Barn ventilation is run by a thermostat
What happens. Fans and inlets follow a thermostat and a few set curves. They react when the temperature has already moved, and they do not know about humidity, the animals’ heat output or tomorrow’s weather.
What it costs. Heat stress, damp and poor air in the barn harm animal health and growth. At the same time fans run harder than needed, with a power cost that adds up through the year.
Why the usual fix fails. A thermostat with more stages or a bigger fan does not solve the delay. Correcting settings from the farmer’s feeling depends on who is on site.
How a fixed-price remote diagnosis checks it. From barn temperature, humidity, fan and inlet logs and the weather I check how a predictive climate control would have held the barn in range. The fixed-price remote diagnosis answers whether such control brings better climate and lower fan energy in your barns and what sensors it needs.

Feeding robots work from fixed feeding tables
What happens. Feeding and milking robots serve each animal from a table of amounts that is set per group. Individual animals differ in appetite, milk yield and health, and the table does not follow.
What it costs. Feed cost is the largest running cost of many farms. Too much goes to animals that do not need it, and too little to those who do.
Why the usual fix fails. Adjusting the table for each animal needs time that the farmer does not have. Many robots only repeat the stored plan.
How a fixed-price remote diagnosis checks it. From the robots’ records of feed amounts, milk yield and visits I check how much feed an animal-specific plan could have saved and what the data supports. The fixed-price remote diagnosis shows whether optimised feeding per animal is realistic with the data your system already stores.
Exhaust air scrubbers for pig barns must be run and proven
What happens. Large pig barns are required to treat their exhaust air, with a deadline for existing barns, and barns just below that size face ammonia reduction requirements (topagrar). Where scrubbers are fitted, they use acid, water and power.
What it costs. The scrubber’s running costs: acid, water, power for the fans and wastewater. Beyond that, the operator must prove that it cuts emissions as promised.
Why the usual fix fails. A scrubber running on fixed settings uses too much acid and water on days with low load and too little when the load peaks. Proving efficiency by spot measurements covers a few days.
How a fixed-price remote diagnosis checks it. From pH, recirculation, fan and dosing logs I check how the ammonia load of the exhaust air can be computed and the scrubber run to that. The fixed-price remote diagnosis shows whether control by computed load saves chemicals and gives a record of performance.
