SEMPA’s GAS’BOT family of specialty gas cabinets have been designed meeting all kinds of different applications and requirements.
We do offer three different basic versions (SMART, PRO, EXPERT) with a huge variety of optional features which enables us to precisely adapt the cabinet solution to your specific technical and budgetary requirements. All classes of cabinets have in common a stringent focus on safety, streamlined design and the pick of durable and high quality components, following the SEMPA quality promise.
The GAS’BOT family of supply systems is based on several decades of experience and know how in handling toxic, pyrophoric or corrosive specialty gases. A high degree of flexibility and several connectivity options allow easy integration into your LAB or FAB.
GAS'BOT is designed and built to the highest quality standards to meet the high demands of our customers. Primarily built for the requirements of the semiconductor industry, GAS'BOT is also suitable for many other industries and applications.
Ultra high purity components
Easy to maintain
Many options help to configure the system exactly to your application and type of gas. Please contact us to customize your GAS'BOT. Our experienced engineers will be happy to assist you.
Numerous dangerous gases are commonly use. GAS'BOT has a number of safety options to protect against risk of fire, corrosion or accidential release of gas.

Every GAS'BOT is very versatile. Any bottle size, type of valve or connection can be accomodated through a huge range of adapters or a custom build feature. Please ask your SEMPA expert for your specific solution.
If flammable or pyrophoric gases are applied fire protection is mandatory. A smoke sensor is in general first detector of choice as usually fumes and particles will be generated already if only small amounts of such energetic materials do react. Can be combined with a UV-IR sensor to have two independent methods for fire detection.
For a variety of dangerous gases specific, highly sensitive sensors are available to detect traces of molecules. The sensor is installed in the exhaust duct at the cabinet. A forced ventilation ensures that cabinet atmosphere gets continously directed to the gas sensor.
The SEMPA emergency cylinder shutter is a highly recommended safety component for dangerous gases which are supplied in gas bottles featuring manually operated valves. ECS-1 is applied on the manual valve and automatically shuts the valve within 100ms in case of emergency.
Coaxial Piping and Monitoring:
Corrosive gases may react with stainless steel tubing. In order to monitor corrosion and to protect the facility against gas leakage coaxial piping can be applied. The gas flows through the inner tubing whereas the outer tubing is continously pressure monitored. Both break of inner tube as well as outer tube can be detected.
Gases which can form explosive mixtures in air need to be protected against spark formations from electric components like switches or formation of electric discharge. Building the system accoring ATEX, meaning explosion proof rules out such possible sources of ignition.
For certain processes, gases must be specificall temperature controlled. A variety of options adapts your GAS'BOT to the sepcific needs.

For liquified gases like propane thermodynamic cooling in case of expansion (Joule-Thomson Effect) could significantly affect the evaporation rates. To ensure stable flows of gases cylinder heating can be applied to compensate for Joule-Thomson effect.
Certain vacuum deposition processes require for optimal conditions liquified gases like HF or WF6 to be specifically cooled. Every GAS'BOT can be equipped with cylinder cooling sleeves including temperature monitoring in order to keep gas bottles in the optimal temperature range.
During pressure expansion of gases it can happen that components like pressure regulators may freeze (Joule-Thomson-Effect). The optional panel heating is an efficient way to protect components from unintentional freezing and it avoids ambient moisture to condensate on cold components.
For some liquified gases and special process conditions (like HFAc) trace heating of supply lines from bottle connection to point of use may be required. The line heating prevents condensation hence ensure stable and safe process conditions.
Certain processes require special components, materials of construction or an adapted design. GAS'BOT can be customized to any gas and process requirement.

Heavy Gas Optimization:
GAS'BOT can be optimized for gases having high specific gravity (e.g. WF6). Such gases may exhibit challenges for stable and high flows. This upgrade option enables an optimized gas supply to your processes.
Higher Alloy Steel:
Highly corrosive gases such as HFAc or fluorine attack welding seams and 316L stainless steel. Process lines can optionally be build in higher alloy steels like hastelloy or monel to avoid corrosion and process contamination.
In order to monitor fill levels of iquified gas bottles a scale is a effective measurement device. The scale can be installed at any GAS'BOT and fill level is monitored and displayed on the HMI.
Custom Cylinder: Every GAS'BOT is very versatile. Any bottle size, type of valve or connection can be accomodated through a huge range of adapters or a custom build feature. Please ask your SEMPA expert for your specific solution.
