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 unit is supplied with duct spigots to outside on the right hand side. These can be reversed on site by simply removing the control panel, rotating the unit 180 degrees and re-attaching the control panel.

The Sentinel Kinetic Plus is ideal for larger homes and multiple occupancyunits 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 Kinetic’s BMS capability is also ideal for those commercial applications where landlords or property managers want to monitor and optimise 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.

Product Specification:

The Lo-Carbon Sentinel Kinetic Plus has 2 fully adjustable speeds and a purge setting - maximum. On the front of the unit is a digital controller that can be used to pre-set the speeds to any required air-flow within the performance range. The Sentinel Kinetic Plus models can be mounted vertically in a roof space or on a suitable wall. When mounted in an unheated area ducting should be insulated. Ducting can be attached to the unit horizonally, vertically or both. Left or right hand installation. The unit is supplied with duct spigots to outside on the right hand side. These can be reversed onsite by simply removing the control panel, rotating the unit 180 degrees and re-attaching the control panel. Horizontal and vertical spigots: The combination of spigot options allows installation in confined locations. If vertical and horizontal connection is required on the same outlet/inlet, additional spigots can be supplied. Condensate drain can be taken out through the back, bottom or front of the unit. Using the fittings supplied, the final condensate connection is made outside the unit and can be completed after installation.
