Released a video of the Silent Vacuum Drainage System.

The Silent Vacuum Drainage System solves your drainage problems!

The Silent Vacuum Drainage System is... When installing toilets or similar facilities in a basement, it is common to have a sewage tank and use a sewage pump for a pressurized system. However, a minimal amount of sewage often remains in the tank, leading to unpleasant odors. Additionally, when trying to install toilets or water facilities in existing buildings, it can be difficult to ensure proper usage conditions and the slope of the drainage pipes on lower floors, which may lead to abandonment of the project. To address these issues, a vacuum-based drainage system has been devised as an alternative to the pressurized system. However, many systems apply a vacuum sewage system that uses lift-up support and gas-liquid mixed suction, which has caused problems with noise and vibration. This system is a Silent Vacuum Drainage System that resolves noise and vibration issues by using a method that does not involve air suction. Model demonstrations are available for viewing.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when leaving the parking lot in my car..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Departure Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel including the controller and switching power supply (24V) is required when using the departure warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

The "HM-S6" is an embedded park sensor that detects vehicles through changes in magnetic flux and responds to various situations from passing to stationary vehicles. It can be used for the opening and closing of input doors at waste treatment plants, as well as for gates that vehicles pass through and outdoor parking applications. It can also be installed on rebar and steel plates. 【Features】 ■ Resistant to the effects of natural environments such as rain, snow, temperature changes, and geomagnetism ■ Protection rating IP68 reduces the risk of water ingress ■ Ten times the load capacity compared to conventional embedded park sensors (based on our comparison) ■ Can distinguish between vehicles even when they pass continuously ■ Can be installed on rebar and steel plates *For more details, please refer to the PDF document or feel free to contact us.

We will be exhibiting at the 2025 Autumn Conference of the Japan Society of Fisheries Science, a public interest incorporated association. We will showcase examples such as fishery environment monitoring, distribution surveys of sea urchins, which are one of the causes of coastal degradation, and the underwater time-lapse cameras that are active in monitoring damage in aquaculture sites. Additionally, we will introduce kits for collecting dead fish in aquaculture sites and sediment sampling kits that can be attached to underwater drones. Please feel free to ask the booth staff about new graduate recruitment and mid-career hiring for the 2027 fiscal year. We look forward to seeing you there. Date: September 24 (Wednesday) to September 27 (Saturday), 2025 Location: Hiroshima University, Higashi-Hiroshima Campus, Faculty of Biological Production (Higashi-Hiroshima City, Hiroshima Prefecture)
