The use of Indirect Thermal Desorption with temperatures up to 400 °C through thermal oil whilst under parallel vacuum conditions is uniquely realised by the econ VacuDry System. To demonstrate the capability of the process and to be able to analyse the input material with regard to it’s suitability for Thermal Desorption, econ industries has designed a series of sophisticated laboratory units. Furthermore, the econ Lab consists of testing equipment for blending and stabilisation/solidification. Further process technologies such as centrifugation, sieving, magnetic separation, etc. may be added in cooperation with our partners.

All econ Lab units are fabricated as mobile units to allow us to carry out “in-situ” trials at the client’s own facility. The complete supervision will be carried out by econ industries' process engineers; on-site we only need electrical power, cooling water (~25 °C) and nitrogen (only for explosive matters).

• Available lab equipment: Vacuum evaporators (max. 400 °C) and mixers in varying design and with batch sizes up to 150 liters; appropriate condensation and vapour handling units, Static vacuum oven (max. 500°C) with 1 liter capacity, Various mechanical separation technologies.
• Heating systems: Thermal oil up to 400°C, steam up to 10 bar
• Operating pressure: < 10 mbar absolute pressure, if required
• Required material quality: Grain size up to 20 mm – free of extraneous material

• Lab tests allow the involved engineers - econ industries and client - to research all pertinent process data
• Verification of future plant size, throughput capacity, required operating hours, etc.
• Detailed calculation of operating expenses from energy and utilities consumption, etc.
• Agreement of identification of final quality of treated products, from separated or blended fractions
• Research of material characteristics for establishing a suitable wear protection
• Studying conveying properties, to select appropriate conveying and dosing equipment
