Trends driving the retrofit market
●Facility managers are
●Striving to reduce energy consumption/reduce costs
●Partnering with mechanical installation/service contractors
●Finding ways to decrease buildings total operating and energy
costs
●Lack of capital for large HVAC/R equipment replacement projects
●Remote energy monitoring and equipment control for LEED building
certifications
●Tax incentives and utility rebates are available but difficult to
understand and obtain by the facility Managers
●Energy projects require a 5 year ROI or less or positive cash flow to
be considered

Why apply Floating High (Head) Pressure Control
● Reduces Compressor Lift
● Saves energy
● Optimizes the head pressure per outside air temperature and load
● Take advantage of lower ambient design temperatures
(Which is about 95% of the time)
● Stabilizes the head pressure
● Minimize compressor short-cycling
during low ambient conditions.
● Reduces condenser fan noise
● Extends the useful life of the chiller
