RMR® modular cooling units deliver reliable temperature control for NEMA Type 12 enclosures, keeping internal components at optimal operating conditions. The closed‑loop design isolates the conditioned air from external contaminants, ensuring a clean environment for sensitive equipment. By using an HFC‑free refrigerant, these units support sustainability goals while maintaining high performance. The modular architecture allows flexible installation as either side‑mount or front‑mount units, adapting to a variety of enclosure layouts. Wide condenser fin spacing reduces particulate buildup, extending service life and minimizing maintenance downtime. Hermetically sealed compressors prevent refrigerant loss, providing long‑term reliability in demanding settings. Airflow is optimized with a backward‑curve impeller fan that balances pressure and volume, enhancing heat removal efficiency. Condensate is actively evaporated and directed to a dedicated drain port, eliminating moisture accumulation that could harm electronics. This comprehensive approach ensures consistent cooling even in high‑temperature environments. RMR® modular cooling units are engineered for seamless integration with CPI's broader thermal management portfolio, enabling coordinated cooling strategies across entire data‑center or industrial installations. The units complement aisle containment and liquid‑cooling solutions, offering a scalable path to higher density deployments. Their design supports rapid customization, aligning with CPI's commitment to global availability and rapid product adaptation. Choosing RMR® modular cooling units helps organizations reduce overall cooling costs while protecting critical infrastructure. The units' energy‑efficient operation contributes to lower power usage effectiveness (PUE) metrics, supporting sustainability initiatives. Partnering with CPI ensures access to expert consultation and worldwide distributor support for a successful implementation.
