water-cooled Temperature Control Unit SENQW Series Provides controlled temperature coolant for secondary coolers Cooling water at a precisely-controlled temperature with ± 1° F (0.5° C) accuracy. A temperature control unit (TCU) provides controlled temperature water (coolant) to a group of secondary sample coolers in order to ensure closely controlled sample temperatures. Self-contained with all necessary controls, pumping and refrigeration systems. Wide condenser cooling water temperature range: 55-105°F (13-41°C). Options available as low as 30°F or as high as 115°F (46°C). Optional heater for additional warming capacity for subcooled samples. Local display provides quick operational snapshot. Model: SENQW Sentry temperature control unit (TCU) systems are pre-designed, pre-piped packages available in sizes from 3 to 15 tons, air or water-cooled. All components are easily accessible for service. Each Sentry TCU system undergoes a factory “run-in” under a range of heat loads. Measurements are taken of critical parameters and recorded for future reference.
