(spindle/guard clearance), either a 4 inch rod extension (part number BLM-4E) used with type A lab stand or an 18 inch rod replacement (part number VS-38) used with type S lab stand are available from Brookfield or an authorized dealer. *Included with 50Hz Models only. -
Page 4: General Description
Refrigeration is normally required for operation at temperatures below 40°C. However, refrigeration should not be used when the fluid temperature is above 55°C. Refrigeration should not be turned on when the ambient air temperature is above 32°C. Model Specifications TC-102D TC-202D TC-502D TC-602D Temperature Range Ambient +5°... -
Page 5: Pump Inlet And Outlet Connections
Pump Inlet and Outlet Connections The pump inlet and outlet ports are female ¼ inch NPT connections that permit use of barbed tubing adapters or hard plumbing fittings. ½ inch (13mm) ID tubing may also be slid over these connections and held in place with a hose clamp. -

The temperature control stability of a closed loop system is better at the external apparatus than in the Circulator reservoir (provided the control point of the apparatus represents a constant load and is well insulated). For example, if you circulate fluid through a viscometer at 50°C, the temperature variation observed in the Circulator reservoir may be ±0.2°C while the temperature variation in the viscometer may be only ±0.1°C. -

Page 8: Section 3 - Operation
Section 3 – Operation Circulator Location Locate the Circulator on a level surface, free from drafts and out of direct sunlight. Do not place it where there are corrosive fumes, excessive moisture, high room temperatures, or excessive dust is present. Refrigerating/Heating Circulators must be a minimum of four inches (102mm) away from walls or vertical surfaces so air flow around the unit is not restricted. -

Once the Safety Set temperature has been set, turn power to the Controller ON by pressing the Power Switch on the front of the Controller. The pump will begin operating, the display will flash the current temperature set point (tx.xx), the °C LED will light, and the current bath temperature will appear on this display. -

User-Defined Preset Temperatures With the unit on, press the desired Preset Button — P1, P2, or P3. The LED associated with the selected Preset Button will begin to flash. Rotate the Select/Set Knob to the desired temperature set point. Press the selected Preset Button a second time to enter the new set point. -

Page 12: Pump Motor
Pump Motor The pump bearings are permanently lubricated with high-temperature silicone grease and do not require additional lubrication. Should the bearings become noisy, replacement of the entire pump motor is recommended. This will reduce repair labor costs and retain fluid pumping reliability. Cleaning Only mild detergents and water or an approved cleaner should be used on the painted and stainless steel surfaces of the Circulator. -

No Heating • Verify that the unit is pumping properly. • If the heat light is not lit, check the control temperature set point and bath temperature to verify that heating is required. • Verify that the liquid in the bath covers the heater coils. •... -
Page 14: Section 6 - Reservoir Fluids
Section 6 - Reservoir Fluids Depending on your needs, a variety of fluids can be used with your Circulator. No matter what bath medium is selected, it must be chemically compatible with the reservoir and with the 300 series stainless steel in the pump and heater. It must also be suitable for the desired temperature range. Always use fluids that satisfy safety, health, and equipment compatibility requirements For optimum temperature stability, the fluid’s viscosity should be 50 centistokes or less at its lowest operating temperature. -
Page 15: Section 7 - Service And Technical Support
Application Notes At a fluid's low temperature extreme: 1. The presence of ice or slush adversely affects temperature stability. 2. A viscosity above 10 centistokes adversely affects temperature uniformity. 3. A high fluid viscosity and high pump speed adds heat to the fluid being pumped. At a fluid's temperature above ambient without refrigeration: 1. -
