[Hashimoto Sogyo Mirai City Tokyo Exhibition] Solving Challenges in Machinery Rooms! Live Demonstration of the Industry's Smallest Class "Compact Filtration Device PRT-800" The science of filtration devices will once again be showcased at one of the largest exhibitions in the water supply, drainage, and sanitation equipment industry, "Hashimoto Sogyo Mirai City Tokyo"!! ■ Science Exhibition Overview ■ 【 Date 】 November 14 (Friday) and 15 (Saturday), 2025, 9:30 AM - 5:00 PM 【 Venue 】 Tokyo Big Sight, East Halls 7 and 8 【 Booth 】 7-B6: Science Booth At this exhibition, we will introduce a new product that addresses the significant challenge of "installation space constraints" in equipment renovations through a live demonstration. Our newly developed [Industry's Smallest Class Compact Filtration Device PRT-800] flexibly meets the needs for installation and renovation in narrow machinery rooms while maintaining high filtration performance. Additionally, the simultaneously exhibited [Bathtub Heat Retention Heat Pump: Bath Heapon] achieves a 40-70% reduction in bathtub heat retention costs compared to conventional heat sources, strongly supporting energy savings. If you are struggling with "narrow machinery rooms" or "cost reduction," please visit the Science Booth (7-B6)! Our representatives will be available to discuss your specific inquiries.
