RUMED - Model Safety X-Linie -Cold/Heat and Environmental Test Cabinets
If ignitable mixtures exist temporarily at the installation place, highest safety standards and thus the completely ex-proof appliances of the RUMED Safety X-Line are required. They are approved for operation in explosive areas of zone 1. Despite these increased safety requirements, the RUMED Safety X-Line offers almost the same equipment possibilities as the Safety T-Line. Units of the X-Line can be installed in zone 1 and zone 2. This is possible due to a multitude of different types of protection (pressure-proof housing, intrinsic safety, increased safety, encapsulation).
All appliances of the X-Line have successfully passed a demanding type examination according to annex III of the ATEX 2014/34/EU allowing an application in zone 1 and zone 2. 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.
The units are suitable for storage and tests of material of the temperature classes T1, T2 and T3 of explosion group IIA and IIB.

Digital recorder
The digital recorder of the X-Line is working without any paper, and it can be equipped with a digital interface, just like the controller. Due to corresponding transmitters, recording and control can be executed in areas being not explosion-proof.
Tubular port
A 45 mm duct in the side panel allows insertion of measuring lines and hoses into the test room. Delivery including cover.
Steering rollers
Mobile version of the test cabinet with 4 steering rollers, 2 of them lock-type with brake.
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.
Humidification
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.
