VortX EcoFilter

Green Afterburner Alternative

Coffee roasting is a dirty business, so using an afterburner to handle your pollutant control with either be a necessity (per some local emission laws) or a responsible neighborly gesture. There are plenty of good traditional afterburners to select from, but if sustainability is a core value, you might be looking for more clean and eco-friendly options. That's why we offer you the option of the VortX ExoFilter.

What Sets VortX EcoFilter Apart

The revolutionary VortX EcoFilter is the coffee roasting industry's first hydro-powered emission reduction system. Yes, you read it right, it harnesses the power of water! By utilizing a cyclone's energy and atomized water, the VortX EcoFilter efficiently eliminates chaff, dust, smoke, and odors from the waste stream. With the VortX EcoFilter, exhaust removal reaches an impressive 80%, making it the ultimate energy-friendly and highly effective filtering solution for tackling smoke and odors. Your neighbors will appreciate the difference it makes. Say goodbye to unwanted emissions and hello to a more environmentally conscious coffee roasting experience.

What Customers Say

"At CO-RO one of our core values is sustainability, and using a traditional afterburner really undermines that core value. The VortX uses water vapor and the only energy the VortX needs is the energy to run the water pump. If you care about the environment you have to look at a better technology and we're really proud to be one of the first installations of the VortX." — Floy A., Bay Area CoRoasters

"We are part of a public market, a major retail center in Oxnard, CA. We didn’t want our smoke and odor going into the neighborhood and negatively impacting people’s lives. We want to produce the cleanest air we can using the best method we can, so we are using the VortX to handle the cleaning of our air. It’s awesome because there is minimal cleaning, and it’s a much better option for our business." — Shawn P.

Is the EcoFilter simply a wet scrubber? NO

VortX engineers took the basic concept of a wet scrubber and reinvented it specifically for coffee roasting. Traditional wet scrubbers interfere with airflow during roasting; the EcoFilter improves airflow and the entire roasting process.

What is the key difference between the VortX EcoFilter and an afterburner? GREENHOUSE GAS

Afterburners incinerate smoke and odor at extremely high temperatures requiring consumption of up to 5 times the natural gas used by the roaster itself. The EcoFilter captures smoke and odor by instantly cooling the exhaust air to condense out the contaminants and capture them in water and strip them from the exhaust air using the centripetal force of a cyclone.

What is the environmental cost of an afterburner vs. an EcoFilter? CLIMATE CHANGE

Does VortX make an EcoFilter which will fit my roaster? YES

Tell us the volume of air you need filtered and we will advise which model EcoFilter will fit that need. Our current models can work for roasters up to 1200 CFM total airflow.

Does an EcoFilter require a conventional chaff cyclone? NO

An EcoFilter can safely filter all the chaff and dust from your roaster far more efficiently than a conventional cyclone or internal chaff collector. The wet chaff is easily compacted or bricked and can be used as a nutrient rich soil amendment.

Will installing an EcoFilter interfere with my roaster or require changes to my roast profiles? NO

The static pressure inside the EcoFilter is similar to other high efficiency cyclones. The duct design included with your purchase considers the fans in your roaster and the route the air must take to exit your roastery; it will include everything you need to assure ideal air flow. The cyclone and exhaust stack remain clean and therefore will not inhibit airflow over the course of many roasts.

How difficult is the installation of the EcoFilter? EASY

We design the ducting for you and provide a complete Bill of Materials so you may obtain multiple bids. We can also assist in obtaining bids. The use of clamp-together, positive-pressure ducting further simplifies the installation.

What can I expect to see and smell at the end of my exhaust stack? WATER VAPOR +

Every installation is unique and is subject to many factors not controlled by the EcoFilter. In general, what comes out the end of the stack are:

  • White water vapor which will pick up color as the roast progresses into 2nd crack; we have videos demonstrating this.
  • The VortX process captures the majority of the VOCs which create the harsh and acrid odor; the remaining odor is mild and reminiscent of baked coffee/bread.
Can using the EcoFilter actually cost less than doing nothing? YES

Exhausting untreated smoke and odor increases local air pollution and risks offending your neighbors, leading to complaints and fines. Doing nothing also increases your risk of fire in your chaff collector and exhaust stack and reduces air flow during roasting unless you clean the airways. The costs of duct cleaning alone can pay for a VortX in just a few years. The peace of mind that comes from knowing you are not offending neighbors and also reducing your carbon footprint: priceless.

How safe is the VortX EcoFilter? MUCH SAFER

Every year chaff collectors and exhaust ducts catch on fire and cause millions of dollars of damage and injury. A properly installed and maintained EcoFilter prevents the rapid buildup of creosote, oils and other flammable materials inside the cyclone and exhaust duct. There is little to burn and it is wet.

The outside of the cyclone and exhaust stack stay below 140 F, reducing the risk of personal injury. Should you experience a drum fire, it cannot propagate beyond the EcoFilter inlet.

Is the EcoFilter difficult to maintain? NO

Chaff collects in a sieve and is easily emptied while you roast. At the end of the day, wastewater is drained and refilled, the filters are wiped clean, and the system and is run for a few minutes to ensure the nozzles have only clean water in them. A system inspection is recommended monthly for the first several months until you see your own maintenance pattern emerge.

How durable is the VortX EcoFilter? A THOUSAND YEARS?

Type 304 stainless steel can last up to 9000 times longer than carbon steel. Therefore, the cyclone and all wetted surfaces are 304 stainless steel.

What happens if the EcoFilter stops working before I finish a roast? NOTHING

The EcoFilter is a fail-safe product. If it stops working at any time during the roast, simply finish the roast and then investigate the cause.

Is it difficult to monitor the EcoFilter’s performance? NO

Three line-of-sight gauges tell you if the VortX is operating correctly:

  • Stack Temperature
  • Water pressure
  • Water volume
Are the wet chaff or wastewater hazardous? NO

The chaff is an excellent nutrient-rich soil amendment. It is compact and easy to transport or dispose of. The wastewater is not toxic or hazardous and can be used to water gardens or put down any water drain.

Can VortX help me get an operating permit? YES

VortX will help any customer apply for an operating permit from their local clean air authority by providing test data on emissions from air treated in the EcoFilter and directly answering their questions. As clean air authorities work to maintain clean air standards in the face of the need for massive reductions in emissions of methane and carbon dioxide created by afterburners, these authorities are showing tremendous interest in our solution to air pollution. While VortX cannot guarantee a permit will be issued, we will support your efforts to obtain one.
