10L Refrigeration Heating Circulator

The HNZXIB GDX-10/10 is a 10L laboratory circulator that combines refrigeration and heating in one sealed unit. It serves researchers who need continuous temperature control from -10°C to 199°C without changing bath fluids. The closed-loop design prevents vapour or oil mist from entering the workspace.

Upgrade from separate chillers and oil baths

This integrated machine replaces a low-temperature cooling pump and a high-temperature oil bath with a single device. The jump is worth it when bench space is limited and when switching between cooling and heating cycles must be fast. A large heat-exchange area cuts fluid volume and shortens ramp times.

Limits of the sealed circulation system

The expansion vessel stays below 60°C regardless of the loop temperature, so the heat-transfer fluid sees a wide operating range without degradation. No water vapour is absorbed at low temperatures and no oil mist forms at high temperatures. The fixed 10L capacity sets the maximum bath volume for any single experiment.

Questions about this item

What bench space and clearance does the 10L circulator need for the expansion vessel and sealed loop?

The closed system includes an expansion vessel that stays below 60 °C and is mechanically connected but not part of the liquid loop, so allow room for the vessel and insulated piping around the 10L bath.

Which connections must be made first when installing the integrated chiller and heated bath?

Connect the sealed circulation loop and expansion vessel before powering on; the self-diagnosis and overload protections only engage once the closed circuit is complete and the heat-transfer oil is filled.

How often should the heat-transfer oil be checked or replaced in the sealed circulation loop?

Because the loop is closed and the expansion vessel remains under 60 °C, oil degradation is minimal; inspect oil condition annually and replace only if contamination or viscosity change is detected.
