RomoTech 550 Gallon Polyethylene Storage Tank

The RomoTech 550 Gallon storage tank is designed for heavy-duty outdoor and industrial use. Its UV-stabilized polyethylene construction resists cracking and warping, making it suitable for long-term chemical and liquid storage. The rustproof, BPA-free design helps prevent leaching and corrosion, supporting safe handling for potable water and non-flammable chemical liquids. Ideal for farms, factories, or large-scale operations where durable, high-capacity containment is essential. This dome-top tank balances volume with stability and ease of maintenance.
Application notes: Use for agricultural solutions, potable water reserves, or non-flammable industrial liquids. Consider mounting or leg supports if ground flexibility is a constraint. Ensure proper venting and dosing access for added safety in chemical handling.
RomoTech 60 Gallon Storage Tank with Legs

RomoTech’s 60-gallon tank provides a compact solution suited for smaller spaces or pilot storage options. The heavy-duty polyethylene build is UV-stabilized to resist outdoor degradation, and the dome-top design remains rustproof and BPA-free for safe liquid containment. Its size makes it practical for on-site chemical work, irrigation solutions, or emergency reserves where mobility and quick access are priorities. A sturdy legged setup ensures stable placement on varied surfaces.
Practical considerations: Ideal for smaller facilities or temporary storage needs. Evaluate transport requirements and the availability of compatible lids or fittings for hoses and pumps when integrating into existing systems.
AFWFilters Polyethylene 15 Gallon Chemical & Solution Tank

The 15-gallon AFWFilters tank is a compact option with clear measurement markers (5, 10, 15 gallons) and a large 3.75-inch opening. This design facilitates easy mixing, sampling, or direct pouring of chemical solutions. It is appropriate for laboratory setups, small-scale processing, or storage of concentrated solutions. The plastic construction reduces risk of shattering, and the integrated markings help with precise dosing and monitoring of volumes during use.
Use considerations: Suitable for non-flammable chemicals and liquid solutions. Ensure compatibility of stored chemicals with polyethylene to prevent reaction with tank material and to maintain tank longevity.
AFWFilters Polyethylene 35 Gallon Tank

The 35-gallon polyethylene tank offers an 18-inch diameter and is 32 inches tall, with a lid that unscrews from the top. This configuration supports easy access for cleaning, filling, or adding tubing. The design is compatible with chemical storage requirements where a larger opening improves handling. It is well-suited for moderate-volume chemical solutions and routine maintenance tasks in facilities that require quick access to liquid contents.
Key considerations: Ensure appropriate ventilation and secure lid closure during storage of volatile substances. Plan for tubing insertions and pump connections to avoid leaks and maintain containment integrity.
RomoTech 125 Gallon Storage Tank with Legs

The RomoTech 125-gallon storage tank offers robust capacity for industrial or agricultural liquid storage. Built from UV-stabilized polyethylene, it resists outdoor exposure and maintains form under varying environmental conditions. Like other RomoTech models in this set, it is rustproof and BPA-free, supporting safer long-term storage for a range of liquids including agricultural solutions and non-flammable industrial chemicals. The legs provide stability for placement on uneven ground or surfaces that require elevated support.
Operational guidance: Select for medium to high-volume storage needs. Confirm compatibility with your chemical profiles and ensure fittings or adapters are suitable for your pumping or dosing setup.
Buying Guide: Key Purchase Considerations
- Material and safety: Look for UV-stabilized polyethylene for outdoor resilience and BPA-free formulations to minimize leaching risks. Confirm compatibility with the stored chemicals to prevent reactions.
- Capacity and footprint: Match tank size to your daily throughput and available space. Consider whether a tank with legs is preferable for level positioning or ground clearance.
- Lid design and access: Tanks with secure lids and accessible openings simplify filling, cleaning, and sampling. Larger openings enable faster handling of viscous or particulate-containing liquids.
- Durability and weather exposure: UV resistance helps prevent plastic degradation in sunlit environments. Rustproof features reduce corrosion risk for metal-related equipment and fittings.
- Fittings and customization: Check for compatible hose connections, pump inlets, and venting options. Some tanks allow easy customizations for tubing, sampling ports, or mixers.
- Regulatory and safety considerations: Ensure compliance with local regulations related to chemical storage, spill containment, and worker safety. Use secondary containment where required.
- Maintenance and cleaning: Choose tanks with smooth interiors and accessible openings to ease cleaning and reduce contamination risk. Plan for routine inspection of seals and lids.
- Mobility vs. permanence: Smaller, lighter tanks offer flexibility, while larger tanks favor stationary, high-volume storage. Consider anchoring or platform mounting for stability.
- Cost of ownership: Evaluate initial cost alongside expected lifespan, maintenance, and potential downtime due to cleaning or inspections.
These selections provide options across capacities and use cases, emphasizing durability, chemical compatibility, and practical access. For larger operations or specialized chemicals, consult with a storage professional to ensure the chosen tank meets your exact safety and handling requirements.
