Close Control Units

Close control air conditioning systems are essential for maintaining stable environmental conditions in data centres, server rooms and other mission-critical facilities. These environments demand constant temperature regulation, humidity control and air purity for 24 hours a day, 365 days a year.

At the centre of many precision cooling systems sits the condensing unit, enabling efficient heat rejection while delivering consistent performance. High-performance condensing units improve reliability, reduce energy consumption and maintain optimal cooling capacity across varying loads and floor-by-floor demands.

Unlike comfort air conditioning, close control systems must operate constantly 24/7, requiring high reliability and minimal power consumption. Johnson Controls designs advanced close control air conditioning solutions that combine durable condensing unit technology with intelligent airflow management to deliver dependable performance where downtime is not an option.

Engineered for Reliable and Efficient Operation

Johnson Controls knows that no two close control requirements are the same; this is why the YORK® range of custom close control units offers quiet, compact and energy-efficient equipment that can be configured to meet your needs.

By combining compact design, quiet operation and scalable capacity, Johnson Controls close control systems deliver performance you can trust across multi-floor and multi-site environments.
