Benefits of the Biscay
Function
• Biscay is a climate beam with integrated recirculated air
opening in the bottom. This makes it possible to design
suspended ceilings without having to give particular
consideration to air gaps.
• Biscay is available in variants for installations parallel to
or at right angles to the perimeter wall of the building.
• A number of predefined airflow variants are available
for managing both low air flows for high pressures and
high air flows for lower pressures.
• The aerodynamically designed outlets ensure the favourable coanda effect needed for preventing draught in
the occupied zone in rooms.
• Swegon’s ADC (Anti Draught Control) enables the user
to adjust his or her indoor climate without interfering
with preadjusted flows in the ventilation system.
• Biscay can be fitted with a width extension kit for
adjustment to suspended ceilings with modular dimensions greater than 600 mm.
• The face plate perforations can be designed in various
variants to match the style of other components installed in the ceiling.

Biscay
Biscay is a closed climate beam with two-way air
discharge, cooling and ventilation or cooling, heating and
ventilation.
Installation
Biscay is designed for use in most T-grid ceiling systems in
terms of length and width. To guarantee a correct fit into
T-grid ceiling systems, we recommend T profiled sections
with a width of 24 mm. See Figure 3.

Suspension:
The units are delivered with four mounted support brackets designed for suspending them by means of SYST MS
assembly pieces (must be ordered separately). The abovementioned assembly pieces are available with threaded
rods of varying length. 200 mm long threaded rods
should be ordered if the unit is installed in a close ceiling
void. See Figure 16.

Water-based heating, Variant -B
Biscay is available with a convective heating function. The
water coil has two separate circuits. One circuit is used for
the circulation of chilled water and the other is used for
the circulation of hot water.
Electric heating, Variant -X
In the variant for electric heating, one or two tubular
heating elements are installed in the pipes that otherwise
would be used for heating water. Swegon’s LUNA control
equipment (or control equipment of another make) can
be used for controlling the heating elements. If the LUNA
is used, you have to relocate a jumper inside the controller
and reprogram its heating output signal for controlling a
triac unit with pulse-width modulation. The triac unit in
turn supplies current to the tubular heating elements in
the Biscay with a regulated 230 V supply (Figure 6). For
particulars on how to wire the LUNA control system and
how to relocate the jumper (necessary), see our separate
product datasheet and the installation instructions available at: www.swegon.com.

230 V AC
If you use a control system of a different make, wire the
electrical connections to the screw terminal blocks in Biscay’s terminal box according to the table below.

Overheating protection
Figure 6. Installation, water-based cooling and electric heating
The Biscay with electric heating is equipped with two
thermal overheating protections. The protection, with
automatic reset, switches out the heating elements (the
zero conductor) when the temperature exceeds 60°C.
When the temperature has dropped to 50°C, the overheating protection closes the circuit again and reenergizes
the heating elements. If the temperature rises more after
the first overheating protection has tripped, the manual
overheating protection will switch off the voltage when
the temperature reaches 75 °C. The tripped overheating
protection can be reset by pushing a manual-reset button
situated above the perforated bottom plate, between the
coil and the end panel of the product, see Figure 5.
CE marking
The Biscay with electric heating is CE marked in accordance with applicable regulations. The CE Declaration of Conformity is available at Swegon’s website:

Width extension strip
In applications where a load-bearing framework having
larger modular dimensions than 600 mm is used, the unit
can be made wider by installing width extension strips.
Typical larger modular dimensions are 625, 650 or 675
mm. The width extension strips are normally fitted at the
factory however they can be ordered as separate parts if
required.

Asssembly piece
Assembly pieces are required for hanging the Biscay
units to desired height above the floor. The SYST MS is a
complete kit for this purpose. The kit consists of ceiling
mounting brackets, threaded rods, nuts and washers. The
threaded rods are available in various lengths selected on
the basis of how far down the unit is to be suspended.
Variants are also available for double rods including
thread locking devices for simpler height adjustment.
If double threaded rods and thread locking devices are
used, it is important to mount the assembly vertically to
prevent breaks in the thread locking devices which would
have a negative affect on load bearing capacity.

Capacities are measured in accordance with pr EN 1516:1
standard. The specified water capacities are reduced by
5% whenever ADC is used in the Biscay. This implies that
you have to multiply the specified water capacities by
0.95 to obtain the correct capacity. The supply air capacity is not affected by the ADC.

Change of airflow variant
An airflow variant with a higher airflow can be changed
to an airflow variant with a lower airflow by plugging
nozzle holes in the air duct. A symmetrical airflow variant
can also be changed to an asymmetrical airflow variant
and vice versa in this way. See the Plugging Guide, Table
3.
Pressure drop for the cooling circuit
The following formula for calculating the pressure drop in
the cooling circuit: Δpk = (qk /kpk)2 [kPa]
Δpk = pressure drop in cooling circuit (kPa)
qk = flow of cooling water (l/s), read from Diagram 1
kpk = pressure drop constant read from Tables 5 to 9.

that call for throttling by means of a type CRP commissioning damper, the required data can be read using Swegon’s
ProSelect sizing program.
Room attenuation = 4 dB
** For airflows >50l/s use two air connections, to minimise inlet losses.

Diagram 2. Correction factor, k, for cooling capacity, Pk
(W) as a function of cooling water flow qk (l/s). Different
water flows have a certain effect on the cooling capacity
depending on how turbulent the water flow is. By checking calculated water flow against Diagram 1, the capacity
indicated in Tables 5 – 9 may need to be slightly adjusted
up or down. Pcorrected (W) = Pk (table) x k (diagram 2a/2b)

Heating
Sizing guides, Tables 12 to 16.
Water-based heating
Biscay units are equipped with a coil containing two separate circuits. The first functions as a cooling circuit and
the second as a heating circuit. When hot water circulates
in the tube circuit, the recirculated air from the room is
heated up in the coil, is then mixed with the primary air
and is distributed to the room. The inlet flow temperature
of the heating water should be kept as low as possible to
minimise the temperature difference between the air at
ceiling level and at floor level. The temperature stratification in the room will be negligible if the inlet flow temperature is kept at 40°C or lower. If the inlet flow temperature is up to the recommended max temperature (60°C),
the stratification will be perceptible even if it normally is
within the prescribed range.
In the majority of cases, the system will heat the room air
to a satisfactory temperature. In order to achieve good
operating temperature, other factors must be taken into
account. The following factors are typical in this respect:
Window dimensions, the U factor of the windows, the
orientation of the room, the location of the occupants,
etc. The quality and dimensions of the windows are also
important with regard to possible cold down draughts.
The windows used now-a-days are usually so well insulated that cold down draughts do not arise. Cold down
draughts are especially likely to occur in the renovation of
old buildings if the planner decides to keep the existing
windows.
Recommendations for water-based heating
Max. permissible inlet flow temperature:
60°C
Min. permissible heating water flow:
0.013 l/s
Min. permissible nozzle pressure:
70 Pa
Electric heating
The Biscay variant with electric heating utilises electric
heating elements instead of hot water. The tubular heating elements, situated inside the heating water pipes of
the coil, heat the circulated air that passes through the
coil. The largest portion of the heat capacity is conveyed
to the room through forced convection. Only a small percentage consists of radiant heat.
The tables are arranged according to airflow variant.
Select the relevant table to suit your application on the
basis of airflow, nozzle pressure and capacity requirements. The following can be read in the sizing guide:
Table guide
1.Unit length (mm)
2.Primary airflow, ql (l/s)
3.Sound pressure level Lp(A) for open damper with one air
connection (dB(A))
4.Nozzle pressure, pin (Pa)
5.Water-based cooling capacity, P v (W)
6.Pressure drop constant, water, kpv
7. Pressure drop constant, air, kpl
CAUTION! The total heating capacity is the sum of the
air-based and water-based heating capacities. If the primary air temperature is lower than the room temperature,
it causes a negative impact on the total heating capacity.
Pressure drop for the heating water circuit
Use the following formula for calculating the pressure
drop in the heating water circuit: Δpv = (qv /kpv)2 [kPa]
Δpv = pressure drop in heating circuit (kPa)
qv = flow of heating water (l/s), read from Diagram 3
kpv = pressure drop constant read from Tables 12-16.
The Biscay with electric heating is available in two capacity variants. See Table 10.

The cooling/heating capacity of the primary air
The following formula can be used for calculating the
cooling/heating capacity of the primary air:
Pl = ql x 1.2 x ΔTl
Pl = cooling/heating capacity of the primary air (W)
ql = primary airflow (l/s)
ΔTl = temperature difference between the temperature of
the primary air and the room temperature (K)

Cooling example
An open-plan office is to be fitted out with 1300mm
ceiling modules. To enable total flexibility for the relocation of partition walls, planners have decided to install the
climate beams parallel to the perimeter wall in a continuous line. A load-bearing framework having a profile width
of 100 mm will separate each module. The profiles are
dismantleable to enable the simple installation of partition
walls. A typical two-module room having dimensions b x
d x h = 2.5 x 5.1 x 2.8 m will be created in the aforementioned open-plan room. The room has a total cooling load
of 90 W/m2 = 1145 W.
The desired supply air flow to the room has been fixed at
21 l/s.
The level of flow-generated sound must not exceed 30
dB(A).
Design room temperature, summer: 25°C.
Chilled water temperature: 14/16°C provides: DTk = 2 K;
DTmk = 10 K.
Heating example
The same two-module office used in the cooling calculation has a heating load of 60 W/m2. This produces a heating load per unit of (2.5 x 5.1 x 60) / 2 = 380 W. The airflow must be the same as during the summer, i.e. 10.5 l/s
per unit. The primary air temperature must be increased
to 20°C in the winter. Design room temperature, winter:
22°C. This produces: DTl = -2 K. Heating water temperature of 44/36 produces: DTv = 8 K; DTmv = 20 K.
Solution
Heating
The primary airflow of 10.5 l/s in combination with the
primary air temperature of 20°C produces a negative
impact on the heating capacity: 1.2 x 10.5 x 2 = 25 W.
The heating capacity requirement from the heating water
or electric heating elements per unit is thus increased
from 380 to 380 + 25 = 405 W.
Primary air temperature, 15°C, provides DTl = 10 K
Solution
Cooling
The supply air that maintains 15°C temperature produces
P l = 1.2 x 10 x 21 = 252 W in cooling capacity. Each
Biscay (one per module) must thus manage (1145 – 252) /
2 = 447 W.
From Table 5, we find that a 1192 mm long Biscay, in
airflow variant LS and for a primary airflow of 10.5 l/s
produces 475 W in cooling capacity which meets the
cooling load.
Cooling water
With a cooling capacity requirement of 447 W for cooling water, the necessary water flow can be obtained in
Diagram 1. A temperature increase of DTk = 2 K produces
a water flow of 0.053 l/s.
From Table 12, at DTmv =20 K and a primary airflow of
10.5 l/s we obtain: P v = 490 W, sufficient for managing
the heating load.
Heating water
With a heating requirement of 490 W per unit and DTv =
8 K, we can obtain the required water flow from Diagram
3: 0.015 l/s.
The pressure drop of the heating water is calculated on
the basis of a water flow of 0.015 l/s and pressure drop
constant kpv = 0.0307, which is taken from Table 12.
The pressure drop will then be: Dpv = (qv / kpv)2 = (0.015 /
0.0307)2 = 0.24 kPa.
Electric heating
The 405 W heating load can also be covered with the
Biscay electric heating variant X2 which generates 400 W
heating capacity.
In Diagram 2a, we can read that a water flow of 0.053
l/s will not produce a completely turbulent water flow. A
water flow of 0.053 l/s produces 98% rated capacity: Pk
= 475 · 0.98 · 466 W, sufficient for covering the cooling
load.
The pressure drop is calculated on the basis of a water
flow of 0.053 l/s and the pressure drop constant kpk =
0.0204, which is taken from Table 5. The pressure drop
will then be: Dpk = (qk / kpk)2 = (0.053 / 0.0204)2 = 6.8 kPa.
Noise level
In Table 1 we see that the sound level with an open
damper (or without a damper) is below 20 dB(A). Diagram 4 shows the throttling adjustment range for a CRPc
damper, size Ø125 mm.

Ordering Key
Biscay climate beam system for:
• Cooling and ventilation
• Cooling, heating (water) and ventilation
• Cooling, heating (electric) and ventilation
With provision for or including factory-fitted ADC.
The units are supplied painted in Swegon’s standard
shade of white, RAL 9010, gloss ratio 30 ±6%
Contractor demarcation
Swegon’s supply demarcation is at the connection points
for water (according to figures under: Dimensions – Subcontractor demarcation/connection point). At these connection points, the pipework contractor connects to plain
pipe ends, fills the system, bleeds it and tests the pressure
in the circuits. The ventilation contractor connects ducting
to the connection piece (sleeve). The electrical contractor
connects the wiring to terminal box. The units are delivered without assembly set. The assembly set and other
accessories must be ordered separately.
Ordering examples
Example 1:
One 2392 mm long, 592 mm wide Biscay designed for
a high airflow. Both the water and the air shall be connected horizontally. The unit shall contain the function
for heating with water. The unit shall be equipped with
Swegon’s factory-fitted ADC feature. Standard perforation patterns in the bottom section have been selected.
Designation:
Biscay 2392-12/12-OH-B-C
Example 2:
Biscay units shall be installed in a long continuous row
along a perimeter wall. The ceiling has 2400 mm modules
and each module shall contain one Biscay. Most of the
distributed air shall be discharged into the room toward
the corridor wall. The design airflow is relatively low.
Since the units shall be installed in a long row (end-toend), the water connections have to be vertical. Electric
heating requiring 500 W capacity has been selected for
heating. No ADC shall be installed at the factory. The
architect has chosen oblong perforations arranged in a
square pattern in the face plate.
