Patten CAT is a 4th generation Caterpillar sales and service organization that began back in 1933. Their relationship with Cambridge Engineering heating products started in 2005 when they purchased their first Cambridge S-Series unit to retrofit a less efficient heating system at their Oglesby, IL location. Fast forward 12 years later and Patten has over 25 Cambridge units heating 6 of their locations throughout the Chicagoland area. 
- Oglesby, IL – 5 Cambridge s-series units
- Wauconda - 2 Cambridge S-Series units
- Rockford – 5 Cambridge S-Series units
- Hammond – 4 Cambridge S-Series units
- Joliet – 1 Cambridge S-Series unit
- Elmhurst – 7 Cambridge S-Series units and 1 Cambridge M-Series unit
In the beginning the units were purchased to retrofit older less efficient heating units which were not as effective in heating their facilities. Today they have used the Cambridge units to not only retrofit their existing locations, with the latest retrofit qualify for NiCor gas energy efficiency rebate, but to heat their location in Wauconda, IL which was a new construction project. For Terry Flick, Patten’s facility manager, Cambridge is his go-to heating products for Patten facilities. According to Flick, “Cambridge units are long lasting and are economical enough for people to purchase. Whenever I have to update something I keep going back to Cambridge.” There are other benefits that Patten realizes from using Cambridge equipment. Since the units are a 100% outside air heating technology the units help provide a little positive pressurization for their buildings. This helps keep the cold air out and improves the indoor air quality for their employees during the winter heating months. As Flick points out, “even on a zero-degree day the units still provide a 160-degree Fahrenheit discharge temperature which keeps our facilities nice and warm.” The other competitor’s units struggled to achieve a 60-degree discharge air temperatures when the outside temperature drops down to zero. And with their many Chicagoland locations they see quite a few zero degree days during the Chicago winters. Cambridge is honored to be the heating solution of choice for Patten CAT and we hope to continue our relationship with Patten for many years to come.
