Fire-Rated Enclosures

Fire-rated enclosures are required in environments where it is critical to ensure continuous operation of equipment through any fire event. ITUS Global designs and manufactures enclosures up to H120 fire classes in accordance with standards such as DNV, Lloyd’s Register, IMO or US Coast Guard. As a base construction, our fire-rated enclosures are able to withstand winds of up to 225mph and up to Zone 4 earthquakes.

Base Package

3-D model of the enclosure
Seal welded construction with 10 Gauge wall panels of 48” width each
Internal stiffeners, welds, frame tubing with ability to withstand high wind loads as well as seismic events
Fire-insulated walls, doors and roof depending on the required fire protection
Fire rated insulation to meet standard on walls, doors, and roof

Mounting holes in the base channel allow fastening directly to base skid or foundation
Airflow inlet and discharge wall penetrations with fire rated dampers
Inlet and discharge weather louvers
Lifting lugs at each corner
Three-layer coating of exterior surfaces

Optional Features

The enclosure can be further enhanced to be able to withstand higher wind loads or severe environments by using alternative construction materials such as marine type aluminum or 316L stainless steel.
The building can also be designed to be blast resistant as well as purge and pressurized.
HVAC: Heating and ventilation systems inclusive of fan assembly and air-conditioning units.
E&I: Electrical items including lights, light switches, and receptacles. Power & instrumentation wiring, including such as pressure and temperature switches. Panels and junction boxes. Wiring instrumentation such as pressure and temperature switches.
Fire protection and suppression systems, including gas and flame detectors, horn and light strobes and sprinkler piping, outside/outside mounted fire suppression cabinet.
Packaging: Complete assembly of equipment, piping and fittings, valves, fuel tanks, and other components on a common skid base.

CAse Study

fire-rated enclosure

This is one a of few enclosures built for installation on a cruise ship. As such, it is in compliance with Lloyd’s Bureau requirements. The enclosure meets A60 fire-rating criteria, and provides 30 dBa noise reduction.

Some of the project highlights:

Radiator (10,000 lbs.) integrated into the roof, allowing for an easy access for any component removal given the limited space around the enclosure.
12” round corners for safety purposes.
UL-142 double wall vertical fuel tank installed inside the enclosure.
A60-certified single and double doors.
Motor-operated A60 fire-rated dampers.
Water mist eliminators.
All electrical junction boxes meet IEC standards.
