Dust explosion protection in Europe

Explosion-proof doors

Producer: RSBP

The explosion-proof door (panel) is a basic and economical method of passive protection of process equipment in the event of an accident in accordance with EN 1127-1.

During the normal course of the production process, the panel closes the explosion relief opening. During an accident, the pressure in the equipment to be protected rises. When it reaches a certain value, the panel opens and releases the explosion shockwave to the outside. The pressure is reduced to values that are safe for the equipment and the structure is not destroyed.

Description

The EX DOOR explosion-proof panel is a galvanised steel magnetic construction, designed for repeated use. It can be equipped with a seal to ensure dust-tightness and an open/close indicator.

The blast panel is suitable for process equipment with a low operating pressure, up to 0.7 bar, and which is not resistant to pressure rises. It opens at 0.1 bar as standard, but can be adjusted to the customer’s process conditions. The blast door is not used where pressure surges can occur.

  1. The panel activates on pressure rises up to 0.1 bar, so it can be used on pressure-sensitive equipment. The explosion plate can be adapted to the specific process equipment.
  2. Easy to assemble – assembly in only two steps, according to ready-made drawing kits and assembly instructions.
  3. Easy to maintain – we will provide a detailed operating manual, which describes the frequency of all operations. The customer’s employees are only required to visually inspect the cleanliness and integrity of the blast panel.
  4. Installed without altering the design of the existing process equipment.
  5. Reusable, so there is no cost for consumables and accessories.
  6. Service is only required once a year, which also reduces operating costs.

Installation

The safety rupture disk must be checked before installation:

  • Integrity of the original packaging;
  • The membrane itself and the seals are undamaged;
  • The connecting material is present, if it is included in the scope of delivery;
  • No damage to the indicator, if ordered.

The rupture discs are installed in accordance with the manufacturer’s instructions and the explosion protection project. The work consists of two basic steps. First, the mechanical installation is performed, followed by the installation and adjustment of the electrical part.

The installation of each membrane must be recorded in a special logbook or operating book with the date, initials and signature of the authorised person.

The scope of delivery includes:

  • Consignment note
  • EU Declaration of Conformity 2014/34/EU
  • Inspection certificate
  • Operating instructions

We will provide on request:

  • wiring diagram of the indicator;
  • technical description of the opening indicator;
  • technical description of the spark protection relay;
  • Panel wiring diagram;
  • Checklist;
  • The operating logbook.
Maintenance

The maintenance manual is included in the scope of delivery and is used as a basis for the operator’s documentation. In this manual, the maintenance intervals are determined.

Maintenance of the membrane consists of periodic inspection for cleanliness and damage, corrosion. Basic rules:

  • All operations must only be carried out with the equipment switched off;
  • Check the panel every shift for cleanliness and damage;
  • Perform dusting and screw connection checks at least every six months or more frequently depending on the operating conditions;
  • Instruct employees on safety measures when working near the explosion panel immediately after its installation (when a new employee is hired) and at least once a year thereafter – the EX DOOR is classified as injury-prone equipment;
  • Do not enter the frame and safety area when the equipment is in operation.

Only the manufacturer – RSBP or its authorized representative – can provide service maintenance for the explosion-proof door. The frequency of maintenance should be no less than once a year.
