Top 5 Things You May Not Know About Chillers and Baths

1. In 1748, artificial refrigeration was demonstrated for the first time by William Cullen of Glasgow University, UK.

2. In 1851, the first ice-making machine was invented by John Gorrie. Ice baths quickly became a popular way of cooling reactions and other lab processes, and this low-tech technique is still frequently used today.

3. In 1921, the first centrifugal water chiller was patented by inventor Willis Carrier. Before this time, chillers used a reciprocating compressor to move the refrigerant through the system. The main part of a centrifugal chiller is the centrifugal compressor. The design of the first centrifugal compressor was similar to the centrifugal blades in a water pump.

4. During the 1900s, lab processes that required elevated temperatures tended to be heated directly over a flame, or conducted in a water bath which was itself heated directly. However, the number of naked flames used in labs at this time represented a major fire hazard, particularly as many of the solvents being heated were highly flammable. This problem was resolved in the 1930s by husband and wife team Glen and Ruth Morey, who invented the heating mantle, a reliable and non-flammable heating device with electric resistance wires woven into a fiberglass cloth sheath. The first heating mantle was sold in 1939.

5. In 1950, the first industrial chiller was designed for use in the plastics industry.

Top 6 Questions You Should Ask When Buying a Chiller or Bath

1. Does the product have any exclusive features? What sets it apart from other vendor’s chillers or baths?

2. Is the vendor ISO 9001 certified?

3. What refrigerants are used in the product? (This is applicable to chillers and refrigerated baths/circulators.)

4. Are the products energy efficient, environmentally friendly, and in compliance with RoHS guidelines? (No heavy metals used in printed circuit boards, etc.)

5. Can old/broken units be returned for disposal in an environmentally friendly manner? (Refrigerants reclaimed, metals and other materials recycled, etc.)

6. Does the company accept trade-ins and, if so, what happens to the old unit? (Should be disposed of properly.)
