Due to its superior thermophysical properties, water is an ideal heat transfer medium. Closed loop liquid phase hot water or glycol solution systems are an excellent choice for indirect process heating up to approximately 300F. Because the water is used in a closed loop with no direct feedwater source, heaters are typically built to ASME Section VIII and do not require a licensed boiler operator. Heaters can be built to ASME Section I when required.
