Overview

The nVent FS66S Freestand Dual Access Enclosure (SKU: FS180654DHP0) is a premium-grade, 304 stainless steel industrial housing engineered to protect critical electrical and electronic components in the most demanding environments. Designed for outdoor and indoor applications where corrosion resistance, durability, and modular flexibility are paramount, this enclosure delivers unmatched performance for mission-critical systems. Built to withstand extreme temperatures, moisture, chemicals, and mechanical stress, the FS66S is a trusted solution across oil and gas, water/wastewater, petrochemical, power generation, and distributed control system (DCS) installations worldwide. At the heart of the FS66S’s versatility is its **ProLine modular interior rail system**, which enables effortless customization for rack mounting, panel mounting, or grid system integration. This adaptability allows engineers and technicians to configure the enclosure’s interior layout to accommodate a wide range of components—from motor starters, variable frequency drives (VFDs), and contactors to programmable logic controllers (PLCs), relays, and power distribution units. The dual-access design ensures easy front and rear access for maintenance, troubleshooting, and upgrades, significantly reducing downtime in high-availability applications. Constructed from **Type 304 stainless steel with a brushed finish**, the FS66S offers exceptional resistance to corrosion, rust, and staining, making it ideal for coastal, chemical, or high-humidity environments. Its robust 4x 12-gauge construction provides structural integrity and impact resistance, while the freestanding design simplifies installation on uneven or elevated surfaces without the need for additional mounting hardware. The enclosure’s dimensions (1879 x 618 x 515 mm) provide ample internal space for large-scale assemblies, and its modular design allows for future expansion as system requirements evolve. Industries such as oil and gas, where equipment is exposed to harsh chemicals and volatile conditions, rely on the FS66S to safeguard sensitive electronics and control systems. In water/wastewater treatment plants, the enclosure’s corrosion-resistant properties ensure long-term reliability in chlorinated or high-moisture environments. Petrochemical facilities benefit from its ability to resist hydrocarbon exposure and extreme temperature fluctuations, while power plants use it to house DCS components that demand both protection and accessibility. The FS66S is also a preferred choice for renewable energy installations, such as solar and wind farms, where outdoor-rated enclosures must endure prolonged exposure to the elements. nVent, a global leader in electrical and thermal management solutions, designs the FS66S with the same engineering rigor applied to its entire portfolio of industrial enclosures. Backed by decades of expertise in harsh-environment applications, nVent ensures that every FS66S enclosure meets rigorous quality standards, including UL and NEMA certifications for safety and performance. Professionals in electrical engineering, automation, and industrial maintenance trust nVent enclosures for their reliability, compliance with industry regulations, and ease of integration with existing systems. Whether specifying a new installation or retrofitting an aging system, the FS66S provides a future-proof solution that balances durability, flexibility, and long-term cost efficiency.

How to Safely Handle and Install Large Hoffman Enclosures

This guide provides instructions for safely handling and installing large Hoffman enclosures, emphasizing precautions to prevent injury and equipment damage.

Estimated time: 1h

Tools needed:

Forklift, Overhead lifting device (e.g., crane), Slings with load-rated hooks or shackles, ROLL•A•LIFT™ or similar device (for some models)

Supplies needed:

3000 lb.-rated chain or strap (for securing to forklift mast), Rigging equipment (for overhead lifting)

  1. Read Safe Handling Requirements

    Before moving or installing the enclosure, thoroughly read and understand the 'Large Enclosure Safe Handling Requirements' document that accompanied the enclosure. Ensure the route is clear of obstructions and all personnel are at a safe distance.

  2. Prepare for Movement

    Ensure the enclosure is stabilized before removing any strapping. Verify that the lifting equipment (forklift or overhead device) has a sufficient load rating for the enclosure's weight and size. Only trained and authorized personnel should operate the lifting equipment.

  3. Position Forklift Forks

    For forklift handling, spread the forks to the maximum distance or as dictated by the skid width. Enter the skid from the rear (Side A) of the enclosure. Position the enclosure carefully on the forks, keeping the load against the carriage/mast and tilting the load backward towards the mast.

  4. Secure Enclosure to Forklift

    If using a forklift, secure the enclosure to the forklift mast before moving. Insert a 3000 lb.-rated chain or strap through the eye bolts provided on top of the enclosure and fasten it securely to the forklift mast assembly. Ensure sufficient tension to prevent tipping.

  5. Lift and Transport Enclosure

    Lift the enclosure a minimum distance so the skid is just clear of the floor. Start and stop the forklift slowly and gradually, avoiding jerky movements. Drive slowly with the forks carried as low to the ground as possible. Never attempt to move more than one enclosure at a time.

  6. End Loading/Unloading (if applicable)

    For end loading/unloading on trailers, spread forks to match pallet end slot openings and enter from the narrow side (C or D). Secure the enclosure to the forklift mast using chains or straps. Tilt the mast to take weight off the opposite end and slide/push the enclosure as required. Do not use chains or straps to lift the enclosure.

  7. Overhead Lifting (if applicable)

    If using overhead lifting, attach rigging to the eye bolts, ensuring the angle between lifting cables and the vertical does not exceed 45 degrees. Use slings with adequate load-rated hooks or shackles. Ensure the load rating of the lifting device and rigging is sufficient. Do not use ropes or cables through eye bolts.

  8. Final Placement

    Once the enclosure is at its final location, carefully position it. Ensure it is stable and permanently installed according to any specific product instructions not covered in this general handling guide. Refer to the nameplate or datasheet for model-specific details.
