Engine Coolant, Oil and Turbo/Intercooler
Engine Fluid Temperature Control
- Cooling of up to four control circuits
- Only two connections required for feed and return water
- Compact unit reduces clutter in the cell
- Proportioning valves aid accurate flow control
Overview
The Sierra temperature control assembly is designed to provide temperature control of engine coolant, engine oil and turbo/intercooler (or other cooling circuits) in engine test applications, from a single bed water feed and return. The compact module supports the rapid control of coolant flow through the three independent bed water circuits. These circuits are usually connected to suitably sized heat exchangers, which in turn are connected to the engine circuits. Sierra can offer a cooling post which is a single unit that integrates the valve manifold and appropriately sized heat exchangers.

Applications
- Engine test work where air cooling of radiator is not appropriate
- Emissions work to control engine fluids to within allowable limits
- Connect to existing Heat Exchangers for automated PID control
The flow rate to the heat exchanger for each valve manifold circuit is controlled by adjusting a 3-way electro-pneumatically actuated ball valve. The flow range/back pressure of each circuit is manually pre-set by adjusting integral ball valves within the valve manifold, which allows the manifold to be used with a wide range of engine sizes.
Closed loop temperature control is achieved by integrating PRT sensors into the engine circuit supply pipework. The 3-way valves are then actuated such that the bed water flow through the heat exchangers is sufficient to remove the required amount of heat and thus provide the necessary engine circuit supply temperatures. The valve manifold can be controlled by a CADET V14 host, or the CADET V14 Indepentant AK Fuel Controller.
