Nearly all steam-driven plants, whether it be nuclear, coal, natural-gas, solar thermal, has a condenser sitting behind the steam turbine. Its job is to cool the steam back down into liquid water, pulling more steam through the turbine in the process. The better the heat transfer between the steam and the coolant flowing in the condenser, the more efficient the plant runs. 

DropWise coatings boost the thermal performance of steam surface condensers significantly, resulting in an improvement in the plant "heat rate" (a measure of efficiency). This saves the plant not only on fuel and emissions, but also helps reduce coolant water usage to aid in 316b compliance. 

Nearly half of the world's saltwater desalination capacity comes from thermal distillation plants, whether by a Multi-Effect Distillation (MED), Multi-Stage Flash (MSF), or Thermal Vapor Compression (TVC). A desalination plant is essentially a massive train of condensers, where the  cost of the heat exchangers exceeds 1/3 of the total capital cost. DropWise coatings provide an opportunity to shrink the size of the condensing surfaces by more than 30%, delivering substantial savings in the cost of fresh water. 

DropWise coatings work to enhance condensation of more than just steam...

Our coatings have been demonstrated with natural refrigerants including ammonia and pentane. These systems are extremely sensitive to condenser performance: for every 1°F decrease in condenser temperature, chiller efficiency improves by ~2%. DropWise coatings enable energy savings, reduced coolant water usage, and prevent a facility from having to de-rate chiller capacity during hot ambient conditions. 

Chemical refineries of all types of products, from petroleum derivatives to polymers, rely on several different types of condensers to enable their processes: from steam reboilers to vapor-reclamation condensers, there are several opportunities for substantial process improvement by using DropWise-coated condensers. The enhanced condensation heat transfer enables higher throughput, reduced steam generation requirements, and process de-bottlenecking.
