JOA Air Solutions

Save on Energy Costs with Energy Recovery Scrubbers

Rising costs for energy and gas are eating into your profits. That makes it more critical than ever to maintain an efficient operation in your facility. Simultaneously, you want to keep emissions under control. Because not only are we dealing with an energy crisis, we are also facing ever more stringent emission legislation. Fortunately, energy saving, cost saving, sustainability, and regulation compliance can go hand in hand. An Energy Recovery Scrubber effectively cleans your exhaust streams, which lowers unwanted emissions into the environment. Additionally, the scrubbing process extracts heat from the same exhaust stream, which can be reused in your facility.

For a large manufacturer in the FMCG industry, our Scrubbers helped reduce energy consumption by 900 kW, leading to savings of 5.9 GWh annually

Why choose an Energy Recovery Scrubber from JOA Air Solutions?

There are many suppliers of standardized scrubbers and heat recovery solutions, like heat exchangers. But a solution that combines the two is rare. And there are many more reasons why you’d want to implement JOA’s Energy Recovery Scrubbers:
 

• We use unique air technical modeling to create the most efficient solution for your situation
• Our solution enables you to recover low-grade waste heat.
• You’ll be able to clean emissions, while also connecting heat providers to energy consumers
• Up to 99,9% efficiency for our Inline Venturi Scrubbers (at 10 micron or higher)
• The self-cleaning Inline Venturi beds remove dust efficiently
• High maintenance condensers can be replaced (no fouling & freezing risk)
• The solution requires little energy and consumables
• Option to add a second stage odor removal

Don’t give harmful vapors & fumes a chance

Air Pollution, Handling Volatile Organic Compounds (VOC’s) and ineffective vapor & fume extraction leads to unhealthy and unsafe environments. Coalescer Belt Filters are able to give back control over your process by removing aerosols so Activated Carbon or Dust filters remain effective. Also, the lead to reduced downtime, and minimized risks for operators. This results in consistent emission control and Healthy, Safe industrial work conditions.

Stop guessing, start expecting by trusting on JOA Air Solutions

We do not provide standard solutions. We truly would like to understand your specific requirements before coming up with the right answers.

Every good performing extraction system starts with a well-designed extraction hood. Effective hood design can make all the difference between a mediocre, a good and an excellent extraction system. JOA extraction systems are able to reach up to a 95% extraction efficiency.

There are as many hood designs as there are applications. A hood can be outfitted with slots to prevent over-extraction of air and to make the system more energy efficient. Every part of the hood is shaped to optimally accommodate air into the system.

In many situations, a simple extraction system will suffice, but in others a push-pull system is advisory. In a push-pull system, air is not only extracted, but a current of clean air is used to push the polluted air towards the extraction hood. This ensures a more precise and efficient method of extraction. In addition, the current of fresh air is beneficial to operator health and safety.

The piping needs to meet the same strenuous requirements as the hood. Every bend and curve is designed to maintain an optimal air current between hood and collection. On a brand new system, JOA favors the use of piping without valves. Any element that can disturb the airflow, like valves, can cause a buildup of particles within the system. This buildup can, depending on the type of particle extracted, cause anything between maintenance downtime and serious explosion risk.

Optimizing Hoods with advanced Computational Fluid Dynamics

CFD-optimized extraction systems and deflector hoods are designed to minimize the extraction of valuable dust. This also reduces the risk with explosive dust in the ATEX zone and reduces the downtime of the facility due to lesser need for cleaning or filter replacement.

The JOA Deflector Hood™ in combination with our GCM™ Air Technical Modeling software guarantees an atmospheric (pressure less, -1Pa) extraction on sensitive process equipment, such as feeding equipment. This means the following:

• Product Recovery: Product particles are mainly recaptured back in the process, having only a minor amount of dust ending up in the filter.
• Reduces Risk of Pressure Build-up: The risk for pressure build-up or backflow during feeding processes are eliminated due to balanced (atmospheric) venting. This prevents influences at the weighing and feeding.

Applying the JOA Deflector in combination with a balanced extraction system, including Balancing Restrictors can lead to:

• Less decline of product, rejected batches and improved product quality.
• Eliminating cross contamination
• Precise dosing / feeding made possible
• Reduced dust emissions at the emission source
• Reduced material / powder waste (40-70%)
• Less maintenance required
• Guaranteed ‘Maximum Allowable Concentration’ (MAC) resulting in operator protection ( e.g. g.< 1mg/)
