Ductless heat exchange ventilation system "SeseragiS400"

Now Available: Prevents the decline in heating and cooling efficiency, contributing to energy savings! Completely waterproof design allows for hygienic maintenance.

The ductless heat exchange ventilation system "SeseragiS400" switches between supply and exhaust air with a single fan by repeatedly rotating the fan unit in both forward and reverse directions. During exhaust, heat and moisture are stored in the heat storage element, which are then released into the room during supply. With excellent maintenance capabilities and the ability to wash the heat exchange element (heat storage element) thoroughly, it suppresses the reduction of supply air volume due to clogging, allowing for a stable intake of fresh air. By introducing a heat exchange ventilation system, it can reduce the loss of internal heat due to ventilation and save electricity consumed for heating and cooling. Unlike traditional ducted ventilation systems that require long ducts to distribute air throughout the house, the energy consumption of the ductless "SeseragiS400" is exceptionally energy-efficient. One of its major attractions is made possible by its ductless structure, which has low air resistance. 【Features】 ■ Hexagonal honeycomb high-performance heat storage element ■ Completely waterproof design and hygienic maintenance ■ Dedicated, uniquely developed fan motor ■ Windproof backflow prevention outdoor hood "KK2" "NWC" ■ Standard controller "VMPX-N" without sensor ■ Automatically measures carbon dioxide concentration, displays it, and controls ventilation "VMPX-AQ"
