On jobs in which sound levels are of major concern, can something be done to reduce the sound level of a 19EX or a 17EX chiller?

On each of these chillers, something can be done to reduce the overall sound levels. On the 19EX the sound level can be reduced by several dBA by applying an acoustic sound blanket that has been custom designed for this piece of equipment. On a 17EX there is also a custom-designed acoustic blanket, but, in addition, a low-noise motor is strongly recommended when significant sound reduction is the goal. Open motors such as TEWAC and WPI or WPII with acoustic baffles are examples of low-noise motors that are available through Carrier. Please contact your local Carrier salesperson for more details.
