Belgium – Contamination-monitoring devices – R.O.K. AANKOOP EN ONDERHOUD ROOKGENERATOREN EN FOTOMETERS

The contract concerns the conclusion of a framework agreement (R.O.K.), with one participant per lot, and includes the following:

Lot 1 (Supply): Supply and maintenance:

- 4 units Lazkin nozzle aerosol generators

- 3 units Thermal aerosol generators

- 4 units Measuring instrument/photometers including printer

Lot 2 (Services): Includes the maintenance (preventive and curative) of the already present equipment listed in the table below.

Equipment Type Serial Number

Aerosol generator Lazkin nozzle TDA-4A 10381

Aerosol generator Lazkin nozzle TDA-5B 17708

Aerosol generator Lazkin nozzle TDA-5C 20389

Aerosol generator Lazkin nozzle TDA-4B 28614

Aerosol generator Lazkin nozzle TDA-4B 28616

Aerosol generator Lazkin nozzle 6D Thermisch 32487

Aerosol generator Lazkin nozzle 5D Thermisch 35596

Fotometer TDA-2G 15709

Fotometer TDA-2H 20442

Fotometer TDA-2I 35744

During the entire lifespan of the equipment, maintenance, both preventive and curative, and calibration must be provided. This is for both the already present equipment and the newly purchased equipment (both lots). The equipment to be purchased is needed to check the integrity of HEPA (High Efficiency Particulate Air) filters. These devices are often described as an integrity or aerosol test. With these devices, the functioning of the HEPA filters can be checked as well as the detection of possible leaks. A test aerosol is introduced into the air stream before the filter, after which a particle detector (photometer) is used to check if particles pass through the filter.
