Great info on slim line tanks. Make sure you are not going for the cheapest, it will cost you on down the line!!! We have a line of tanks coming soon. 100 gal slimline and 56 gal vertical that will meet these specs and at a great competitive rate!!!
The Perfect 100-Gallon Slimline Tank: Preventing Bulging and Flexing in Pressure Washing Applications
Slimline tanks are a popular choice in the pressure washing industry, offering space-efficient storage for water and chemicals without sacrificing capacity. However, ensuring these tanks don’t bulge or flex under pressure requires careful attention to their wall thickness, structural design, and setup.
This guide provides everything you need to know about selecting and using 100-gallon slimline tanks, with an emphasis on durability and efficiency for professional pressure washing setups.
Key Dimensions of 100-Gallon Slimline Tanks
Slimline tanks are specifically designed for tight spaces, such as trailers, truck beds, or compact rigs. The typical dimensions for a 100-gallon slimline tank are:
• Length: 48 inches
• Width: 18-24 inches
• Height: 36-38 inches
These dimensions make slimline tanks ideal for pressure washing professionals who need maximum storage with minimal footprint.
Wall Thickness for Slimline Tanks
Slimline tanks must be sturdy enough to handle liquid pressure, transport stress, and chemical compatibility. Based on industry standards and feedback:
• Minimum Wall Thickness: 0.40 inches
• Suitable for general water and light chemical storage with minimal flexing or bulging.
• Optimal Wall Thickness: 0.75 inches
• Provides superior durability and strength, especially for harsh chemicals like sodium hypochlorite (SH) and for use in high-vibration environments like trailers.
Material Selection
Most slimline tanks are made from rotomolded polyethylene, a material known for its durability, lightweight nature, and chemical resistance. For specific uses:
• Water Storage: Standard HDPE (High-Density Polyethylene) is sufficient.
• Chemical Storage (e.g., SH): UV-stabilized or cross-linked polyethylene (XLPE) is necessary to resist chemical degradation and extend the tank’s lifespan.
Example Setup: A Pressure Washer’s Dream Configuration
A practical and efficient setup for pressure washing rigs includes:
1. Two 100-Gallon Slimline Water Tanks:
• Used for storing clean water to feed pressure washers.
• Positioned side by side for balanced weight distribution.
2. One 100-Gallon Slimline Tank for SH (Sodium Hypochlorite):
• Dedicated for bleach or other cleaning chemicals.
• Fitted with a chemical-resistant breather cap or vented lid to handle vapors.
How It’s Mounted:
• The three tanks are secured to a flat, reinforced base with custom brackets or frames.
• Heavy-duty ratchet straps or metal bands are used to hold the tanks firmly in place.
• A multi-tank plumbing system connects the water tanks to the pressure washer and the SH tank to a downstream injector or chemical pump.
This configuration provides a total of 300 gallons of storage while maintaining a compact footprint, ideal for professional-grade pressure washing rigs.
Preventing Bulging and Flexing
Even with sufficient wall thickness, proper mounting and handling are critical:
1. Reinforced Support:
• Use manufacturer-recommended brackets or custom-built aluminum frames to prevent flexing during transport.
2. Flat Surface Placement:
• Place tanks on a solid, flat base to avoid uneven pressure points.
3. Venting and Expansion:
• Install vented lids or breather caps to prevent pressure buildup caused by temperature changes or chemical reactions.
Regulatory Compliance
If you’re transporting chemicals like sodium hypochlorite, you must comply with DOT (Department of Transportation) regulations. A 100-gallon SH tank (weighing ~10.2 lbs per gallon) exceeds 1,000 lbs when full, requiring appropriate placards and adherence to hazardous material transport laws.
Insights from the Pressure Washing Community
Feedback from professionals in forums and Facebook groups highlights:
• Durability Matters: Thicker-walled tanks (0.75 inches) are preferred for chemical storage, ensuring long-term reliability.
• Brand Recommendations: Brands like Norwesco and Ace Roto-Mold are favored for their high-quality slimline tanks.
• Custom Builds: Many professionals create custom mounts or skids to maximize stability and prevent flexing during transport.
Conclusion
A well-designed setup with 100-gallon slimline tanks can transform your pressure washing rig into a space-efficient, high-capacity workhorse. By choosing tanks with a minimum wall thickness of 0.40 inches (optimal: 0.75 inches) and pairing them with proper mounting systems, you can prevent bulging, flexing, and other operational issues. The two water tanks and one SH tank configuration is a proven solution for professionals looking to balance capacity, durability, and functionality.
