Product description

Features

  • Explosion protection in accordance with ATEX.
  • Ex II 2G Ex e IIB+H2 T3/T4 Gb.
  • For usage temperatures of -20°C ≤ Ta ≤ +40°C.
  • MAICO Ex fans fulfil the safety requirements of European Directive 2014/34/EU for units and protective systems in explosion-endangered areas.
  • For zone 1 and 2.
  • Duct sleeve made of galvanised sheet steel, with flanges on both sides.
  • Can be fitted in any position.
  • Can be switched to ventilation or air extraction.
  • Reversing mode: The volumetric flow is reduced by approx. 35 % with abnormal air flow direction.

Motor

  • Robust motor with ball bearings, maintenance-free.
  • Motor protection class IP 54.

Electrical connection

  • Separate terminal box, explosion proof, with cable screw-connections.

Required safety technology

  • A PTC thermistor triggering device is needed to fuse the DZR-Ex e units.
  • Maico provides the MVS 6 PTC thermistor triggering device and TMS for this purpose.
  • MVS 6 PTC thermistor triggering device
    • Independent complete system.
    • For monitoring the maximum motor temperature.
    • Type-examination tested according to Directive 2014/34/EU (ATEX).
    • Installation exclusively in non-explosive areas.
  • TMS PTC thermistor triggering device
    • For monitoring the maximum motor temperature.
    • Suitable for installation in control cabinets.
    • Type-examination tested according to Directive 2014/34/EU (ATEX).
    • Installation exclusively in non-explosive areas.

Safety instructions

  • Speed control permitted with transformer TR.... Exception: DZ.. 35/2 B Ex e
  • The temperature in the fan unit is monitored by PTC thermistors. The PTC thermistors must be connected to a triggering system (safety device according to Directive 2014/34/EU), that separates the fan permanently from the power if the temperature gets too hot.
  • The MAICO PTC thermistor triggering device MVS 6 or TMS is recommended as the triggering system.
  • The fan may be operated only if the protection against accidental contact with the impeller is guaranteed to be in accordance with DIN EN ISO 13857 for fans with free inlet and outlet, e.g. with an SG protective grille.

Special versions

  • Special voltages are available on request, at an extra cost.
  • Information on operation at temperatures occasionally below -20°C available upon request.
  • Feasibility must be checked in each case.
