Single Skin AdBlue Tanks — Cost-Effective DEF Storage

Single-skin polyethylene AdBlue tanks provide reliable, affordable DEF storage for sites that already have compliant secondary containment in place. Where an existing bunded compound, spill tray or containment area satisfies environmental regulations, a single-skin tank is the most cost-effective way to store AdBlue (AUS32) — without compromising on material compatibility or DEF purity.

Overview

What Are Single Skin AdBlue Tanks?

Single-skin AdBlue tanks are single-wall polyethylene vessels designed to store Diesel Exhaust Fluid (DEF / AUS32) within an existing compliant containment area. Unlike self-bunded (double-skin) tanks, they do not incorporate their own secondary containment — which is why they must be installed inside a bunded compound, spill pallet or other approved containment structure that meets the 110% secondary containment requirement under AS 1940 and local EPA guidelines.

The key advantage of single-skin tanks is lower purchase cost — you're not paying for a built-in bund if your site already provides one. Polyethylene construction remains essential regardless of tank type: DEF is chemically aggressive toward most metals, and only poly, stainless steel (316L) or similarly inert materials should contact AdBlue. Single-skin poly tanks maintain DEF purity to ISO 22241 standards and are ideally suited to smaller operations, secondary storage points or farms where bunding already exists.

Key Features

Polyethylene construction — chemically compatible with AUS32 / DEF; prevents contamination of SCR systems
More affordable than self-bunded options — ideal where compliant site bunding already exists
Maintains ISO 22241 DEF purity — no metal ion leaching that degrades AdBlue quality
Suitable for bunded compounds and spill trays — works within existing containment infrastructure
Compact sizes for smaller volumes — practical for farms, small depots and secondary dispensing points
Compatible with AdBlue-safe pump systems — easily paired with diaphragm or electric pumps

Compact poly tanks for farms, small fleets and secondary dispensing locations with existing spill containment. Lower entry cost for sites with modest DEF requirements.

Bunded Compound

Mid-Volume Single Skin AdBlue Tanks

For operations within a compliant bunded area needing regular DEF top-up without the cost of a self-bunded vessel. Sized for regular fleet servicing cycles.

Portable

Single Skin AdBlue Tanks with Stand

Elevated single-skin poly tank on a stand for gravity-assisted or pumped dispensing. Positioned within a bund tray or existing containment compound.

Pump Package

Single Skin AdBlue Tank & Pump Combos

Bundled single-skin tank and AdBlue-safe electric or diaphragm pump kits for sites that have their own containment but need a complete dispensing solution.

Selector Guide

Single Skin vs Self Bunded AdBlue Tanks

Application	Recommended Product	Key Consideration
Existing bunded compound	Single-skin AdBlue tank	Most cost-effective — containment already provided
No existing bunding on site	Self-bunded AdBlue tank	Integral 110% containment — no civil works needed
Small farm or single vehicle	Small single-skin poly tank	Compact; fits within spill tray on a bunded pallet
Secondary dispensing point	Single-skin tank with pump combo	Cost-effective addition to a compliant bunded area
Gravity dispensing setup	Single-skin tank on stand	Elevated installation within existing containment

Key Benefits

Why Choose a Single Skin AdBlue Tank?

Advantages for Bunded Sites

Lower purchase price — no integrated bund means reduced cost where site containment already exists
Preserves DEF purity — poly walls prevent metal contamination that damages diesel particulate filters and SCR catalysts
Lighter and more manoeuvrable — single-skin poly tanks are easier to reposition within a bunded area
Scalable secondary storage — add a tank within an existing bunded compound without major infrastructure investment
Compatible with Fuelgear pump kits — pair with AdBlue-safe diaphragm or electric pumps for a complete dispensing solution
Appropriate for low-to-medium volume operations — right-sized storage for farms, small fleets and workshop compounds
