The LEO EX water heater belongs to the category of special-purpose equipment. The unit is equipped with an explosion-proof fan, allowing it for installation in the potentially explosive area Z-2, in rooms with a hazard of explosion of gases, liquids and their vapours of explosion group IIB with T3 temperature class. The LEO EX water heater is a high-performance product that guarantees fast and efficient space heating. The technical and design features of the unit ensure safe and reliable operation, which is particularly important for use in potentially explosive rooms.
Basic parameters
| Power consumption | 6,1 - 57,3 kW |
|---|---|
| Air flow | 3600 m3/h |
| Mass | 34,5 kg |
| Casing | powder-painted steel |
The LEO EX unit is equipped with an ATEX-certified fan, enabling it to operate in facilities with explosive atmospheres.
The fan is placed in a specially shaped nozzle, which reduces airflow resistance, resulting in quieter operation.
When the heater is installed horizontally, under the ceiling, it is possible to direct the air in two directions to distribute the warm air over a larger area of the room.
Application
LEO EX, equipped with an explosion-proof fan, finds its use in facilities with special safety requirements, e.g. in heavy industry halls or welding plants.
