(QTY 2) DLSB-60/80 Ultra-Low Temperature Recirculating Chiller, −80°C, 18 kW

DLSB-60/80 Ultra-Low Temperature Recirculating Chiller, −80°C, 18 kW 

This is a high-capacity cascade chiller that pulls coolant down to −80°C for deep ethanol winterization, cryo ethanol extraction, jacketed reactors, rotary evaporators, condensers and cold traps. The two-stage refrigeration system (R404A high stage, R23 low stage) gives up to 18 kW of cooling near room temperature and still 1.1 kW at −80°C. That’s enough for large jacketed vessels and fast solvent pull-downs. The pump moves 35 L/min with 12 m of lift, so it can push coolant through long hose runs and multiple condensers. It’s built on a heavy floor-standing frame, 617 lb.
