The SONDEX Marine Plate Range.

By means of technological innovation SONDEX has developed and designed a new generation of plate heat exchangers specially for the marine sector. With these specially designed plate heat exchangers it has appeared that the SONDEX plate heat exchangers can be major player on the marine world market. With technical innovation and a world-wide service net it is our aim to keep and extend our previous market position.

The SONDEX Plate Heat Exchanger The SONDEX plate heat exchanger has today become a standard component in the cooling system of many marine application designs. Our heat exchanger is designed according to the ship classifications bureaus specifications and rules securing the shipowner that his SONDEX plate heat exchanger is designed to meet the high demand for quality which is necessary in order to give a long lifetime and a trouble free use of the plate heat exchanger.   The SONDEX Marine Plate Range The range of SONDEX Marine plate heat exchangers consists of 30 plate types each with 2 different corrugations (thermal hard and thermal soft). The range consists of plates with areas from 0.04 m²/plates to 2.00 m²/plates and from 1" to 14" connections enabling us to handle flow rates up to 2000 m³/hr. The frame edge clamped with normal industrial painted frame or in coated frame.

Space and weight requirement The space requirement and weight of the equipment onboard a ship today is more important than ever. Therefore it is very important to choose the right equipment. The difference between a traditional tubular heat exchanger and a SONDEX plate heat exchanger is major. In space- as well as in weight-requirements there is a lot to save with a SONDEX plate heat exchanger:   • The weight of the plate heat exchanger only amounts to 20%.   • The size is only 30%.   • The K-value is 4-6 times higher • Easier to service.   • Longer durability and less price raising costs.

Freshwater Pump.  Most cooling systems are made as central cooling systems, meaning that only one or two bigger plate heat exchangers are equipped with titanium plates. Titanium is the only material that can withstand the aggressive seawater without corrosion damages on the plates in the heat exchanger. This means that the central cooler can operate without problems using seawater as the cooling media for the internal freshwater cooling system. The advantage of a central cooler is that the use of the corrosive seawater is limited to one or two plate heat exchangers, and thereby the use of exotic material for the plate heat exchanger and the seawater pipeline is limited to a minimum, which will reduce the corrosion damage in the cooling system. The rest of the plate heat exchangers are normally equipped with stainless steel plates. There is no corrosion risk as the heat exchangers work with freshwater.
