PURA

Units are designed to make life easier for installers maintenance teams and the end-user.

Key Benefits

Accessibility

Doors: All access doors are hinged and fitted with at least one lockable handle.

Viewports & Lights: Polycarbonate double port-holes are circular, optically transparent and UV stabilised for durability. Bulkhead lights are included and also fitted to both fan chambers for easy visual inspection inside.

Thermal Treatment Capabilities

Covering an airflow envelope of 0.5 – 2.5 m3/s, the PURA units are available as double decked or vertical arrangement and side by side, or horizontal, arrangement. Independently tested against BS EN 1886 – Ventilation for buildings; Air Handling Units; Mechanical performance, the PURA Units achieve a classification of L1, D1 & T3 and a filter bypass leakage rating below 1%, allowing for a usable filter class up to ePM1 90%.

Wiring & Connectivity

Internal Wiring: Innovative HDC3 system for safe and speedy interconnectivity of sections, offering extra protection against dirt, mechanical stress and moisture. The new HDC3 system uses high quality couplings that are responsible for secure electrical functioning and guaranteed electrical signal integrity.

Construction

Panels: Standard double skin with a soft core infill (50mm mineral wool (60kg/m3)), and secured to the frame with a new Stop & Block system for enhanced air tightness. With the new Stop & Block system, panel assembly and fitting are drill free and no fixing screws are used. Panels can still be easily removed with the performance of the unit remaining unaffected, thus ensuring good seals throughout the whole of the product lifetime.

Frame: From the innovative Stop & Block system, the extruded aluminium pentapost frame has a special profile design for quick assembly whilst guaranteeing unit air tightness and performance.

Base: Factory made 100 x 50mm galvanised steel base frame, with 2 sets of rectangular lifting slots on each side.

Weatherproofing Kit: Double pitched roof with a mica finish completed with flashing on joints. Weather cowls with dampers are factory fitted with spring return actuators.

Component Parts

Filters: Rated according to EN ISO 16890, the standard filters achieve efficiencies up to ePM1 70% (ISO 16890) thus promoting good supply air quality. Units have Click & Slide rails, specially designed for easy maintenance.

Fans: Direct driven free-running, backward-curved with sealed for life ball bearings, completed with an electronic commutated motor, providing infinite speed control. Each fan section is factory fitted and wired to an IP66 isolator.

Energy Recovery Components: Components transfer thermal energy from the extract air to the incoming supply air, resulting in lower heating demand downstream to the system.

Heating & Cooling: For heating, an electric heater or hot water coil can be used. For cooling, a chilled water or refrigerant coil can be used.

Controls (Machine Management)

Kinairtico Controller: An in-house engineered pre-programmed controller available as a three phase inset backplate specifically designed for use with the range of PURA units. Various modes of operation are determined by a set of parameters pre-set at the factory during testing and once set-up, no further adjustment should be necessary. The Kinairtico is our unique, innovative Indoor Air Quality and energy recovery management device that delivers efficient, clean and comfortable ventilation whenever it is required. Available as standard with built-in screen for easy set-up, the Kinairtico is also available with remote, wall-mounted push button monochromatic display unit or colour touchscreen.

Key Applications

PURA units minimise utility bills by using heat / coolth recovery technologies for improved energy savings and increased performance.

The range of PURA units take in outdoor air, filter it and deliver a purer and fresher supply of air that enhances the level of Indoor Air Quality for well-being and productivity.

PURA units are suitable for a variety of building applications, including:
Industrial
Commercial / retail
Recreation / leisure
Public buildings
Healthcare
Schools
