CW-3000 Water Chiller for PwnCNC Spindle Kits & Systems

S&A Branded CW-3000 Water Chiller for PwnCNC Spindle Kits & Systems

Passive Cooling for Reliable Water-Cooled Spindle Performance

Keep your PwnCNC water-cooled spindle motor running cooler and more consistently with the CW-3000 Water Chiller. This passive cooling unit helps remove heat from recirculating coolant, supporting more stable spindle operation, longer spindle life, and improved reliability during carving sessions.

The CW-3000 is a simple and dependable cooling solution for customers running water-cooled spindle kits and systems who want an easy way to manage coolant temperature without moving to a more complex refrigerated chiller.

Key Features

• Designed for Water-Cooled Spindle Systems
  Ideal for use with PwnCNC water-cooled spindle motors and spindle kits.
• Passive Cooling Design
  Uses high-efficiency fan-based heat dissipation to help remove heat from circulating coolant.
• Alarm Output Port
  Includes a built-in alarm output that can be connected to supported CNC controllers for added monitoring and safety.
• Simple and Reliable Operation
  No compressor-based refrigeration system means fewer complexities while still providing meaningful cooling support for many spindle applications.
• Compact Standalone Unit
  Easy to place near your CNC machine as part of a dedicated water-cooling setup.

Important Notes About the CW-3000

• This is a passive chiller, not an active refrigerated chiller.
• Temperature is not user adjustable.
• Cooling performance depends on ambient room temperature, spindle load, coolant flow, and duty cycle.
• Best suited for customers who want a simple cooling solution for light to moderate spindle use.

Fitting & Tubing Note

Our latest batch of chillers includes 6mm press-in fittings. We include two 6mm black tubes that press into these fittings. These 6mm O.D. tubes can then be inserted into your 6mm I.D. Superthane or silicone tubing.

If you experience any leakage at the tubing connection, we recommend securing the tubing with a zip-tie for a tighter seal.

🔧 Hoses are not fully included for your complete coolant loop. Add Clear Tube by the foot if needed for your cooling setup.
