PilotSupply air beam

FunctionFrenger’s supply air beam Pilot can be equipped with the following functions; cooling, heating and ventilation. Valves, controls, Regula, Secura, Regula Duo/Mono and Connect can be built into Pilot.

InstallationPilot I-60 is mounted as an integral part of the ceiling, where the beam is integrated into a standard 24mm exposed grid suspension system. Pilot is also suitable for installation in suspended ceilings with an 8mm shadow gap (Ecophon DG) between the ceiling panels.

Pilot X-60 is suitable for installation in suspended ceiling modules (600 x 600mm), such as metal ceilings.

FeaturesPilot uses a unique, patent-applied Jet gap that allows adjustable air flow, air pressure and spread of air. In all positions, the spread of air is fan-shaped, halving the air flow in the occupied zone compared with a straight spread of air. The cooling effects are measured using the Nordtest method NT WS 078, V-document 1996:1.

BenefitsThe Pilot I-60 represents the latest generation of active chilled beam technology, and as such offers the following benefits:

“Jet-Gap” design allows on-site adjustment of airdistribution and volume.

Beams can be adjusted on site to deliver more or less cooling & heating.

Induction ratio of up to 5:1 means high cooling capacity at low air volumes.

Pivoting underplate provides simple and quick access. Units are simple to clean and hygienic. Closed batteries are accessible for cleaning from 3 sides. Integrated easily with standard 24mm exposed grid ceilings on 600mm modules,

Numerous options for the orientation of air and waterconnections.

Quietest active chilled beam on the market. Provides an indoor climate in accordance with BE EN ISO7730.

FunctionOptional functionPilot is based on the induction principle. Ventilation air is released through a gap into a diverging zone, thereby creating a low static pressure. This low pressure results in the warm room air being drawn to the ventilation air through the batteries. The quantity of the warm room air is 4-5 times greater than the ventilation air. The air is cooled when it passes through the finned tube battery, which consists of aluminium fins with copper channels, through which chilled water passes. The heat of the room is taken in through the aluminium fins and transferred into the water circuit through the copper pipe and on to a central cooler.

The gap opening can be adjusted through different settings on four regulating screws. Changing the settings creates new air pressures and air flows. The air spread can also be adjusted so that different amounts of air can be obtained on both sides of the beam or an asymmetrical spread of air along one side of the beam. The technology is unique and a patent has been applied for, and we call it the jet gap technology. The gap opening is designed to guarantee the Coanda effect and the fan-shaped spread of air. The air’s adhesive capacity at the beam already occurs at the gap opening and the air then follows the beam out side to the ceiling by the Coanda effect.

ConstructionPilot is flexiblePilot is developed and designed for a high degree of flexibility. The flexibility consists of the simple variation of air distribution, air flow and air pressure for different situations. Pilot is a supply air beam that is compact in design yet nevertheless has optimal performance and maximal accessibility for cleaning and inspection. Where there are built-in valves and controls, these are also accessible for adjustment and maintenance from below.

Initial settings and adjustment of air spread, air flow and air pressure is simple, using four regulating screws.

One side of the underplate can simply be lowered using two cotter pins or completely dismantled by opening all four cotter pins. When the underplate is either lowered or dismantled, both the batteries are accessible from both the inlet and outlet sides.

Initial SettingsInitial adjustment simplePilot is a flexible product in which air spread, air flow and air pressure can simply be preset but also adjusted later to accommodate changes in the room. Initial settings and later adjustments are made by setting the four regulating screws in different positions. An allen key is used to adjust the regulating screws, and these can be adjusted even when the underplate is in position. The simple initial adjustment makes it possible to select a product early in the project and include the product in drawings, even through all input data is not yet available. In diagrams 1 and 3, lines are drawn to show the values that are obtained at different settings.

Example: A number of Pilot beams are installed in an open-plan office. When a separate office is to be included in the room, the amount of air and the air speed needs to be adjusted on the Pilot beam that is built into the new room in order to optimise the climate (see picture below).An allen key is used to close the two regulating screws that are closest to the new wall - three turns/regulating screws. Correspondingly, the two other regulating screws are opened with five turns/regulating screws. These adjustments have increased the total amount of air on this beam compared with before, and also changed the air speed. If the air flow is to be in a special direction, it is also possible to simply adjust to an asymmetrical spread of air.

For more information about Pilot’s initial settings, see the Frenger initial settings guide.

Different settings on the regulating screws create an asymmetrical spread of air

The regulating screws are adjusted with an allen key, and adjustment can even be made with the underplate in position

HygieneAll parts are accessible for serviceThe underplate to Pilot is simple to lower or dismantle. The underplate is fixed with four spring-loaded pins. If the two cotter pins on one of the long sides are opened, the underplate can hang on the two other pins. When the underplate is either hanging down or dismantled, both the batteries are accessible from below. The batteries are accessible on all three sides where air passes.

The air channel in the product can be cleaned or inspected via the inspection panel (ESHU125) at one of the product. The inspection panel is equipped with a handle.

When the underplate is either hanging down or dismantled, both the batteries are accessible from below.Insert: Cotter pins for attaching the underplate.

Additionally, removable access hatches can be supplied to ensure that the room air is not contaminated with dirty air from the ceiling void.

Pilot is supplied with Frenger intake pipes with standard sleeve size (ILF 125). The air connection is horizontal.For coupling alternative A (plus feature) the Frenger air connector (NPU-125) is included. For coupling alternative B (plus feature), Frenger’s elbow piece (BU90°) is included.

Connection A Connection B

Pipes

Pilot is supplied as standard with horizontal pipe outlets (ø12 mm). For coupling alternative 1 and 3 (plus feature) pre-assembled straight Tectite couplings and separately CU pipes are supplied, and for coupling alternative 2, and 4 (plus feature) pre-assembled angles couplings Tectite and separately CU pipes are supplied. The drawings include these products.

NB! When using compression couplings, support sleeves must be used because of the soft copper pipes! Max.temp. for Tectite is 65°C at 10 bar and 90°C at 6 bar.

Sound effect level LwoctFor calculating sound effect level

The sound effect levels Lwoct for each octave band in the beam are calculated by adding the correction Coct from the table above to the sound pressure level Lp dB(A).The sound pressure level is read from the dimensioning diagrams on pages 7 and 9.The sound effect levels are calculated using the following formula:Lwoct = Lp + Coct

Scatter diagrams, PilotThe jet gap technology in the Pilot beam guarantees the Coanda effect and the fan-shaped spread of air in all cases. The fan-shaped spread of air is halving the air flow in the living area compared with straight spread of air. Measurements shown are based on cooled supply air (Dt room air - supply air 5°C) and cooling in the water circuit (Dt room air - average water temperature 8,0°C). All heat supplied through the walls (according to the Nordtest method NT VVS 078, V -document 1996:1).

Please contact Frenger for more information on spread of air and different measurements taken.

OtherControlFrenger offers a controller which is very simple to use. To avoid heating and cooling being on simultaneously, the system is controlled in sequence, Regula Duo. Controlling exclusively heating or cooling also works very well, Regula Mono. Frenger’s internally developed condensation guard, Regula Secura, can also be mounted in the beam.See separate brochure for technical data, Regula
