e2 10回熱回収換気清浄システム

📌 The background for preparing this project
is as follows.

Although we spend most of our time indoors, due to fine dust, external noise, heating and cooling loss, and the structure of living spaces,there are many days when it is difficult to open windows enough for ventilation. This happens quite often.

We wanted to solve this problem not simply by selling a single ventilation device,
but by providing continuous ventilation management tailored to the space and living environment. That was our goal.

So, based on the core ventilation components from Germany's LUNOS, and considering domestic installation environments and usage conditions,
we have assembled and inspected ourselvesthe e2 Heat Recovery Ventilation Purification System to prepare for you.

The e2 is designed for living spaces where it is difficult to keep windows open continuously,enabling planned air exchange andconsidering heat loss management together so that you can benefit from both.This ventilation system was developed in cooperation with Germany to ensure that, even after product sales, we continue to provide installation condition reviews, usage guidance, filter management, and consultations.Ventilation service is our goal.

This Funding amount will be used to reliably establish the initial domestic assembly and inspection system for the e2 heat recovery ventilation purification system, as well as to refine the quality verification and usage/management standards for the first production products.

💡What we want to create is 
to propose a better air environment for living spaces that need ventilation and,
to make every moment people breathe more comfortable.

📌 This project we are presenting has this story.

✅For living spaces where window ventilation is difficult,
e2 Heat Recovery Ventilation Purification System

e2 Heat Recovery Ventilation Purification System enables continuous ventilation without loss of indoor thermal energy.
(Ventilation possible 24 hours a day, 365 days a year)

In living spaces where it is difficult to keep windows open for long periods,planned air exchange and heat loss management,
and after installation,usage and management are all considered together in this clean ventilation system.

💡Wait a moment here!
What is the difference between a regular ventilator and e2?

Regular ventilator

Regular ventilator is a simple ventilation device focused on expelling indoor air to the outside. In this process, indoor heating and cooling energy can also escape together, making it burdensome to use continuously for long periods, and there are limitations to systematic indoor air quality management.

e2 Heat Recovery Ventilation Purification System

On the other hand,the e2 Heat Recovery Ventilation Purification System expels polluted indoor air whilestoring the thermal energy in a heat exchange element. When fresh air from outside is brought in, the stored thermal energy is transferred back, reducing the loss of heating and cooling energy in aheat recovery-based individual ventilation system.

The e2 is based on the core ventilation parts of LUNOS Germany.

We do not simply import and sell, but assemble the product and inspect it,
taking into account domestic installation environments and usage conditions, and then provide it as a finished product.

We check the product configuration, exterior finish, and operation before shipping.
We aim to establish product quality standards through domestic assembly and inspection processes.

02. The dilemma between window ventilation and heat loss
A heat recovery ventilation method that considers both aspects

There are many days when it is difficult to keep windows open due to fine dust, external noise, and heating or cooling energy loss.

e2 preserves thermal energy during the process of exhausting indoor air and introducing outdoor air.
Preserving thermal energy with aheat recovery-based individual ventilation method.

It is designed to maintain clean
indoor air quality through plannedair exchange without having to keep windows open at all times, tailored to your living space.

03. One product, various spaces

An important direction of e2 is that
a single ventilation unit can be expanded to suit various usage environments.

For office use

For single-family home rooms

For car use during car camping

For camper vans

✅Detached houses, apartments, offices As well as indoor spaces that require ventilation, such as these,
While parked,Camping and car camping environments It can also be used in these situations.
 
Especially during camping and car camping, the risk ofcarbon monoxide is very high.
In spaces that are easily sealed, such as camper vans, car camping, and tents, accidents involvingcarbon monoxide poisoning have actually occurred repeatedly when using heaters, charcoal, generators, or gas water mats.

The e2 is aheat recovery ventilation system that makes you consider the importance of ventilation in enclosed spaces.

The e2 heat recovery ventilation and purification system Provides continuous supply and exhaust of air indoors for 24 hours without heat loss. You can enjoy a safe and pleasant camping life through it.

✅  With just one e2 heat recovery ventilation purification system,
Economical installation possible in various places.

We One e2 product to ventilate where needed,provide fresh air to various spaces, and would like to offer this. We review the ventilation direction suitable for each space,and the base kit applicable to the space, and aim to provide a service that reviews these together.

04. Ventilation service that shows installation convenience, airtightness, and maintenance management.

You can directly check how the main unit is installed, how it combines with the base kit, and how to manage the filter.
You can also see how the exterior and interior are finished.

In particular, the ventilation systemrequires proper finishing and airtightness. is important.

To reduce drafts, rainwater, and noise intrusion,airtight pads, external hoods, installation finishing, and filter replacement accessibility must all be carefully checked to ensure long-term comfort.

Even after product sales, e2 reviews installation conditions, provides usage guidance, and manages filters,
offering consultation as well. Ventilation service is our goal.

What we want to create is not just a simple ventilation device.

We aim to offera better air environment for living spaces that need ventilation,
and establishmanagement standards that allow for long-term use even after installation.
