Fully plastic heater housing. With standard models in addition there are two special versions:

  • with IP66 protection class fan - ideal for high humidity premises such as car washes
  • with IP66 protection class fan and anticorrosive layer coated heat exchanger - ideal for aggressive environments, such as farms
Elegant buildings

Elegant buildings - a modern industrial design and aesthetic elements of the finish make the LEO FL heater fit for heating interiors of public buildings such as car showrooms, sports facilities, churches, exhibition rooms, etc.

Modern design

Modern design - the casing is made of anti-static ABS plastic; allowing the reduction of the overall weight of the device and making it look unconventional. The aesthetic finish of the heater is also due to the look of the stators made of anodized aluminium.

Savings

Savings - a low power consumption fan (280W) of a renowned manufacturer has been used. Its blades are made of specially shaped plastic, which reduces their weight and noise level during operation.

3D console

3D console - allows the heater to be mounted in parallel, at a 45° angle, in a horizontal or vertical position to the vertical and horizontal barriers, as well as to narrow pillars. It also allows the device to be turned around the connection point of the console.

M system

M system - is a modern, energy-saving control feature based on modulated fan operation (rotational velocity control of the fan in the temperature function). The speed of the fan and consequently, the heating power is adjusted to the current heat demand of the facility.

S Type control

S Type control - by use of an interior thermostat closes or opens the heating medium supply to the heat exchanger. To control efficiency of the fan a 5-stage control by use of rotational speed transformer controllers has been applied.
