Darshields PFP

Darshield™ rigid Passive Fire Protection system is designed as a high performance solution to meet the most demanding requirements for protection of critical flow and process equipments from Hydrocarbon Pool Fire and Jet Fire conditions. Offering up to 120 minutes protection.

Darshield™ can be fitted to valves, actuators, air tanks, instrument panels and other safety critical equipment incorporating high performance thermal insulation materials encapsulated by stainless steel skins, Darshield™ is supplied in pre-fabricated panel form for assembly and installation onsite or in the factory.
Forming a rigid PFP enclosure, the panels are held together using bolts and captive nuts, with the final construction.
Providing the necessary structural integrity to withstand the specified fire and blast conditions

  • HATCHES AND PENETRATIONS

    • · It is important that the client identifies any requirements for hatches and penetrations which are approved within the Lloyds Type Approval certification for Darshield™ as early as possible such that they can be incorporated into the PFP system’s design.
    • · Darvent™ intumescent grills can be incorporated at customers request to allow for ventilation and air circulation around the protected equipment.
    • · Each Darshield™ system is engineered from equipment manufacturer drawings and checked against potential site conditions to take into account of possible space restrictions.
    • · Lloyds Type Approval certification ensures that each Darshield™ installation, inclusive of access hatches and transition points, meets with customer fire specifications.

  • DARSHIELD™ DESIGN SPECIFICATION

    • · Fire Condition - Hydrocarbon Pool Fire and Jet Fire up to 120 mins.
    • · Blast Protection: 1.62 bar
    • · Limiting temperatures for each target are determined according to the project requirements, and data from Offtranp software calculations approved by Lloyd's for each protected equipment are issued to the client.
    • · submitted in advance assessment reports, ensuring the validity of the design after individual review.

  • Combining the Darshield™ and Darmatt™ jacket PFP systems allows the fusion of the advantages of both design styles.
