Cooling Water Circulator 3.9L Overview
The Cooling Water Circulator 3.9L (Yamato Scientific CF303Y) is a refrigerated recirculating water circulator built for closed-loop cooling across a temperature setting range of -20°C to 30°C. Sold by LabSupplies.com, authorized dealer, this 3.9 L unit delivers roughly 450 W of cooling capacity at 10°C with ±1.0°C control accuracy at or above freezing.
CF303Y runs on single-phase AC115V at 6.8 A, while the CF313Y variant covers 220V installations. Its slim 205 × 396 × 535 mm footprint installs on or below a laboratory bench, and the unit weighs roughly 30 kg. Country of origin is China. Each circulator ships with a 1 m condensation drain hose, two hose clamps, and two hose nozzles.
Key Features
- Refrigerated cooling range: setting range of -20°C to 30°C with no heating function, delivering ~450 W at 10°C and ~330 W at -10°C.
- Digital control: Pt100Ω sensor with white LED display, key entry, and 1°C resolution under refrigeration ON-OFF control.
- One-touch connection: rear top-panel swivel L-type connector accepts a 10 mm OD hard tube or 9 mm ID flexible hose on a single line.
- R452A air-cooled system: 450 W air-cooled refrigeration with up to ~10 L/min flow and ~5.7 m maximum head.
- Layered safety devices: overcurrent ELCB, sensor-failure detection, upper/lower temperature limit alerts, refrigerator high-pressure cutoff, fan and pump protection, and a refrigerator-protection delay timer.

Frequently Asked Questions
What temperature range does the CF303Y cover?
The CF303Y sets between -20°C and 30°C with no heating function. Control accuracy is ±1.0°C at or above 0°C and ±1.5°C below 0°C, with cooling capacity around 450 W at 10°C and 330 W at -10°C.
What is the bath capacity and how large is the unit?
The water bath holds about 3.9 L with a 3.5 L liquid volume. External dimensions are 205 × 396 × 535 mm (225 × 434 × 564 mm including protrusions), and the unit weighs roughly 30 kg for on-bench or under-bench installation.
What is the difference between CF303Y and CF313Y?
Voltage is the only difference. CF303Y runs on single-phase AC115V at 6.8 A, while CF313Y is the 220V version. Both share the same 3.9 L capacity, -20°C to 30°C range, and cooling performance.
What materials contact the circulating fluid?
The water bath is stainless steel and the cooling coil is stainless steel 304. The circulating medium is tap water, or an anti-freeze solution when operating below 10°C.
How does the chiller connect to my instrument?
A single circulation line exits the rear top panel through a one-touch swivel L-type connector. It accepts a 10 mm OD hard tube or a 9 mm ID flexible hose, and the unit is recommended for rotary evaporator condenser cooling.
What safety features are built into the circulator?
Protection includes an overcurrent ELCB, temperature sensor failure detection, upper and lower temperature limit alerts and errors, a refrigerator high-pressure cutoff switch, fan motor protection, circulation pump protection, and a refrigerator-protection delay timer.
Where is the Yamato CF303Y manufactured?
Yamato Scientific lists China as the country of origin for the CF303Y.
What refrigeration system does the Yamato CF303Y use?
The Yamato CF303Y uses air cooling / 450 W and R452A refrigerant.
