Unique Build & Innovation

Yellowstone FFE units outperform the competition for a reason. Through our proprietary modular approach to design, our teams consistently innovate at every stage of the FFE process (heating, evaporation, cooling) and output industry leading technology at every stage of the evaporation process.

Because others do everything. We do FFE.


Easy To Use

Switch it on & turn it up, it’s that easy.

Startup of a Yellowstone FFE requires turning three switches and setting the dosing rate. After that, operators just need to monitor and occasionally tweak system conditions to optimize the product output.



No Pressure

No steam, no added costs, no pressure.

Unlike steam generators, Yellowstone’s onboard heating system isn’t subject to pressure vessel regulations, doesn’t require additional investment, doesn’t expand the machine’s footprint, and does not require complicated installs and servicing. Simplicity in the heating system means less chance for down-time.


Continuous Operation

Our Falling Film Evaporator integrates automatic control systems for ease of use and to decrease processing times. The dosing pump and automated draining systems allow for continuous operation with minimal operator input. Our proven evaporation and condensation rates ensure that you will be left with high purity concentrates and solvents, achieved at rapid speeds.

Chill Without The Chiller

Patent-pending technology works to rapidly condense all the solvent vapor. This is by far the most economical and energy-efficient condenser available in the industry, as it replaces pricey chillers with a radiator requiring less energy input.

Our FFE Condenser

Higher surface area means more effective heat transfer. This is what makes our Diffusion Condenser the most efficient condenser on the market. Vapor bubbles are completely enveloped in cooled solvent, creating the highest possible surface interaction. This drastically reduces the cooling required, completely eliminating the need for chillers.

Paired With

Our Fluid Cooler

In order to maintain the condenser temperature, the condenser reservoir is constantly cooled with a circulated water loop. The system heat is then removed as the water travels through an outdoor radiator assembly. This is a much more efficient and affordable cooling method than chiller-based systems.

5 Year Energy Cost Comparison

Graph comparing the energy costs over 5 years between the Yellowstone condenser and a comparable chiller. After 5 years, the energy cost for the Yellowstone condenser is $2695 and the comparable chiller is $56160.

Our Condenser's Energy Usage 2.16kw @ $0.12/kWh @ 40 hrs/wk for 52 weeks/year = $539

Comparable Chiller's Energy Usage 45kw @ $0.12/kWh @ 40 hrs/wk for 52 weeks/year = $11,232

Safety First

When working in hazardous locations, failure is unforgiving and consequences are dire. Because of this, safety is at the forefront of our engineering team’s design decisions. Our designs have multiple redundant fail safe mechanisms to ensure that hazards to the operator are statistically eliminated. We perform sensitive FMEA (Failure Modes and Effects Analysis) and design our machines such in the event of a component failure, we can rely on alternate safety devices.
