ABSTRACT:
Temperature control apparatus for a system for testing drilling mud includes instrumentation for measuring the parameters of the drilling mud, and a pump for pumping the drilling mud in a recirculating path through the instrumentation. A mud heater in the recirculating path heats the mud and a heat exchanger connected in the front of the heater in the recirculating path cools the mud before it is heated. The heater and the heat exchanger are controlled to maintain a constant differential across the heater. The heater is constructed in a manner which provides low thermal mass, thereby providing a fast response time for changes in temperature.
