The Isotech Model 18233 Water Triple Point Maintenance Bath is not an adaptation of general-purpose equipment, but is specifically designed to maintain and safeguard one to four Water Triple Point Cells. Cooling is accomplished by efficient solid-state Peltier chilling modules, powered so that the rate of temperature change is very small. Solid state cooling ensures minimal power consumption, silent operation and no vibration.
Safety is provided by both electrical safety circuits and passively by the physics of ice. If the Peltier chillers become too cold, the first ice which forms is on the water tank surfaces directly in contact with the chillers, effectively inhibiting further rapid transfer of freezing to the bath water.
