VDM300

Product catalog summary

Overview: The Brooks VDM300 is a vapor delivery module designed for the precise delivery of ultra-high purity deionized water vapor. It features a power-efficient design that operates without a carrier gas, utilizing advanced digital control and diagnostic features.

Specifications: The VDM300 offers a full-scale range of 3000 sccm with a turndown ratio of 20:1. It provides a step response time of ≤ 2 seconds and an accuracy of ±1.0% of the setpoint for >10% full scale. The module supports both analog and EtherCAT communication interfaces.

Mechanical and Electrical Features: The VDM300 operates at lower temperatures to improve corrosion resistance and features optimized design for flushing and draining. It requires a DC power supply of ±15 Vdc or an AC supply of 208-230 Vac. The module is equipped with a Micro USB diagnostic port and supports various fitting options.

Certifications: The VDM300 complies with several directives including EMC Directive 2014/30/EU, Low Voltage Directive 2014/35/EC, RoHS Directive 2011/65/EU, and REACH Directive EC 1907/2006. It also adheres to the SEMI E54.20-1108 standard for EtherCAT communication.

Environmental Conditions: The module operates within an ambient temperature range of 15°C to 45°C and a humidity range of 0 to 95% RH, non-condensing. It requires a DI water supply pressure of 10 to 40 psig and a maximum outlet pressure of ≤ 200 Torr.

Service and Support: Brooks Instrument offers global service and support, including start-up service and in-situ calibration. They provide customer seminars and training to ensure optimal use of their products.

Model Code: The VDM300 model code includes options for fluid type, flow range, supply voltage, fittings, mounting, and pinout options, allowing customization based on specific requirements.

DATA SHEET Vapor Delivery VDM300 High-Accuracy, Deionized Water Vapor Delivery Module VDM300 Vapor Delivery Module The Brooks VDM300 vapor delivery module is a self-contained module for the highly accurate delivery of undiluted, ultra-high purity, deionized (DI) water vapor. The power efficient design allows for low temperature, ultra-high purity vapor generation without carrier gas. The VDM300 utilizes a proven vapor delivery technique and combines it with advanced digital control and integrated diagnostic features in a small, convenient package. Designed for advanced strip and post-metal etch passivation processes, the VDM300 delivers improved accuracy, wide control range and lower power consumption compared to flash evaporation systems. Based on proven thermal mass flow measurement techniques, the VDM300 produces vapor in a passivated titanium vessel in a non-super heated vapor stage, reducing the aggressive effects of deionized water, for improved reliability and cleaner operation. The VDM300 offers both analog (default) and EtherCAT (optional) communication interfaces. In addition, it provides user-friendly data logging and diagnostic features via an independent Micro USB service port and intuitive graphic user interface. Direct water vapor measurement with superior flow accuracy Based on proven, reliable thermal mass flow measurement and control technique Connects directly to the house Deionized Water supply Highly tolerant of varying water supply pressure Operates at lower temperatures (non-super heated state) Improved corrosion resistance Optimized design for flushing and draining Ensures cleaner operation View VDM300 Product Page
