Eco Active Heat Recovery Penthouse Turret W: www.gdl.co.uk T: 01457 861538
Heat Recovery Penthouse Turret The HRPT provides ventilation into spaces all year round. The unit provides 100% fresh air whilst recovering heat to provide winter heating. The unit also provides passive ventilation for summer periods. The unit eliminates the need for space heating, make-up air louvres or openable windows, reducing the overall cost of the ventilation and heating system. The HRPT comprises of two low energy fans providing a duty of up to 0.32m 3 /s each and a plate heat exchanger with an efficiency of 74%. The overall unit is ErP 2018 compliant and has the capacity to recover heat of up to 8kW. The integrated dampers give control over the flow of air through each section. The integral passive section of the unit provides the required summer ventilation with the added benefit of a forced mechanical ventilation system. This allows the system to provide a complete purge of the space when required. Key Features: Low noise operation Air volumes of up to 300 l/s can be achieved Below 35dB noise levels Ensure IAQ and temperatures remain within D of E guidelines Easy to use in room controller Summer boost and night purge Available in a range of colours and finish
EXTRACT SUPPLY 1500mm PASSIVE SUPPLY EXTRACT 1200mm Design The unit is designed to serve spaces with occupancies of up to 32 people. The unit is controlled via a in room CO 2 and temperature sensor to provide the winter and summer ventilation. The standard unit size is 1500 x 1500 x 700H nominal (1500mm square shaft dimension), of which half the unit provides the passive ventilation with the remainder half housing the mechanical fans and the plate heat exchanger. The unit is supplied with a split drop duct and a 1200 x 1200 3-way air diffuser to be mounted onto the ceiling. The unit can also be integrated with ducted systems.

Passive mode: Summer In summer, once the peak occupied temperature is reached within the classroom, the units operate in 'passive mode'. No fans will run but by opening the summer passive damper, air circulates through the unit, by the natural stack/buoyancy effect. Boost mode: If temperatures within the room do not reduce after the passive mode has been in operation for a short period, the summer/extract fan will start to operate to boost the ventilation rate through the space.
Night purge - passive ventilation during unoccupied hours. When external temperatures are low, the space can be ventilated automatically to refresh and cool the space during unoccupied night time periods. This can be achieved by running the units in the 'passive mode', providing free cooling without compromising the building's security. Smart Control The smart room controller is an application configurable wall mounted controller with the ability to integrate into network devices that support BACnet MSTP or Wireless ZigBee mesh network technology. Wireless not available for this model Customisable Touch Screen The touch screen of the room controller offers a customizable user experience with selection of languages, temperature scales, buttons, and screen colours, it also supports the upload of an image or logo that becomes the default standby screen of the device. Custom messages can also be displayed on-screen using BACnet objects when the room controller is integrated via a BACnet MS/TP system. Optional Passive Infrared (PIR) All models can be equipped with a discrete optional passive infrared (PIR) motion sensor. With the embedded sensor, the room controller uses advanced occupancy routines to generate automatic energy savings during occupied and unoccupied periods without sacrificing occupant comfort.
