ABSOLUTE™ 

Temperature Control System 

DESCRIPTION 

The ABSOLUTETM Temperature Control System provides accurate and stable 

temperature control of liquid source chemicals. Five different models provide 

temperature control through the range of 10°- 90°C, with an accuracy of ± 0.2°C. 

FEATURES AND BENEFITS 

• Modular design for easy installation 

• Microprocessor-based control circuitry for accurate and stable temperature control 

• Electronic and visual (sight glass) level sense (for monitoring chemical levels) 

• Removable source cup permits safe container installation from the front of the unit 

• Full range of safety interlocks 

• DDC interface for remote control and monitoring 

• Holds 1500cc quartz or 1.2 liter stainless steel containers 

• Stainless steel versions incorporate level sense and integrated lid heater 

• Trans-LC® version eliminates all spark sources and reduces over temperature cutout 

interlock

ATCS with 1500cc patented 

breakseal quartz bubbler. 

APPLICATIONS 

• Temperature control for CVD source chemicals 

(i.e. TEOS, ZTOMCATS®, LTO-410™, 

TMB,TMPI) 

• Temperature control for diffusion and oxide 

passivation source chemicals (i.e. Trans-LC, 

TCA, POCl3, and PBr3 and BBr3)

LIQUID LEVEL SENSE

Quartz Breakseal Container:

Discrete level sensors at 100%, 50%, 25% and 15%. 

Backlit sight glass for visual inspection of liquid level. 

Stainless Steel Container: 

Discrete level sensors for indications at 100%, 75% and 15%. 

ALARMS 

Liquid Level Alarm:

Alarm activated when liquid level reaches 15% full. 

Temperature Alarm:

Alarm is activated when the sensed temperature is not within ± 2°C of the temperature setpoint. 

(± 5°C for Trans-LC unit) 

Alarm Indicators:

All alarm conditions generate an audio alarm, flashing LED display with alarm condition, and an alarm output through 

the DDC interface. (The audio alarm can be silenced for 30 minute intervals.)
