Today we shipped a 2,000-gallon customized coffee filter tank to a commercial coffee producer in the United States. For the customer, it's the centerpiece of a new cold brew production line. For our team, it's the result of several months of process discussions, fabrication, and pre-shipment testing.
This post walks through what the project involved, why a tank this size makes sense for a scaling cold brew operation, and the manufacturing details that matter when you're buying large stainless steel processing equipment from overseas.
The U.S. cold brew market has grown fast, and producers who started with small-batch systems are now running into a familiar ceiling: they're brewing more batches per week than their equipment was designed to handle.
That was the situation here. The customer had outgrown their existing setup and needed a single large-capacity filter tank that could handle bigger batches without adding labor for repeated small runs. After reviewing their production flow, target output, and facility layout, we specified a 2,000-gallon stainless steel coffee filter tank built for efficient filtration and stable, repeatable batch performance.
The practical benefit for a producer at this stage is straightforward. Larger batch volume means fewer handling cycles, tighter batch-to-batch consistency, and more predictable production planning—the things that matter when you're supplying retail or wholesale channels on a schedule.
Cold brew is made by steeping coffee in cold or room-temperature water over an extended period, rather than using heat. The slow, low-temperature extraction produces a smoother, sweeter cup with noticeably lower acidity than hot-brewed coffee.
The trade-off is that cold brew is unforgiving of inconsistent equipment. Because extraction happens slowly over many hours, small variations in coffee-to-water ratio, steep time, or filtration efficiency show up clearly in the final product. That's why the tank design—not just its capacity—directly affects product quality.
A commercial cold brew filter tank needs to deliver on several fronts at once:
Consistent, controlled extraction across the full batch volume
Efficient filtration that separates grounds cleanly without over-extraction
Sanitary construction that supports fast, thorough cleaning between batches
Repeatable performance so batch #100 tastes like batch #1
The tank we shipped was designed around exactly these requirements.
A coffee tank is a production component, not a storage barrel—so we treat fabrication accordingly. For this project, our team focused on the details that determine whether a tank performs reliably over years of daily use.
Manufacturing Focus | Why It Matters |
Food-grade stainless steel (304) | Corrosion resistance and hygienic, food-safe contact surfaces |
Welding quality | Sanitary welds prevent bacterial harborage and product contamination |
Internal surface polishing | Smooth interior surfaces enable effective CIP cleaning |
Filter tank configuration | Efficient grounds separation without channeling or over-extraction |
Fittings and connections | Reliable integration into the customer's existing line |
Pre-shipment inspection | Catches structural and finish issues before the tank leaves the factory |
Before packing, the completed tank went through a full inspection covering workmanship, structural integrity, surface finish, and fitting alignment. The goal is simple: minimize surprises during installation and start-up on the customer's side, thousands of miles away.
Shipping a tank this size overseas carries real risk if it isn't handled properly. Large stainless steel vessels can be damaged in transit through poor loading, inadequate surface protection, or shifting during transport—and repairs after arrival are expensive and slow.
Our shipment process for this project covered:
Final equipment inspection before packing
Surface protection to guard against scratches and transit damage
Secure packing suited to the tank's size and weight
Careful loading preparation for stable transport
Export documentation and shipment coordination
The tank departed for the United States on July 20, 2026, packed and secured for the journey to the customer's facility.
This filter tank is one component within Cassman's broader Cold Coffee Brew System, engineered for professional cold brew production.
The system is built around low-temperature, slow extraction and lets producers control the variables that define cold brew quality—temperature, steep time, coffee-to-water ratio, and filtration. It can be customized by production capacity, tank configuration, filtration method, and cooling setup to match a specific operation.
Key advantages for commercial producers:
Low-temperature extraction design for reduced bitterness and acidity
Programmable extraction process for repeatable results
Flexible coffee-to-water ratio control
Optimized filtration structure
Food-grade stainless steel construction throughout

What is a 2,000-gallon coffee filter tank used for?
It's used for large-scale commercial coffee processing—particularly cold brew—where high batch volume and efficient filtration are required. At this capacity, producers can handle bigger batches with fewer handling cycles and more consistent output.
Can Cassman customize coffee filter tanks?
Yes. We customize by capacity, tank structure, filtration configuration, fittings, surface finish, and process requirements. Each tank is specified around the customer's production flow rather than sold as a fixed off-the-shelf unit.
Is this tank suitable for cold brew coffee production?
Yes. Stainless steel filter tanks are well suited to cold brew and integrate into a complete cold brew processing line. Their sanitary construction and controlled filtration support the slow extraction that cold brew requires.
Does Cassman supply coffee equipment to the United States?
Yes. We have delivered stainless steel beverage and coffee processing equipment to customers internationally, including projects in the United States, with export packing and shipment support handled in-house.
What are the advantages of stainless steel coffee tanks?
Food-grade stainless steel offers hygienic operation, corrosion resistance, easy cleaning, and a long service life—making it the standard material for commercial coffee and beverage production.
