The "RTCS-02" is an educational refrigeration cycle simulation that allows you to learn the principles and mechanisms of refrigeration and air conditioning. The compressor, condenser, evaporator, and other components are arranged in a compact tabletop frame with a layout that is easy to see and understand. By operating the fan motor with the control unit's switch and opening and closing the valves in the piping, you can simulate air conditioning failures and observe changes in pressure with the built-in gauges. 【Features】 - Experience the differences in piping temperatures and the principles behind the creation of "warm air" and "cold air" by actually running the system. - Simulate air conditioning failures. - Observe changes in pressure with the built-in gauges. - Conduct education on tables or workbenches in conference rooms or training rooms. *For more details, please refer to the PDF materials or feel free to contact us.

The "Digital CO2 Manifold" is a dedicated gauge for performing vacuum and charging when connected to equipment using CO2 refrigerant. The vacuum gauge has a pressure resistance of up to 10 MPa, so there is no risk of damage to the vacuum gauge due to malfunction of the blow-off valve, allowing for safe use. Unlike conventional analog manifolds, both the vacuum gauge and high-pressure gauge are highly shock-resistant and have a resolution of 100 divisions, ensuring that even minor changes are not missed. 【Features】 ■ Covers the measurement range required for CO2 - Low-pressure digital gauge: -0.1 MPa to 9.9 MPa - High-pressure low-pressure digital gauge: 0 MPa to 25 MPa ■ With a resolution of 100 divisions, it does not miss even minor changes ■ A handle that displays the opening and closing of the valve is adopted for safety considerations *For more details, please refer to the PDF document or feel free to contact us.

The US275 is a carbon cleaner that emits ultrasound from 10 ultrasonic generating units located at the bottom of the cleaning tank, creating vibrations at a rate of 40,000 times per second in the cleaning solution. The process of expansion (vacuum bubbles) → contraction → rupture (cavitation) → shock wave generation → cleaning effect is continuously repeated (cavitation effect), allowing for powerful cleaning of carbon deposits on automotive parts without damaging the base material, thanks to the synergistic cleaning effect with the dedicated solvent (HC01). 【Features】 ■ Ultrasonic output (Power) can be adjusted from optimized power levels of 30% to 100% ■ Rust-resistant design with stainless steel housing and stainless steel cleaning tank and lid ■ Waterproof, seamless molded tank with excellent welding gaps ■ Moisture-proof base design ■ Professional-grade with industrial IC and 10 ultrasonic generating units *For more details, please download the PDF or contact us.

The "LLC Vacuum Charger" is a groundbreaking product that creates a vacuum state using a vacuum pump based on the ejector principle, allowing for the injection of LLC without creating air pockets in the radiator. It adopts a double ejector mechanism that achieves a vacuum level comparable to that of outer space, which traditional ejectors could not attain. This mechanism enables vacuum injection at a high-level vacuum reaching -0.098MPa (735mmHg), significantly surpassing the conventional ejector vacuum range of -0.07MPa to -0.089MPa. 【Features】 ■ Overwhelming suction power with a vacuum reach of over 98% ■ Quick cooling water injection operation time of about 60 seconds ■ Smooth operation without creating air pockets ■ LLC replacement can be done in a short time and easily *For more details, please download the PDF or contact us.
