【CAD Data Creation】We create indoor piping diagrams from residential blueprints and deliver pre-cut resin pipes and fittings to the construction site as needed. This frees you from the tasks of material picking and transportation to the site. In addition to reducing costs and labor burden, it also improves traceability by storing the drawings after construction.

We will create the indoor water supply and hot water supply (header method) piping equipment drawings on your behalf, freeing you from the hassle of the work. We will precut and deliver only the necessary amount directly to the site when needed.

The "SEDIA Resin Pipe/Fitting Pack" delivers pre-cut resin pipes and fittings along with indoor piping diagrams and CAD data created from residential blueprints. This is an optional service from Watanabe Pipe that we encourage companies facing challenges in: - Quality improvement - Reducing construction work - Cost reduction It not only reduces transportation work to the construction site but also frees you from the task of picking out materials, contributing to cost and workload reduction. After construction, we will store the design drawings for 10 years. 【Features】 - Piping diagrams created using the header method/polybutene pipes - Shipped by total roll count, eliminating the need for excess inventory - Easy ordering (contact our service center) - Examples of time savings of 75 minutes per site ★ Significantly reduces the risk of leaks ★ Easy maintenance and inspection ★ Minimal flow changes even during simultaneous use Please try our confident service that greatly improves both the quality and efficiency of construction using Bridgestone's "Push Master." *For more details, please refer to the materials. Feel free to contact us with any inquiries.

■What is Polybutene? It is a synthetic resin produced by polymerizing "butene-1," featuring a helical structure with ethyl groups in the side chains. With a molecular weight of approximately 1.2 million, it is very large and exhibits excellent heat creep resistance and stress crack resistance. ★Excellent Durability Due to its superior heat creep characteristics, there is almost no reduction in strength even when used at high temperatures for extended periods. ★Excellent Insulation and Refrigeration Properties With a low thermal conductivity, it excels in maintaining the temperature of fluids within the pipe. ★Hygienic, Safe, Clean, and Reliable This safe pipe does not cause water quality contamination due to rust, and it is less prone to issues like red water or scale buildup. ★Lightweight, Flexible, and Easy to Install Being lightweight and flexible, along with its long pipe lengths, makes it easy to handle, and since threading or machining is unnecessary, installation is simple.

Regarding the "Automatic Stop Function after 10 Years" Automatic stop has been implemented in products manufactured from 2015 onwards. ■ Overview of Inspection Period Notification Function The dedicated controllers and timers for underfloor and attic ventilation fans sold since 2015 are equipped with the safety function mentioned on the left. Starting from November 2025, the automatic stop function will be activated sequentially for products manufactured in 2015. ■ Response Procedure at the Time of Automatic Stop It is expected that customers will contact the sales and installation stores. We ask that sales and installation stores respond according to the following procedures: 1. Conduct a safety inspection based on the "Underfloor and Attic Ventilation Fan Inspection Checklist." * Please ensure to check for looseness and retighten the connections of the controller and timer. If any liquids such as water, oil, or detergent have come into contact, the internal components may corrode, leading to fire hazards; therefore, replacement of the main unit is necessary. 2. If there are no issues, press and hold the set button to restart the operation. ■ Start of Shipment for Controllers/Timers with Inspection Period Notification Function For details regarding the shipment history of timers, please contact our company’s sales representative or quality control department.

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.

We have introduced Majesta Fragrance at a bar located in Roppongi, enhancing the ambiance with scent. The first impression of a store is greatly influenced by the "fragrance" experienced the moment you enter. The model we introduced is the "MF-01," which costs 8,800 yen per month. Its cylindrical and slim design allows the diffuser to blend seamlessly with the bar's stylish interior without being intrusive. It takes up little space and elevates the adult atmosphere with a high-quality scent. It is chosen by establishments that prioritize the quality of their space, from restaurants to nightlife venues.
