Emergency Transportable Boiler Unit

Capacity:

600, 1200, 1800 kW

Fuel type:

diesel, LPG

The emergency transportable boiler unit ensures rapid heat supply to critical infrastructure facilities in the absence of the main heat source. It is mounted on a mobile chassis and can be quickly deployed on site.

Equipped with automation, remote monitoring, and safety systems. Mobility and autonomy make it an effective solution for emergency and backup heat supply.

natural gas, liquid fuel

Navi III 2800-5000

Capacity: 2800 to 5000 kW

NAVI III three-pass fire-tube hot water boilers with capacities from 2800 to 5000 kW operate on natural gas and liquid fuel. The design with a corrugated furnace and convective tube bundles ensures efficient heat transfer and high efficiency.

The boilers are equipped with turbulators, a modern control system, and full thermal insulation, ensuring stable, safe, and energy-efficient operation. Convenient access to internal components simplifies maintenance.

This solution is optimal for industrial and municipal facilities and can also be used as part of modular boiler units.

Implemented projects based on NAVI III

Boiler model:

three-pass fire-tube hot water boiler NAVI III 1800

Capacity:

1 800 kW

Fuel type:

diesel

Boiler house type:

Emergency Modular Boiler Unit (MBU)

The project was implemented with the support of the Belgian development agency Enabel in cooperation with a consortium of manufacturers BFBE ARDENZ and Eurotechenergo.

Based on the city's needs, 16 modular boiler units were delivered to the municipal heat supply company Kyivteploenergo. These units are capable of providing heat supply to socially critical facilities in the shortest possible time, including hospitals, kindergartens, schools, and resilience centers.
