Liquid source temperature controller
VTC17 series
The Vymore VTC17 Series Temperature Controller, also known as a bubbler, maintains your liquid source chemical or precursor at a precise and stable temperature. Its front-loading design offers easy access to ampoules, even in space-constrained environments. Advanced alarms and warning systems enhance user safety and help anticipate potential issues before they occur. With a proven track record, the VTC17 delivers exceptional reliability and long-term durability. Designed as a drop-in replacement for older generations of bubblers, the VTC17 offers fast delivery—typically within weeks—and responsive, around-the-clock support.

Features that set us apart
Fast PID control
The Vymore VTC17 bubbler quickly detects temperature changes in the precursor, particularly at the start of the bubbling process. Its fast-responding PID controller ensures stable and precise temperature regulation.
Exchangeable temperature probe
The temperature probe is exchangeable without requiring recalibration. A high-quality push-pull connector ensures easy installation and reliable liquid source temperature measurement. Incorrect placement of the probe is automatically detected and indicated.
Analog and fieldbus communication
Analog communication is handled via a D-sub-25 connector. The analog signals are galvanically isolated from the power supply, eliminating the risk of unwanted ground loops. Ethernet fieldbus communication, supporting the most common Ethernet protocols, is available through two RJ45 connectors. In the event of an Ethernet or analog malfunction, or an unexpected power reset, the VTC17 liquid source temperature controller will continue to operate safely and independently using the last stored data values.
Standalone temperature controller
The all-in-one precursor temperature control solution operates on DC voltage, eliminating the need for hazardous high-voltage connections nearby. The bubbler’s DC power supply is integrated with the system’s emergency circuit, ensuring an immediate shutdown in case of an emergency.

Bubbler methode
A liquid source temperature controller is part of an evaporation system. A carrier gas—such as nitrogen—is passed through the liquid, picking up a known amount of chemical vapor. Because the chemical’s temperature is precisely controlled, the resulting vapor pressure is accurately defined. This technique ensures a consistent and predictable carrier gas–vapor mixture.
