Accelerating the Deployment of Next‑Generation Waste‑Heat Utilization Solutions for Data Centers
POLASTECH Inc. (Headquarters: Chiyoda‑ku, Tokyo; CEO: Hiroyuki Kakiuchi), a developer and manufacturer of Adsorption Heat Pumps (AHP) and the high‑performance zeolite material AQSOA®, is pleased to announce that it has raised 140 million yen in its Seed 2 round through a third‑party allocation of S2 preferred shares. The round was led by KRAFTIA Innovation Fund (operated by Spiral Innovation Partners), Tokai R&D No.1 Investment LPS (operated by Central Japan Innovation Capital, CJIC), and Shibata Welding Works Co., Ltd.
Business Background & Target Market
Toward a society without waste heat by 2050
POLASTECH is a deep‑tech company aiming to revolutionize cooling energy in data centers and industrial sectors. With the rapid expansion of generative AI, global data‑center electricity consumption continues to rise. Cooling systems are shifting from air cooling to liquid cooling, and the resulting waste hot water is expected to reach 50–60°C, creating a large volume of low‑temperature waste heat that is currently underutilized. This unused waste heat contributes to increased cooling power consumption and limits improvements in PUE (Power Usage Effectiveness).
POLASTECH’s Adsorption Heat Pump (AHP) system directly utilizes this low‑temperature waste heat as its energy source. Unlike conventional electricity‑dependent cooling systems, AHP converts waste heat itself into cooling energy, enabling:
- Significant reduction in cooling electricity
- Improvement of PUE
- Re‑utilization of waste heat as a resource
- Contribution to decarbonization strategies
The system can also be integrated with liquid cooling and immersion cooling, making it a highly promising solution for next‑generation data‑center infrastructure.
POLASTECH will accelerate demonstration projects and co‑development with domestic and international data‑center operators, engineering firms, equipment manufacturers, and energy companies, expanding collaboration with a wide range of partners.
Use of Funds
The newly raised capital will be allocated to:
- Strengthening mass‑production capabilities for AQSOA®
- Development and commercialization of AHP systems for data centers
- Expansion of domestic and international demonstration tests and PoC projects
- Enhancement of business development and engineering teams
- Recruitment and preparation for overseas expansion, including U.S. market entry
By integrating advanced materials technology with system engineering, POLASTECH aims to drive structural transformation in energy‑intensive industries, starting with data centers.
