The TECH EU-81 zPID HG is a microprocessor-controlled boiler control system with PID control, specifically for wood gasification boilers. It controls the fan, heating and hot water pump and optimizes the combustion process via an additional exhaust gas sensor.

Highlights/Advantages

⭐ Specifically designed for wood gasification boilers
⭐ PID control with additional exhaust gas sensor
⭐ Constant boiler temperature and stable operation
⭐ Reduced emissions through optimized combustion
⭐ Control of fan, heating and hot water pump

Detailed description

Area of ​​application & Target audience

The EU-81 zPID HG is exclusively for use with wood gasification boilers It is designed for use in residential heating systems as well as in technical applications where precise temperature and combustion control is required.

Everyday benefits

Thanks to the PID control with exhaust gas sensor, combustion is continuously monitored and adjusted. Temperature fluctuations are minimized, and the boiler operates more quietly and efficiently. This increases user comfort and ensures consistent heating operation.

Technology & equipment

The control system regulates:

the supply air (fan),

the heating circulation pump,

the hot water pump (boiler).

Additionally, an exhaust gas sensor continuously monitors the exhaust gas temperature. If the temperature rises, the fan speed is automatically reduced or switched off to prevent overheating.

Efficiency & Environment

Controlled combustion ensures consistent heat generation and can reduce fuel consumption. At the same time, emissions of dust particles and gases are reduced because the heat energy of the exhaust gases is utilized more efficiently.

compatibility & System integration

The EU-81 zPID HG is designed for classic hydraulic heating systems with wood gasification boilers. Various operating modes, such as heating mode, parallel pumping, summer mode, or hot water priority, allow for flexible adaptation to the system.
