Horizontal inner Tube Evaporator (HiTE) - Marine Freshwater Generator

The Wärtsilä Horizontal inner Tube Evaporator (HiTE) is a multi-effect evaporator specifically designed for producing small to medium capacities of 30 to 175 tons of distillate per day. This marine freshwater generator guarantees potable water for human consumption and clean process water for technical applications. It serves in a wide range of operational areas where alternative technologies like reverse osmosis or plate technology reach their limits. Shallow waters with poor seawater quality is an example of this. The HiTE operates smoothly even at partial load. For example during dynamic positioning (DP) operations. The unit’s control system can be fully or semi-automated. Its smart processes adapt automatically to the amount of energy available. The HiTE is able to use waste heat. This is very convenient for vessels with varying engine profiles. The 4-stage HiTE offers up to 75% energy savings with a specific heat consumption of 180 kWh/t compared to single stage designs (700 kWh/t). For a 3-stage HiTE this is 240 kWh/t. Low operational cost | High reliability | 30 - 175 tons distillate per day | Uses waste heat from ships with varying engine profiles
