Heating

Helios – wall heaters  

helios


Basic features

 - Air flow up to 5700m3/h
 - Motor protection IP 44
 - Wall or ceiling instalation
 - Water temperature up to 130°C 

Usage

HELIOS heaters  are designed to be integrated in heating system in industrial buildings, sport facilities… 
HELIOS heaters  are designed for indoor operation for conveying fresh air free of rough dust, grease, chemical fumes and other impurities.

Installation and assembly

RL fans are designed to be integrated in internal heating system. 
 Allowed temperature range in environment (place of installation) is from 0 °C up to +35 °C, relative humidity up to 90%.

Outdoor applications are not possible All non-standard features of transported air must be discussed and confirmed by producer or authorized dealer.
 In any case installation it must be done so that there is enough space for access in terminal box and fan motor cup.  If the risk of moisture condensation inside the fan exists, it is better no situate motor (the fan's cup) downwards.

To not increase pressure lost and noise we dont recommend install any acessories on unit air inlet or outlet .

Construction and materials

Unit bodyes and impellers are made from steel and painted with epoxyd color. Motors are made of aluminium alloys, copper and plastics. All materials are designed in acordance with fan usage, maximum durability and minimal maitenance.

Impellers

Impeller blades has optimized shape for maximal air transport efficiency and minimal aerodynamic noise  Impellers are perfectly statically and dynamically balanced. Proper direction of the impeller rotation must be checked after instalation and connection on power suply. Correct direction of rotation is marked on fan body.

Motors

AX  fans are equiped with energy saving single-phase and three-phase asynchronous motors with an external rotor and a resistance armature. The motors are situated inside the impeller and during operation are optimally cooled by the flowing air. The motors have high quality enclosed ball bearings with permanent lubricating filling enable the fans to reach above 30,000 operating hours without maintenance. 
The motor electric protection is IP 44 and insulation class is B. The motor windings are impregnated to provide them with additional protection against moisture.
For motor protection (overheating) are used thermal contacts situated in the motor winding. The thermo-contacts are miniature bimetal switches which after being connected to the protective contactor circuit protect the motor against overheating (damage) due to any reason. In case over heating fan automaticaly stop. After fan cool down is starts automaticaly.

Water heater

Coil tubes are made from copper, fins are made from aluminum.  Collectors are made from copper. Nr. of rows is 2. Coils are equiped with air and water valve. Coils are pressure tested on 1,6MPa. Maximum working temperature is 130°C.

Electrical Equipment

Terminal box is placed on fan body and has protection degree IP 54. Motors are equipped with a starting capacitor which is placed on the fan body too. For wiring diagrams, see detailed information in technical catalogue.

Control

The output of all HELIOS fans can be fully controlled by changing the speed. The fan's speed is changed depending on the voltage at the motor terminals.

More stage voltage control (transformer) is the most suitable, technically as well as operationally. There is no interference, humming, squeaking or vibration of the motor. For suitable type of controller see detailed information for each unit type in tecnhical catalogue.
