Navigator® Water-cooled Screw Chiller

Model WWV

Navigator water-cooled screw chillers, from 120 to 300 tons, are engineered as a fully VFD-driven platform to meet building applications that aren't suited for traditional chillers. This water cooled chiller integrates variable volume ratio (VVR®) compressor technology to give you the advantage of a system that is quiet and adapts to real-time building demands for the most efficient and cost-saving operation possible. For mission critical cooling applications, Navigator's RapidRestore® option can restore power after an outage, and a fast-loading option can restore full load cooling before it's missed.

Variable Volume Ratio Technology (VVR)

Navigator’s performance is optimized for every condition and at every hour of the day with Variable Volume Ratio (VVR) technology. VVR compression technology senses the precise amount of lift needed and adjusts the compression ratio on the fly to deliver optimal efficiency, regardless of ambient temperature or time of day. With VVR technology, you don’t pay for over-compression, and get exactly the lift needed.

RapidRestore for Water Cooled Chiller

RapidRestore® Technology

Restore cooling and peace of mind in as fast as 35 seconds. A power loss could turn into a critical loss of cooling in mission critical facilities such as data centers, health care buildings, or manufacturing processes. In addition, the fast-loading option can restore full load cooling capacity in under 160 seconds. So you can restore critical cooling before it’s missed.

Screw chiller with high efficiencies

Higher Levels of Efficiency

Built on Daikin Applied innovation, the Navigator gives you the power of efficiencies that meet or exceed ASHRAE 90.1 - 2016 levels. With IPLVs as low as 0.36 kw/ton, Navigator single VFD-driven compressor brings new levels of performance to applications that aren’t suited to traditional centrifugal or magnetic bearing solutions.
