Batch-Type Solvent Recyclers

Kresco’s batch-type solvent recyclers are designed to provide a safe, efficient, and automated solution for recovering and reusing contaminated industrial solvents. The SR Series performs fully automated solvent distillation cycles every six hours, helping manufacturers reduce solvent consumption, minimize waste disposal costs, and improve overall cleaning process efficiency.

Available in tank capacities ranging from 30 to 240 liters, Kresco’s industrial solvent recycling systems deliver reliable solvent recovery performance for a wide variety of applications, including parts cleaning, paint equipment cleaning, and industrial maintenance operations. Built for ease of operation and long-term reliability, SR Series solvent distillation equipment helps businesses lower operating costs while supporting more sustainable manufacturing practices.

Advantages of our solvent recyclers

How do Solvent Distillers Work?

Kresco’s line of Solvent Recyclers is the ideal solution for solvent distillation processes in industrial applications with optimal efficiency, safety, and consistent quality.

It provides a controlled environment for the procedure of separating various solvent blends and chemical substances in order to achieve the highest quality standards and process requirements.

Depending on the components included in the substance, one should expect recovery rates yielding from 95% to 99.9%!

Most of our customers have gained a Return on Investment (ROI) in as little as 4 to 12 months!

Standard features

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 Kresco. 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.

Optional features

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 for 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.
