LEO FL fan heatersDescription of the unitControl system
Description of the unit
Fan heater designed for indoor installation. Modern design of its casing makes possible to apply it in representative buildings with increased level of aesthetics like car showrooms, exhibition halls, sports facilities etc.



Advantages:

- modern appearance of the casing made of durable ABS plastic
- rotary 3D console, which enables to install the unit parallel or at the 45o angle to the wall
- two types of units available:
  • M type – unit equipped with energy-efficient fan with electronically commutated EC motor. More information in Control System tab. ·
  • V type – unit equipped with standard fan with AC motor.

Modulated System


PRINCIPLE OF OPERATION
Adjustment is based on the heater efficiency change depending on the temperature. Operation of the unit is controlled by 0-10V control panels (VNT20 or VNTLCD), which automatically adapt its heating output to the changing conditions in the room. Controller smoothly changes the efficiency of the fan in the range 0-100% depending on the difference between set temperature and measured temperature.

FEATURES AND FUNCTIONS
  • Very low system inertia
  • Smooth regulation of the fan efficiency
  • Weekly programmer
  • Possibility of connection external temperature sensors
  • Different operation modes available:
    • AUTO/MANUAL - automatic or manual adjustment of the unit;
    • CONTINOUS/INTERMITTENT - shut down of the unit when set temperature is achieved or continuous ventilation of the room without heating function;
    • SUMMER / WINTER / VENTILATION – heating operation, cooling operation or operation independently of the thermostat.
BENEFITS
  • Better thermal comfort due to precise maintaining the set temperature.
  • Reduction of the noise due to operation with the lowest possible fan speed.
  • Possibility of control up to 10 units by one control panel (using R10 splitter).

ELiS R air curtainsDescription of the unitControl system
Description of the unit
Air curtains ensure thermal protection of room. They generate air barrier on entire door opening plane. It prevents the inflow of cold air during the winter and the inflow of warm air into the air-conditioned rooms during the summer.
Advantages:

- modern design of the unit enables to install it in buildings with high level of aesthetics

- adjustable outlet makes possible to set a suitable angle of air flow in door opening plane

- silent operation of the fans

- available in three versions: with water heat exchanger, with electric heaters and “cold” curtain without heating elements

- water heat exchanger consist of aluminium fins mounted on copper tubes

- DRV control system, which enables to connect the unit to the intelligent building management system BMS
More information in “Control Systems” overlap.



DRV control system

Starting of the air curtain occurs when the door is opened, just after transmitting the signal from a door contact (or thermostat) to the control system. Thanks to 3-step fans it is possible to set the efficiency of the unit. Setting a speed on a TS fan speed regulator with thermostat it is possible to adjust the air stream to the conditions in the door opening. For curtains with water heat exchanger the control system enables to control two or three-way valve. Through communication with the BMS is possible to operate with other systems in the building.



Features
- 3-step regulation of air flow stream speed,

-
possibility to chain the curtains by the wire with RJ plugs,

- advanced operation programs depending on selected master control signal,

- control system can be connected to the intelligent building management system (BMS). This solution enables to save and load the operation parameters of the unit, e.g. fan speed.
