Duct Mounted Units
Duct based UVGI Systems are needed in several situations where either the AHUs do not have the required space for UVGI installation or only a certain specific zone is to be provided with purified air.
Even though UVGI installation in AHUs has distinct advantages as compared to In-duct UVGI, there are some positives of duct installation as well. Some are listed below:
- Longer exposure distance is possible even though the air velocity is higher than AHU.
- Maintenance work can be considered to be easier in certain situations as compared to AHUs, though not always.
- Air purification is done closer to the occupied space, which in some cases can reduce the issues of re-contamination in ducts post-UV.
InviroTech Spectra UVGI Systems are built with superior design features that include double glass construction of UVC Lamps with following benefits.
- Double glass construction keeps the UVC performance high even with low temperature air moving over the lamps.
- IP68 Construcion of lamps provides unmatched electrical safety due to complete isolation of live parts from moist air.
InviroTech Spectra Duct UVGI series are built with features that try to overcome the maintenance challenges present due to the ducts being at elevated level. The in-duct range has three different types of mounting designs, each of which has been designed to overcome the challenges and to make it easier for the user to operate, monitor and maintain the UVGI system.
// APM Series
Advance Panel Mount
Spectra APM Series is designed for direct installation in the ducts. These are 100% factory assembled units and can be easily installed. The door panel is insulated to prevent condensation due to cold air.
The primary benefits of the APM series are the HODS lamp sets and ease of maintenance. HODS (High Output Double Skin) lamp sets ensure that UV lamp intensity is higher at the low temperatures of supply air. Secondly, the ease of maintenance for the UV system is greatly improved as the lamps can be accessed and replaced without the use of any tools whilst keeping safety in mind with the limit switch.

// HFM Series
Horizontal Flange Mount
For installation in ducts. Only a small rectangular cutout is to be made in order to install the system. The HFM model comes with double skin lamps, and a PU insulated flanged-mounting to prevent condensation due to cool air.
The primary benefits of the HFM series are the HODS lamp sets and lamps that are perpendicular to the air steam. HODS (High Output Double Skin) lamp sets ensure that UV lamp intensity is higher at the low temperatures of supply air. Having lamps perpendicular to the air stream can help lower the required lamp quantities however, they also require significant space in the ducting.

// SIM Series
Simple Insert Mount
Meant for smaller ducts and ducted fan coil units. A small 50 mm diameter hole cutout is needed for every lamp. The key benefit of the SIM Series is the size and ease of installation, however it is not generally used for larger airflows.
SIM series can use U-shaped in order to significantly increase the lamp length without a great impact on space requirements.
