1. HEAT EXCHANGER – WATER HEATER: 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 manifold (¾`` male thread) is situated in the upper part of the housing. An optimally selected water exchanger was adapted to work in
two positions: horizontally and vertically, with stub pipes facing upwards and downwards. 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 4 to 47 kW.
ELECTRIC HEATER: each electrical curtain consists of 6 electrical heaters of 670W to 2950W, depending on the size of the curtain. The heaters are connected into two sections of 2 and 4 kW
for a 1m curtain, 4 and 8 kW for a 1.5m curtain, and 6 and 9kW for a 2m curtain. The heating section is connected to form a 3x400V power supply star. There is a possibility of powering a 1m
curtain with 1x230V for a 2kW heater.
Thanks to such technical solutions and the application of a wall-mounted controller, the heater of each curtain can work in two heating programmes, e.g. for a MU-WING-10/6-R3 curtain - option
1): heating programme 1 - 2kW, heating programme 2 - 4kW, option 2): programme 1 - 4kW, programme 2 - 6kW, and analogously for the remaining curtain sizes. Change of programme is
possible from the controller HMI. The heating programme is independent from the fan speed setting.
2. CONTROL SYSTEM: it is equipped with an outlet on the connection clamp block X0 for MU-WING-W and on the X1 block for MU-WING-R3 for connecting an on-wall controller as well as
a valve actuator for MU-WING-W. MU-WING air curtains can be additionally equipped with a wall-mounted DX controller. The DX controller has a three-position heating switch. In the case of a
water curtain, to guarantee the proper functioning of the water valve, the heating switch must be set to position II (central) - otherwise the valve will not open.
The system of MU-WING-R3 is equipped with a safety device in the form of a fuse in the 230 V AC circuit.
3. HORIZONTAL FAN: the maximum temperature of operation is 95°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

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 curtain is energy saving and durable.
4. CASING: Made of metall material resistant to temperature up to 95°C.
5. INSTALLATION HANDLES: MU-WING 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 3 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 MU-WING 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 m.
IMPORTANT! Possibility of the vertical assembly applies only to the cold curtains and with water heater. Curtains with electric heaters may only be installed in a horizontal position.

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.
