Catalog excerpts

Air-cooled Temperature Control Unit SENQA 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. 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. The air-cooled TCU uses a fan type aircooled condenser to reject heat from the refrigeration cycle. Optional heater for additional warming capacity for subcooled samples. Local display provides quick operational snapshot. Model: SENQA Chilled Water Flowrate gpm (lpm) Std Heating Capacity BTU/hr (kw) Cooling Capacity¹ ¹Cooling capacity based upon 110°F (43°C) ambient air and 76°F (24°C) coolant setpoint, 60 Hz power. ²MCA = Minimum Circuit Ampacity; used for main power wire sizing (not including Aux. Heater). ³Cooling and heating capacity is reduced about 17% for 50 Hz power.
