Why a Turbocor Retrofit? Efficiency is of utmost importance in today’s world of escalating utility costs and chillers are by far the biggest energy consumers in the building. However, replacing the chiller is not always the best option, especially when the mechanical equipment is difficult to reach with a crane or is below grade. The largest chiller efficiency gains are accomplished through compressor technologies and intelligent digital control. Retrofitting an existing chiller with Turbocor compressors can often show the best life-cycle return on investment.

Note: The Turbocor compressors are amazing. With only pumping background noise going from off to full load (close to 300 tons) there is no outright cues that the compressor is running – no noise, no vibration, nothing. If you’re not looking at readings telling you the compressor is running you wouldn’t believe it. Wow.
