� Majority of end-users are still buying R-22 systems

� These systems will be rapidly phased-out!

� R-22 components and refrigerant costs will only increase

� Expect service refrigerant availability and cost issues

� Expect service compressor costs to climb

� Expect maintenance costs to rise

R134a – Smart for your customer

� Specify R134a screw air conditioning systems

� Change from R-22 is the law

� R134a products are available and proven

� Cost of R-22 chiller will increase

� All major OEMs already made the change to R134a

� Invest in R134a high efficiency systems vs. R22

� +12% full-load efficiency for peak loads

� +29% part-load efficiency (IPLV) for normal operating

conditions

� Think “Lifecycle Considerations”–Total Cost Of Ownership,

Installed Cost, Operating Costs (Efficiency), Maintenance / Service

Costs, Refrigerant and Component availability

14New-CSW-Series

R134a – Smart for your business

� Clearly position you and your business as the experts in the HCFC phase-out in your geographical area or served

market segment

� Help your customers make sound, long-term decisions to

reduce future maintenance and energy costs

� Other benefits for your business by switching to R-134a

� Training and preparation of installation and service crews is

much better than last minute rush to convert

� Eliminate confusion on new installation components,

installation and service practices

� Secure incremental business opportunities with Green

Buildings

� Build an environmentally responsible image
