1 Replacement Rooftop 2009 Product Training

2 OVERVIEW History of Multizone
The multizone unit was very prevalent in the 1960’s and 1970s. They had the ability to heat and cool different spaces within a common building. These units were very energy inefficient. Many of the major manufacturers built multizone equipment like Nesbitt, Lennox, Trane, Carrier, Mammoth. Plus there were a few others who produced equipment. These units were very inefficient due to the components they used. Each manufacturer built there units little differently. Since these units are reaching the end of their life cycle, how do you replace the unit without a lot of field labor? Also, how does a customer get better efficiency?

3 How does RMZ help solve this issue?
The RMZ product matches the footprint of several manufacturers.

4 RMZ Business 18+ Model Types, 10 - 55 Tons Replacement Units
Schools are % of our sales Multizone, Vari-Zone New Construction Growth Potential is Great Single Zone VAV Make-up Air Air Handlers

5 Why Replace? Worn Out Equipment Most Existing Multizones 20+ Years
Reduce Maintenance Costs Inefficient Designs Improve Indoor Air Quality Increase Capacity Cure Sick Buildings

6 Why Direct Replacement?
Minimize Installation Costs Existing Curb And Ductwork Remains Limit Disruption To Occupants Nearly All Work Confined To Roof Reduced Down-time Installation Can Often Be Completed In One Day
