Low-cost, chilled water supply reduces water consumption to zero. Manufacturer says that its own calculations show that in a working week (40 hours a week), the unit saves approximately 48,000 L of water. Temperature range is -20°C to +40°C and cooling capacity is 300 watts at 15°C. Suitable for cooling reaction blocks, vapour traps, vacuum pump condensers, rotary evaporators or heat exchangers, and supplies predictable and correct pressure, flow and temperature to applications resulting in tangible process efficiencies. Because its internal volume is only 2 L, it eliminates the risk of flooding in the laboratory, allowing processes to be run unattended.
