Does the process require any control interface with the fluid-heating system for monitoring or control purposes?
If the fluid control system is acting independently of the process control system, there must be adequate process monitoring and safety devices to determine if the fluid system is performing properly. What services are available for operating the system? The processor needs to evaluate all available utilities, including electrical, gas, steam and water. What temperature accuracy is required by the process? The process equipment and fluid-heating system must be capable of attaining this requirement. Could the process or fluid system be affected by seasonal temperature changes? These seasonal changes result not only in variances in ambient air temperature, but more importantly, in fluctuating supply water temperatures where cooling water is used to cool the fluid-circulating system. If seasonal weather changes significantly affect process efficiency, the fluid system should be designed to limit this effect accordingly (for example, an additional chiller system may be required).
