TTX Large Format Windows

Keep energized electrical equipment closed during inspection, and easily comply with OSHA, NFPA 70E, CSA Z462 and similar electrical safety mandates.

Closed-panel inspections eliminate inherently high-risk tasks, such as removing panels or opening hinged doors, making your work processes safer for personnel, plant assets and processes.

The more efficient work process can reduce inspection costs by 75% to 95%, while improving worker safety.

3 Inspections, 1 Window
The TTX series is a Multi-Inspection Panel that combines a large format infrared (IR) window, with a visual inspection window and (optional) ultrasound ports.

The innovative design allows technicians to take IR and ultrasound scans while performing a visual inspection or taking digital photos through the same inspection panel while de-risking their predictive maintenance work process.

Access the Inaccessible
Does your facility have equipment with voltage or incident energy ratings that are now declared “off limits” by your Electrical Safety Program? How do technicians inspect equipment that must be kept closed or is protected by switched interlocks? Turtle Tough Large-Format Inspection Panels provides safe access to “inaccessible” energized equipment.

Compliance Made Easy & Quick
OSHA, NFPA 70E, CSA Z462 and similar electrical safety mandates do not require additional PPE when equipment remains closed and in “Normal Operating Condition.” Closed-panel inspection methods, like those made possible with XDP Series Large-Format Inspection Windows, are an easy way to comply with evolving mandates.
Performing inspections through an IR window or visual inspection window eliminates inherently high-risk tasks, such as removing panels or opening hinged doors. The resulting work task is safer for personnel, plant assets and processes. Routine inspections can now be performed while energized equipment is kept closed, and in “normal operating condition” in compliance with electrical safety standards and mandates.

Save Time, Save Man-Hours, Save Money
Using inspection windows eliminates the need for constant dressing up and down in PPE, and it eliminates the need to tie up highly-skilled personnel to needlessly open and close equipment. Simply put: it’s a vastly more efficient use of man-hours. In addition to the obvious safety benefits, time studies have demonstrated that using inspection windows can also reduce inspection costs by 75% to 95%.

Over-Engineered for Your Safety
The TTX is built to outlive your enclosure. You have to see it to believe it.
The panel is fabricated from 12 gauge stainless steel and the cover from 16 gauge stainless steel. When it comes to durability and brute strength, Turtle Tough is without peers.

Analyze Better Data
Because using inspection windows does not increase risk of electrical hazards, inspections can be performed during peak load, when data collection is ideal, without worry of accidental process interruption.

Window Anatomy

Visual Inspection Window

  • Viewing window provides a broad field of view inside the enclosure, even across phase dividers
  • Impact-resistant polycarbonate: the durability and resilience you expect from Turtle Tough
  • Scratch-Off™ protection inside & out: peel scratches and hazing of the viewing window for a clear, accurate view with Turtle Tough patent pending multi-layer tear-away system
  • UV stabilized, oil resistant.

Infrared(IR) Window

  • IR window optic provides a vast field of view without cropping issues
  • Impact-resistant optic for unsurpassed durability
  • Finger guard allows a user to place camera lens next to window optic to maximize field of view
  • Polymer optic is inherently resistant to moisture, humidity, and a broad spectrum of acids and alkalis for longevity and stable transmission
  • Transmission throughout the entire long wave and mid wave spectra for accurate temperate and ΔT calculations

Window Body & Cover

  • 12 gauge stainless steel base, and 14 gauge stainless steel hinged cover for unmatched durability and integrity
  • Window frames machined from bar stock aluminum — Mil-Spec anodized
  • Stainless steel, spring loaded captive cover screws for a safe, secure seal
  • Entire assembly powder coated to endure aggressive environments
  • Cover available in full or partial (IR only)

Other Structural Features:

  • Stainless steel reinforcing plate (inside the enclosure) ensures a tight, flat seal in the event of blast forces
  • Stainless steel studs with Nyloc nuts ground and anchor the window into virtually any enclosure
  • Gaskets between the cover and body, and between the body and enclosure provide a NEMA 4X seal for indoor and outdoor use
