Cooling Water Circulator 16L Overview
The Cooling Water Circulator 16L (model CF802A) from Yamato Scientific is a refrigerated recirculating water circulator offering a 16 L capacity and a setting range of -20°C to 30°C. LabSupplies.com, an authorized dealer, supplies this closed-circulation cooler for labs that must hold process temperatures without a heating function.
A stainless steel water bath and stainless steel cooling coil resist corrosion across roughly 15.5 L of internal volume. The R410A air-cooled refrigeration system delivers about 1320 W of cooling at 10°C, while a Pt100Ω sensor and ON-OFF refrigeration control hold ±1.0°C accuracy. One unit can feed up to four rotary evaporators through a single rear circulation line.
Power comes from a single-phase AC115V, 15 A supply with plug. Bench footprint measures 340 × 370 × 838 mm, and the circulator weighs approximately 44 kg. Country of origin is China. Included accessories cover a 1 m condensation drain hose, two hose clamps, two hose nozzles, and a spare 2 A service-outlet fuse.
Key Features

- Stainless steel construction: stainless steel water bath and stainless steel cooling coil for durable, corrosion-resistant circulation.
- Multi-evaporator support: connects up to four rotary evaporators from a single rear-panel circulation line with a one-touch swivel L-type connector and flow-rate valve.
- Digital control: white LED display with key entry, 1°C resolution, Pt100Ω sensor, and refrigeration ON-OFF temperature control.
- Comprehensive safety suite: overcurrent ELCB, sensor-failure detection, upper/lower temperature limit alerts, high-pressure cutoff, fan and pump protection, and refrigerator-protection delay timer.
- Flow capability: maximum flow rate near 14 L/min and maximum head of roughly 14.3 m using tap water or anti-freeze solution above 10°C.
How to Choose the Right Circulator / Chiller
Matching a recirculating chiller to your workflow means weighing thermal load, fluid delivery, and site power before issuing a PO. Review these axes against the CF802A specifications.
- Cooling capacity: confirm the wattage your application removes at the target temperature; the CF802A provides about 1320 W at 10°C and 700 W at -10°C.
- Temperature range: verify the low-end setpoint your process needs. This unit sets from -20°C to 30°C and has no heating function.
- Flow and head: size pump output to your loop length and lift; here flow reaches roughly 14 L/min with a 14.3 m maximum head.
- Voltage and power: match circuit availability. The CF802A runs on single-phase AC115V at 15 A with a plug.
- Footprint and weight: plan bench or floor space for a 340 × 370 × 838 mm unit weighing about 44 kg.
- Safety devices: evaluate protection features such as ELCB, high-pressure cutoff, and limit alerts when the chiller runs unattended.
