Regarding the supply issues of rigid polyvinyl chloride (PVC) manholes.

EPJ EPJ
[Proposal for Polyethylene Access Holes] We believe everyone is facing difficulties... “To contractors planning to use rigid PVC pipes with a diameter of 600mm” Due to the impact of the Middle East conflict on the supply of domestic PVC products, we hope that our polyethylene access holes, EP-Sleeve, can be of some assistance... * We have stock available only for the 600mm size within Tokyo. * Of course, we also offer cutting services.

Lightweight polyethylene pedestrian passage (pedestrian opening) "EP Sleeve"! Labor-saving!

High-density polyethylene pedestrian passage (pedestrian opening) "EP-Sleeve" - Lightweight, high strength, and a proposal for labor-saving! [Coming soon]

Polyethylene Personnel Access Hole (Personnel Access Port) EP-Sleeve In response to everyone's requests, we are excited to announce its upcoming release! ■ High Pressure Strength: The smooth double structure of the corrugated inner surface makes it resistant to impact and external pressure, providing excellent flat strength. ■ Lightweight Material: Compared to rigid PVC pipes, it is lightweight. It enhances transportation and work efficiency, contributing to "labor-saving" at construction sites. ■ Rust Resistant: Made of high-density polyethylene, it is safe and secure for installation in water areas! ■ Cold and Chemical Resistant: Compared to rigid PVC pipes, it is suitable for installation in extremely cold regions and shows no degradation against most chemicals. "Lightweight accelerates efficiency on site!" A material that combines high pressure strength with the lightweight that leads to direct workability. In particular, rigid PVC pipes weigh about 53 kg/m, while polyethylene sleeves weigh about 17 kg/m, showcasing an overwhelming weight difference! We guarantee a significant improvement in work efficiency at construction sites. Furthermore, it also reduces the burden on workers and lowers the risk of accidents, contributing to enhanced safety! *For details, please request a catalog from "Contact Us" or view the PDF data from "Download."

Shorten construction time with EP sleeves for construction sites!

Lightweight polyethylene personnel access EP sleeves support shortening construction timelines!

In the construction industry, shortening construction periods is a crucial issue directly linked to cost reduction and efficiency. In particular, the installation of access openings is one of the factors that affect the construction schedule due to the time and effort required. EP sleeves, being lightweight, facilitate transportation and installation, contributing to a reduction in work time. 【Usage Scenarios】 ◆ For access openings in water pit partitions of buildings and various structures! - Ensures high load-bearing performance with polyethylene pipes. - Reduces work burden with lightweight polyethylene sleeves. - Provides corrosion resistance measures in underground pits and water areas. 【Benefits of Implementation】 ◆ Proposals for labor and manpower savings! - Reduces the burden on workers - Cost reduction through shortened construction periods - Improved safety *For more details, please request a catalog through "Contact Us" or view the PDF data via "Download."

Measures for extending the lifespan of public facilities using non-corrosive polyethylene access holes "EP Sleeve".

Improvement of work efficiency with non-corrosive materials and polyethylene through-holes "EP sleeve," promoting the longevity plan for public facilities, etc.

Based on the Ministry of Land, Infrastructure, Transport and Tourism's "Basic Plan for the Longevity of Infrastructure (Bridges, Roads, Public Housing, etc.)," we aim to achieve both the longevity of infrastructure and labor-saving at construction sites as a "two birds with one stone." 【Proposed Projects】 - Public facilities (public congestion, infrastructure-related facilities, etc.) - Seismic isolation structure high-rise buildings 【Effects of Implementation】 - Longevity through non-corrosive sleeves - Improved work efficiency through labor-saving/lightweight materials - Total cost reduction (materials + construction costs) Polyethylene is a stable material that fundamentally does not use plasticizers, and its lifespan is approximately 30 to 50 years if not affected by ultraviolet rays. In contrast, PVC resin containing plasticizers begins to deteriorate in about 10 years, potentially leading to reduced flexibility and cracking. EP sleeves contribute to the longevity of construction and infrastructure. "'Lightweight' accelerates 'efficiency' on site!" A sleeve material that combines high pressure resistance and direct workability with "lightweight." In particular, compared to rigid PVC pipes weighing about 53 kg/m, EP sleeves weigh about 17 kg/m, ensuring a significant weight difference that guarantees improved work efficiency and labor-saving at construction sites. *For details, please request a catalog from "Contact Us" or view the PDF data from "Download."

[To the design office] Are you struggling to explain "safety" to the client using only drawings?

  • NEW
  • CATALOG

Are you struggling to explain "safety" to the client using just drawings? • The risks in blind spots are difficult to convey to the client through drawings alone. • Safety measures often become a target for cost reduction, making it hard to communicate their necessity. • There is a concern that the client might say, "It's more dangerous than I thought," after completion. Risks that are clear to design professionals are not easily understood intuitively by clients who are outside the field. This document is not just a simple explanation of sensor functions; it is a guide to visually explain "why sensors are necessary in those locations." It can be used directly as explanatory material for clients. Here are three key points for utilizing this document: 1. Visualization of Risks Blind spots during departure and contact risks within the site are illustrated clearly. 2. Clarification of Selection Criteria A comparison table outlines the differences between complex sensor types such as infrared, ultrasonic, and loop coils. 3. Diagram of System Configuration It illustrates not just the sensors alone, but how they are combined with rotating lights and control panels, providing practical assistance for electrical equipment design. Please make use of this to prevent "rework after completion" and "accident risks."

[Free Catalog Distribution] Measures for "Near Misses" in Nursing and Care Settings. Prevent tripping and disconnection with codes! Wireless Series Bed Exit Sensors Linked to Nurse Call Systems.

  • NEW
  • CATALOG

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors notify wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

Full and Empty Management (Medium to Large Scale)

Parking lot occupancy management vehicle detection sensor | Hotron Co., Ltd.

  • NEW
  • PRODUCT

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
