Increased Performance
The Sentinel Kinetic Plus benefits from the latest high efficiency, backward
curved impeller design, ensuring the lowest possible energy consumption, ultra
quiet operation and an exceptional performance range covering small one bed
apartments to the largest of houses.
For scenarios where noise is a critical issue, an Acoustic Enclosure is available to reduce breakout noise and the Acoustic Top Box will reduce in- duct noise at key frequencies.
Care Homes & Student Accommodation
The Sentinel Kinetic Plus is ideal for larger homes and multiple occupancy
units such as care homes and student accommodation. Capable of 400m3 /hr at
150Pa, the unit can extract from up to ten bathrooms and a communal kitchen
while still achieving almost 90% heat recovery. The fully automatic capability
of the Kinetic range means that adequate ventilation is always achieved.
The Kinetics’ BMS capability is also ideal for those commercial applications where landlords or property managers want to monitor and optimize building performance and maintenance. The Kinetic BMS can provide status information and its self diagnostics can report if any fault is found.
Spigot Options
Spigots may be re-positioned to give horizontal connection or a combination of
vertical and horizontal connection
Optional 180mm/200mm spigots can simplify connection in commercial installations where larger diameter duct work has been used.
Quick Change Filter
As many systems are placed within cupboards the unique filter design folds as
you remove it to ensure easy access in restricted spaces.
integral Humidity Sensor
The integral humidity sensor increases speed in proportion to relative
humidity levels, saving energy and reducing noise. The sensor also reacts to
small but rapid increases in humidity, even if the normal trigger threshold is
not reached. This unique feature ensures adequate ventilation, even for the
smallest wet room. The night time relative humidity setback feature suppresses
nuisance tripping as humidity gradually increases with falling temperature.

Consultant’s Specification
Operation
The supply and extract ventilation unit shall be as Sentinel Kinetic Plus as
manufactured by Vent-Axial and shall be sized as indicated on the drawings and
shall be in accordance with the particular specification.
Supply air to the room shall be pre-heated by the extract air via the integrated composite plastic counterblow heat recovery cell. The Sentinel Kinetic Plus shall automatically vary the ventilation rate via EC/DC motors, as it receives signals from one of the optional interconnected sensors.
When a signal is received, the fans shall either vary their speed proportionally or on a trickle and boost principle.
The unit shall have the facility to commission the supply and extract fans individually via in-built minimum and maximum speed adjustment, or alternative wired remote control unit. The fans themselves shall have independent, infinitely variable speed control.
Unit Specification
The unit shall be manufactured with an ABS outer case construction, and
incorporate a reversible core to allow for left or right hand mounting
The unit shall have a high efficiency composite plastic counterblow heat exchanger, supply and extract filters, automatic summer bypass, integral minimum and maximum infinitely variable speed controls with facia mounted failure indication
The unit shall have low energy, high efficiency EC/DC fan/motor assemblies with sealed for life bearings. The impellers shall be high efficiency backward curved centrifugal type.
The unit shall have a heat exchanger cell with a thermal efficiency of up to 92% when tested to EN 308. This shall be protected by ISO 45% Coarse (G3) grade synthetic filters on supply and extract. Complete with a condensate drip tray and drain connection.
To reduce breakout noise, the MVHR unit shall be provided with an Acoustic Enclosure of steel construction lined with class ‘0’ acoustic foam. To reduce in-duct noise, the top of the MVHR shall be fitted with an Acoustic Top Box to provide attenuation to the 4 ducts of the unit. This Acoustic Top Box shall be of steel construction lined with acoustic class ‘0’ foam with the MVHR spigots linked to the Top Box via 4 separate attenuated ducts. The acoustic enclosure and top box shall each be independently tested for noise to BS EN 13141-7.
The unit shall be constructed with a removable Core allowing full maintenance access. The removable Core shall provide access to the following:
- Supply and extract filter
- Heat exchanger
- Access to the electrical connections
Access shall be provided for wiring termination and setup/commissioning. The backlit LCD user interface therein may be duplicated for remote mounting if required.
Units shall be as manufactured by Vent-Axial Ltd.
The MVHR unit shall incorporate an Expanded Polystyrene (EPS) inner chassis with custom motor and impeller mounting features. The inner chassis will assist in reducing noise and act as a large anti-vibration mount to avoid transmission through to the back mounting plate or the base of the unit.
The MVHR unit shall be tested to ensure it meets the maximum allowable vibration of no more than 1mm/s, measured on the unit wall fixing points.
Sound tested to BS EN 13141-7:2010
Standard Controls
All Sentinel Kinetic units shall incorporate the following functions
integrally mounted, pre-wired and factory fitted by the manufacturer:
- Integral infinitely variable fan speed control on supply and extract
- Integral min/max ventilation control/set point
- Integral BMS input/output interfaces – control and status indication
- Heating interlocks
- 0-10V proportional speed adjustment
- Volt free contacts
- 24V sensor supply
- Integral on/off or trickle boost function from remote switch, e.g. PIR occupancy detector
- Fully automatic summer bypass
- Switched Live input with adjustable ‘delay-on’ feature
- Fan failure or component failure indicated via individual fault code display
- Running time counter
- Control panel PIN number lock
- Automatic frost protection effective to -20°C
- The unit shall incorporate an integral humidity sensor with the following features:
- Ambient Response; Raises the humidity trigger point as dwelling temperature reduces
- Rapid Response: Monitors the rate of change in humidity and triggers increased airflow even if the humidity trigger threshold is not reached
- Proportional Response; Incrementally increases the fan speed to reduce noise and reduce energy consumption
- The unit shall be controlled by the ‘Sentinel’ control devices (enablers and sensors) as detailed in the schedule or on the drawings.
- Tool free filter access
