Case Study - 340 On The Park

We replaced a 2 million BTU tank heater system with 2,000 gallons of storage with four tankless Intellihot Units cascaded together to provide a system with a 4 million BTU capacity.

This resulted in significant energy savings in the 1st high rise condo building in Chicago to earn LEED certification.

Case Study - Lake Shore Drive Luxury Condo Building

When this 27 story Luxury Condo building needed to replace their outdated rooftop HVAC system, Althoff Industries offered options and budgetary assistance. The building chose to replace a water-cooled chiller system with a 70-ton air cooled chiller.

After a helicopter lift that closed Lake Shore Drive for 30 minutes, the new system was in place and ready to be connected. Meticulous planning resulted in a flawless installation and customer satisfaction.
