General Specs

Mass Volume Application

RotoVaps have been the industry standard for low volume production due to their inexpensive cost; however, the slow recovery rate, large footprint, and higher labor-to-output cost require a more efficient way to handle high volumes of production. As outlined above, the AutoVap AV-15 can operate at a similar output level of 10 20L RotoVaps, while dramatically reducing overall footprint, energy costs, consumable costs, staff required to operate the equipment, and all the headache.

For mass volume production, the AutoVap Falling Film Evaporator is the most efficient and highest quality ethanol recovery system available on the market. The AutoVap allows you to continuously feed material and recover ethanol.


All fabrication is performed in the U.S.A. and China, and assembly shall be performed in the U.S.A. The materials used are Viton and PTFE gaskets, 3A sanitary stainless steel 304 tri-clamp fittings, 316L Swagelok fittings, and borosilicate glass. All wetted components have been approved by the FDA for food and beverage use.

System Rating

The entire system will be rated for a maximum allowable working pressure of -29 in Hg to 15 psi, and certified systems affixed with a 15psi ASME pressure relief valve that is vented to the atmosphere.

The vessels and components are manufactured to ASME specifications, however do not bare an ASME stamp and due to standard operational pressures are not considered a pressure vessel as per Section VIII of the ASME Boiler and Pressure Vessel Code. The aforementioned relief valves ensure the system will not exceed this rating. The system is independently inspected before shipment or installation to ensure a maximum leak rate of 5 in Hg (vacuum) per hour, and shall not leak any detectable amount of ethanol vapor during normal operation.

The system has been designed to comply with the current laws governing chemical extraction in California, outlined in the next section of this document.

Ancillary Heating and Cooling

The heating and cooling components for the AV-15 shall be housed in a separate location depending on the governing municipality legislature. These consist of (1) ChillKing 5 ton commercial chiller, (1) Hubbell electric tankless or Navien LPG/Natural Gas tankless heater, (1) Chugger fluid pump, (1) Welch 2061 Diaphragm Vacuum Pump, and (1) PolyScience -40C 28L chiller, all of which bear an ETL or uL listing. It is highly recommended the ChillKing unit is placed outside or given adequate ventilation to exhaust the heat produced by it, outlined in their operation manual.

Warranty and Support


TruSteel LLC shall warranty all components against defects in workmanship and material for a period of one (1) year from date of start-up, provided that the unit is installed and operated within the scope of the system design and operating capability. Labor is not covered under warranty. Each AutoVap shall be shipped with a complete set of installation and operating instructions including spare parts list and drawing.
