2. STRUCTURE, INTENDED USE, PRINCIPLE OF OPERATION
2.1. INTENDED USE
For the convenience of users as well as different types of installations in commercial and industrial facilities we have designed an air curtain in two different options and three sizes:
● a DEFENDER 100 WHN curtain 1.0m wide with a water heater (8-11 kW, 1880 m3/h)
● a DEFENDER 100 EHN curtain 1.0m wide with electric heaters (6 kW, 2150 m3/h)
● a DEFENDER 150 WHN curtain 1.5m wide with a water heater (13- 19,5 kW, 3570 m3/h)
● a DEFENDER 150 EHN curtain 1.5m wide with electric heaters (12 kW, 3500 m3/h)
● a DEFENDER 200 WHN curtain 2.0m wide with a water heater (19- 28 kW, 4890 m3/h)
● a DEFENDER 200 EHN curtain 2.0m wide with electric heaters (13,5 kW, 5000 m3/h)
The use of the DEFENDER 100-200 air curtain enables the leaving of the room door open, regardless of weather conditions, thus providing a protective barrier. The curtain also enables a
simultaneous keeping of the required heating comfort inside the room/facility. The modern design of the DEFENDER 100-200 air curtain is a result of its wide range of application. The places in which
it is possible to install the device include: malls, ofce buildings, supermarkets, cinema compleEHs, as well as shops, store-rooms, manufacturing facilities or warehouse rooms. Please notice that the
use of an air curtain not only provides a protective barrier, but also it is an additional heat source in the room. APPLICATION: warehouse rooms, warehouses, sports facilities,
supermarkets, religious buildings, hotels, clinics, pharmacies, hospitals, ofce buildings, manufacturing facilities. PRIMARY ADVANTAGES: protection of climatic conditions in the room,
reduction of heating/cooling costs, universal size, ability to work both in vertical and horizontal position; simple, quick and intuitive assembly.
2.2. PRINCIPLE OF OPERATION
DEFENDER 100-200 WHN - heating medium, for example hot heating water, returns heat through a heat exchanger with a wide heat-exchange surface, thus providing high heating output (8-
28 kW). A transverse fan (1120-5000 m3/h) sucks in the air in the room, and pumps it through the heat exchanger, back into the room. The jet of warm air is directed downstream at high velocity,
thus providing an air barrier.
DEFENDER 100-200 EHN - electric heaters (2000 and 1500W each) heat up, as a result of the owing of electric current, and return the heat to the air; the air is blown off through the fan, which
sucks in the air in the room. A jet of warm air is directed downstream at high velocity, thus providing an air barrier.

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 prole of blades and impeller geometry made of plastic makes it possible to obtain air capacities up to 5000 m3/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 lters 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.

It is forbidden to place, dispose of and store worn-out electric and electronic equipment, together with other waste. Dangerous compound contained in electronic
and electric equipment have a very adverse impact on plants, micro-organisms, and, most importantly, on humans, as they damage our central and peripheral
nervous system, as well as circulatory and internal system. Additionally, they cause serious allergic reactions. Worn-out equipment is to be delivered to a local
collection point for used electric equipment, which carries out a selective collection of waste.
REMEMBER!
The user of equipment intended for households, and which has been worn out, is obliged to transfer such equipment to a collecting unit that collects worn-out
electric and electronic equipment. The selective collecting and further processing of waste from households contributes to the protection of environment,
reduces the penetration of hazardous substances into the atmosphere and surface waters.

Disassembly of the machine must be carried out and/or supervised by qualied personnel with appropriate expert
knowledge.
Contact a certied waste disposal organization in your vicinity. Clarify what is expected in terms of the quality of
dismantling the machine and provision of the components.
Dismantle the machine using the general procedures commonly used in mechanical engineering.
WARNING
Machine parts can fall The machine is made up of heavy parts. These parts are liable to fall during dismantling. This can
result in death, serious injury, or material damage.
Follow the safety rules:
1. Disconnect all electrical connections.
2. Prevent reconnection.
3. Make sure that the equipment is at zero voltage.
4. Cover or isolate nearby components that are still live.
To energize the system, apply the measures in reverse order.
Components:
The machines consist for the most part of steel and various proportions of copper, aluminum and plastics (Impeller made
of SAN - styrene, acrylonitryle, construction material with 20% glass ber) and rubber-neoprene (seat of bearings/hub).
Metals are generally considered to be unlimitedly recyclable.
Sort the components for recycling according to whether they are:
Iron and steel, aluminum, non-ferrous metal, e.g. windings (the winding insulation is incinerated during copper recycling),
insulating materials, cables and wires, electronic waste (capacitor ect.), plastic parts (impeller, winding cover ect.),
rubber parts (neoprene). The same goes for cloths and cleaning substances which have been used while working on the
machine.
Dispose of the separated components according to local regulations or via a specialist disposal company.
