Vent-Axia’s Sentinel Totus2 Demand Energy Recovery Ventilation (D-ERV) system has been shortlisted within two categories in this year’s H&V News Awards. The innovative D-ERV system has been nominated for both Air Movement Product of the Year and Commercial HVAC Product of the Year within these prestigious annual industry awards.
Held at the Grosvenor House Hotel on London’s Park Lane on Thursday the 25th April, the H&V News Awards will be attended by over 1,000 influential heating and ventilation specialists from across the whole supply chain. The awards recognise and reward the achievements of the UK’s diverse heating and ventilating sector, with winners selected by a panel of judges made up of over 50 esteemed industry experts.
The Sentinel Totus² is part of Vent-Axia’s innovative Lo Carbon™ initiative which aims to offer the latest low carbon ventilation technology in order to reduce building energy consumption and carbon emissions. Integrating the proven Demand Ventilation control concept with high efficiency EC/DC motor technology and a state-of-the-art counterflow heat recovery cell the Sentinel Totus² achieves up to 94% energy recovery.
In addition, the Sentinel Totus² boasts reduced sound levels which are achieved through the use of high density acoustic insulation and efficient air paths which lower turbulence, system noise, and reduce the SFP to below 1.8w/l/s.
Meanwhile the Sentinel Totus² also features a 100% summer bypass. As a result, when temperatures rise the airflow from the heat exchanger is automatically closed off and simultaneously a bypass opens which the cool air flows through.
With customer comfort a key issue the Sentinel Totus² frost heater control also provides top-up heating as well as a frost protection function, eliminating cold draughts and the need to fit duct mounted heaters.
Designed to operate on the principles of demand ventilation the Sentinel Totus² responds to the precise ventilation requirements of a room at any one time providing the right level of supply and extract airflow when required, making it ideal for schools, hotels, theatres, offices and other environments with changing occupancy patterns. It also recovers maximum energy (heat and cool) from the extracted air, transferring it into the fresh air supply via the unit’s integral high efficiency counterflow heat exchanger, significantly reducing fuel consumption and energy costs.
The Sentinel Totus²’ demand operation can be triggered by its response to room occupancy according to a range of different sensor readings. These can include Timeclock or PIR occupancy detection to activate the unit, with additional proportional airflow control from a combination of sensors; CO2, humidity or temperature.
Independently rated and tested to EN308, the Sentinel Totus² incorporates energy efficient EC/DC motor technology, which is proven to use over 30% less energy than conventional AC motors. Automatic air-conditioning and heating interlocks enable Sentinel Totus² to optimise energy recovery performance further and provide free cooling during summer through bypass optimisation.
