20 L oil bath circulator
The HNZXIB GYY-20L is a 20 L thermostatic circulator that operates as a water bath up to 99 °C or an oil bath up to 200 °C. It uses a sealed magnetic pump to deliver 20 to 25 L/min at 1.45 MPa cycling pressure. A 4.5 kW heater runs on 220 V 50/60 Hz supply drawing 10 A.
Replaces basic static baths
The unit upgrades from simple uncirculated baths by adding active circulation and digital temperature control. The jump is worth it when experiments need uniform temperature across a 20 L volume or when sealed magnetic pumping prevents vapour leaks. It does not suit buyers who need temperatures above 200 °C in oil mode.
220 V single-phase limit
The 220 V 10 A connection caps heating power at 4.5 kW, so heat-up speed is fixed by that supply. The sealed magnetic pump sets a practical flow ceiling of 25 L/min and 1.45 MPa pressure. The 20 L reservoir volume limits the maximum sample load per run.

Questions about this item
What bench space and power supply does the 20 L oil bath need?
The unit holds 20 L of fluid and draws 10 A at 220 V 50/60 Hz, so allow room for the reservoir plus clearance for the sealed magnetic pump and a dedicated 220 V circuit.
How is the circulator plumbed and what wiring mistake should be avoided?
Connect the inlet and outlet to your external loop, fill with oil or water, then wire the 220 V supply to a 10 A breaker; the common error is powering the 4.5 kW heater before the 20–25 L/min pump is primed.
Which components will need inspection or replacement over time?
The sealed magnetic pump, heating element and temperature sensor should be checked periodically; the pump circulates at 1.45 Mpa and the heater runs at 4.5 kW, so seals and element degradation are the typical wear points.
