Liquid to Air

Cooling Solutions

Our Liquid to Air cooling solutions are ideal for medium to large data centers requiring reliable, energy-efficient cooling with easy maintenance access.

The In-Row Coolant Distribution Unit (CDU) is designed for high-efficiency cooling with a capacity of 90-240kW at a ΔT 20°C. Its modular, redundant design allows for continuous operation even during maintenance, ensuring optimal performance and uptime.

Key Features

Quick and easy installation

The system features clamp-style piping interfaces available through top or bottom connection, as well as cam-type electrical plugs for flexibility and quickness of installation. 

Comprehensive monitoring

The CDU offers real-time monitoring of operating parameters, through a 7" touchscreen HMI, as well as multiple communication protocols available for remote monitoring.

N+1 Design

The CDU is designed with reliability and uptime in mind. With redundant pump, fans, power feeds and filters, the unit allows for hot-swap components and maximum uptime.
