Hot-Oil-Circulating Temperature Control UnitHot-oil unit will circulate and precisely control the temperature of oil flowing through your process. Maximum temperature is 450°F (232°C). The oil temperature is continuously monitored with one thermocouple located in the oil supply line, which relays any deviation from setpoint back to the controller. A three-phase, flanged, low-watt-density immersion heater heats process oil. Heaters are vertically mounted to eliminate bending and stress that could cause premature burn out and are electrically interlocked to prevent their operating if the pump is not running or if low oil pressure exists. A bypass circuit incorporated in the system ensures heater flooding if there is blockage in the process lines, thus eliminating the possibility of heater burnout.

Water ChillersManufactured for a range of industrial and commercial applications, water chillers provide a constant supply of chilled, recirculated water. Multi-compressor systems operate independently as required.
Chiller for Laboratory ApplicationsDesigned as a replacement for analytical processes using tap or site water, Model FE1100 has a compact design that allows it to be located directly under a laboratory bench. The temperature display is bright, clear LEDs to ease readings. Setpoint range is 41 to 86°F (5 to 30°C). The air-cooled chiller is designed to be used with condensers or any analytical system where constant cooling water is required.
Julabo USA Inc.
Thermal Control UnitsWater-cooled chillers are designed to remove heat from a process and discharge it to an auxiliary facility water supply such as a central chilled water system or cooling tower. The facility water source does not need to be temperature controlled, but water sources exceeding 95°F (35°C) may require special design features. Affinity thermal control units have a small footprint, modular design, and quiet operation, with capacities up to 100 kW.

Deep-Well Compact BathsConstant-temperature fluid baths can be used to calibrate thermometers and temperature sensors. The deep-well compact baths provide 18" (457 mm) of depth to accommodate liquid-in-glass thermometers and other long-stem thermometers. Four baths in this series cover temperatures from -112 to 149°F (-80 to 300°C). Stabilities over that range are from +/-0.005 to +/-0.015°C and uniformities to +/-0.007°C.
Hart Scientific Inc.
Precision ChillersOffered in a range of configurations such as one-, two- or three-channel chillers, system can be supplied with air- or water-cooled condensers. With a temperature range of -94 to 392°F (-70 to 200°C) and stability of +/-0.1°C, the chillers have cooling capacity ranges from 1,700 to 256,000 BTU/hr (500 to 75,000 W) and up to three independent loops. Cooling fluid types include water, deionized water, synthetic fluids, ethanol, ethylene glycol or propylene glycol/water mixtures, and mineral oil, or others as required. Embedded computer control monitors critical system functions and controls refrigerant valves. Built-in self-diagnostics test for critical functions such as refrigerant temperatures, voltages and sensors.
Central Chillers Employ Rotational CompressionRS Series employs rotational compression technology with up to 50 percent fewer moving parts than reciprocating compressors. In sizes from 60 to 195 ton capacity, the central chillers utilize semi-hermetically sealed screw compressors. Up to 100 tons, compressors are matched to brazed plate evaporators; from 115 to 195 tons, they match to shell-and-tube evaporators. The screw compressors use R-134a, a non-CFC refrigerant providing energy efficiency increases of up to 12 percent.
