Safety T-Line

The RUMED® Safety T-Line offers a variable program of cold/heat and environmental test cabinets with explosion-proof test chambers for zone 1. Choose from 5 sizes and a multitude of options.

The units of the Safety T-Line are suitable for safe storage of explosive materials, such as aerosols, or for tests with adhesives or paint – even if the storage tests might occasionally or temporary cause an explosive atmosphere. Development of a permanent or long-term explosive atmosphere must be avoided by means of the option Technical Ventilation. The units are suitable for storage of material of the temperature classes T1, T2 and T3 of explosion group IIA, IIB and IIC. All appliances of the T-Line have successfully passed a demanding type examination according to annex III of the ATEX 2014/34/EU. RUMED® is a manufacturer of explosion-proof equipment being certified according to ISO 80079-34. This involves periodical inspections (audits) by a notified authority and a highly effective quality management system of worldwide importance.

Optionally available with extension of the temperature range to -20 °C/+80 °C, humidification and dehumidification and further options. Configure your test equipment, which is the most suitable for your requirements.

Technical ventilation

If an evaporation of solvents cannot be avoided by procedural means, a technical ventilation is compulsory. The ventilation prevents the formation of a permanent explosive atmosphere (zone 0). Its efficiency is supervised redundantly by two flow switches. Depending on the density, the gases will be exhausted out of the unit either at ceiling level or at floor level. The air supply is effected vice-versa, at floor level or at ceiling level, to ensure, that the air flow covers all areas of the room. The fan ensures a high ventilation rate.

Equipped with the options humidification and dehumidification, an explosion-proof cold-heat test cabinet becomes an explosion-proof climatic test cabinet. Humidification of the Safety T-Line is effected by a specially controlled ultrasonic atomizer. Humidification of the Safety X-Line is realized by an explosion-proof version of evaporation humidification being installed in the test room. A plate heat-exchanger of stainless steel, which is optimized for this application, effects a dehumidification by falling below dewpoint. This combination of humidification and dehumidification allows a wide range
of temperature/humidity combinations. The sensor is a temperature-compensated, capacitive sensor, which can be calibrated.
