by Brianna Crandall — February 17, 2017 — Vertiv, formerly Emerson Network Power, announced in recent weeks the availability of a mobile app to monitor and control two of its data center cooling systems, and introduced a new software system to improve cooling system reliability. Vertiv designs, builds and services critical infrastructure that enables vital applications for data centers, communication networks, and commercial and industrial facilities.
iCOM CMS Monitoring and Control System
Earlier, Vertiv announced that two of its most popular Liebert cooling systems for small information technology (IT) spaces are now available with the iCOM CMS Monitoring and Control System that enables remote monitoring, management and alarm troubleshooting for IT managers and service technicians.
iCOM CMS is now available in North America for the Liebert SRC Mini-Split Cooling System and Liebert Mini-Mate2 Ceiling Mounted Precision Cooling System.
iCOM CMS provides enhanced protection, visibility and control for small IT spaces that are increasingly used for edge computing and have become critical links to the cloud. iCOM CMS operates through the industry’s first Internet of Things (IoT) mobile app, the Web or building management systems (BMS), allowing IT managers to view room and equipment conditions and alarm notifications, remotely manage cooling systems, and track the progress of troubleshooting and repair through automated workflow tracking.
The Liebert SRC is a high efficiency, easy-to-install mini-split air-conditioning system that provides cooling for server rooms, network closets and other small IT spaces. Offering 4.5kW-9kW cooling capacity, the Liebert SRC provides simple building management system connectivity and is less expensive and faster to deploy than ducted systems.
The Liebert Mini-Mate2 is a zero-footprint computer room cooling system for 7×24 temperature and humidity control. Offering 3.5-28kW cooling capacity, it installs above a dropped ceiling.
Monitoring and remote management are among the top three concerns facing North American IT professionals regarding the management of small IT spaces, according to the Vertiv 2016 Cooling the Edge Survey. Nearly half of the survey’s respondents said that these small spaces are mission critical, as they contribute to company revenues.

More recently, Vertiv introduced Liebert iCOM Autotuning, an adaptive intelligence and machine learning software system designed to improve cooling system reliability, increase efficiency and significantly extend system life, thereby providing the highest level of protection for mission-critical operations.
Liebert iCOM Autotuning is a feature of the Liebert iCOM-S thermal system control and is available for select Liebert data center cooling systems installed in North America. It was demonstrated at the International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo), January 30 – February 1 in Las Vegas.
Typical data center cooling systems have multiple control systems for individual mechanical components, such as chillers, CRAC units, economizers and others. These controls generally are not coordinated and often operate with conflicting performance, or “fight” each other, says Vertiv.
The traditional fix for this problem has been to manually tune component controls, a time-consuming and costly practice that might work for initial conditions but becomes ineffective as conditions change. Simply changing the controls to fine-tune one component often triggers oscillations of other components that had previously been stable, points out Vertiv.
Liebert iCOM Autotuning reportedly resolves this dilemma. It applies machine learning and advanced algorithms to regulate Liebert Direct Expansion (DX) compressors or chilled water valves in a way that brings the rest of the system components into balance and stabilizes airflow and temperature. For DX systems, that means harmonizing compressors, fans and condensers to eliminate costly short cycling. For chilled water systems, that means eliminating rapid fluctuations in valve positions, called “valve hunting,” to balance fan speeds, water temperature and flow rates.
The results are efficiency gains up to 15 percent, more stable air temperatures, and reduced wear and tear on compressors and chilled water valves, extending their lives by up to 20 percent, says the company.
