Fish farm automation technology
The entire process from farm specifications to the application of automation technologies
Why automate your aquaculture?
There is an outstanding number of reasons. Let’s get through the most important ones, that will be brought to you, even the smallest IFF configuration so your fish farm management can be better and have a remote control.
The electricity bill comes every month and energy consumption is usually one of the biggest expenses of running a farm. What if you can spare up to 40% of your power consumption by assuring, that your devices run only when it is actually needed?

IFF Controllers
The IFF Controller is a ready-to use PLC(PAC) unit, installation of which can be completed by a customer. It can handle reading from up to 4 probes of any combination and control up to 4 switches/relays. Easily mountable on a wall or even a mobile container.

Regardless you have a single fish tank or operating an international, corporate aquaculture chain, IFF Gates, which connects all technology equipment together, will create the backbone of your business.

IFF SwitchBox
Both single-phase (SB230) and three-phase (SB400) versions can be easily connected to the IFF Controller and allow you to control your devices, regardless of the given electro installation type.
Start your automation Product detailsHow it works
- Take a construction plan of your farm (or a drawing);
- Make marks for all measuring points and devices that you want to control;
- Add marks for IFF probes (measuring points), SwitchBoxes (switchboards), and Controllers (PLCs) with the wiring between them;
- Go on-site with a measuring device, validate all the cable lengths and measuring points anchoring details;
- Make sure that the cable laying will be appropriate, considering the toughness of walls/ceilings;
- If necessary, ask your electrician for an opinion.
Estimated time for this step 1-x hours depending on the size of your farm |
What do you need Farm construction plans (or a drawing) and a measuring device, preferably a laser rangefinder. |
Scalability and clustering
Up to 4 probes and 1 SwitchBox to a Controller, up to 10 Controllers to one Gate to fill up an „IFF Cluster“.
The IFF platform is designed as modular and there are no general size limitations. Your design may involve an unlimited amount of connected IFF Clusters, split into groups or merged into one.

A small facility, driven directly by the owner's own or a small community's needs. 1-4 tanks with up to 1 ton of annual production; Up to 8 measuring points / 2 IFF Controllers and one IFF Gate setup.

Designed for extra heavy duty in the most challenging conditions.

XB4-S O2
A submersible probe for measuring the amount of dissolved oxygen in water
This probe consists of a stainless-steel head with the option of a replaceable sensor (CAP), a body with integrated electronics and a durable cable. Optical oxygen probes are distinguished by their extremely long service-life with minimum calibration requirements. The silicone membrane means that XB4-S probes also have much higher reaction-capabilities than competitive probes with Teflon elements.
