Reasons to reconsider "attic ventilation" before using the air conditioner.

セイホープロダクツ セイホープロダクツ 業務本部
The reason the air conditioning isn't working well might be due to the roof. With the ongoing extreme heat, it's easy to lower the air conditioning temperature, but the causes of "not cooling" and "high electricity bills" may actually lie in the "attic." Japan's summers are becoming increasingly severe each year, and many households are likely struggling with the heat, especially on the second floor. In fact, the source of that heat is the heat trapped in the "attic." [Table of Contents] ■ The attic can get as hot as nearly 70°C in midsummer! ■ First, let the "heat in the attic" escape outside! ■ You can feel the effects at night! ■ Installation takes just one day; now is the chance before summer hits full swing! ■ This summer, let's start with "attic ventilation." Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓

風之介かくはん24(追加用単体)無塗装01.jpg

Ventilation Series for the Shed: 'Kaze no Suke Kakuhan 24'

24-hour ventilation (strong/weak, switchable) type

High functionality and innovative design backed by data. A large high-volume type of Sirocco fan is adopted to more effectively stir the air under the floor and in the ceiling space. The high-volume air blows out in four directions. With a unique scroll shape that minimizes waste, it achieves about twice the wind reach distance compared to conventional types, with a diameter of about 9 meters (wind speed 0.5 m/s). The three-dimensional design with low air resistance and quiet operation smoothly draws in heavy, moisture-laden air. The body is made of lightweight and durable aluminum alloy, eliminating concerns about rust. The controller with a temperature sensor detects the temperature in the ceiling space and switches between strong and weak operation. The newly designed high-performance two-speed motor operates at high power when the ceiling temperature rises, effectively exhausting heat. It operates at low power when the temperature drops. 【Features】 ○ Effective for heat and condensation measures in attic spaces ○ Automatically operates by sensing temperature For more details, please contact us or download the catalog.

Released the Toilet Full Indicator System InfoLink.

  • NEW
  • OTHER

We will start providing the toilet occupancy display system InfoLink. It integrates and manages door opening and closing sensing data to display on digital signage. While protecting privacy, it aims to enhance user convenience and improve facility management efficiency. 【Features】 - Convenience: By visualizing the toilet usage status, users can easily see the availability at a glance, which helps improve user convenience. - Congestion Relief: Digital signage installed at the entrance of the toilet or in distant locations can display the congestion status, smoothly guiding users. It can also show the status of toilets on different floors or nearby, promoting the distribution of congestion. - Safety: Alerts can be issued if a toilet stall is occupied for an extended period. (Options available for 15 minutes, 30 minutes, or 45 minutes) This allows for quick responses to individuals who may become unwell inside the stall or to suspicious persons who may be hiding. - Efficiency: Toilet usage status can be obtained as log data. By understanding the differences in usage frequency by location, it can be utilized for optimizing cleaning plans and appropriate toilet expansion plans. (*Some optional services and plan-specific features are available. For details, please contact us below.)

We will make the "practical thinking skills" that cannot be seen in interviews, documents, and knowledge tests visible.

"Business Case Study" to Measure the "Practical Skills" of Job Candidates [Trial Version Available]

  • NEW
  • PRODUCT

The resume lists impressive qualifications, and during the interview, the candidate appears personable and seems to have ample experience. However, "how they actually perform after joining the company" cannot be known until the lid is lifted—do you not have such experiences? We will evaluate the "practical thinking skills" that are difficult to grasp through resumes and interviews by assessing candidates' essential abilities, such as their thinking skills, problem-solving abilities, and attitudes, through case studies that simulate situations close to actual work. ▼ For details, please download the catalog - Visualizing the "thinking ability" of job candidates: Business Case Studies [for recruitment selection] ■ Moving away from intuition and experience-based hiring Objectively grasping practical problem-solving abilities without bias towards interview impressions or backgrounds. ■ Measures against variability and early turnover after joining Confirming factors (thinking, judgment, planning) that create differences in outcomes and retention after joining during the selection stage, connecting to development plans. ■ Low barriers to implementation Start with a 30-minute experience to confirm the entire flow from upstream to downstream (problem discovery to solution presentation to feedback). * We can accommodate requests to optimize the implementation design based on difficulty, required time, and other factors.

Truck berth vehicle detection

It's not too late to address the "2024 Problem." Why not immediately reduce drivers' waiting times?

  • NEW
  • PRODUCT

Are you making progress on measures for the "2024 Problem"? The management of drivers' working hours is becoming stricter, and in the logistics field, reducing "waiting time for loading" has become an urgent issue. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability status, reducing unnecessary waiting and queuing, and shortening waiting times, thereby alleviating the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start taking measures against the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult us first.
