In modern frozen carbonated beverage devices, there is a conventional refrigeration circuit with a capillary tube or thermostatic expansion valve and, usually, an air condenser.
3.
Pre-cooled engines avoid needing an air condenser because, unlike Liquid air cycle engines ( LACE ), pre-cooled engines cool the air without liquefying it.
4.
Cavendish also discovered the inductive capacity of dielectrics ( insulators ), and, as early as 1778, measured the specific inductive capacity for beeswax and other substances by comparison with an air condenser.
5.
Proper refrigeration maintenance of a pumpable ice maker will extend its life, and routine maintenance can reduce the probability of an emergency service caused by major component failure, such as of a refrigeration compressor or the fan motor of the air condenser due to a dirty coil, and refrigerant leakage.

It provided radio components such as a Precision Variable Air Condenser ( $ 25.00 ), a Decade Resistance Box ( $ 19.00 ), a Precision Variable Inductance ( $ 24.00 ), and an Absorption Wavemeter ( $ 60.00 ), and quickly profited from strong demand for military radios during World War I and the subsequent radio broadcasting boom.
