High-Rise Data Center Maintenance

About This Project

A customer moved their entire operation from downtown Chicago to two high-rise buildings in the suburbs of the city, and they neededed a service provider to maintain their data centers.


The new high-rise building towers are ice bank buildings. In this type of building, the chillers make ice in large underground vaults during the night when demand for electricity is very low, and then during the day, when demand for electricity is high, the ice is used as a cooling source. This process can significantly decrease costs because they are using less expensive off-peak electricity for cooling.

With this type of cooling system for their data center, our customer was in need of a knowledgeable mechanical contractor to provide the appropriate maintenance, repair and service.

Data Center Equipment Includes:

  • Two (2) Carrier Systems
  • 25 Liebert Systems
  • Two (2) Liebert Dry Cooler Pumps on Roof
  • Two (2) McQuay Centrifugal Chillers
  • One (1) Evapco Tower
  • Four (4) B&G Chill-Water Pumps
  • Six (6) Trane Chillers
  • Two (2) Air Technology System Units


Our customer selected Kroeschell as their service contractor of choice, and for the past 20 years, we have been providing full coverage maintenance and repair of their data center mechanical systems. Our contract covers full coverage quarterly service and emergency response.

Over the course of the contract, Kroeschell has provided such precise preventive maintenance on the equipment that in the 20 years of service, only two cooling systems needed to be replaced and only one additional rooftop cooling system for their UPS room needed to be installed.

Throughout the life of the contract, Kroeschell has always taken response time very seriously:

  • We respond to all emergency communications in 50% less time than the industry standard response time.
  • When an emergency call is made, the same Kroeschell technician conducts the maintenance and/or repair.

This has allowed Kroeschell to build a personal relationship with our customer, which has led to complete confidence in our work and total customer satisfaction.

Under our contract, we have implemented a customized maintenance schedule that meets the unique needs of our customer.  It requires our technicians to be accessible 24/7 and supports training to onsite personnel. We strongly believe in sharing knowledge so our customers become familiar with their own data center equipment. This allows them to recognize problems quickly, diagnosis them and even fix minor issues on their own.

We also take the time to recommend energy efficiency initiatives and make them aware of new technology or upgrades that will decrease energy costs. It is our objective to provide the best service possible.


Kroeschell has provided our customer with an extraordinary cost effective maintenance solution and remarkably high quality service for 20 years.

Our services provide:

  • Continuous data center uptime.
  • Energy efficient upgrades that provide government rebates and major cost savings.
  • Renowned emergency response time.
  • In-depth facility and equipment knowledge from our expert technicians.

Our relationship has grown over the course of two decades, and due to our remarkable customer service, Kroeschell now provides maintenance and repair service to other HVAC systems outside the data center.
