From a project delivered earlier this year including the design and production of a low pressure steam skid compliant with Class requirements, to be installed onboard a series of gas tankers as part of a ballast water management system. The skid uses low pressure steam on the hot side of the heat exchanger to increase temperature of fluid on the cold side. Steam pressure and flow can be adjusted by the flow control valve, through the combined action of cascaded controllers based upon the readings of transmitters located on both circuits.
