Economical space-saving Ribbed Explosion Panel

Economical space-saving single-layer explosion panel suitable for low to medium vacuum applications

Dusty conditions commonly associated with the storage and handling of grains and powders can potentially lead to dangerous explosions. The robust construction of Elfab’s Ribbed design bursting panels ensures operational excellence even when low to medium levels of vacuum are present. This range of explosion vent can withstand up to 40% of the minimum burst pressure, making them suitable for many standard applications such as silos and bucket elevators. The non-torque sensitive Ribbed Explosion Vent is proving to be one of the most economic and efficient designs on the market, with its unique low profile, space-saving design.

Available on Express lead-time for improved supply chain management

The Ribbed Explosion Vent is available on an express 14-day lead-time* without additional cost.

Elfab’s outstanding in-house manufacturing capabilities and unique process efficiency means that Elfab is able to offer its customers a very quick product turn around to minimise down time in the case of an emergency. This flexibility also enhances the effective management of its customer’s supply chain. To meet the relief area requirements of a wide variety of applications, Elfab offers its Ribbed Explosion Panels in custom sizes, of either a square or rectangular construction in a wide range of bolt pattern configurations.

Economic solution with advanced quality performance

The Ribbed Explosion Venting Panel is a maintenance-free, non-torque dependent product ensuring ease and speed of installation. This combined with the low storage costs of the design ensures it is one of the most cost effective explosion bursting panels available. The standard burst pressure offering is 0.1 BarG @ 15/30°C with a 25% tolerance and wide temperature compatibility.

Optional integral burst detection for immediate shut-down

The Ribbed Explosion Vent is available with the optional benefit of an integral burst detection system for instantaneous notification when panel has burst. Elfab’s unique ATEX-approved burst detection system, Vent-Tel, was specifically designed for its range of explosion venting panels to further ensure onsite safety for its customers.

 

 

 

When connected to an intrinsically safe circuit this ExII 1GD EEx ia IIC detection device ensures a safe and compliant plat that fulfils the demanding regulatory developments within the bulk handling industry. An EC-Type Examination Certificate ITS03 ATEX 11359 is available.

Operating on a simple reed switch and magnet technology, Vent-Tel is designed to offer a practical solution for explosion vent burst detection. The magnet is pulled away from the sensor in the event of a panel burst, giving an open circuit signal. It signals a burst within the installation and in turn, can trigger an immediate shut-down of the process. Only the panel itself has to be replaced after it functions, eliminating the need to hold stock of any additional detectors or order excessive spares.

Existing Elfab explosion venting panel installations without a burst detection system can be retrofitted with the Vent-Tel system.

Exceptional in-house process capabilities to meet increasingly stringent Quality requirements.

Elfab prides itself in offering the highest level of quality and is accredited to a number of leading industry standards, these ATEX approved designs offer fail-safe rapid full venting in the event of explosion. Its outstanding On Time Delivery performance ensures that it maintains the highest customer satisfaction levels at all times.
