CWW
Circular duct heaters for hot water
The CWW with circular duct connections uses hot water as the energy carrier and is used for heating the
ventilation air in a ventilation system. The CWW can also be used for heating individual rooms or zones.
For controlling the room or supply air temperature, the duct heater is supplemented with regulators, sensors,
actuators, valves and anti-freeze protection.
CWW
• 15 standard sizes
• Circular duct connection with rubber seal
• Casing of Aluzinc-coated sheet steel, AZ 185
• Openable cover for inspection and cleaning
• Hot water coil with 2 or 3 tube rows
• Air tightness class C to EN 15727
Design
The casing is made of Aluzinc-coated sheet steel, AZ 185.
The coil has copper tubes and tube connections, and aluminium fins. An openable cover simplifies inspection and
cleaning. The duct connections are provided with rubber
seals. The duct heater conforms to air tightness class C to
EN 15727.
Operating data
Max. operating temperature:+150°C
Max. operating pressure:
1,0 MPa (10 bar)
The coils are pressure tested and tested for leakage.
Capacity
Air tightness class C
Examples of capacity for each size are given on pages 4 to
11. You can also do your own calculations using our webbased VEAB Select calculation program (www.veab.com),
or get in touch with our sales technicians for assistance.
The CWW duct heater conforms to air tightness class C,
which ensures that the heated air will reach its destination
and will not leak out of the ventilation system – which
saves energy and money.
Installation
The CWW can be installed in a horizontal or vertical duct,
with the air flow in either direction.
Control
See pages 12 to 15 for a list of regulators, sensors, valves
and actuators.

OPTIGO
Complete regulator with built-in room sensor.
Floating control for controlling three-position
actuators. Cascade connection with minimum limit
for room temperature control. Can be equipped
with external room and/or duct sensor and external
setpoint adjustment. Temperature range 0 - 30°C,
depending on the sensor employed.
Regulator with display. One knob for all settings. For
mounting on DIN rail. Operates with PT1000 sensor
in the range of -20°C to + 40°C. Started/stopped with
”run” signal from the fan.
AQUA24TF
24V supply. The regulator has a built-in controlling antifreeze protection with two alarm relays and automatic
control for heating during stoppage.
REGIO MINI
Complete regulator with built-in room sensor.
Can be equipped with external room and/or duct
sensors. Has two control outputs, e.g. for heating
and cooling in sequence.
RC
24V supply. 0…10V output control signal.
DIP switches are used for basic 20 - 26°C setpoint setting.
The basic setting can be adjusted by ±3°C by means of the
setpoint knob.
RC-DO
24V supply. 0…10V output control signal. The RC-DO has
a back-lit display and a temperature range of 0 - 50°C.

OP5
24V supply. 0...10V control signal output. Operates with
one sensor (room or duct sensor). Can be reset for heating or
cooling control.
OP10
24V supply. Can be reset for 0…10V control signal output
or 3-point control. Two control outputs, e.g. for heating and
cooling in sequence. Input for two sensors and anti-freeze
sensor. Supply air temperature control or room temperature
control with cascade-controlled supply air. Anti-freeze control with heating during stoppage. Output, e.g. for starting/
stopping of fans via 230V~, 5A relay. Programmable oneweek timer for controlling of both fan and heating/cooling.
Terminal for external timer that extends the operating time.
Can be equipped with external setpoint adjuster.
OP10-230
Same functions as the OP10, but with 230V~ supply.
