【New Product Launch: Heat Exchange Ventilation System】 Ductless type 'LT-30Reno' for remodeling and renovation, washable heat exchange element! High airflow duct type 'LWZ-280' (Nihon Stiebel)

Recommended for renovations and remodeling. The ductless heat exchange ventilation system 'LT-30Reno', which can be installed in existing natural air supply vents, is now on sale.

It is also recommended for the replacement of air through natural ventilation openings and the introduction of partial heat exchange ventilation. Features ■ Compatible with various types of pipes for through-holes (VU pipes, VP pipes, SU pipes) The required components vary depending on the type of pipe. Please contact us for details. ■ Existing outdoor air hoods can be utilized depending on conditions such as wall thickness An optional dedicated outdoor air hood is available in four colors. ■ Achieves a maximum heat exchange rate of 85% despite its compact size Contributes to reducing heating and cooling costs. ■ Standard equipped with pollen-resistant filter Removes approximately 85% of aerosols of 10μm in the European G3 class. ■ Filter option: Allercatcher® AI (newly released) In combination with the G3 filter, it also addresses concerns about viruses, allergens, deodorization, and antibacterial measures. ■ Easy maintenance Simply vacuum or wash (only standard filter) when the lamp on the main unit lights up. * For more information about Allercatcher® AI, please refer to the "Detailed Information" below.

• Ventilation and Exhaust

A high air volume design that can cover an area of approximately 270 square meters with just one unit. Both sensible heat exchange and total heat exchange types allow for the washing of the heat exchange elements.

A new high-capacity model with a large airflow design has been introduced in the Japanese Stiebel heat exchange ventilation system. ■ Large Airflow Design Equipped with a high static pressure turbo EC fan motor. Even when pressure loss occurs, the motor automatically adjusts its rotation speed to maintain the set ventilation volume. ■ Both Sensible Heat Exchange and Total Heat Exchange Elements Can Be Washed The total heat exchange element uses a solid membrane. With high waterproof and moisture-permeable properties (allowing only water vapor to pass while blocking liquid moisture), it is now possible to wash the heat exchange element of the total heat exchange type, which previously could not be washed. This allows for the heat exchange element to be kept clean over long periods of use. ■ Built-in Preheater The wall-mounted type is the only one with a built-in preheater. By heating the incoming outside air before heat exchange, it maintains the planned ventilation volume and high heat exchange rate even in cold periods and regions. ■ Bypass Mode In summer, when the outside temperature is lower than the indoor temperature, it is possible to directly intake outside air without heat exchange for cooling. The incoming outside air passes through a filter, just like in heat exchange ventilation, allowing for clean outside air intake without the need to open windows.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
