Oil & Ethanol Recovery Systems

There is no doubt that alcohol recovery has become one of the biggest bottlenecks in the industrial cannabis extraction industry. The Maratek Oil & Ethanol Recovery Series are the engineered solution to this exact problem. With four labor-intensive processes all built into one system, the Maratek OERS series: OERS-C and OERS-SC can automate your entire downstream process with no laborer required during operation. Our Patented technology can recover 99+% of your ethanol, automatically reproof/dewater your ethanol in line, and can also decarboxylate your cannabis oils all within the same unit.

With over 50 years of engineering experience, Maratek has brought its experience and design to suit the cannabis industry perfectly. 

Maratek's OERS equipment performs four steps in one automatic process. Bulk ethanol recovery, final ethanol recovery, ethanol reproofing/dewatering, and decarboxylation are all performed in a single automatic process with minimal operator time needed.

All of Maratek's equipment is backed up with comprehensive testing, hard science, and money backed guarantee based on total daily 95% ethanol extraction solution processed. A 24 hour cycle includes filling, heating up, continuously topping off the still, and finally a full boil-down to solvent free oil, which is unachievable with falling film systems.

Maratek's OERS equipment has been engineered to minimize the effects of heat loss and improved heat transfer efficiencies. Our uptime guarantees utilize our secure remote troubleshooting technology and the ability to dispatch a technician within 24 hours if your equipment needs on-site service. Plus, we offer lifetime remote service at no extra cost. Download a brochure or request a quote today!

What Our Clients Say

We chose Maratek for their long-standing reputation in the industrial plant fabrication industry. Their willingness to work with our redesign parameters and special needs made it so we are able to produce more high-grade cannabis oil per sq ft than almost any other lab in the world. Their techs answer when I call and have walked me through several complex troubleshooting exercises and have gotten me replacement parts quickly. This unit is beyond reliable. We have ran our evaporator almost 24-7 for the last year and have very few problems beyond simple wear parts. I highly recommend Maratek.

Maratek has been a pleasure to work with since the day we first connected. I was already producing cannabis oil out of my facility in Oregon, when I saw some Maratek equipment at an MJBizCon show. I had been having a huge bottleneck in the recovery section of my processing line from using a falling film system, and a rotary evaporator. There were also issues of getting oil recovered with my ethanol, making it have a yellowish-orange tinge. After purchasing the Maratek C500 system, which was properly sized for my operation, the bottleneck disappeared and the system automatically combined the falling film, rotary evaporator, AND decarboxylation steps in one unit. My operators literally just ensure there is an infeed, a place for the outfeed, and set it and forget it. The Maratek system had built in a "mist eliminator" to ensure that there was no worry of oil entrainment within my recovered ethanol. Their quality of equipment, along with confidence to give throughput guarantees made it easy for me to decide.
