New ductless solution uses window-frame kit, integrated diffuser

Older apartments and standalone homes without existing duct systems now eligible

About 7 million pre-mandate households targeted as new customer base

Kyung Dong Navien announced Monday it will launch a ductless installation solution for its dehumidifying ventilation air purifier, enabling setup without embedding ducts in ceilings.

The core advance is an expansion of compatible housing types. Previously, homes without existing ventilation ductwork inside their ceilings — including older apartment complexes and standalone houses — were difficult to equip with ventilation air purifiers.

The new solution incorporates a window-frame kit that serves as an air passage between indoors and outdoors, along with an integrated supply-and-exhaust diffuser that handles both airflows simultaneously. The design allows the product to be installed in occupied homes without any ceiling duct construction.

Installation time has also been shortened. Depending on site conditions, setup can be completed within a day and, in some cases, in as little as half a day, the company said. Customized installation accounting for each home's layout — including whether a balcony has been enclosed — is also available.

Kyung Dong Navien sees the ventilation equipment market for existing housing as a sizable opportunity. Under regulations governing building equipment standards, ventilation systems have been mandatory in newly built apartment complexes of a certain size since 2006. A 2020 revision to those rules expanded the requirement from complexes of 100 units or more to those with 30 units or more.

Homes built before the mandate took effect, however, frequently lack ceiling ductwork entirely. Citing Ministry of Land, Infrastructure and Transport residential environment statistics, Kyung Dong Navien said approximately 7 million such households exist. The company's strategy is to bring older apartment complexes and standalone homes — where installation had previously been impractical — into its potential customer base through the new ductless approach.

"By launching the ductless installation solution, we will significantly expand the reach of our dehumidifying ventilation air purifier and open new possibilities in the indoor air quality market," said Kim Yong-beom, head of sales and marketing at Kyung Dong Navien. "We will continue to advance our lifestyle air solution technology to provide more customers with a comfortable living environment."
