The Buyer Decision
When you're shopping for commercial or industrial refrigeration equipment, a water chiller often sits at the center of the setup. It keeps laser tubes, lab-grade water baths, and other heat-generating machinery at the right temperature. The challenge is choosing between a brand-new chiller with clear specifications and a used unit from a specific S&A model family. Here, the VEVOR CW-3000 and the S&A CW-5200DH represent two different ways to solve the same problem.
Quick Verdict
If you want a new air-cooled chiller with a published tank capacity, flow rate, and port size, the VEVOR CW-3000 is the more straightforward buy at its lower listed price. If you'd rather have an S&A-branded unit specifically described for laboratory and industrial cooling, the used CW-5200DH is the one to weigh.

Where Each Product Wins
Where the VEVOR CW-3000 Wins
- Comes as a new unit with a lower listed price.
- Published specs include a 12 L tank, a 12 L/min max flow, and a φ 0.4 in/10 mm inlet/outlet port.
- Air-cooled with a built-in cooling fan, plus a visual water level that makes refill timing easy to see.
- Supports laser tubes up to 80W.
Where the S&A CW-5200DH Wins
- Carries the S&A model and type identifiers: S&A CW-5200DH and CW-5200DH.
- Positioned for precise temperature control in water baths, circulators, and other cooling devices.
- Made in China, with a clear model designation for lab and industrial settings.
Product Notes
VEVOR Air-cooled Industrial Water Chiller CW-3000 12 L 12 L/min for Laser Tube
This chiller arrives new and brings a complete set of cooling numbers: a 12-liter tank, a 12 L/min maximum flow rate, and a cold water port diameter of φ 0.4 in/10 mm. It's air-cooled with a built-in fan, which keeps the design compact and suited to a single cooling requirement - the unit is designed for one cooling equipment item (Number of Cooling Equipment: 1). The main casing is carbon steel and aluminum alloy, and the visual water level lets you see at a glance when a refill is needed. The one limitation to weigh is the port size: at 10 mm, it's on the smaller side, so make sure your laser tube or process equipment can connect to it. With a lower listed price than the S&A unit, it's the choice that requires less cash up front.
S&A Genuine CW-5200DH Industrial Water Chiller
This used S&A unit is a different type of buy. It's intended for laboratory and industrial use, with precise temperature control for water baths, circulators, and other cooling devices. The model identifier, S&A CW-5200DH, and type CW-5200DH make it clear exactly which S&A CW-5200DH unit this is. It was made in China. The trade-off is that you're paying a higher listed price for a used unit rather than a new one. For buyers who want the S&A model line specifically for lab-style precision cooling, the CW-5200DH fits that role. For those who need a single, simple laser tube chiller, the higher price and used condition are things to weigh before committing.
Final Choice by Use Case
Choose the VEVOR CW-3000 if your priority is a new, air-cooled chiller with clearly listed specs - 12 L tank, 12 L/min flow, and a 10 mm port - and you want to keep the outlay closer to USD 149.90. Choose the S&A CW-5200DH if you need the S&A model design for laboratory or industrial water cooling and are comfortable with a used unit at USD 299.50.
