When someone says it can’t be done, they’ve obviously not spoken to us. So if anyone in the industry suggests that you are asking for the impossible, it will always be our privilege to prove them wrong yet again.

From start to finishBecause unlike most UK louvre companies, we design, detail, supply and install. So not only do our products match your requirements precisely in terms of function but also in style, finish and colour.

This determination to see things through to the finished result gives architects and designers a unique opportunity to create outstanding ventilation features or screening controls within the external cladding. And our can-do attitude makes those satisfied clients come back to us time and time again.

Past, present and future Since the early sixties this customer-first philosophy has been enshrined in all our activities. Blended with manufacturing experience and practical expertise honed over almost half a century, it has seen Naco define everything from metal and glass louvres, natural air and smoke ventilators to mist separators, sunscreens and brise soleil.

It even instigated a no-nonsense software program on our website to take the hassle out of sizing louvres and unscrambling such things as face, jet or core velocities and free areas.

An ideal environmentBut user friendliness isn’t the only challenge facing building design today. Increasingly environmental friendliness is nowa design pre-condition, reflecting a growing duty to protectthe natural environment whilst controlling our owninternal environments.

Learning to harness nature’s elements to our advantage rather than simply fighting against them is now driving forward our engineering and design teams more than ever. And their progress can be measured by the comprehensive rangeof Natural Air Ventilators featured here in our latestproduct portfolio.

Stack DrivenStack Effect(Chimney Effect)

This method does not rely so much on the wind, but more on the buoyancy affect created by the warmer air inside the building being less dense thanthe outside cooler air.

By the use of a roof terminal orhigh-level ventilators, the warmer stale air will rise up and exhaust through the high level ventilators, and this movement of air will draw in the outside air at low level.

The stack effect method is usually more reliable than the wind driven one.

Wind Effect

The wind blowing against the building (Windward) side creates a positive pressure on that sideof the building. This in turn creates a negative pressure on the opposite side (Leeward) side.

Through the correct positioning of ventilators to both sides of the building, often together with a roof terminal, airflow is produced flowing from the windward side towards the leeward side.

l Natural ventilation systems have now become the favoured approach to providing the ventilation solutions for schools, universities and low-rise buildings in general.

l Natural ventilation offers significant benefits over mechanical systems on these types of buildings.

l Significant cost savings, both on the initial installation cost and the ongoing service & maintenance costs are evident.

l Running costs are also significantly lower, with little or no power consumption required, depending on the type of system selected.

l Construction costs can also be reduced, whilst giving the architect more room for manoeuvre, as there is no longer any need to allow for plant rooms.

l Free night cooling is also readily available to reduce energy loads on the building.

l There is also evidence that natural ventilation systems offer health benefits to the building occupants, with cases of ‘Sick Building Syndrome’ becoming a thing of the past.

NaturalVentilationPrinciples

Mixed Mode (Hybrid System)

To allow building designers greater flexibility and to alleviate some of the vagaries that our weather can have on the efficient function of both the wind driven and stack systems, Ruskin can offer a mixed mode system, to compliment a totally natural system.

This can encompass a range of NAV ventilators fitted with heating coils, either with or without fan assistance andfan coil units.

Control systems would enable the motorised items in the hybrid system to only be called on when deemed necessary.

Mixed mode is particularly useful for winter heating and summer cooling applications when the natural system might struggle to provide the optimum room ventilation conditions.

Generic BuildingCross Section

Solar ShadingReduces the heat gain into buildings and therefore lowers the ventilation and energy requirements.

Nav UnitsProvide controlled naturalventilation and free night cooling. Optional tempering of the incoming air.

Transfer Grilles (G45)A convenient way to allow air to pass through internal partitions, towards the roof terminal zones.

Fan CoilsFan Coils have been chosen from the proven Actionair range and are based on the Hydropac eco friendly unit Model EC. Featuring low noise, low energy fans with minimal fan heat with full acoustic and thermal insulation.

Fan Floor SwirlsCan be considered for use in floor void situations. The fan will induce cool fresh air at low level and this will displace the warm stale air through the extract or transfer grilles.

Vengen Glass LouvresProvide controlled ventilation with high free areas and the added benefit of daylight.

Roof TerminalsProvide an efficient method of allowingthe warm stale air to escape. Also theyare used for allowing the entry of fresh outside air in wind driven applications.

The primary components of our Natural Ventilation range are the NAV units detailed on pages 8-13. However several more products from Ruskin Air Management Ltd are available that are perfectly suited to enhancing a natural ventilation scheme.

A number of these products are showcased on the building below and are described on page 17 under ‘Complimentary Products’.

Heating Coil Type 19Is a low - H20 heat exchanger which enables efficient output to be received at low flow temperatures. Tested to 20 bar. Working pressure 10 bar.

Pipework Connections1/2” BSP female connections can be of ‘Standard’ Type or ‘Alternative’ Type (see illustration)

1/2” BSP Drain Connection1/2” BSP Vent Connection

During times when the outside air movement is not favourable to a natural ventilation system, the Dynamic Fan System can assist to create passive ventilation of cool air in summer or increases the heat output from the heating coil to the occupied zone on colder days.

The Dynamic Fan System simply ‘snap’ fits over the heating coil and requires a 220V AC electrical supply locally to supply the 24v DC transformer supplied with the system.

Every set includes a control panel, control unit, power supply and instruction manual.

The panel is fitted with a water temperature sensor and a room temperature sensor both of which continue to operate the system in Automatic Mode simply by selecting a room temperature (the factory setting is position 6 that configurates to a value of 22°C).

Automatic: The spread of the fan will automatically modulate until desired temperature is reached with the fan speed dropping to a standstill at the set level.

Boost: Fan will run at maximum speed for 15 minutes before returning to automatic.

Passive Mode: TBC

During certain times of the year outside air may be too cold for direct entry into the building. Therefore a heating coil can temper the incoming air to allow the desired ventilation rates to take place.

Heating Coil Dynamic FanSystem

The inclusion of a heating coil allows extra flexibilityto your natural ventilation system.

Heat Output Against Flow Rate

E

The components of the DBE system are easily snapped onto the Low-H20 heat exchanger using tension springs. This causes no hydraulic changes in the heating installation, however you should take account of the increased output of the Low-H2O radiators when sizing the installation. Furthermore, only a single 220 VAC supply needs to be provided locally. This supply point can be located invisibly behind the casing. The power supply provided should not be used with a direct 12 VDC supply. For freestanding appliances the power supply is via the feet of the appliance.The number of DBE units per radiator depends on the length of the Low-H20 heat exchanger, with a maximum of 6 DBE units coupled up in series. The type of casing also has an effect

on the possible number of DBE units.

Connection 12 VDCTake into account the + and - when using your own power supply. If not, the Control unit will be damaged.

Programming own user profileWant to construct your own user profile? The DBE microprocessor board has a communica-tion port.The DBE system can be reconfigured via this port: water temperature, revs, duration of boost, etc, can be changed.This involves a modification of the standard parameters. In order to do this you need a PC with DBE communication software. The operation of the software is explained via a help function. A CD-ROM and connecting ca-ble are available, as well for RS 232 - as USB connection.Future upgrades of this communication soft-ware can be freely downloaded from the Jaga website.URL: http://www.jaga.be/drivers/JAGA_DBE_CUSTOMERS.zip

DBe_Installation

Adjustment and operationSet the maximum desired comfort temperatu-re using the multi-position switch on the mi-croprocessor board. Every position (from 0 to 9) corresponds to a maximum desired value. The board also has a table of these values. Position 6 is the standard factory setting. This corresponds to a value of 22°C (room tempe-rature).The system is now controlled fully automa-tically. The microprocessor measures the room temperature and the average water temperature in the Low-H20 heat exchanger. These measurements are processed and the microprocessor determines the correctly mo-dulated speed of the activator depending on the comfort temperature set. This means the activators will run faster if the temperature is significantly below the desired level. As the temperature rises, the speed drops, coming to a complete standstill when the desired temperature is reached. The system then operates completely statically. This automatic operation is the “comfort” mode.You can always demand extra heat by turning on the manual “boost” function. The system will then work at maximum power for the time set. The standard setting is 15 minutes. In or-der for the unit to operate, the water tempe-rature sensor must detect a minimum water temperature (flow) of 28°C.

Low- temperature heatingThe extremely high efficiency and power out-put at low temperatures, even on small radia-tors, make the DBE system an ideal candidate for low- temperature heating.

Natural Vent Control Panel Models VCP-01/ VCP-04 are especially designedfor use in separate rooms or small zones. Due to the large amount of Naco accessories various functions can be added, e.g. automatic weather, room temperature and indoor air quality (CO2) control. It is possible to connect several ventilation control panels in order to enable central switching, e.g. closing in case of wind or rain or time-controlled ventilation.

For situations that do not call for the features of the VCP Control Panel, the ventilation can be controlled by the following two methods.

MOTOR CONTROL: Via the vent open/ close switch

MANUAL CONTROL:Via lever handle
