The TR series of ovens has a maximum working temperature of up to 300 °C, horizontal forced air circulation and achieve a temperature uniformity better than ±5 °C. TR 30 to TR 240 units have been designed as bench top models, TR 450 and TR 1050 are floor standing models. Units have a large, wide-opening swing door, hinged on the right with quick release for models TR 30 - TR 450 and double swing door for TR 1050 models. A large door handle and AISI alloy 304 (DIN material no. 1.4301) stainless steel chamber, which is rust-resistant and easy to clean. They can be used for various applications such as e.g. drying, sterilising or warm storing. TR 1050 models feature transport rollers as standard, these can be ordered as an option for TR 450 models.
