Cooling, Heating & Energy transition

Surface water heat exchangers

Water from canals, rivers, lakes and the sea is an extremely suitable source of energy. With a heat exchanger, this water can be used as a source of heating or cooling. In cooperation with partners, Mosman has developed specific heat exchangers for surface water.

Heat exchangers for energy transition

The smart use of natural resources plays an important role in the energy transition. Surface water, for example, is ideal for cooling buildings or homes in summer and heating them in winter. The heat from effluent water, purified waste (water from sewage treatment plants), can also be used as a source of energy, which can be done with the aid of heat exchangers. The disadvantage of surface water is that it contains residues, bacteria and other (shell) animals. This causes the growth of algae and mussels, causing heat exchangers to clog up. Mosman produces heat exchangers for effluent and surface water. The relatively large plate spacing of Mosman's pillow plates, in combination with UV-C light to stop organisms from growing, prevents the heat exchanger from clogging up. This guarantees an optimal operation of the heat exchangers and minimizes maintenance.

Heat exchangers for cooling industrial processes

Many industrial processes require constant cooling. Millions of cubic litres of cooling water are used to cool processes every year. Surface water is an excellent source for this. A Mosman heat exchanger is used to make surface water suitable for process cooling.

UV-C marine coolers

Ship cooling is an essential part of a ship and (sea) water is a suitable source for this. Together with its development partners Mosman and Philips, Corrosion has developed ship coolers that combine efficiency with a low maintenance interval. Pillow plates from Mosman are used in these ship coolers. For this application Mosman has developed heat exchangers with the pillow plates that are far enough apart from each other to realize a large radiation range for UV-C light. The Slot Manifold technology enables us to realize a compact solution. This creates a heat exchanger with compact dimensions and a large plate surface area. The advantage of using heat exchangers with UV-C lamps, is preventing algae, mussels and other organisms to grow. In this way, the ship's cooler will function optimally under all conditions and the required maintenance is kept to a minimum. This prevents expensive and time-consuming downtime and contributes to a high uptime of a ship.

The advantages of the mosman heat exchanger

  • No risk of caking
  • Up to 90% more energy-efficient than direct heating or cooling
  • Unlike fluid-bed air dryers, coolers and heaters, no air filters are necessary
  • Easy access via wide-access doors and hatches
  • High-quality cooling and heating: homogeneous heating and cooling by creating mass flow
  • Modular structure, so easy to install, mount, commission and maintain

How does a bulk solids
heat exchanger work?

Bulk solids are distributed over the pillow plates in a hopper, in which a level indicator is used to measure the fill level and flow rate too. To ensure that the bulk solids are heated to a uniform temperature, an even flow must be achieved across the entire surface of the heat exchanger. This so-called mass flow is created by means of an outlet designed especially for this purpose. As a result, every particle of the bulk solids flows through the heat exchanger at the same rate and are consequently in contact with the pillow plates for the same length of time. A temperature sensor in the product outlet ensures that the bulk solids are at the temperature required as they leave the heat exchanger.

Given the above, the Mosman heat exchanger consists of just two independent control loops: one for the bulk solids and one for the temperature of the bulk solids. This results in a system that is easy to operate and control.
