Cabinet oven, EB 27

Cabinet oven, EB 27

The EB 27 cabinet oven has 2 flow meters to cover the exchange rates between 3 to 200 changes per hour, but still with low air speed inside the chamber. This cabinet oven meets the requirements in ISO 188 method A, IEC 60811-401, IEC 60216-4-1, ASTM D5423 type 1 and 2, ASTM D573 and ASTM E145 type IIA.

EB 27 is a cabinet ageing oven for precision ageing of rubber and plastics under controlled conditions. The oven is supplied in one size, with 120 litres useful volume. The settings are done on the PLC colour touch screen. The air supply for EB 27 requires external air.

Elastocon’s cabinet ageing ovens have excellent temperature stability and distribution achieved by using an inner chamber with a controlled air flow. The temperature accuracy is very important for heat ageing tests, as a 1 °C error in temperature corresponds to around 10 % error in test time.

Two temperature sensors are used, one for temperature control and one for measuring the temperature close to the samples. This sensor can also be connected to a logging software.

These ovens are ideal for ageing finished products and large test pieces which are unsuitable for cell ovens. Both shelves and rods are supplied with these ovens for accommodating most types of samples.

Note: For the best performance of the instrument, we recommend a placement in an environment with a stable temperature between +10 to +30 °C.
