Disilane Gas Detector

$2,170.00

Product Summary

The PureAire Disilane Fixed Gas Detector is engineered to provide continuous, real-time monitoring of disilane (Si₂H₆) gas. When paired with a renewable toxic gas sensor specifically calibrated for disilane in parts-per-million (ppm), this system offers reliable performance and fast leak detection in sensitive environments.

Disilane is primarily used in semiconductor fabrication, flat panel display production, and photovoltaic industries for processes like chemical vapor deposition (CVD). Its highly reactive and pyrophoric nature, combined with toxicity concerns, make leak detection critical for maintaining cleanroom safety and process control.

PureAire’s disilane sensors are designed for long operational life—up to 8 years in clean environments typical of high-tech manufacturing. Sensors are also rechargeable with on-site electrolyte, helping facilities avoid unnecessary downtime and reducing cost of ownership.

Whether you’re operating a semiconductor fab or a precision materials lab, PureAire provides a robust, easy-to-maintain gas monitoring solution that keeps your personnel safe and your systems running efficiently.

Please note that because of the nature of this product, the lead time is typically 2-3 days but may be up to one week. We will make every effort to ship your order as soon as possible.

The PureAire Disilane Gas Detector is a compact gas monitor that’s ideal for protecting workers from toxic and corrosive gas exposure in the workplace. It consists of a transmitter/controller connected to a dedicated, renewable, disilane gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone unit, the Disilane Gas Detector can also be connected to any programmable logic controller or SCADA system. PureAire also manufactures toxic gas detectors with a remote sensor.

The heart of the Disilane Gas Detector system is a smart, renewable, disilane sensor cell programmed with specific gas and measurement range information. When servicing the sensors, they can be recharged with fresh electrolyte and dynamically gas-calibrated in the maintenance shop away from the transmitter.

Affordable, Low-Cost Gas Monitoring

When it comes to keeping operational costs low, the PureAire Disilane Gas Detector stands out. Offering the lowest annual maintenance costs on the market, this system uses renewable disilane sensors that can be easily recharged in the field with electrolyte. This innovative feature reduces costs to just 20% of the price of disposable sensor systems, saving you hundreds of dollars in annual service and maintenance. With routine materials averaging $70 per year, it’s a smart choice for long-term savings.

Effortless Stand-Alone Monitoring

The Disilane Gas Detector is designed for simplicity and efficiency. It operates completely stand-alone, so all you need to do is mount it on the wall near the risk area and connect the regulated power supply to any 115VAC 60Hz or 220VAC 50Hz outlet. In no time, you’ll be actively monitoring disilane levels. With built-in horn and LED alarm indicators, the system provides immediate alerts to hazardous conditions, ensuring quick action. Plus, individual alarm and fault relays let you connect to remote alarms or control systems. The analog 4- 20mA output continuously delivers real-time data to remote PLC and SCADA systems, giving you full control and insight.

Always-on Supervision for Maximum Safety

The smart circuitry in the Disilane Gas Detector is continuously monitored around the clock, ensuring reliable operation 24/7. If a system error occurs, the detector immediately sends alerts via its analog output and fault relay, notifying control room personnel of the issue. The integrated microcontroller makes routine calibration and maintenance a breeze — just remove the sensor from the transmitter, enter calibration data directly into the sensor electronics, and reattach it. The data is automatically transferred to the transmitter when plugged back in, making maintenance straightforward and hassle-free.
