Zero-Air-Generators
Features & Benefits
Technical Details For GC-FID there are six new models in the SMART series to produce zero air of the highest possible purity from compressed air. All models are absolutely noiseless and easy to install. The generators continously produce zero-air with hydrocarbon content < 0,1 ppm (measured as methane). They cover requirements for zero-air for up to 160 FID´s at outlet pressures between 2 bar and 10 bar. Using modern filter technology to remove particles, water and oil-vapors, the generator works with your compressed air. The catalytical chamber stage than removes disturbing traces of hydrocarbon. Maximum air flow rate, gas/air supply, required temperature in the reactor and electrical requirements are checked and supervised continiously. If there is a fault or crossover of the critical values an alarm is given immediately via relays corresponding to ISO 9000. If the generators detect a fault they automatically switch over to back-up gas cylinders or cut off the gas delivery to the lab. The user can then eliminate the fault and reset the alarm. Even the biggest model delivers up to 50 l/min zero air of constant high purity, within 10 minutes of starting. | Benefits
Compressed air supply All models of the SMART series are available with an external low noise and oil-less air compressor for permanent use (< 55 dbA). |

Options
- Flowmeter
- Pressure-gauge
- Temperature OK/stａnd by (LED view of catalyst)
- Potentialfree contacts without hold-function
Voltage Failure
Failure Air/ Gas- Supply (1 to 8 bar adjustable)
Overheating in the Catalytical Chamber
Exceed of maximum
Flow Capacity - Potentialfree contacts with hold-function
Example: In case of "Failure Air/Gas-Supply", which means no pressure out of the compressor, immediately an alarm is given via relais. After elimination of the fault the alarm has to be quit manually and the generator starts service again. - Reaction to fault detection
gas delivery cut-off
automatic switchover to back-up cylinders
