The parts that keep water moving and the farm watched.
Pumps lift the water, drains carry the waste, and the control cabinet runs the equipment and raises alarms. Below: how we size them, what to monitor, and what to plan for when the power goes.

Three parts of the system.
Bottom drains
المضخات
Control cabinets
Sized on flow and head, with a spare.
The main pump sets the flow through every stage. We size it on design flow, pipe losses and lift, then add a standby so a pump failure does not stop the loop.

Alarms before the fish notice.
A RAS fails fast. A 2025 study of a RAS monitoring system notes that pump failure “can lead to rapid ammonia increase, oxygen depletion, and mass mortalities within a short period of time”, and that the delay between a fault and its detection is a main source of production risk. In that trial, a pump alarm sent when the pump stopped from overheating was credited with preventing fish losses ().Malandrakis, Sensors, 2025

Sensors chosen on species and risk.
Not every farm needs every sensor. These are the ones we discuss on every project.
الأكسجين المذاب
Falls fastest when a pump, blower or oxygen supply fails
Alarm; backup oxygen opens
Pump running / current
A stopped pump stops every stage after it
Alarm; standby pump starts
Water level
A drop means a leak, a blocked drain or a stopped pump
Local alarm; phone alarm on a large drop
درجة الحرارة
Sets oxygen demand and growth
Alarm outside the set band
درجة الحموضة
Drifts as nitrification uses alkalinity
Alarm; check dosing
Power supply
Everything stops without it
Alarm; generator start
Alarm set points are agreed with you per species. We do not use one fixed list for every farm.
What keeps fish alive until power returns.
A farm manager described a 5 a.m. power cut: blowers and pumps stopped, but fish were fine after 20 minutes because a backup diffuser in each tank switched on by itself. The primary generator would not start; the second one did ().Ebeling and Hightower, Global Aquaculture Advocate, 2010
Emergency oxygen
Cylinders behind a valve that opens when power fails, feeding a diffuser in each tank
Cylinder stock and a regular test
Air-pressure trigger
A pressure switch opens the oxygen valve if aeration stops, even with power on
Covered by the same test
Generator
Starts on power loss through a transfer switch
Fuel, maintenance and a second unit if one fails
Alarm dialer
Calls several numbers when an alarm trips
At least two people on the call list
Pumps and controls sized with the loop.
Pumps, valves and instruments come from specialist makers. We size them on the whole system and test them with it.
Sized on the loop
Flow, head and levels from your layout.
Standby designed in
Spare pumps and backup oxygen planned from the start.
Your power supply
220, 380 or 110 V, and your generator setup.
Fitted and tested
Supplied, fitted and tested with the system before it ships.
No. Pumps, valves and instruments are sourced from specialist makers. We size them, fit them and test them with the system.
It depends on species and risk. We agree the sensor list with you. Dissolved oxygen, pump status, water level and power are the usual starting point.
For the main circulation pump, yes, on almost every farm. A stopped pump stops every stage after it.
Tell us your backup power setup and we design the cabinet around it.
Yes. We plan a local alarm and a phone alert to more than one person.
That depends on backup. Plan emergency oxygen that opens on power loss, a generator, and an alarm that reaches someone who can respond.
Send the layout. We size the pumps and controls.
Tank layout, design flow and power supply are enough to start. A first layout and equipment list come back in 3 days.
