IMP KlimaSwirl diffusers, Variable swirl diffusers

Swirl diffusers are designed for air-conditioning of room with floor to ceiling heights from 2.6 to 4 m and temperature difference between supply and room air of +10K to -10K. Due to the rotary swirling motion of the air discharge, induction of room air occurs very quickly.

Variable diffusers are designed for rooms with changing thermal loads which require different conditioning (heating, cooling). They are suitable for rooms with floor to ceiling height of up to 10 m and recommended temperature difference between supply and room air +10K and -10K. Required conditioning is achieved by the means of manual or power driven blades adjusting.

Swirl and variable swirl diffusers are suitable both for comfort as well as industrial air- conditioning.

� Swirl diffusers

ApplicationSwirl diffusers are designed for air-conditi-oning of room with floor to ceiling heights from 2.6 to 4 m and temperature differen-ce between supply and room air of +10K to -10K. Due to the rotary swirling motion of the air discharge, induction of room air occurs very quickly. Swirl diffusers are sui-table both for comfort as well as industrial air- conditioning.

DescriptionSwirl diffusers consist of plenum box made of galvanised sheet steel and diffu-ser face. Diffuser face is made of sheet steel powder painted in RAL 9010 or any RAL colour upon customer’s request.

OD-8/TRAccording to the temperature profile, OD-8/TR automatically adjusts the inlet air flow. The swirl effect is used in the cooling mode, while the vertical air flow is in effect during heating. During transition periods, the diffuser automatically adjusts the optimum discharge angle which contributes to increased comfort level in the room.

� Variable swirl diffusers

ApplicationVariable diffusers are designed for rooms with changing thermal loads which require different conditioning (heating, cooling). They are suitable for rooms with floor to ceiling height of up to 10 m. and recommended temperature difference between supply and room air +10K and -10K. Required conditioning is achieved by the means of manual or power driven blades adjusting. Variable diffusers are suitable for both comfort and industrial conditioning.

DescriptionVariable diffusers consist of plenum box made of galvanised sheet steel and diffuser. Diffusers are made of sheet steel or sheet aluminium (OD-11) and powder painted in RAL 9010 or any RAL colour upon customer’s request.

OD-11V/TRAt OD-11V/TR diffuser, centrally adjusta-ble blades can be adjusted automatically with the thermostat regulation. Thermo-stat perceives temperature of the supply air and automatically adjusts the blades angle.

• Fixed grille• For air supply or exhaust• Recommended temperature difference

between supplied and internal air in the room is between – 10 to 0 K

• Low static pressure drop and low noise level

• Recommended installation height up to 4.5 m

• Diffuser plate should be lined with the ceiling in order to establish the ceiling effect

• Square and circular diffuser plate

Diffuser plate attachmentFor square diffusers, central fastening OD-5/K1 or fastening with four screws on the edges OD-5/K4 can be selected. For cir-cular diffusers, only the central fastening is provided. Diffusers are usually installed with the plenum box with side or top entry spigot. Plenum boxes with side or top inlet can be selected. If additional air flow regulation is required, the plenum box with the M volume control damper is recommended.

� Swirl diffuser with thermostatic regulation OD-8/TR

The OD-8/TR swirl diffuser regulation mechanism with thermostatic regulation automatically switches the diffuser on in the cooling mode at inlet air temperatures below 20 °C and in the heating mode at temperatures above 30 °C. Available in sizes 600/24, 625/24.

OperationThe swirl effect is used in the cooling mode, while all directional guides (rolls) have to be in the same position. In the he-ating mode, the regulation system rotates every second directional guide 90°, so two guides are oriented facing each other, which directs the air flows against each other. The gradients of the flows combi-ne and redirect the warm air vertically towards the floor.

Application• Suitable for cooling, heating and transition periods,• Effective operation across the wide range of air flows,• Installation into suspended ceilings.

Advantages• Higher outlet air velocity at the nozzle:

achieving a more intensive ceiling effect,• Achieving of higher throw distance in the

heating mode,• Lower static pressure drop,• Silent operation, • High induction.

Description• Large number of rotational nozzles allows for

variable and precise discharge direction,• Metal part of the diffuser plate is powder- coated

in RAL 9010 or according to customer specifications,• Square diffuser plate with the rectangular

nozzle layout – KK version,• Square diffuser plate with the circular nozzle layout –

KR version,• Circular diffuser plate with the circular nozzle layout –

RR version.

Features of a single nozzle• Aerodynamic shape,• Distinctive and discrete design.

ApplicationDiffuser is designed for air conditioning of rooms with floor to ceiling highs of 3 to 10 m and high induction requirements. It is suitable for large temperature difference between supply and room air.

DescriptionDiffuser is made of housing which has a diffusing funnel moun-ted at the bottom. The direction of the discharged air is altered via the separately adjustable blades. The shape of the diffuser’s inner part allows “Coanda” effect.Housing consists of sheet aluminium and blades of pickled sheet steel. Complete diffuser is powder painted in RAL 9010 or any colour upon customer’s request.

Individually adjustable blades OD-11Use of the individually adjustable blades is recommended when the ventilation system is designed for the specific mode of operation and the blades can be adjusted during the diffuser installation.

Variable swirl diffuser OD-11VVersion OD-11V has centrally adjustable blades. Blades can be manually adjustable or by the means of electric motor installed on the outer side of the diffuser or by thermostat regulation. Diffuser is capable of altering discharge direction.

Variable swirl diffuser with the thermostat regulation OD-11V/TROD-11V/TR diffuser has a basic implementation of OD-11V upgraded thermostatically controlled. Automatic continuous re-gulation operates as a function of the temperature of air flowing through the diffuser. With additional configuration before instal-lation to ensure optimum operation of the demands of comfort in the room.

Regulation with the OD-11V/…/RR handleRegulation with this handle enables manual blade angle adjust-ment if the diffuser placement allows acess to the handle. This type of regulation is suitable for buildings with a lower number of diffusers when the ventilation system is designed for both summer and winter operation.

� OD-11V with the ADT-2 thermostat with analogue output

DescriptionThe ADT-2 differential thermostat with continuous analogue output is a controller that, based on the duct air temperature and room temperature signals, automati-cally adjusts the angle of OD-11V blades as required. One ADT-2 can operate up to 10 OD-11V units.

OperationThe controller compares the selected temperature curve, which is set according to the OD-11V position, desired mode of operation, etc, with data received from temperature sensors located in the air supply duct and in the room. Taking into account the desired temperature differen-ce, the controller generates a continuous analogue 0-10V DC output signal, which is then transmitted to the OD-11V electric motor drive. Comparing the temperature, the controller automatically recognises the heating or cooling mode and sets the OD-11V accordingly. In the case the duct air temperature is higher than the room temperature, the controller switches the OD-11V to the heating mode, i.e. to the vertical supply of warm air into the room. In the case the duct air temperature is lower than the room temperature, the controller automatically infers that the system is in the room cooling mode and accordingly generates a signal to set the OD-11V to the cooling mode.

AdvantageApplying ADT-2, the need for manual swi-tching of a large number of OD-11V units to the proper operational mode is avoided, since the controller switches the units automatically. In this way, the efficiency of room air conditioning is enhanced as well.

OperationAt OD-11V/TR diffuser, centrally adjusta-ble blades can be adjusted automatically with the thermostat regulation. Thermo-stat perceives temperature of the supply air and automatically adjusts the blades angle. No additional power supply and controls are required, so no additional wiring installation is needed. Blade angle according to the supply air temperature is shown in the chart below. A hysteresis behavior of the thermostatic head in both cooling and heating mode is shown in the chart. After the tempera-ture is stabilized, angle of the blades is adjusted to the medium value in about 15 minutes.

SizeOD-11V/TR diffuser can be made in sizes 200, 250, 315, 400, 500, 630 and 800 (sizes 125 and 160 are not available).

Regulation of the initial and final blade angleOD-11V/TR allows the regulation of the initial and final blade angle.During the selection of appropriate diffuser for certain room conditions with the Klima ADE software package, exact angles are calculated according to the installation height of the diffuser, supplied air quantity and the temperature differen-ce between supplied and room temperatu-re. Calculation is based on air flow speed of 0.2 m/s in the living area. Initial blade angle is preadjusted with the special nut in the range between 30 and 50°. Automatic opening of the blades is initiated, when the temperature reaches limit value, shown in the chart according to the preadjusted angle and number of used spacers. When initial angle of 45° is preadjusted without additional spacers and final angle is 75°, blade opening temperature is between 22.5 and 23 °C (designation 1 in diagram). Final blade angle is adjusted by adding spacers below thermostatic head. Default preassembled spacer allow complete opening of the blades until 75°. By each added spacer, final angle is reduced for 5°.Adding of spacers also change the ther-mostatic head characteristics (average values according to the number of added spacers are shown in the chart).

� Active VAV diffuser OD-14

• Supply air unit for ceiling mounting in active and non-active version.

• Standard color is white RAL 9010 – 30 % gloss, other RAL colors on request.

• Supply (active) and exhaust (non-acti-ve) version.

• Nominal sizes from 160 – 250.• Stable supply air throw length over a

wide supply air temperature range – active version.

• Available with plenum with air flow adjustment and measuring device.

• Air flows from 40 to 700 m³/h.Active diffuser version comes standard equipped with the Belimo LH24A-MP100 actuator. Diffuser is made of steel (all parts) and powder coated in RAL 9010 – may be painted in any RAL colour on request.

Function (Active version)The OD-14 is an active ceiling diffuser for supply air. Air is supplied to the room mainly through side slots, and this causes induction through the horizontal holes. The diffuser maintains high outlet velocity, not depending on air flow, and that means larger throw distances over the whole air flow range. The diffuser creates comfor-table conditions and no draught in an occupied zone.An external room controller varies the room air flow rate by changing the position of diffusers hat driven by the Belimo actu-ator with a standard 2-10V control signal.

Function (Non active version) Non-active versions are mostly used for extracting air. They can, however, be used for supplying air, but without any regulati-on of air flow.

ServicingRemove the perforated diffuser plate, and then turn the movable hat left a few times, in order to remove it (not possible with non-active versions). If you want to remove the diffuser, you must first remove the perforated diffuser plate, then remove the hat, remove the motor by loosening the actuator screws, and then loosen the screws which are holding the diffuser. Clean the parts with a dry cloth. However, if you have removed the actuator, you can also use a damp cloth.

InstallationOD-14 shall be installed with plenum, and the spigot should at least 3D upstream of the plenum, in order to ensure a reliable air flow measuring. Safety wire for the bottom plate comes as standard equipment, and prevents eventu-al falling of the plate in critical situations. OD-14 is electrically connected to a ready--to-connect cable plug. The cable can be removed from the actuator by a special Belimo system.Check that the actuator settings cor-respond to the factory settings – the direction switch must be set in position 0. When the supply voltage is switched on for the first time, i.e. at commissioning or after pressing the » gear disengagement« switch, the actuator travels to the home position (see table below).

CommissioningMake sure that the direction setting but-ton on the actuator is in position 0. Then, fully open the hat (via the 10V input signal or by hand pressing the clutch). Check the duct pressure is at the intended level. If not, check the system (fan, damper).

AdjustmentThe diffuser air flow rate is measured and adjusted using a damper in the spigot of the plenum. Air flow rate is calculated using the pressure difference and K1 factor.

Notes:- Connection via safety isolating transformer !- Other actuators can be connected in parallel. Please note the performance data !

Note (power supply voltage):- A device that disconnects the pole conductors (minimum contact gap 3 mm) is required for isolation from power supply.

OD-17 with actuator BELIMO LH24A-MP100

Direction of stroke switch• Position is set from factory and must

be set on 0.• When the supply voltage is switched on

for the first time, i.e. at commissioning or after pressing the »gear disengagement« switch, the actuator travels to the home position showed in table (home position).

Electrical installation• Connection via safety isolating trans-

former!• Other actuators can be connected in pa-

rallel. Please note the performance data!• Note, main power supply voltage: a devi-

ce that disconnects the pole conductors (minimum contact gap 3 mm) is requi-red for isolation from power supply.

Adaptation of operating range• Adjustment of the operating range

and measuring signal U to match the mechanical stroke adjustment is set automatically whenever the supply vol-tage is switched on, manual triggered by pressing >>Adaption<< button or with the PC-tool.

� Variable diffuser KD-8

ApplicationVariable diffuser KD-8 is designed for air supply in large rooms (sport halls, swimming pools, airports …), because of their large air handling capacity. Conti-nuously adjustable blades (up to 90°) in the diffuser plate allow the supply of both warm and cold air in different directi-ons i.e. horizontal, or in swirling motion towards floor.

DescriptionVariable diffuser KD-8 consists of plenum box made of galvanised sheet steel and diffuser plate. Frame and adjustable blades consist of aluminium sections – anodised to natural aluminium colour. Volume control damper made of perfora-ted sheet steel is mounted in entry spigot. Control blades are fastened together and can be adjusted from the central point.
