Want Effective Solvent Cleaning Without the High Cost?

Fully automatic vacuum hydrocarbon ultrasonic cleaning machines come with a high purchase cost. Many customers want solvent (hydrocarbon) cleaning performance but cannot afford the full-automatic investment.

To solve this problem, GTKCLEAN engineers developed the Semi-Automated Solvent Cleaning Machine. It is a cost-effective semi-automated vacuum solvent (hydrocarbon) ultrasonic cleaning machine.

Workers only need to load and unload parts baskets manually. All other processes — cleaning, rinsing, drying, and solvent recovery — are fully automatic. They work exactly the same as in full-automatic vacuum hydrocarbon ultrasonic cleaning machines.

This machine supports eco-friendly cleaning for all kinds of parts. It can work alongside ultrasonic cleaning lines or run independently. Using vacuum environment and hydrocarbon solvent, it delivers strong cleaning precision, ease of use, and safety.

Our solvent (hydrocarbon) cleaning machine is widely applied to precision parts cleaning across manufacturing, electronics, automotive and other demanding industries. It provides superior value and outstanding cost-effectiveness for your production process.

Compact Vacuum Solvent Ultrasonic Cleaning Machine

This machine utilizes hydrocarbon or eco‑friendly solvents, integrating ultrasonic cavitation, spray cleaning, basket shaking, and vacuum technology into one system. The outcome is superior cleaning precision, zero water spots, and low odor emissions.

As a compact, all‑in‑one vacuum ultrasonic cleaning system, it operates fully automatically after loading. It delivers reliable performance, high efficiency, enhanced safety, and low operating costs.

Cleaning Process:

The semi-automated solvent cleaning machine is a fully enclosed, multi-stage vacuum cleaning system. All processes are completed within a single sealed chamber:

1. 1. Rough cleaning
2. 2. Fine cleaning
3. 3. Vapor washing
4. 4. Vacuum drying
