1. WATER HEATER - HEAT EXCHANGER
: Maximum parameters of the heating agent for the heat exchanger are : 95°C, 1.6MPa. The aluminium and copper construction consists of copper
pipes of the coil and aluminium lamellae. The connection collectors (male thread ¾``) are located in the upper part of the casing. The optimum water exchanger has been adjusted to operate in
three positions: horizontal and vertical with pins going up or down. Appropriate lead of hydraulic connections makes it possible for the curtain to be assembled directly by the wall as close to the
door frame as possible. The air curtain with a water heater generates power from 8 to 28 kW.
ELECTRIC HEATER
: it consists of 1, 2 or 3 sets of heater elements in the amount depending on the option (length) of a particular curtain. Each set consists of three heaters generating in total
the power of 6 and 4,5 kW, powered with 400 V voltage, connected in a star. Due to such technical solutions the heater is capable of generating the rated power ranging from 6kW (for a 1m wide
curtain) to 13,5 kW (for a 2m wide curtain).
2. CONTROL SYSTEM:
it is equipped with an outlet on the connection clamp block X0 for DEFENDERA 100-200 WHN and on the X1 block for DEFENDERA 100-200 EHN for connecting an on-
wall controller as well as a valve actuator for DEFENDERA 100-200 WHN.
The system of DEFENDER EHN is equipped with a safety device in the form of a fuse in the 230 V AC circuit.
The algorithm of the system's operation anticipates the function of the fan's delayed switch-off lasting 30 seconds in order to cool the electric heater.
3. HORIZONTAL FAN:
the maximum temperature of operation is 90°C, the rated voltage is 230 V/50 Hz. The motor protection level is IP20, F insulation class. The horizontal fan applied in the
device with an advanced profile of blades and impeller geometry made of plastic makes it possible to obtain air capacities up to 5000 m
3
/h. The control of the electric motor as well as thermal
protections of the winding has been coupled with the control system which resulted in increasing safety of operation. Due to optimum power of the motor the DEFENDER curtain is energy saving
and durable.
4. CASING
: Made of high quality plastic material resistant to temperature up to 90°C.
5.
INSTALLATION HANDLES:
DEFENDER is characterized by simple, quick and aesthetic assembly that can be performed on a wall in both horizontal and vertical position. There are
from 2 to 4 installation handles attached (as an option) to the curtain (depending on the option (length). Connections of electric wires and water channels has been especially designed
not to interfere the general aesthetic values of the device. The name DEFENDER includes devices that are 1, 1.5 and 2 m long that, if necessary, can be additionally joined both
horizontally and vertically to achieve different air supply options: from the left to the right and the opposite. the reach of the air stream is up to 4.0 m.

3. ASSEMBLY
IMPORTANT!
● The place of assembly should be carefully selected, taking into account the occurring of potential loads or vibrations.
● Prior to all installation or maintenance work, disconnect power supply and secure it against unintentional reactivation.
● It is recommended to use filters in the hydraulic system. It is recommended to clean/rinse the system, draining a few litres of water, prior to the connecting of hydraulic conduits (the supply
conduits, in particular).
IMPORTANT!
The air is blown out of the curtain at high velocity, along the surface of the opening, thus creating a protective barrier. Air curtains should cover the entire width of the door opening, in order to
obtain the maximum performance of the curtain.
IT IS RECOMMENDED TO TAKE INTO ACCOUNT THE FOLLOWING PARAMETERS, WHEN ASSEMBLING THE CURTAIN:
The width of the door frame should be less or equal to the width of the supplied air stream, a single DEFENDER 100-200 100-200 unit – its door can be 1, 1.5 or 2m wide.
