LEO

Product catalog summary

Application
LEO fan heaters are designed for large volume buildings like industrial and public spaces. They function by heating air through a heat exchanger filled with hot water. The casing is made from expanded polypropylene (EPP), with options in powder-coated steel (ST) or austenitic stainless steel (INOX). These heaters are for indoor use where air dustiness is below 0.3 g/m3 and should not be used in corrosive environments or those containing oil mist. The heat exchanger can use water or a glycol solution up to 60%, and the medium should not corrode copper tubes.

Technical Data
The document details specifications for LEO heaters, including airflow rates, power supply, consumption, insulation class, acoustic levels, and operational ranges. For instance, the LEO S1 model has a maximum airflow of 2300 m3/h and consumes 120 W. The maximum heating water temperature is 120°C for standard models and 130°C for INOX/ST versions, with a maximum operating pressure of 1.6 MPa. These devices are suitable for indoor environments with a maximum working temperature of 60°C.

Installation
Installation instructions cover mounting brackets, assembly, and U-profiles. Proper installation is essential for efficient heater operation.

Connection Diagrams
Diagrams are provided for connecting heaters to the building's heating system, ensuring proper integration and functionality.

Start-Up and Operation
Guidelines for starting and operating the heaters ensure safe and efficient use, including checking connections, ensuring proper water flow, and monitoring performance.

Service and Warranty Terms
Details on servicing the heaters and warranty terms are provided to ensure long-term reliability and customer satisfaction.

Conformity with WEEE Directive 2012/19/UE
The heaters comply with the WEEE directive, concerning the disposal and recycling of electronic equipment.

LEO heaters make up a decentralised heating system. The air streaming through the heat exchanger filled with hot water is warmed up. Fan heaters are used for heating large volume buildings: general, industrial and public buildings etc. The casing of LEO heaters is made from extended polypropylene EPP. LEO in special version ST has a casing made from powder coated steel. The devices LEO in special version INOX have casing and air blades made of austenitic stainless steel. The devices are designed for indoor use where maximum air dustiness does not exceed 0,3 g/m3. Units are built using copper,...

De LEO-luchtverwarmers vormen een gedecentraliseerd verwarmingssysteem. De lucht stroomt langs de met heet water gevulde warmtewisselaar en wordt opgewarmd. Luchtverwarmers worden gebruikt voor het verwarmen van grote volumes in gebouwen: algemene, industriële en openbare gebouwen enzovoort. De units zijn ontworpen voor binnengebruik in een omgeving met een stofbelasting lager dan 0,3 g/m3. Отопительные аппараты LEO составляют децентрализованную систему отопления. Их работа основана на протекании горячей воды через теплообменник, который отдает тепло струе нагнетаемого воздуха. Предназначены...

Guidelines for System Connection ■ It is recommended to use flexible hoses on the water exchanger connections. ■ It is recommended to install vent valves at the highest point of the system. ■ The system should be executed so that, in the case of a failure, it is possible to disassemble the device. For this purpose it is best to use shut-off valves just by the device. ■ The system with the heating medium must be protected against an increase of the heating medium pressure above the permissible value (1.6 MPa). ■ While screwing exchanger to pipeline - connecting stubs has to be hold by wrench....
