Air compressors, often known as the fourth utility, are a key driver of business success. As such, companies cannot risk air compressor failure during operation. Operators need a product that delivers reliable, innovative, efficient, and cost-effective compressed air, which is why many companies turn to the experts at Kaishan USA.

Kaishan KRSD single-stage direct drive compressor line is one of our most popular lines of compressors. These KRSD compressors utilize rotary air compressor technology to deliver a constant stream of compressed air where and when you need it most. This air compressor type uses helical screws in a continuous motion to reduce the volume and maximize the pressure of incoming air. Precision machining and proprietary bearing design within the industrial rotary screw air compressor airend hold the male and female screws, or rotors, in precise alignment.

ORC POWER GENERATORS

ORC Power Expander

Kaishan is a leading manufacturer of organic Rankine cycle (ORC) power generation systems. Our products currently generate nearly 100 MW of power in facilities around the world, where they play a key role in curbing CO2 emissions and reducing overall environmental impact.

The Rankine cycle is the scientific name for the idealized thermodynamic cycle of a heat engine. In these products, heated fluid from a customer process is exchanged with a refrigerant, then expanded back into a cold liquid through a rotary screw airend, similar to those used in our rotary screw air compressors. This refrigerant expansion to liquid creates rotational energy through the screws, turning an electrical generator, thus converting heat energy to electrical energy. In these generators, energy is produced from lower temperature sources to reduce greenhouse gas emissions.

Kaishan’s ORC power plants feature a patented screw expander system capable of improving isentropic efficiency by as much as 90% compared to conventional turbines. Our ORC expanders are versatile and easy to fit into your existing workflow, with multiple condenser options and power generation capabilities ranging from 50kW to multi-megawatts.

ORC Power Generator BenefitsLower Cost: ORC generators provide the opportunity to recover heat from lower temperature sources compared to traditional steam turbines. This opportunity can provide significant cost savings for your organization. Compared to other renewable power solutions, the combined cost of purchasing and running an ORC system is relatively low, making it one of the best values for organizations looking to improve their environmental credentials.Higher Reliability: The simplified system and lower operating speeds of a rotary screw ORC expander offers high reliability in smaller waste heat recovery applications. Maintenance is typically limited to servicing valves and maintaining the lubrication system.Eco-Friendly: ORC power generation is a 100% clean solution with no emissions or byproducts. Depending on where they are used, these systems may help companies qualify for carbon or renewable energy credits. These credits can further help reduce operational costs.Safer Operation: The rotary screw ORC runs under less pressure and rotates more slowly for improved worker safety. Pump components do not experience continual exposure to water, so they are less likely to rust or erode—which increases their operational life.
