GENERAL CHARACTERISTIC Heating capacity (kW) Air flow (m³/h) Weight (kg) Colour Casing AGRO 16 –45 1900-3700 34,6 – 36,9 grey powder-painted steel LEO AGRO water heaters are designed to operate indoors. They are used to heating rooms with medium and big cubic measure, where air is contaminated with solid particles. Materials used in LEO AGRO are corrosive environment resistant, so it can be installed e.g. in livestock buildings.

HEAT EXCHANGER Aluminium-copper heat exchanger is covered with a protective coating. It ensures high heating capacity and it is resistant to corrosives. DURABILITY The fan has been matched so that the rising resistance because of air contamination does not affect its nominal operating parameters. Large gaps between lamellas on the heat exchanger prevents against obstructing by solid particles. CLEANING LEO AGRO has thicker lamellas on the heat exchanger and fan with high protection degree IP66. It makes possible to clean the unit with water under the pressure or compressed air without fear of damage....

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 3000 2500 Horizontal range of isothermal stream (at velocity boundary equal to 0,5 m/s).

VERTICAL RANGE OF AIR STREAM Vertical range of nonisothermal stream (at velocity boundary equal to 0,5 m/s).

INSTALLATION BRACKETS Installation brackets enable easy and quick installation of the unit. They ensure optimal air flow around the unit. There are two types of the brackets available: • standard - they enable to install the unit on the wall and under the ceiling. • expandable - they enable to install the unit on the wall. They ensure distance regulation between the wall and the unit. It makes possible to clean it without dismounting. EXPANDABLE INSTALLATION BRACKETS INSTALLATION BRACKETS ROTARY INSTALLATION CONSOLE Installation console enables to rotate the unit by an 180° angle. It ensures...

INSTALLATION OPTIONS Steady air circulation should be provided in the entire room. Air blades should direct the air according to object demands. 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 SYSTEM SRV2d two-way valve with actuator R55 room thermostat with high protection degree 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. Air flow is regulated by the transformer speed regulator. It is most commonly used in objects, where independent and simply regulation of every single unit is needed. FEATURES: Low thermal inertia. Low investment costs. Easy to use. Independent regulation of every single unit. Gradual regulation of air flow....
