Faster Batch Changeovers at a Pickle House with the BETE HydroWhirl® Mini

At EXAIR, a big part of what we do as Application Engineers is help customers solve practical process problems. Sometimes that means cooling a hot control cabinet with a Cabinet Cooler, moving material with compressed air with our Line Vacs, or just generally improving blow-off performance. Sometimes, it means stepping a little outside the “typical EXAIR product” conversation and pulling in the right solution from our sister company BETE.

That was exactly the case with a recent tank-cleaning application at a craft pickle-processing facility.

The Challenge: Cleaning a Small Mixing Tank Between Pickle Batches

The customer was running a small mixing tank used in the preparation of brine and seasoning blends for pickle production. Between batches, the tank needed to be cleaned thoroughly to avoid flavor carryover, ingredient buildup, and general sanitation issues. Like a lot of food processors, they were trying to balance two competing priorities. Changing over as fast as possible but still getting repeatable tank cleaning.

Their existing cleaning method was manual and inconsistent. Operators were spending too much time rinsing the tank by hand, and coverage inside the vessel wasn’t always uniform—especially around the upper walls and internal surfaces where residue could cling after mixing.

From an engineering standpoint, this is where tank washing technology makes a lot of sense. Instead of relying on a static rinse or manual wash down, a properly selected rotary tank cleaning nozzle can deliver complete, repeatable coverage while reducing labor and helping shorten cleanup time.

Why the BETE HydroWhirl Mini Was a Good Fit

In this case, the tank was relatively small, which made the BETE HydroWhirl Mini a strong fit.

The HydroWhirl Mini is a compact, fluid-driven rotary tank cleaning nozzle designed for small tanks and process equipment. In its 316L stainless steel configuration, it is built for hygienic applications and is well suited for food processing environments like this pickle operation. BETE lists it for cleaning small tanks up to roughly 6 feet in diameter, with 360° spray coverage, a self-flushing design, and PEEK slide bearings for long service life and minimal maintenance.

That combination matters in food production. When you’re washing down a tank between batches of brine, spice blends, or pickle seasoning mixtures, you want a nozzle that can do a few things well:

  • Reach the entire tank interior with consistent spray coverage.
  • Deliver enough impact to remove residue from the walls and top surfaces.
  • Hold up to repeated wash cycles without becoming a maintenance burden.
  • Use sanitary materials appropriate for food and beverage applications.

The HydroWhirl Mini checks those boxes.

How It Helped the Pickle House

For this application, the nozzle gave the customer a way to move away from manual tank rinsing and toward a more repeatable clean-in-place style process for the mixing vessel.

Because the HydroWhirl Mini is fluid-driven, it uses the cleaning liquid itself to rotate the spray head. As it rotates, it creates a vigorous 360° washing pattern that repeatedly impacts the tank interior. BETE specifically positions the HydroWhirl Mini as a solution for small tanks, drums, barrels, totes, and hygienic equipment cleaning, which made it a natural fit for a food production mixing tank.

At the pickle house, the benefits were straightforward:

1. More consistent tank coverage

2. Less manual cleaning labor.

3. Better batch-to-batch changeover

4. A sanitary material package for food applications

The stainless-version HydroWhirl Mini is made from FDA-compliant 316L stainless steel, which is important in hygienic wash-down environments. For a pickle processor dealing with acidic brines, seasonings, and frequent cleaning cycles, material compatibility and cleanability both matter.

One of the advantages of working with EXAIR is that the conversation doesn’t have to stop in compressed air. If a customer has a process challenge, our job is to help solve it even if the right answer comes from a sister company like BETE. That’s what good application engineering is supposed to look like: understanding the process, identifying the bottleneck, and matching it with a solution that makes the operation run better.

If you’re dealing with tank cleaning challenges in food processing, chemical mixing, tote washing, or other small-vessel applications, the HydroWhirl Mini is worth a look.

Precision Coverage in Tight Spaces: The EXAIR PowerStream Nozzle

In industrial manufacturing, bigger isn’t always better… especially when you’re dealing with precise liquid application in cramped quarters. EXAIR’PowerStream Liquid Atomizing Nozzles are designed to solve the common headache of achieving uniform liquid distribution without the need for bulky equipment or a compressed air source.

What Makes PowerStream Nozzles Different?

Unlike standard nozzles that might produce a messy, uneven spray, the PowerStream uses a “liquid-only” design. It operates simply by forcing pressurized liquid against a precision-tuned, angled surface. This creates a deflected flat fan pattern at a 75° angle from the nozzle orientation, essentially forming a “water curtain” or sheet of liquid.

Key Performance Benefits

  • Clog-Resistant Design: Perfect for environments where you might be spraying slightly viscous fluids or liquids containing small particulates.
  • No Compressed Air Needed: Because it relies solely on liquid pressure (up to 250 PSI), it’s an energy-efficient alternative for applications where compressed air is unavailable or unnecessary.
  • Rugged Construction: Built from Type 303 stainless steel, these nozzles are ready for harsh, corrosive environments and can withstand temperatures up to 800°F (426°C).
  • Compact 1/8 NPT Footprint: As EXAIR’s smallest liquid-only nozzle, it fits into tight spots where other spray solutions simply can’t reach.

Ideal Applications

The PowerStream Nozzle is a versatile workhorse for general-purpose industrial tasks, including:

  • Cleaning & Rinsing: Washing vegetables, rinsing conveyor belts, or applying detergents.
  • Cooling & Quenching: Spraying water or light oils onto hot parts during production.
  • Dust Suppression: Creating a fine curtain of liquid to capture airborne particles.
  • Coating: Applying even layers of rust inhibitors, lubricants, or dyes.

Axial vs. Deflector: Which BETE Fan Nozzle Really Makes the Cut?

Since BETE became part of the EXAIR family back in 2024, we’ve been able to offer a much deeper bench of spray technology to solve the more complex fluid delivery problems our customers face. When you need precision in a spray process, choosing the right pattern is just as critical as the fluid you’re pumping. Fan nozzles are the go-to when you need a flat sheet of liquid with a specific impact. Whether you’re washing down a conveyor or applying a thin coating to a part, the goal is uniform distribution and, often, high force.

There are two primary ways these fan patterns are created: axial and deflector. With an axial fan nozzle, the liquid exits through an orifice and naturally widens into a flat spray. These are great for general cleaning and washing because they provide a tapered edge. This is perfect for overlapping multiple nozzles on a header to get seamless, uniform coverage across a wide area without any “light” spots between nozzles.

Then you have deflector-style nozzles. In this design, the fluid hits an external surface after exiting the orifice, which “peels” the liquid into an extra-wide fan. Because the fluid is deflected, these nozzles can achieve a much higher impact at lower flow rates, making them ideal for heavy-duty scrubbing, rinsing, or suppressing dust.

We see these used across a ton of different industries because of that versatility. In food and beverage, they’re a staple for bottle and container washing. In the steel industry, you’ll find them cooling down rolls or applying lubricants. They even play a huge role in fire protection, specifically in deluge systems where you need to move a lot of water quickly and accurately.

The main takeaway is that fan nozzles are the best choice whenever you have relative motion between the nozzle and the target. If you have a product moving down a line that needs to be wetted, coated, or cleaned, a fan pattern is likely the most efficient way to get it done.

Between EXAIR’s compressed air expertise and BETE’s industrial spray nozzle catalog, we can help you spec out the right nozzle for the job. Give us a call and we’ll walk through the flow rates and spray angles your application requires.

HollowStream Spray Nozzles

At EXAIR we are known for our intelligent compressed air products. We’ve written many blogs on the benefits of our quiet and efficient compressed air products. We also have a handful of products that don’t use compressed air. Our  HollowStream™ Cone Liquid Nozzles are one such product.

As the name would suggest, the HollowStream™ Cone Liquid Nozzles produce a hollow cone of liquid, creating a ring around the target. This will reduce the liquid usage as compared to the OmniStream™ Cone Liquid Nozzles.  They are available in NPT female threads in 1/8″, 1/4″, 3/8″, and 1/2″ sizes with a variety of liquid flow rates.

When fluid is supplied into the body, a swirling action is created within the vortex chamber. This vortex is what creates the cone pattern. Then the precision orifice of the nozzle breaks this surface tension of the liquid, exiting the nozzle with the hollow ring pattern. Compared to our Air Atomizing Spray Nozzles, these nozzles generate more liquid volume and produce a coarser spray pattern. They can achieve flow rates ranging from 0.06 GPM and up to 14.00 GPM.

They are all made of 303 stainless steel with a vaneless design to help resist clogging, making them a great option for slurries, or liquids containing particulate. They can handle 250 PSIG of liquid pressure and operate at temperatures up to 800°F. And due to the fact that they only require pressurized liquid, and not an additional source of compressed air, they are easy to plumb, and are suited for applications where there may be space constraints.

Some common applications include cooling, cleaning, washing, rinsing and dust suppression. As long as you know the spray pattern you are looking to achieve, or the flow rate you want to maintain, our performance tables in our catalog and website make it easy to make your selection.
