Solvent Recovery Units Overview
In-House Distillation Advantages Compared to Outside Reclamation Services
Finish Thompson equipment can produce a purer product
Higher recovery yields
You control your distillation schedule
Cradle to grave control over process {Resource Conservation Recovery Act (RCRA) has put the responsibility on generators for its transportation, storage, and disposal}
Reduced liabilities for transportation and disposal of hazardous waste
How it Works
1. Boiler Chamber Filled- Solvent is poured or pumped into the boiling chamber, which the operator lines with a standard Stilbag.
2. Solvent Heated- The chamber lid is sealed and power sent to the unit. The encapsulated heater radiates heat through the conductive walls of the chamber heating the solvent.
3. Vapors are Formed- Vapor from the boiling solvent travels through the vapor tube to a water-cooled shell-and-tube condenser.
4. Vapors Condense- The vapor condenses into a 99% plus pure distillate. The distillate is gravity flowed into an approved 15 or 55 gallon drum (customer supplied).
5. Cycle Completed- When a visual check reveals no further distillate available the operator shuts the unit down and allows it to cool.
6. Residue Removed- After cooling, the remaining residue is removed via the Stilbag.
LS Solvent Recovery Unit Series Features
Safety Finish Thompson solvent recovery units are built to Class I, Division I, Group D (NEMA 7) standards of the National Electrical Code. Explosion proof components are UL listed. All UL units have CSA approval.
Condenser Water Flow Switch Distillation unit only operates when sufficient cooling water is present. Interruption of water turns heater off. (Not available on the LS-JrE model)
Dual Thermostat Dual thermostats ensure unit temperature does not exceed the recommendation for heater temperature in a Class I, Division I, Group D environment.
Patented Encapsulated Heating Element The heating element is encapsulated within the vessels bottom ensuring direct heat to 100% of the vessel. The heater on all LS Solvent Recovery Unit Series units carries a life time warranty.
Residue Removal System Convenient Stilbags capture residue for easy disposal. Optional Stilpan is available.
Quick Cool Coil Distillation tank cools quickly, so it can be used by multiple shifts. (Optional on LS-55STE
Solid State Design ensures reliable accurate operation
Fully Insulated Distillation tank and lid are completely insulated with ceramic fiber for heat retention
Vacuum Capability An optional vacuum system can be added to any LS Solvent Recovery Unit Series solvent recovery unit allowing recovery of solvents with boiling points up to 500°F
Little Still JrE 
Designed for small shops, Finish Thompsons Little Still JrE processes 3-5 gallons per shift. JrE has a small footprint and can be easily stored. An optional exhaust hood is available to contain and exhaust vapors.
