How Benecor engineered a 20,000-gallon insulated tank to keep a critical chemical right where it needs to be

Engineering a Reliable 20,000-Gallon Heated Storage System for GPAM


A paper mill in North Carolina required a 20,000-gallon insulated and heated chemical storage system for glyoxalated polyacrylamide (GPAM), a temperature-sensitive, water-soluble polymer critical to paper strength and production consistency. With a specific gravity of 0.95–1.05, GPAM must be maintained within a controlled temperature range to preserve chemical integrity, pumpability, and performance throughout the production process.


Even in moderate climates, winter temperature fluctuations create significant challenges for storing temperature-sensitive chemicals. Exposure to low ambient temperatures can increase viscosity, cause phase separation, and alter chemical properties, leading to handling difficulties and inconsistent performance. In polyethylene tanks, improper thermal management can also introduce structural stress, increasing the risk of cracking, operational disruption, and safety concerns. Because GPAM directly impacts finished product quality, maintaining reliable temperature control is essential to uninterrupted mill operations.

Before engaging Benecor, an alternative solution under consideration was a refurbished tank that had previously been used for another application. While this approach may have reduced upfront cost, converting the tank for GPAM storage would have introduced additional complexity, limitations, and long-term maintenance concerns. Retrofitting heating, insulation, and controls into an existing system can create inefficiencies and operational risk, particularly for a temperature-sensitive chemical critical to product quality. The customer ultimately sought a solution that would integrate seamlessly into their process rather than require ongoing workarounds.


Benecor brings extensive experience designing and manufacturing engineered chemical storage systems for temperature-sensitive industrial applications, including polymers and caustic chemicals used throughout the paper industry. Rather than supplying a standard tank, Benecor developed a fully integrated storage solution engineered specifically for GPAM and the environmental conditions at the installation site.

The system features a 20,000-gallon high-density polyethylene storage tank selected for chemical compatibility and long-term durability. To ensure consistent chemical temperature year-round, the tank is equipped with industrial-grade heating pads, high-performance insulation, and precision temperature controls. This proven design approach is routinely used by Benecor for highly temperature-sensitive chemicals where crystallization, separation, or viscosity changes must be avoided.


Benecor’s integrated heating and control systems deliver reliable thermal regulation, reduced energy loss, and continuous operational stability. This design directly mitigates cold-weather risks such as freezing, chemical degradation, pumping challenges, and tank stress, protecting both the stored chemical and the facility itself.


By combining chemical compatibility analysis, engineered heating and insulation, intelligent temperature control, and application-specific expertise, Benecor delivers storage systems that safeguard product quality, support uninterrupted production, and provide long-term reliability. The result is a solution that ensures GPAM is stored safely, consistently, and efficiently, regardless of seasonal temperature fluctuations, helping the paper mill meet its operational and quality objectives with confidence.

These systems provide a dependable and cost-effective way to store and dispense DEF in both indoor and outdoor environments. Whether you’re managing a small fleet or scaling operations, the Lite Duty-Series offers a practical solution that balances performance with affordability. DEF presents unique challenges—especially in colder climates where it freezes at 12°F (-11°C). To address this, BENECOR offers an optional cold-weather package that helps maintain system integrity and ensures consistent operation, even in the harshest winter conditions. Compact, Island-Friendly Design Space is often limited in fueling environments. That’s why the 400- and 600-gallon Lite Duty-Series systems are designed to fit seamlessly on a standard 4-foot fueling island. This compact footprint allows fleets to integrate DEF dispensing directly into existing layouts without costly site modifications. Plug & Pump Simplicity When it comes to installation, speed and simplicity matter. BENECOR’s Plug & Pump design delivers a true turnkey solution: Position the system at your site Connect power Fill with DEF Start dispensing No complicated setup. No extended downtime. Just fast, efficient deployment that gets your operation moving. Reliable Construction, Lower Costs Durability meets value in every Lite Duty-Series system. Each unit features double-wall, high-density polyethylene (HDPE) rotationally molded construction, offering long-lasting performance and environmental protection with 110% secondary containment. Combined with proven BENECOR components, these systems are designed for easy serviceability and dependable operation—helping reduce both upfront investment and total cost of ownership. Flexible for Any Operation Every fleet has unique requirements, and the Lite Duty-Series is built to adapt. Systems are available in multiple tank capacities and can be configured to match your operational needs: AC and DC power options for facility or field installations Optional cold-weather package for freeze protection Customizable features to enhance performance and efficiency This flexibility ensures your DEF system works for you—not the other way around. Standard Features That Deliver Each Lite Duty-Series system comes equipped with a robust set of features designed for performance and ease of use: Dispenser Features: 8 GPM 120V pump Automatic stainless steel DEF nozzle 25-foot hose reel with all required hardware Integrated nozzle holder Flow meter Enclosure Features: Pre-wired and pre-piped for fast installation Hinged, lockable lid for security Double-wall construction with 110% containment Optical bund alarm Liquid level gauge Forklift accessibility (400G & 660G models) 2” stainless steel dry-break fill port Optional Enhancements To further tailor your system, the Lite Duty-Series offers additional options: Face-mounted display flow meter or in-line pulse meter Cold-weather package with 600W thermostat-controlled heat trace 12V DC pump option (for non-cold-weather units) Built to Meet Industry Standards BENECOR systems are designed with compliance and safety in mind.
