  In the world of industrial cooling, scroll air-cooled chillers are spearheading an energy-efficiency revolution. Among them, the newly launched 800kW chiller by   H.Stars Group   has quickly become a topic of industry discussion. But what qualifies as a “large-scale” unit in this field? Let’s decode the standards of industrial chiller classification from a technical perspective. 1. Understanding Chiller Size Classifications In the HVAC industry, the size of a chiller is defined by more than just its physical footprint. According to ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers),  scroll air-cooled chillers  can be categorized by cooling capacity as follows (for reference): • Small Units: <200kW • Medium Units: 200–500kW • Large Units: >500kW This classification considers system integration, efficiency curves, and actual application environments—not just output power. International giants like Trane and Carrier follow s...

  In the maritime industry,   heat exchangers   play a vital role in ensuring the efficiency and safety of ship operations. Marine heat exchangers made with stainless steel tubes and nickel-copper tube sheets have emerged as the preferred solution due to their exceptional performance and durability. Advantages of Stainless Steel Tubes in Marine Heat Exchangers Stainless steel is renowned for its outstanding corrosion resistance and high-temperature tolerance. In the harsh marine environment, where seawater and various working media pose significant corrosion risks,  stainless steel tubes  offer long-lasting protection and efficiency. Their high strength and excellent processability enable them to withstand high pressure, making them well-suited for the complex and variable conditions ships often encounter. Benefits of Nickel-Copper Alloy Tube Sheets The use of nickel-copper alloy combined with carbon steel for tube sheets provides superior corrosion resistance, ...
