels in the casing for low surface temperature. Indication of power failure. Count up and down time PLC.
