Catalogue maximum flow and listed water volume are comparison values. Final selection also depends on solids and feed loading, biological media, aeration and available hydraulic head. UV listings show watts per lamp × quantity; they are not the total electrical load or a validated disinfection dose.
Where Pro CRDF-100 fits
Application
A dedicated pump-fed series for projects comparing the Pro footprint and three-lamp UV arrangement with the standard pump-fed range. The Pro name is not a substitute for a verified hydraulic or UV duty.
Hydraulic fit
Pro CRDF-100 is listed at 100 m³/h with 2 inlet connection(s) of 90 mm and 3 outlet connection(s) of 110 mm. Match the pipework and actual filter flow to the installation drawing.
Biological duty
The catalogue lists 100 m³ water volume. Media type, fill volume, aeration and daily feeding must be assessed separately; water volume alone does not establish biological capacity.
Plan the installation
Allow for the Pro model’s own footprint and connection sizes rather than using the corresponding standard CRDF dimensions. Review feed-pump duty, return levels, drain routing, service access and electrical requirements before finalising the installation.
How the treatment stages work
A pump feeds the combined treatment unit. Drum screening and automatic washing handle retained solids, while the biological chambers provide the agreed media arrangement. The catalogue lists three UV lamps for each Pro model; treatment performance also depends on flow, water UV transmittance and the selected lamp system.
Screen
The 75-micron SS 316 screen separates particles it can retain from the water stream.
Wash
A level sensor triggers automatic washing; high-pressure nozzles direct retained material to the waste route.
Biological stage
The chamber arrangement supports the specified media and aeration system. Monitor water quality as the biological stage matures.

The Pro 100 model is 4300 mm long, compared with 4000 mm for CRDF-100. Its UV listing is 100 W × 3, compared with 100 W × 3. Compare the complete footprint, pipework and treatment duty before choosing between them.
Service access and maintenance
Inspect the drum screen, spray nozzles, level sensor, PP drive gear and waste drain. Check the biological chambers and aeration arrangement according to the operating instructions. Isolate electrical and UV equipment before servicing; follow the supplied lamp and sleeve maintenance schedule.
Pro CRDF-100 questions answered
What is the maximum flow listed for Pro CRDF-100?
The catalogue maximum-flow listing is 100 m³/h. Final operating duty must account for the 75-micron screen, solids loading and hydraulic conditions.
What are the dimensions of Pro CRDF-100?
The catalogue lists 4300 mm length, 1050 mm width and 1450 mm height. Allow additional space for service access and connected pipework.
What UV lamps are listed for Pro CRDF-100?
The listing is 3 lamp(s) at 100 W each. This is a lamp-power listing, not a validated UV dose or the total electrical consumption of the filter.
Does the combi filter replace biological design?
No. The biological media, aeration, feed loading and commissioning plan must suit the application. The catalogue water-volume figure is not a guaranteed ammonia-removal capacity.
How do I request a quotation?
