vue sur des circuits PM avec bassins en zone d'expérimentation

vue sur des circuits PM avec bassins en zone d'expérimentation


9 independent circuits (PM1 to PM9)

9 Mixed pathogens (4 PMs from 2 to 4 tanks (200L) and 5 PM from 6 to 12 aquariums (15L)), circuits that can be used in recycling or Lost Water (EP)

- PM 1, 2 and 3 with 4 basins

- PM 4 with 2 basins

- PM 5 to 7 with 12 aquariums

- PM 8 and 9 with 6 aquariums

Technical description

Thermally regulated closed circuit with temperature control. Temperature range: 5-20 ° C. Cooling system via plate exchanger (brine).

Temperature, O2, pressure .. under supervision via a software of supervision (Centralized Technical Management)

Water treatment

Dechlorinated city water via activated charcoal filter

Available Flow


According to the circuit, from 1 000 to 4 000 l / h (visualizable with flow meter of the installations). This parameter is manually controlled. (Recycling pump with a theoretical maximum output capacity of 25m3 / h) managed by a variable speed drive


Regulated temperature (5-20 ° C)


Instructions: The oxygen level is maintained above 7 mg / l.

Possible oxygen supplies via a U-tube and / or individual air diffusers in each basin


Adjustable lighting ranges (on programmed clocks) with progressive lighting and extinction for the entire "trypanos pathogens" experimental room housing all independent circuits.
