GENERAL CHARACTERISTIC Heating capacity (kW) Air flow (m³/h) Weight (kg) Colour Casing LEO FL fan heaters are designed to operate indoors. They are used to heating rooms with a big cubic measure. Modern design makes possible to install them in representative rooms like car salons, sports facilities, churches, exhibition halls etc. There are two types available: Fan heater with energy-efficient EC fan, controlled by external 0-10V voltage signal, which enables fan speed regulation in 0-100% range (VNTLCD and VNT20 control panels); Fan heater with standard fan. Fan efficiency can be...

CASING It is made of heavy-duty plastic - ABS. It is resistant to corrosion and many chemicals. This item is fully recyclable. 3D ROTARY CONSOLE It ensures easy and aesthetic installation. FL unit can be installed in any position and in any place: on posts, walls and also under the ceiling. FAN Air flow is ensured by energy-efficient fan. Fan rotor is made of plastic, which reduces the weight of the unit. Special shape of the fan blades ensures silent operation. AIR OUTLET Outlet of air is equipped with manually adjustable air blades. They enable directing the air stream according to the...

40 Air temperature rise at unit’s maximum air flow. Inlet air temperature 0°C. Tw1/Tw2 - inlet/outlet water temperature. Horizontal range of air stream Horizontal range of isothermal stream (at velocity boundary is equal to 0,5 m/s).

Vertical range of air stream Vertical range of non-isothermal stream (at velocity boundary is equal to 0,5 m/s).

For LEO FL heaters there is specially designed console. It makes possible to install the unit on vertical or horizontal surfaces, posts etc. There is also the possibility to install the unit vertically, horizontally or at the 45° angle to the surface. Installation console enables unit rotation around one of its axis. vertical installation horizontal installation using the console vertical installation using the console installation under the ceiling * for air blades installed vertically.

INSTALLATION OPTIONS Steady air circulation should be provided in the entire room. Correctly installed heaters should direct the air to the occupied zone. Heaters installed on the opposite walls should be overlapped. Air flow stream shouldn’t be limited. Heaters installed in the corners should direct the air to the center of the room. Air inlet shouldn’t be limited.

CONTROL SYSTEMS VNT20 control panel with built-in room thermostat SRV2d two-way valve with actuator VNTLCD speed regulator and thermostat with weekly programmer and display SRV3d three-way valve with actuator System M is energy-efficient heating system prepared for buildings with medium and big cubic measure. Airflow and therefore heating capacity are automatically controlled depending on actual temperature - air flow is a response to the current heat demand. Control panel (VNTLCD or VNT20) automatically and stepless change the speed of the fan according to difference between air...

RD programmable room thermostat SRV2d two-way valve with actuator AC SRV3d three-way valve with actuator It is the simplest ON/OFF regulation system. Fan heater is controlled by room thermostat, which turns on the unit (or/and open the valve) when measured temperature drops below set temperature. Fan air flow is regulated by transformer speed regulator. It is commonly used in objects, where independent and simply regulation is needed. TR/TRd fan speed regulator FEATURES: Low thermal inertia. Low investment costs. Easy to use. Independent regulation of every single unit. Gradual regulation...
