Recirculating Chiller DLSB-5/20 -20°C to RT 6.8L (CAT#: STEM-LT-1127-ZJF)

The Recirculating Chiller Series is designed for reliable and accurate temperature control in various applications. Each unit uses a fully closed compressor system with a cooling coil and circulation pump to deliver consistent cooling performance. The chillers are compatible with rotary evaporators, reaction kettles, and condensers, offering both direct and indirect cooling options. The compact CCA-420 is ideal for small setups, while the DLSB-5/20 and DLSB-20/40 provide larger capacities and higher cooling power for demanding laboratory or industrial processes.
