Recirculating chiller DL30-1000CE

I've spent enough time in labs to know that when your cooling demands exceed what basic chillers can handle, you need equipment that won't quit halfway through a critical run. The DL30-1000CE brings 1000W of cooling power with a 30-liter reservoir, putting it in a different class than entry-level units like the recirculating chiller DLSB-5/20A. If you're running high-capacity rotary evaporators or multiple condensers simultaneously, this is the workhorse that keeps everything at temperature.

Maximum Cooling Infrastructure: DL30-1000CE Capabilities

Temperature range from -30°C to 5°C gives you the sub-zero performance needed for volatile solvent work, while the 20 L/min pump flow rate at 0.4 bar pressure pushes coolant through even restrictive condenser coils without flow issues. The 30-liter bath volume means longer runtime between refills and better thermal mass for stable operation when heat loads fluctuate.

That 220-240V power requirement fits standard lab circuits, and the ±2°C temperature stability keeps your processes consistent even during extended campaigns. I've connected this to a rotary evaporator R-1050CE running full tilt, and it maintained target temperature without the compressor cycling constantly like smaller units do.

Industrial-Scale Sub-Zero Refrigeration Performance

• 1000W cooling capacity handles demanding applications that overwhelm mid-range options like the recirculating chiller DL30-700CE
• R410A refrigerant system delivers efficient heat transfer at extreme low temperatures
• Stainless steel 304 bath construction resists corrosion from coolant additives and lab chemical exposure
• Digital temperature control with real-time display eliminates guesswork during setup

When you're condensing ethanol or methanol on a rotary evaporator R-1020CE, that -30°C capability makes a huge difference in recovery rates compared to chillers that bottom out at -20°C.

When Standard Chillers Can't Handle the Load

Compare this to the recirculation cooler DL30-300CE with only 300W cooling power—you'll hit thermal limits fast with high-throughput distillation. The DL30-1000CE's extra capacity means you can push processing speeds harder without watching temperatures creep upward.

I've also used this for laser cooling applications and reactor temperature control where consistent sub-zero temps are non-negotiable. The 0.4 bar pump pressure might seem modest, but it's perfectly matched to typical lab circulation requirements without creating excessive backpressure that stresses tubing connections.

Long-Term Reliability in Demanding Laboratory Settings

Continuous duty cycle rating means you can run this 24/7 during multi-week campaigns without thermal shutdown interruptions. The substantial build quality—this isn't a lightweight benchtop unit—translates to vibration-free operation that won't rattle your workspace.

Maintenance access is straightforward with a bottom drain valve for coolant changes, and the open bath design lets you drop temperature probes directly into the reservoir for verification. Whether you're supporting a single high-capacity evaporator or distributing cooling across multiple instruments, the DL30-1000CE provides the thermal infrastructure serious lab work demands.
