Description

Aalborg EH-S (formerly VESTA™ EH-S) is a flow through electrical heat exchanger, ideal for steam production. The Aalborg EH-S is installed horizontally and comes as a complete unit with control cabinet and pre-mounted pump, safety valve and non-return valve, ready for installation. Connected to the auxiliary steam boiler, the Aalborg EH-S heater is for certain ship types replacing or acting as a Donkey boiler and an alternative to conversion of boilers for MGO operation. The Aalborg EH-S heater complies with European standards and is designed for easy approval by the classification socities. For certain ship types, the installation of the Aalborg EH-S electric flow through heater may be the ideal option for the socalled harbour / hotel mode. The return on investment is shown below based on the actual specifications and conditions of operation. The curves of the diagram represent the typical investments and running costs for a 47,000 DWT Product Carrier with a 20 t/h boiler plant and an economizer. The “EH-S” line indicates the gen-set operated electrical heater type Aalborg EH-S with a steam production of approx 300 kg/h usually considered sufficient for harbour / hotel mode. The “Aalborg OS” line indicates the investment and running costs for a 1.2 t/h boiler with a fuel oil consumption of 30 kg/h. The “Aalborg-OL” line indicates the running costs for an existing 20 t/h boiler with a fuel oil consumption of approx 80 kg/h. As this is an existing installation, the costs of investment are not considered.
