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. Yearly inspections (conformity of the type, annex VI of the ATEX 2014/34/EU) by a notified authority ensure the high quality and safety requirements.
The units are suitable for storage and tests of material of the temperature classes T1, T2 and T3 of explosion group IIA and IIB.
The switch cabinet is equipped with a pressure-proof housing. Thus, large part of the electric system can be manufactured using standard components. This pressure-proof housing „d“ according to DIN EN 60079-1 effectively avoids inflammation of the atmosphere surrounding the switch cabinet.
Operation and control of the appliances is effected by means of the modern, digital control unit. A digital interface for this control unit is optionally available. The option Program Control allows complex, several days‘ programs with cyclizations and loops.
Up to a working temperature of 35 °C, the fan and the integrated motor are located in the test room. For higher working temperatures, the motor driving the fan wheel in the test room will be installed outside the appliance. In any case, the motor will be disconnected permanently by a protective motor switch in case of a failure.
The open refrigerating machine is driven by a conductive V-belt and a motor with pressure-proof housing. The explosion-proof solenoid valve bypass system ensures precise control. The refrigerating system is protected against malfunction by an explosion-proof pressure switch, as well as by a protective motor switch.
