Batch-Type Solvent Recyclers

SR Series Batch-Type Solvent Recyclers can perform a fully automated distillation processes every six hours and they are available in tank capacities of 30, 60, 120, 180 and 240 liters.


Durable: Built with robust, corrosion-free stainless-steel tanks.

Virtually Maintenance-Free: Require low maintenance and supervision, a simple 4-hour maintenance routine every 2,000 hours of operation.

Certified in North America: Certified to UL standard 2208 and CSA C22.2 No. 30 in Canada and the U.S. for class I, Div.1, Group D hazardous locations, and meets NFPA codes 30, 33, 70.

Cost-effective: Most of our clients have achieved a return on investment (ROI) in as little as 4 to 12 months!

Fully Automated Process: Operate on a fully automated process assisted by a PLC with predetermined parameter settings and built-in alarm signals.

Guaranteed: Backed up by industry’s leading 2-year manufacturer warranty.


Distillation Tank

Built with strong 304 stainless steel construction and insulated with 4’’ polyurethane on side wall and bottom. Our distillation vessels are tightly sealed with a locking lever and replaceable cover seals for safe and optimal working conditions.

Control Panel

Fully automated process assisted with an intuitive programmable logic controller (PLC), proprietary of IST. Security levels, alarm signals, and maintenance reminders are implemented into the software for peace of mind use.

Indirect Heating

Heating system consists of explosion-proof heating element impregnated in exclusive formula – high-temperature thermal oil suitable for solvent with up-to 180°C / 355°F distillation point.

High-Efficiency Condenser

Coil condenser equipped with high-efficiency, explosion-proof motor fan provides quick cool down and ensures the system is working under acceptable temperature.


Vacuum Assisted Process

Vacuum system decreases the boiling point of certain solvents by 20 to 30%, thereby leading to less energy consumption and better distillation process overall. Also required heavier-than-air solvent distillation process.

Stainless Steel Upgrade Kit

All stainless-steel condenser and piping upgrade kit is available to provide additional protection from highly corrosive solvents.

Auto-Fill System

Auto-fill kits eliminates the need for operator’s intervention. It includes a diaphragm pump, transfer hoses, and a level switch, all controlled by fill sequence timers built-in the software.

External Light Box

Allows remote monitoring of the recycler from a centralized control room. Indicates when the system is running, cooling down, malfunctioning, or ready for a new batch.

High Temperature Kit

Consists of high temperature synthetic thermal oil, high performance vacuum generator and larger expansion oil tank for heating solvent with distillation point above 180°C / 356°F. Maximum operating temperature is 225 °C / 437 °F.

Sludge Removal Basket and Lifting Arm

The sludge removal basket paired with a lifting arm equipped with a hand crank significantly reduces the level of efforts required to remove the sludge bag from the boiler after the distillation cycle.

Sludge Monitoring Safety Device

Recommended when processing highly volatile solvent, the sludge monitoring safety device would immediately shut off the heater, switch the unit to cool down, and trigger a sprinkler system inside the boiler when the sludge reaches a preset limit temperature during cycle.

Oil Cooling Unit

This auxiliary system can rapidly lower the oil temperature by circulating it through a multi-plate heat exchanger and a condensing system so the operator can proceed with a new batch faster.


Available boiler capacities of 30, 60, 120, 180 and 240 liters, each SR Series units can perform up to 4 recycling cycles per day (4-6 hours each).
