Electrolytic Hydrogen Water Generator
(Alkaline ionized water apparatus)

Easily generate electrolytic hydrogen water at home.
Use the power of hydrogen for daily health management.

As our body requires water every day,
most of us pursue clean water as a way to maintain our health.
Unlike mineral water, the electrolyzed hydrogen water generated by the HWP-55
includes plenty of hydrogen, as generated by electrolysis.
For all aspects of daily life, including daily water intake,
and for making drinks such as tea, etc., as well as for cooking,
Fujiiryoki has brought this unique electrolyzed hydrogen water to market
as part of its drive to support beauty and health.

How about incorporating electrolyzed hydrogen water
into your family’s daily efforts for health maintenance?

What is electrolytic hydrogen water?

Electrolytic hydrogen water for gastrointestinal health

One of the main qualities of electrolytic hydrogen water is that it has positive effects for the improvement of gastrointestinal symptoms. For example, many acknowledge its ability to ease any discomfort or an upset stomach may have. In other words, drinking electrolytic hydrogen water, unpleasant gastrointestinal symptoms can gradually be alleviated.

Efficacy or effects of electrolytic hydrogen water

Improvement of gastrointestinal symptoms

Electrolytic hydrogen water alleviates dull feelings in the stomach and stomach discomfort.
It also helps gastrointestinal movement and improves bowel movement.

What are the differences between an electrolytic hydrogen water generator and a water purifier?

A water purifier is used for eliminating residual chlorine and impurities from tap water, in order to make clean water.

An electrolytic hydrogen water generator is used for electrolyzing the purified water from which impurities and chlorinous odors are removed to make electrolytic hydrogen water and acidic water. Therefore, the functionality and characteristics of the generated water are completely different.

The electrolytic hydrogen water generator can easily generate, at home, not only purified water that tastes better than tap water but also electrolytic hydrogen water that is good for health at home.

The secret of electrolytic hydrogen water is the difference in the oxidation reduction potential.

The index that indicates the electrical energy amount of water is known as "oxidation reduction potential" (ORP). The higher the positive value, the stronger the oxidation power, and then the higher the negative value, the stronger the reduction power that deoxidizes oxidized materials.

Electrolytic hydrogen water has a negative value, thus we could say that it has a strong reduction power.

Mechanism of the Electrolytic hydrogen water generator

The apparatus purifies the tap water, and then electrolyzes the water.
By that, electrolytic hydrogen water is generated at the negative electrode with acidic water at the positive electrode.

Note: This site uses the terms "electrolytic hydrogen water" and "acidic water" for the names of generated water.
These correspond to the terms "alkaline electrolytic water" and "acidic electrolytic water" used in JIS T 2004 (water electrolyzer for home use).

Electrolyzation

This product can generate purified water, acidic water, etc.,
in addition to the electrolytic hydrogen water.

Fujiiryoki’s electrolytic hydrogen water generator HWP-55 can generate purified water, acidic water, and sanitized water in addition to electrolytic hydrogen water. Various types of water can be used depending on the purpose.

A digital counter shows how many more liters can be filtered effectively until replacement is needed.
When reaching the replacement timing
When the water flow is stopped, an alarm sound and the replacement lamp will notify you.
When the available water-flow amount reaches 0 liters
When two years have passed since the beginning of use
  • Filtering capacity

    16,000L
    (When free residual chlorine and turbidity are targeted)
  • Replacement guideline

Eco-friendlier with improved water-saving capability

The amount of wastewater (acidic water) generated is very low.

Wastewater (acidic water), which always occurs when producing electrolytic hydrogen water, is kept to a strict minimum.

Wastewater

Approx. 5%

The flow rate when Alkaline Hydrogen Water 1, 2, or 3 is selected is 19:1. This is the top class* in the industry.

* As of February 2014 (based on an internal investigation)

If used within 30 minutes, no water is wasted!

Annually

Approximately 3,400 L
of water can be saved.*
If water of the same water quality (Alkaline Hydrogen Water 1, 2, 3, or purified water) is used again within 30 minutes, all the water can be used without wasting the water that remains in the generator.

If electrolytic hydrogen water is used for three meals a day and for tea within 30 minutes after each meal, the generated wastewater is zero, with a generation ratio of 4:1→19:1

No worry necessary, with the auto power-off function

The auto power-off function turns the power off 30 minutes after use. This prevents the wasting of electricity.

Industry’s top-class water volume

The amount of electrolytic hydrogen water generated by electrolysis is 5.5 L per minute, which is the best in the industry. Thus, a family can use all the water they need.

Each minute

Approx. 5.5 L
(Maximum delivered water amount currently available)

Easy-to-use, long delivery pipe

The pipe used is now longer, at 65 cm, and there is more space around the faucet, allowing users to make better use of their kitchen.

Slim body: Makes placement easy

A compact size of just 12 cm in depth allows users to situate the product in a kitchen of any style.

Hassle-free, with an auto cleaning function

Real-time refresh function

Reduces the amount of calcium sticking to the electrode plates and supports the electrolysis ability.

Auto refresh function

For each 10 L of electrolytic hydrogen water used, 30 minutes after the water is stopped, the electrode plates are automatically cleaned for 10 seconds.
