VRFB Dual-Chamber Electrolyte Storage Tank | Custom Rotomolding Advantage (Treering Plastics)
Specially engineered for vanadium redox flow battery (VRFB) energy storage systems, our dual-chamber electrolyte storage tank adopts
integrated one-piece rotomolding technology to deliver a seamless, high-rigidity plastic tank body with independent dual internal cavities. This
innovative dual-compartment structure physically separates positive and negative electrolytes within a single tank unit, effectively saving on-site
installation footprint and eliminating electrolyte cross-contamination risks throughout long-term operation and storage, ensuring stable and safe
VRFB system operation.
Fabricated from premium thick-walled LLDPE raw material, the tank features outstanding chemical inertness and superior corrosion resistance.
It can steadily withstand acidic electrolytes and various industrial chemical fluids commonly used in energy storage and fluid handling scenarios,
delivering excellent anti-aging performance and extending service life in harsh working environments.
Structurally optimized with external reinforcing ribs and reinforced corner designs, the tank boasts enhanced overall pressure resistance and
impact resistance. Reserved multi-specification connection ports support flexible pipeline matching and system integration. It is widely applicable
to stationary energy storage stations, industrial backup power systems, new energy renewable storage projects and other scenarios that require
standardized, secure and long-life electrolyte storage solutions.
Exclusive Custom Rotomolding Advantages of Changzhou Treering Plastics Co., Ltd.
As a professional manufacturer specializing in customized rotomolded plastic products, Treering Plastics relies on mature rotomolding processing
technology and rich industry experience to provide exclusive tailored solutions for VRFB electrolyte storage tanks, with core competitive
advantages as follows:
1. One-piece Seamless Molding, Zero Leakage Risk
Adopting advanced integral rotomolding craftsmanship, the tank body is formed in one go without any welding seams, joints or splicing gaps.
Compared with traditional spliced tanks, it completely avoids liquid leakage and structural cracking problems caused by seam aging, greatly
improving the overall tightness and structural stability of the equipment, which is critical for safe electrolyte storage.
2. High-flexibility Customization Capability
Benefiting from the low-mold-cost and high-freedom characteristics of rotomolding technology, we support full-dimensional non-standard
customization. According to customers’ on-site installation conditions and system parameters, we can freely adjust tank volume, cavity proportion,
wall thickness, port position, aperture size and external structure. Complex dual-chamber and special-shaped structural designs can be realized
efficiently, covering diversified personalized demands of different energy storage projects.
3. Reliable Material Performance & Strict Quality Control
We adopt high-purity industrial-grade LLDPE raw materials with excellent acid and alkali corrosion resistance, UV resistance and low-temperature
toughness. All raw materials and finished products undergo strict performance testing to ensure adaptability to long-term continuous operation of
VRFB systems. The thick-walled uniform molding process ensures consistent structural strength of each part of the tank, avoiding local thin walls
and pressure-bearing defects.
4. Cost-effective & Short Lead Time
With self-owned advanced rotomolding equipment and standardized production lines, we realize automated and streamlined manufacturing.
The simple mold replacement process supports rapid switching of different product specifications, greatly shortening customization and production
cycle. Meanwhile, the integrated molding process reduces auxiliary processing procedures, effectively controlling production costs and providing
high-cost-performance customized tank solutions for global customers.
5. Rich Industry Experience & Full Service Support
With years of experience in customized rotomolded products for energy storage and industrial fluid storage fields, we have served customers from
more than 20 countries and regions. We provide one-stop services including structural design, mold development, sample confirmation, mass
production and after-sales technical support, supporting OEM and ODM customized orders to meet diverse market and project requirements.
VRFB Electrolyte Storage Tank – Full English Sales Q&A Kit
Part 1: Frequently Asked Customer Questions & Standard English Reply
1. Basic Parameter Questions
Q1: What’s the actual effective volume of 43/45/75m³ tanks? Will the volume shrink?
A: Our labeled volume is the actual usable effective capacity, with no volume discount. The tank height is reserved for safe liquid level, and the
effective volume data is tested by third-party hydraulic inspection reports for your reference.
Q2: Why the standard configuration is 1 positive tank + 2 negative tanks? Can I adjust the ratio?
A: This 1:2 matching ratio follows mainstream VRFB system design standards, matching the electrolyte dosage balance of positive and negative
electrolyte loops. Custom ratios and tank combinations are available for special power station projects.
Q3: What material is the tank made of? How many years can it resist vanadium electrolyte corrosion?
A: It is integrally rotomolded with virgin food-grade LLDPE raw material, no recycled material mixed. Under normal indoor/outdoor operating
conditions, the anti-corrosion service life reaches over 10 years without contamination to vanadium electrolyte.
