Very quiet – 25mm double skinned panels provide better acoustic and thermal properties over conventional AHU’s. Reduce installation time – all components are pre-assembled, wired and tested before despatch. Units are delivered in sections where applicable. Simple precise commissioning – minimum and maximum ventilation rates precisely set and limited at AHU requiring no throttling dampers. Energy efficient controls – all models have Ecosmart controls built in (non control options available) providing the most energy efficient and cost effective solution. Part L and energy efficient – motors are IE2 to BS 5000 direct drive and high efficient belt drive. Long lasting – manufactured from highly rigid pentapost design framework with heavy gauge aluzinc panels proving a corrosive resistant shell. 5 year warranty – for peace of mind. No control options have a 2 year warranty Air handling unit shall consist of fan, G4 filter and electric heater battery, DX or LPHW.

Air handling unit shall be constructed with double skinned aluzinc panels on an aluminium Pentapost frame. Air handling unit shall incorporate full Ecosmart control package and constant pressure control. Units will be supplied in modular sections for on-site assembly by the installer; this will also necessitate completion of the wiring between modules. The fan unit will have a 5 year warranty.

Air handling units (AHU, sometimes referred to as ‘air handlers’) form part of the heating, ventilating and air conditioning system (HVAC) that supplies, circulates and extracts air from buildings. Air handling units can be supplied in a range of sizes, and with a variety of capabilities, but typically they comprise an insulated box that forms the housing for; filter racks or chambers, a fan (or blower), and sometimes heating elements, cooling elements, sound attenuators and dampers (that can be operated manually or automatically to regulate or prevent specific air flows).

In some situations, such as in swimming pools, air handling units might include dehumidification. Heating and / or cooling can be generated within the unit itself, or can be provided by connection to the building’s boilers or chillers. Generally, air handling units will be connected to the ductwork within the building that supplies air to and extracts air from the interior, but they can be used to supply and extract air direct to a space, or they may be located on a roof (rooftop units or RTU). Air handling units that consist of only a fan and a heating or cooling element, located within the space they are serving, may be referred to as fan coil units (FCU). Air handling units can be used to re-circulate a proportion of ‘stale’ air within a building, mixing this with fresh air to reduce the amount of air conditioning that is required. They can also include heat recovery, recovering heat from return air and using it to warm the supply air. Fans may be single speed, may have a range of set speeds, or may be variable frequency drive.

Flow rates may also be controlled by inlet vanes or outlet dampers. Air handling units generate noise (and vibration) which can be disruptive, and this can be compounded where ductwork passes between acoustically separate spaces. In this case, acoustic attenuators might be used. In addition, vibration can be generated. This vibration can be isolated by inserting flexible sections between the unit and ductwork and by isolating the unit from the building structure. Where air handling units are located outside buildings, they can be the source of complaints by neighbours because of the noise and vibration they generate and sometimes because of odours they expel (typically where they are serving kitchens). It is important that these units are properly designed, installed and maintained to minimise this disturbance. ‘Wet’ systems, that include water evaporative cooling, can present a hazard to health. Businesses using such systems are required to carry out a risk assessment and put in place procedures to ensure there is no risk to public health.
