Auto Replacement Equipment (ARI)

Uninterrupted power supply for critical situations

Automatic backup power supply systems (ARI) for homes, offices, and manufacturing facilities. Your lights, heating, and servers will continue to function even if the power grid goes down.

What to do if the power goes out?

Storms and network failures are becoming more frequent. For private homes, this means no heating (heat pumps and gas boilers do not work without electricity), no water, and darkness. For businesses, it means downtime and data loss. We install ARI (Automatic Reserve Switchover) systems that switch your facility to backup power in a matter of seconds without human intervention.

• Peace of mind You don't have to look for a flashlight or go outside in the rain to start the generator. The system does everything itself.

• Heating protection Modern heating equipment is sensitive. We provide stable voltage ("pure sine wave") to prevent damage.

• Business continuity Critical systems – servers, alarms, cash registers – continue to operate without interruption.

Diesel and Gasoline Generators We supply and install stationary generators with automatic start-up. From compact solutions for private homes (5-10kW) to high-power diesel generators for production facilities. We perform exhaust gas removal and sound insulation.

UPS and Battery Systems A solution for places where there cannot be even a second of interruption (e.g., server rooms, medical equipment). UPS devices ensure immediate switching and stable voltage while the generator is started or the network is restored.

ARI Automation (ATS) The "brain" of the system. This is a control cabinet that monitors the city network. As soon as the voltage disappears or becomes unstable, the automatic system disconnects the city input and gives the command to start the generator. When the network returns, the system automatically switches back and shuts down the generator.

How do we work?

1. Audit and Load Calculation We determine which appliances are critical (e.g., only heating and refrigerator or the entire house) and calculate the required generator capacity.

2. Location and Ventilation We choose a safe location for the generator. If it is located indoors, we design a forced ventilation and exhaust system.

3. Installation and Connection We integrate ARI automation into your main distribution cabinet and install power cables.

4. Testing We simulate a network failure to ensure that the system starts up and switches over correctly.

Frequently Asked Questions

How quickly is the power restored after an outage? With a generator, this usually takes 10–30 seconds (the time it takes for the engine to warm up and stabilize). With a UPS system or solar batteries, the switchover is instantaneous (0.02 seconds) – you won't even notice the lights flickering.

Can I use my old generator? For the automatic system to work, the generator must be equipped with an electric starter and a control input. Cheap generators with a "pull cord" are not suitable for the automatic system, but we can install a semi-automatic switch (reverse switch).

Which is better – diesel or gasoline? For short-term emergencies and low power requirements in private homes, gasoline is cheaper and quieter. For long-term operation and high power requirements (above 10 kW), a diesel generator is more reliable and economical.
