Trellchem AlphaTec Type TR (1b) Orange L/45 Chemical Suit

TRELLCHEM® / ALPHATEC® TYPE TR (TYPE 1b) GASTIGHT CHEMICAL SUIT – ORANGE (SIZE L / BOOT SIZE 45)

The Trellchem® AlphaTec® Type TR (Type 1b) is a non-encapsulating, reusable gas-tight chemical protective suit engineered specifically for high-consequence shipboard operations, offshore drilling rigs, chemical tankers, and land-based HAZMAT response teams. Designed to provide Type 1b barrier integrity, the Type TR configuration utilizes an external self-contained breathing apparatus (SCBA) arrangement, keeping positive-pressure air cylinders outside the chemical barrier while securing full isolation via an anatomical, chemically resilient rubber face seal.

Constructed from dense, tightly woven polyamide/polyester fabric hot-melt coated symmetrically on both sides with high-grade plasticized polyvinyl chloride (PVC) and joined using high-frequency dielectric double-welded seams, this garment prevents molecular permeation of alkalis, industrial acids, toxic liquids, particulate aerosols, and vapor-phase industrial contaminants. Integrated with heavy-duty size 45 yellow PVC safety boots via an ergonomic clamp-ring system, the Type TR delivers continuous grounding continuity (antistatic to EN 1149-5) and mechanical cut/puncture endurance required for confined space entries in marine machinery spaces and chemical cargo holds.

Technical Details

Features

1. EN 943-1 Type 1b Gas-Tight Architecture: Protects the wearer against aggressive airborne gases, toxic vapors, liquid aerosol jets, and solid chemical particulate hazards in demanding industrial sectors.
2. Dielectric Radio-Frequency Welded Seams: Eliminates needle penetrations and mechanical thread weaknesses through continuous, high-tensile RF fusion across all panel joints.
3. Modular Bayonet Glove & Boot Ring Clamping: Features quick-disconnect locking rings that enable rapid offshore replacement of breached chemical gloves or worn safety boots without retiring the main suit body.
4. Ergonomic External SCBA Configuration: Low-profile back contour without an equipment hump provides exceptional maneuverability through tight marine escape trunks, vertical ladder ways, and hatch coamings.
5. Inherent Static Dissipation & Biosecurity: Surface-resistive formulation complies with EN 1149-5 for flammable zone entries while satisfying EN 14126 resistance to biological pathogens and viral agents.

Equipment Compatibility

• Dräger (PSS 3000, PSS 5000, PSS 7000 Series with Panorama Nova or FPS 7000 face pieces)
• Scott Safety / 3M (SABRE, Contour, ProPak Series with Promask or Vision 3 face masks)
• Interspiro (Spiroguide, QS II, Incurve with Spiromatic masks)
• Honeywell / Fenzy (Aeris, X-Pro Series)

Applications

• Chemical Tankers & Product Carriers: Emergency response and cargo system leak remediation for IMO Type I, II, and III liquid chemicals.
• Engine Room Emergency Operations: Interventions during refrigeration system ammonia ruptures, boiler chemical dosing spills, and bunker fuel line breaches.
• Offshore Oil & Gas Platforms: Hydrocarbon separation area maintenance, crude processing gas-tight entries, and hazardous chemical injection skid repair.
• Industrial Spill Response (HAZMAT): Municipal Hazmat operations involving low-to-medium concentration inorganic acids, alkali washdown solutions, and pesticide decontamination.
• Confined Space Tank Cleaning: Bilge, ballast, fuel storage, and chemical washing tank inspections where physical abrasion and high liquid-volume splash risks coexist.

Frequently Asked Questions

What is the core operational difference between a Type 1a and a Type 1b chemical suit?

A Type 1a suit features an encapsulating hump design where the SCBA and face mask are worn completely inside the suit. A Type 1b suit, such as the Trellchem AlphaTec Type TR, is non-encapsulating; the user wears their SCBA cylinder harness outside the suit, while the full-face mask seals directly through the suit’s anatomical rubber face seal. Type 1b suits provide superior physical mobility and narrower clearances in tight corridors, bulkheads, and confined ship compartments.

Can the integrated safety boots and gloves be replaced on the AlphaTec Type TR?

Yes. The suit is equipped with factory bayonet ring systems on both the sleeves and the boots. If a glove or boot suffers physical puncture, chemical degradation, or sizing requirements change, the integrated clamp ring allows complete replacement with new components without voiding the suit’s sealed seam integrity.

Is the Trellchem AlphaTec Type TR suitable for cryogenic or flash-fire environments?

No. The Type TR is constructed from PVC-coated polymer fabric, which provides resistance across acids, bases, biological agents, and industrial solutions, but is not designed for cryogenic liquids (like LNG) or flash fires. For flash-fire and specialized high-heat environments, an NFPA 1991 or EN 943-2/ET certified suit (such as the AlphaTec Super or EVO line) must be selected.

What is the shelf life and maintenance schedule for an unused Type TR chemical suit?

When stored according to manufacturer parameters (in a cool, dry, dark environment away from ozone and UV radiation), the Trellchem AlphaTec Type TR has a storage service life of up to 7–10 years. An annual visual inspection and pressure decay test are mandatory under SOLAS and EN standards to maintain class-approved status.
