Applications:
Schools
Institutions
Gyms
Restaurants
Etc.

What is a Vent?
Packaged fresh air system with heat recovery
Rotating and cross flow heat exchanger
High efficiency direct driven fans
Frequency controlled
Integrated control

VENT R
VENT R units are particularly suitable for comfort ventilation where high efficiency (up
to 80%) and small dimensions are required. An advantage of high efficiency is that the
extra reheat coil can be left out, thus reducing the installation costs.

VENT C
VENT C units are particularly suitable for ventilation in places where the fresh air should not
get into contact with the exhaust air. Therefore cross flow heat exchangers are especially
suitable for industrial use and ventilation of humid rooms such as changing rooms and
bathrooms. The efficiency is about 55% dry / 65% wet.

CABINET CONSTRUCTION
Hot-dip galvanized self bearing cabinet with 50 mm insulation complying with
EN 1886
Internal partion walls are double skinned panels with 30 mm insulation
Large inspection doors with hinges, handles and locks
Circular duct connections with rubber sealing gasket on and rectangular duct
connections on the inlet to provide good air distribution through the filters
and circular duct connection on the outlet on VENT 6
Delivered in one unit with easy manoeuvring through standard doors, but
VENT 6 can be separated in three parts for easier manoeuvring
Suitable for outdoor installation due to the sturdy construction (requires a roof
covering which is an accessory)
Base frame (adjustable feet's as accessory)

FANS / MOTORS
High efficient Ziehl Abegg plug fans with low
dynamic pressure drop and factory balanced
Fan wheel is connected to the motor shaft
by means of a taper lock sleeve
Frequency controlled single phase
Grundfoss motors
Fans are fitted with pressure transmitters,
constantly monitoring the air volume and
adjusting it to the required value.
Fan/motor construction is fastened with
finger screws for quickly removing the fans
for inspection and cleaning.

HEAT EXCHANGERS
Non hygroscopic heat wheel with up to 80%
temperature efficiency at nominal air volume
Frequency controlled motor for heat output control
and free cooling
Purge zone
Aluminium cross flow heat exchanger with 55% to
65% efficiency (dry/wet) at nominal air volume
Modulating by pass for heat output control, free
cooling and defrosting
Stainless steel condensate tray on exhaust side

9. © Dantherm A/S
FILTERS
F5 bag filters with large filter area on exhaust air side
F 7 bag filters with large filter area on fresh air side
Easy to change filters with an eccentric clamping
mechanism, which gives a perfect seal (filter bypass
leakage 0.5%)

ACCESSORIES
Hot water reheater coil for external duct connection,
ready to mount direct to the Vent units duct
connection. Electrical connection of the valve motor
and frost thermostat happens by means of a cable,
which is directly plugged in into the Vent unit.
Electric reheater with a step less heat output.
Electrical connection of the controls and safety
thermostats happens by means of a cable, which is
directly plugged in into the Vent unit.
DX or cold water cooling coils for duct connection
Multi leaf dampers for duct connection
Roof cover for outdoor placing

CONTROLS
Integrated control with micro processor built in into
the unit
User friendly control panel with large display and
easy navigation through the setting points
Program timer with 20 steps
Communication through Lon Works, or a simple BMS
communication module.

TEMPERATURE CONTROLS
Temperature control
Combined control of supply and room air temperature
(Outdoor temperature < 15°C supply air control, > 15°C
room control)
Control of room air temperature
Control of supply air temperature
Other methods of temperature control
Constant supply air temperature without a reheating coil (VENT R)
Night cooling summer
Override of preset temperature by means of an external 2-10V
control signal

16. © Dantherm A/S
AIR VOLUME CONTROLS
Constant air volume control
VENT 2 Min. 400 m3/h Max. 2200 m3/h
VENT 4 Min. 600 m3/h Max. 3500 m3/h
VENT 6 Min. 800 m3/h Max. 5200 m3/h
Forced air volume control (Air quality sensor / humidity sensor)
Variable air volume control (Duct pressure sensor)
Compensation for dirty filters

17. © Dantherm A/S
ADDITIONAL CONTROL FUNCTIONS
Manual operation (Overrides temperature, air volume in a set time)
P.I.R sensor (If a movement is registered the unit switch over to Manual operation)
Filter guard (Not possible in VAV operation)
Motion program for the rotary heat exchanger when not in use to prevent the
heat exchanger getting dirty
Communication to an BMS system or Lon Works communication (accessory)
Start signal for cooling 2-10V (water cooling coil), or ON/OFF (compressor)
Alarm functions
Start signal for hot water pump

ADVANTAGES
Both cross flow heat exchanger and rotary heat exchanger are available.
Can be used directly as an outdoor unit together with a roof kit.
Easy plug and play installation
Low internal pressure loose with high efficient fans. Therefore a low SFP figure
and running costs.
User friendly large display.
All text in the control display in full words.
Step less air volume regulation.
Short delivery time (units are normally in stock).

ADVANTAGES
Advantages in comparison to block module AHU´s
Easier to find space for several smaller units then for one big
one
Installation costs are smaller for several small units then for
one big one
Plug and play between the Vent unit and the controls as both
are factory tested together from Dantherm before leaving
the company
Ducting can be smaller and therefore cheaper and easier to
hide
Different room conditions are easier to control by several
small units then one big one
Under maintenance or malfunction only a part of the
ventilation system is interrupted
Short delivery time as Vent units are produced in series and
are in stock
Possible to modernize a building in stages
