Notice of participation in "Food Factory (FF) 2025" from Wednesday, October 15, 2025, to Friday, October 17, 2025.

"EcoSara" achieves energy savings through zero-energy pre-cooling and reheating. It processes humidity by supplying dry air indoors.

"EcoSara" is a dehumidifying air supply unit that performs pre-cooling and re-heating with zero energy consumption. It not only reduces the energy required for cooling dehumidification but also eliminates the need for a reheat thermal source (such as hot water or electric heaters), achieving energy savings while providing comfortable, dry air for indoor environments. There are examples of reducing primary energy consumption by 78% in food factories (with a payback period of 2.5 years for this case). It is also suitable for facilities that require a large amount of outside air for ventilation. Awarded the Energy Conservation Grand Prize in 2021! (Product and Business Model Category) Award Theme: "Energy-saving air conditioning solution using a dehumidifying air supply unit with 'zero energy pre-cooling and re-heating'" 【Features】 ■ Pre-cools air that has been cooled and dehumidified by outside air using cooling coils, utilizing the thermal energy of outside air for re-heating ■ Contributes to significant energy savings and reduced environmental impact ■ Easy maintenance with a touch monitor ■ Remote monitoring available via smartphone or PC *For more details, please refer to the PDF materials. Feel free to contact us with any inquiries.

Dehumidification and fresh air supply with 'EcoSara' (latent heat treatment), while each air conditioning system manages room temperature (sensible heat treatment)!

We would like to introduce the implementation results of "EcoSara," handled by Sankei Equipment Industry Co., Ltd. The combination patterns include three types: air conditioning units, FCUs, and air conditioners. "EcoSara" performs dehumidification and fresh air supply (latent heat processing), while each air conditioning system is responsible for room temperature (sensible heat processing). It has been implemented in food factories in Hokkaido, Ibaraki, Gunma, Hyogo, Saitama, Shizuoka, and Aichi, as well as in a food supermarket in Aomori and offices in Tochigi and Saitama. [Food Factory Implementation Example] ■ Specifications: Dehumidifying and humidifying dual-purpose unit, indoor ■ Airflow (m3/h) × Number of units: 6000 × 1 *For more details, please download the PDF or feel free to contact us.

It can be reheated with atmospheric heat, eliminating the need for a heating source, saving energy and costs!

We would like to introduce the energy-saving dehumidification flow of "EcoSara," handled by Sankei Equipment Industry Co., Ltd. It can reduce the cooling heat load of zero-energy pre-cooling, which also minimizes the cooling source and power demand, leading to energy savings and cost reduction. Additionally, it can be reheated using ambient heat, eliminating the need for a heating source, thus achieving energy savings and cost reduction. Please feel free to consult us when needed. 【Features】 ■ Primary cooling dehumidification using a sensible heat exchanger (zero-energy pre-cooling) ■ Secondary cooling dehumidification using cooling coils (utilizing 7°C chilled water) ■ Reheating using a sensible heat exchanger (zero-energy reheating) *For more details, please download the PDF or feel free to contact us.

The main cause is the inflow of drafts! This leads to the growth of mold due to condensation and the intrusion of insects and dust, worsening the sanitary environment.

Concerns related to food facilities include the intrusion of insects and dust, condensation in cooling systems, powder adhesion, condensation at ceiling vents, and mold on ceilings and walls. The main cause is the inflow of drafty air. The inflow of humid drafty air leads to condensation, which causes mold growth and the intrusion of insects and dust, worsening the sanitary environment. Condensation occurs when the dew point temperature of the air is higher than the surface temperature. If you have any concerns, please feel free to consult with us. 【For these concerns】 ■ Intrusion of insects and dust ■ Condensation in cooling systems ■ Powder adhesion ■ Condensation at ceiling vents ■ Mold on ceilings and walls *For more details, please download the PDF or feel free to contact us.

Final answer to the solution! Introducing positive pressure in EcoSara.

We will introduce the flow for solving issues such as drafts and condensation. Solutions such as pressurization through the introduction of outside air, pressurization through the introduction of cooled and dehumidified air, and pressurization through the introduction of re-heated dehumidified air have disadvantages, including energy costs. By using "EcoSara" for pressurization, there are no drafts, no condensation, and no decrease in room temperature, while achieving reasonable energy costs. 【Features of Pressurization with EcoSara】 ■ No drafts ■ No condensation ■ No decrease in room temperature ■ Reasonable energy costs *For more details, please download the PDF or feel free to contact us.

Monitoring the indoor temperature and humidity environment with a touch monitor! A case study that solved the problems of a food supermarket.

We would like to introduce a case study of the implementation of "Eco Sara" at a certain food supermarket. The store had concerns about eliminating condensation and mold, as well as improving the hot summer and cold winter conditions in the sales area. Therefore, "Eco Sara" was introduced in a newly established store, creating a hygienic and comfortable environment in both the sales area and the workroom, free from condensation and mold. 【Case Overview】 ■Challenges - Wanted to introduce dehumidifying air conditioning but keep costs down ■Effects - Energy-saving through zero-energy pre-cooling and reheating even with dehumidifying air conditioning - Reduced cooling load, allowing the sales area air conditioning to be turned off *For more details, please download the PDF or feel free to contact us.

A simple solution for "positive pressure in low humidity"! Introducing case studies of "EcoSara," which makes dehumidification enhancement easy.

We would like to introduce a case study of the "EcoSara" implementation at a certain factory. At this factory, there was a concern about wanting to lower humidity further, but they could not increase the cooling and heating sources, and there was no infrastructure for reheat. With the introduction of our product, humidity has decreased, and the touch monitor is easy to operate. We have received feedback that the moving air diagram is convenient as it allows for understanding the supply air conditions. 【EcoSara Features】 ■ Enhanced dehumidification capacity ■ No need to increase cooling and heating sources even with low humidity supply air ■ Reheat possible even without a boiler or steam pipes *For more details, please download the PDF or feel free to contact us.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
