What’s the best way to ventilate a potato storage building?

That depends on your storage type (bulk or box), your climate, and your potato variety. We design ducted systems or integrate air floors based on what will move air evenly, minimize hot spots, and support the humidity and temperature levels you need.

What kind of climate control systems are needed for storing potatoes?

Most modern storage facilities include integrated airflow, humidity control, and refrigeration. We work with your mechanical team—or bring in ours—to ensure these systems are designed into the building layout from the start, not tacked on after.

Can you retrofit my existing potato storage building?

Yes. If the structure is sound, we can upgrade insulation, airflow, fan systems, and refrigeration-ready components. A retrofit can extend the life of your building by 20+ years—at a fraction of the cost of new construction.

Do I need separate zones for different potato varieties?

In many cases, yes. Different varieties have different ideal temperatures and humidity ranges. We can design zoned storage within one building so you can store multiple varieties with minimal shrink and better control.

Do you build bulk or box potato storage?

We do both. Each method has pros and cons, and we’ll help you choose based on your handling equipment, storage goals, and how fast the product needs to turn.

How much does it cost to build a potato storage facility?

Every farm is different—and so is every budget. We don’t push pre-fabricated designs or unnecessary features. Instead, we focus on value engineering: designing around your potato storage goals, mechanical systems, and site conditions to get you the best performance for the money you plan to spend. Our goal is to help you make smart decisions early so you can avoid expensive fixes later.

Onion Storage Buildings Built for airflow, climate, and crop quality

A quality onion storage building doesn’t just hold product—it protects it. From harvest through shipping, our buildings maintain the airflow and moisture control onions need to stay firm, dry, and market-ready.

Our Process

Purpose-Built for Onion Storage

Understand your harvest

Every storage design starts with your production volume, turnover rate, and handling method—bulk or bins, short-term hold or long-term storage.

Design for your variety and region

From sweet to storage onions, each variety has different airflow, humidity, and temperature needs. We build to match your crop and local climate.

Plan systems early

We don’t leave ventilation, insulation, or curing conditions to chance. Airflow, cooling, and moisture management are part of the initial design—not afterthoughts.

Our Approach

What Makes a Good Onion Storage Building Design?

A great onion storage facility starts with understanding how onions behave after harvest. From airflow direction to bin spacing and structural clearances, every part of the building is engineered and built to support crop quality, crew efficiency, and climate control from the ground up.

Smart Systems for Onion Storage

From first cure to final load-out, onion storage requires balance. We work with you to engineer every system to support a stable environment and prevent costly losses.

Directional airflow that reaches every bin

Whether you're storing in bins or bulk, we calculate airflow velocity, duct placement, and spacing to ensure consistent movement and avoid hot spots or pressure loss.

Humidity control without excess moisture

High humidity prevents shrinkage, but too much causes rot. We design insulation and vapor barriers that stabilize relative humidity and protect your crop in any climate.

Flexible zones for curing and holding

Need a fast cure or long-term storage—or both? We can build zones into your facility that maintain airflow and temp control without overcomplicating operations.

Built-in refrigeration readiness

If active cooling is part of your setup, we account for that early—designing the structure to support mechanical loads and maintain clearances from the start.

Smarter access and equipment flow

Bin access, stack height, forklift lanes—these aren’t afterthoughts. We design around your real-world equipment needs so product can move in and out without friction.

Built for Seasonal Swings

Onion storage buildings face hot harvest days and cold winter nights. We engineer roof pitch, ventilation openings, and wall systems to handle wide temperature swings without compromising interior stability.
