Ex-proof Equipment-Line Safety T and Safety X

Working safe with RUMED®: If explosive material is to be tested or if the installation place is exposed to the danger of explosions, the RUMED® Ex Equipment-Lines ensure highest safety. All appliances of the X-Line and 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.

Two executions are available: In the Safety T-Line, the test chamber is explosion-proof, in the Safety X-Line, the entire unit is explosion-proof. The units of the Safety X-Line can also be used in explosive areas of zone 1 and zone 2, such as in refineries or chemical plants.

All units are manufactured from stainless steel. Thus, they are resistant to solvents and chemicals. Material and processing guarantee easy handling and durability. The explosion-proof recirculating air fan provides a good temperature distribution in space, as well as quick heating and cooling. If the door had been opened, the initial temperatures will be achieved within the shortest time.

RUMED® Ex Equipment fulfils various tasks in the chemical and petrochemical industry, in the pharmaceutical production, for stability tests, as well as in the laboratory.

  • Stability tests of pharmaceutical products
  • Storage of aerosols
  • Storage of solvents
  • Drying of coatings containing solvents
  • Drying tests on adhesives and paint
  • Temperature and storage tests of aerosol cans.

  • Temperature-conditioning of solvents.

  • Curing of adhesives and paint under defined climatic conditions.

Explosion groups

Explosion group IExplosion group II
Electrical equipment for use in mining operations with a firedamp risk, e.g. coal-mining: coal dust, methane gasElectrical equipment for use in all areas with an explosion hazard, other than mining operations with a firedamp risk, e.g. the chemical industry: paints, acetylene


Making the right choice – Selection criteria for electrical equipment

Ex zone gases, vapors, mists (EN 60 079-10)Unit categoryA dangerous, potentially explosive atmosphere ...No effective ignition source ...
Zone 01G... is present either conti­nously or for lengthy periods (>1000 hours/year)... in fault-free operation, for rare operational faults or in the event of frequent operational faults
Zone 12G... only occurs occasionally (10 - 1000 hours/year)... in fault-free operation or with frequent operational faults
Zone 23G... less than 30 minutes per year... in fault-free operation


Temperature classes in explosion group II

Temperature classMaximum permissible surface temperature of the equipmentIgnition temperature of the flammable material
T 1450 °C> 450 °C
T 2300 °C> 300 °C ≤ 450 °C
T 3200 °C> 200 °C ≤ 300 °C
T 4135 °C> 135 °C ≤ 200 °C
T 5100 °C> 100 °C ≤ 135 °C
T 685 °C> 85 °C ≤ 100 °C
