Safety X- Line

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.

  • Possibility of calibration and validation
  • Robust and extremely durable

Standard Equipment - Safety X-Line

  • Switch Cabinet - Pressure-Proof Housing

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.

 

 

 

  • Digital Control

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.

 

 

 

 

  • Fan Motor

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.

 

 

 

  • Refrigerating Machine – Open Compressor with Belt Drive

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.

Option

  • 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.
Order-No.: X9990-01

 

 

 

 

  • Tubular Port

A 45 mm duct in the side panel allows insertion of measuring lines and hoses into the test room. Delivery including cover.
Order-No.: X9930-01

 
 
 
 
  • Closing Plug

Gas-tight closing plug, matching to the tubular port. The gasket system with a flexibility in the range of 4 mm to 23 mm is based on a rubber module with removable skins and can be adapted to the cables, tubes etc. in different sizes.

Order No.: X9930-02

 

 

  • Steering Rollers

Mobile version of the test cabinet with 4 steering rollers, 2 of them lock-type with brake.
Order-No.: X9930-04

 

 

 

 

  • 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.
Order-No.: X9980-01

 

  • 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.
