APC 0M-71591 CW Hot Water Reheat, 123-140kW

Ensure reliable uptime for critical power and security systems by keeping batteries at the ideal operating temperature. The APC by Schneider Electric 0M-71591 CW Hot Water Reheat is a purpose-built accessory for battery cartridges and UPS cooling systems, providing controlled reheating for installations in the 123–140kW range. By using hot water reheat to avoid overcooling and condensation, this unit helps prevent premature battery degradation and reduces the risk of thermal cycling that can shorten service life.

Designed for data centers, security rooms and surveillance monitoring hubs, the 0M-71591 integrates cleanly with APC infrastructure to support continuous operation of UPS, monitoring and access-control equipment. Key specifications such as the model number (0M-71591), hot water reheat capability and the 123–140kW power range ensure compatibility with medium-to-large cooling loops and battery cartridge banks. The result is improved reliability for security and surveillance deployments, simplified maintenance, and lower total cost of ownership. Contact your APC by Schneider Electric representative to specify the 0M-71591 for your battery cartridge and UPS cooling application, or add it to your next infrastructure upgrade.
