Cooling circulator Chiller LX -0400

Cooling Circulator Chiller LX-0400

Late Friday afternoon, your exothermic Grignard reaction starts climbing past safe limits despite the water bath running at full tap flow. You need sub-zero cooling capacity, not ambient water that barely touches 15°C in winter. Real refrigerated circulation makes the difference between controlled synthesis and weekend cleanup.

Precision Temperature Management in the LX-0400 Refrigerated Circulation System

Operating range spans -25°C to +40°C with 400W cooling capacity at the compressor, though real-world performance drops to around 280W when you're pushing -20°C setpoints. Temperature stability holds within ±0.5°C at setpoint, critical when you're running temperature-sensitive coupling reactions in your TOPT-3L jacketed glass reactor (double glass reactor) where a 2-degree swing ruins stereoselectivity. The 25-liter reservoir provides thermal mass that buffers against sudden load changes—connect your Glass Jacketed Reactor (Double Glass Reactor) TOPT-5L and watch setpoint recovery stay tight even during vigorous reflux conditions.

Laboratory-Grade Cooling Performance Beyond Standard Water Baths

• Pump delivers 20 L/min maximum flow through typical 3-5 meter tubing runs to jacketed vessels, maintaining turbulent flow for efficient heat exchange at the glass surface
• R449a refrigerant chemistry replaces older formulations with 63% lower global warming potential while keeping thermodynamic efficiency comparable to legacy systems
• Startup time runs 35-40 minutes from ambient to -20°C with an empty bath—plan accordingly when your TOPT-1L Glass Jacketed Reactor (Double glass reactor) needs pre-cooling before charging reagents
• Power consumption fluctuates 800-1200W depending on setpoint differential and how hard the compressor works against ambient conditions

Advanced Circulation Technology for Consistent Heat Exchange

Ambient temperature affects everything. Run this chiller in a room above 28°C and cooling capacity degrades noticeably—the compressor cycles harder, runtime increases, and you might not reach -20°C under full load. Install in climate-controlled spaces when targeting temperatures below -15°C consistently. Noise stays under 55 dB at one meter distance, quieter than the Vacuum pump SHB-B95 or Vacuum pump SHB-III running on the same bench. Pair with external heat exchangers when circulating beyond 8 meters or feeding multiple instruments simultaneously—the pump has flow capacity but pressure drop accumulates in long tubing runs.

Integration with Rotary Evaporators and Reaction Vessels

Direct connection to reactor jacket inlets handles exothermic reactions where heat generation outpaces passive cooling methods. One organic chemist runs cryogenic lithiation at -20°C by circulating through a TOPT-1L Glass Jacketed Reactor (Double glass reactor), maintaining temperature while adding organolithium dropwise. Condenser cooling for rotovaps works particularly well for solvents boiling above 40°C—tap water struggles with efficiency, but refrigerated circulation at 5°C recovers solvent cleanly. Analytical labs use these chillers for HPLC column compartments, GC detector blocks, and spectroscopy sample holders requiring sub-ambient stability beyond what Peltier elements provide. Footprint measures 400×600×1150mm, fitting beside benchtop reactors or floor-mounted for shared circulation across multiple instruments.
