To f i l t e r, heat and attenuate. Clean, warm and quiet air systems can be obtained by making the best use of the vast accessory range offered by HELIOS. Whether for circular or rectangular ducting: the complete range includes all sizes and performances, perfectly designed to operate with HELIOS fans. This gives flexibility for successful design and installation. Air filters – for wall and ceilling installation. – with flanges on both ends for in-line installation with ducting. – Air filter boxes fit all relevant nominal duct diameters. Water heaters (LPHW) and electric heaters for convenient tempered intake air. Electric heaters with comfort control from the new electronic temperature control system EHS. Attenuators in all sizes and designs for installation in rectangular or circular ducting, made from galvanised steel or flexible aluminium. 211

212 Air filter for wall and ceiling installation LF Simple to install components for effective solutions. The controlled intake of external air is a requirement for a good ventilation system and is necessary to meet the regulations in many cases. The filtering of intake air is a must nowadays. For this reason HELIOS offer simple and effective components to suit various installation conditions. Accessories for air filters Complete kit to monitor the pressure drop and thus how dirty the filter is. The gold coated connector makes it suitable for BMS applications. Pressure range 100 – 1000 Pa,...

215 Electronic temperature controller EHS for electric heater batteries Electronic temperature controller EHS for electric heater batteries Electronic controller for electric heater batteries installed in ventilation systems. Monitoring the intake air temperature against the required temperature and controlling the heating element. Stepless control is achieved by a proportional timer which allocates power in time intervals. The relation between on and off time periods is adjusted to the required heat (switching sequence in compliance with electricity boards even with high switching power)....

216 Water heater batteries (LPHW) for rectangular ducting WHR-K Water heater (LPHW) for connection to rectangular ducting. Casing made from galvanised steel with flanges on both sides to fit the HELIOS fan range. Heating elements made from copper with aluminium fins. Max. operation temp. tmax. 120 °C. Max. operating pressure 8 bar. Water pipes with external thread. Installation Heater must be installed downstream of the fan in the air flow. If required to be fitted upstream consider that the air flow must not exceed the fan’s max. air flow temperature. To prevent the heater from becoming...
