7917 Emission Sampling System

Product catalog summary

Overview: The document describes an emission sampling system designed for direct sampling of high-temperature aerosols up to 500 °C (932 °F). It features a two-stage dilution system and is suitable for a wide range of applications including engine exhaust studies, burner characterization, and emission monitoring from domestic heating.

Specifications:

Temperature Range: Up to 500 °C (932 °F)
Pressure Range: ± 100 mbar vs ambient pressure
Power Supply: 230 VAC, 50 Hz or 115 VAC, 60 Hz
Dimensions and Weight: Sampling probe - 97 cm length, 5 cm diameter, approx. 2.5 kg; ESS Controller - 21 x 26 x 26 cm, approx. 10 kg; Complete system - approx. 21 kg

Features:

Direct sampling of hot gas emissions
Stable and reproducible dilution ratios
Stand-alone operation with integrated flow supply
Compatible with GRIMM SMPS+C and SMPS+E systems

Technical Data:

Dilution Air: Supplied by internal pump, filtered and dried
Dilution Air Flow Rate: 9 l/min for both stages
Flow Control: Temperature stabilized critical orifice
Sample Air Flow Rate: Variable, e.g., 0.3 l/min to 1.2 l/min
Sampling Probe Tip: Diameter of 8 mm (0.3 in)

Dilution Factors: The system offers variable two-stage dilution, with factors depending on the sample flow rate. For example, at 0.3 l/min, one stage provides a dilution factor of 1:31, and two stages provide 1:961.

Applications: The system is applicable for engine exhaust studies, burner characterization, stack measurements, emission monitoring from domestic heating, and combustion process optimization.
