TKC-20HQ Modular Special Container — Dual-Certification Driven Integrated Safety Storage Solution for High-Risk Environments

  • Product Overview

TKC-20HQ is a modular special container designed specifically for the safe storage of hazardous chemicals and high-risk materials. Its core value lies in having obtained dual authoritative certifications, enabling effective response to comprehensive hazardous materials safety challenges in harsh environments:

Modular design: Uses a standard 20-foot container structure, facilitating sea and land transport and handling, enabling rapid deployment and easy relocation.

Dual authoritative certifications:

  1. FM6049 chemical storage certification — meets FM’s stringent requirements for fire safety and chemical storage integrity, focusing on addressing the inherent risks of the stored materials such as flammability, reactivity, and leakage.

  2. ExdbebIICT6Gb explosion-proof certificate — the overall unit and electrical systems are suitable for Zone Zone explosive hazardous areas, with the highest gas group IIC and temperature class T6. This certification focuses on preventing ignition in explosive hazardous environments.

  • Core Interpretation of the Dual Certifications
  1. FM6049 fire protection and leak containment Fire resistance and thermal insulation: FM certification implies the product must have a certain degree of fire resistance. The container structure is designed to resist external fires or limit the spread of internal fires, and is equipped with firewalls.

Leak control and containment: Equipped with a liquid collection sump (also called leak-proof tray/containment sump), effectively collecting accidentally leaked liquids, preventing their spread to the external environment, and reducing the risk of fire propagation.

Pressure relief/venting: Equipped with explosion relief panels (also called pressure relief panels), which, in the event of internal deflagration, guide the blast wave and pressure toward a safe direction through predetermined weak areas, reducing damage to the container’s main structure.

Structural robustness: Meets FM requirements for storage unit structural strength, able to withstand routine operations and potential external impacts in industrial environments, ensuring safety and reliability during service.

  1. ExdbebIICT6Gb electrical isolation for explosive areas Flameproof enclosure (dbFlameproofEnclosure): Components that could ignite an explosive atmosphere (such as switches, motors, internal contacts of sockets) are placed in a specially designed robust enclosure that can withstand internal explosion pressure and prevent flame propagation to the outside.

Increased safety (ebIncreasedSafety): Additional safety measures are applied to terminal blocks, cable entries and certain types of luminaires to prevent the generation of arcs, sparks or dangerously high temperatures during normal operation and anticipated fault conditions. TKC-20HQ adopts an Exdbeb composite explosion protection type, combining the advantages of both protection methods.

IIC gas group (GasGroup): Suitable for the most hazardous gas group, including very easily ignitable gases such as acetylene and hydrogen, and can be safely used in almost all industrial gas or vapor environments.

T6 temperature class (TemperatureClass): The maximum temperature of any equipment surface will not exceed 85°C, ensuring it will not ignite surrounding explosive gases with autoignition temperatures above 85°C, providing the highest level of thermal safety assurance.

  • Gb Protection Level (Equipment Protection Level): Has a high protection level, suitable for Zone

areas (areas where explosive gas atmospheres may occur during normal operation), and is of course also suitable for the lower-hazard Zone2 area. Achieving this level requires safety even under anticipated fault conditions.

  • Core Characteristics
  1. Fully protected electrical system: Built-in ExdbebIICT6Gb-grade explosion-proof lighting, explosion-proof sockets, and explosion-proof fans ensure that no additional explosion-proof equipment is required inside hazardous areas; the entire system’s safety is guaranteed to prevent ignition accidents caused by internal equipment operation.

  2. Intelligent interlock optional: Optional combustible gas online detection module and Ex-rated ventilation fan, interlocking with the cabinet’s internal exhaust system to automatically increase ventilation and exhaust when vapor concentration approaches the lower explosive limit, and enabling remote alarm and integrated management via on-site DCS/SCADA. May also be equipped with temperature control detection systems.

  3. Rapid deployment: Equipped with container lifting interfaces and bottom casters, can be set up at construction sites or incident scenes within hours and is easy to relocate.

  4. Modular expansion: The standard 20-foot container structure supports stacking and parallel multi-container use, enabling quantity or multi-category chemical zoned management.

  • Rich Application Scenarios
  1. Laboratories and R&D centers (Zone2) Materials: Organic solvents, analytical reagents and other small-to-medium quantity chemicals.

Risks: Solvent vapor accumulation forming Zone atmospheres, fire, leaks, and sparks from internal electrical equipment potentially causing ignition.

Solution: FM6049-standard storage space ensures safe storage and leak containment (liquid collection sump, explosion relief panels); ExdbebIICT6Gb-grade explosion-proof lighting/sockets/fans completely eliminate ignition sources, permitting direct use of small instruments inside the cabinet (such as stirrers, pumps, etc.).

  1. Petrochemical and gas facilities (Zone1/2) Materials: Solvents, cleaners, additives, gas cylinders (including H2), related chemical agents.
  • Risks: High probability of flammable gases/vapors (Zone 1/2), small-scale deflagrations, accidental cylinder failures, storage container leakage risks, fire hazards.

  • Solution: ExdbebIICT6Gb comprehensive explosion protection suitable for Zone areas; FM6049 firewalls and explosion relief panels effectively mitigate accidental fires or small-scale deflagration impacts, and the robust structure combined with Ex explosion-proof characteristics make it suitable for safely storing high-pressure gas cylinders. Optional combustible gas online monitoring and interlocked exhaust can be installed.

  1. Coating and surface treatment workshops Materials: Paints, thinners, fluxes, cleaners (VOCs) and other flammable liquids.

Risks: High VOC vapor concentrations, static or electrical sparks causing ignition, highly flammable materials, need for effective segregation and ventilation management for different chemicals.

Solution: FM6049 leak containment (liquid collection sump); Ex-rated ventilation fans (external explosion-proof fans) and lighting continuously control internal cabinet gas concentrations within safe ranges; explosion relief panels promptly vent during sharp pressure fluctuations; "cabinet-in-cabinet" fire zoning arrangements can be implemented to reduce operator entry into high-risk areas.

  1. Energy and battery maintenance areas (Zone2)
  • Materials: Lead-acid / lithium battery modules, ≤20kWh small ESS battery packs, related charging equipment.
  • Risks: Hydrogen evolution during charging (H2) explosion (Zone 2, IIC gas group), thermal runaway, electrolyte leakage.
  • Solution: ExdbebIICT6Gb-grade explosion-proof sockets and cabinet-top temperature control detection for real-time monitoring of gas concentration and temperature, automatically cutting power and triggering exhaust to ensure charging safety; FM6049 liquid collection sump effectively manages electrolyte leaks, while pressure relief design and robust Ex-grade enclosure jointly address early thermal runaway risks.
  1. Construction sites and emergency deployments Materials: Paints, additives, fuel, extinguishing agents, emergency wash agents, spill response materials.

Risks: Temporary environment compliance difficulties, potential flammable vapors, electrical safety, need for rapid deployment.

  • Solution: Modular container equipped with lifting interfaces and bottom casters for rapid handling; Ex explosion-proof sockets, lighting and explosion relief panels ensure temporary on-site power and fire safety; integrated FM and Ex certifications eliminate the need for secondary modifications.
