6.3.3 Gas connections
Risk of explosion!
Non-approved lines and insufficient connections pose a hazard!
Gas connections may only be installed by qualified personnel!
Check for proper sealing of connections and ensure this during operation!
• Accessories must be clean and free of residue. Contaminants may reach
inside the combustion calorimeter and may cause false measurements
and/or damage.
• The input pressure for the gas connections must not exceed the
specifications of the technical data of the combustion calorimeter.
• Check each connection carefully for leaks. When leaks are present, the
system draws air and indicates false measured values.
• Do not use sealant for sealing the gas connections. Sealant components
may falsify the measurement result.
• Only suitable lines may be used.
6.3.3.1 Ignition protection gas supply – Compressed air
Compressed air is required as the ignition protection gas for operation of the
combustion calorimeter. Ensure sufficient supply and seal of the connections –
check connection point for proper seal.
Device requires compressed air at 4.5 – 5 bar, 16,000 – 30,000 l/h, for operation.
Air recommendation as per ISO 8573-1, class 533 (solid material: 40 μm (class
5)/dew point: –20°C (class 3)/oil quality: 1 mg/m³ (class 3))
• When installing a shut-off valve of the ignition protection gas supply
Post warning information: Warning – Valve of the ignition protection gas
supply – Follow instructions before closing!
