Daihan -20°C+40°C Heavy-duty Refrigerated External Circulator/Chiller, 29Lit, 230V 60Hz(=SL.Chi0030) DH.CHI0030

The Daihan DH.CHI0030 is a heavy-duty refrigerated external circulator/chiller designed to provide controlled cooling and circulation for laboratory evaporators, reactors and external cooling loops. It operates over a temperature range of -20°C to +40°C and supplies chilled fluid for applications requiring stable temperature control with circulation and pumping capability. Typical use cases include supporting rotary evaporators and other 10–30 L laboratory vessels that require external temperature regulation and recirculation.

Key Features:

• Temperature range: -20°C to +40°C, stability ±0.2°C (at 15°C)
• Cooling fluid capacity: 29 L (maximum fill volume)
• Power: 230 V, 60 Hz (single-phase)
• Pump performance: max flow 20–30 L/min, max pressure 3.3 bar, max lift 27 m
• Cooling capacity: 2.8 kW (@ +20°C), 1.3 kW (@ 0°C), 0.45 kW (@ -20°C)
• Fluid inlet/outlet connector: ISO RC 1/2" (AG 1/2") stainless steel
• Top opening (lid) diameter: Ø100 mm

Advantages:

• Wide temperature range and tight stability support processes that need both deep cooling and moderate heating within one unit.
• Integrated high-performance pump delivers sufficient flow and pressure for external evaporators and circulation loops up to 30 L.
• Stainless-steel wetted parts and robust construction enhance corrosion resistance and durability in laboratory environments.
• Compact 29 L bath volume balances capacity for medium-sized evaporators while minimizing required footprint and fluid usage.
