"World's coolest chiller" is launched, promising 400 kW cooling capacity

Kobe Steel unveils two-stage ammonia screw compressor promising to deliver a world leading cooling capacity for industrial applications.

Kobe Steel has developed a new ammonia screw compressor to freeze and refrigerate food at food processing plants and warehouses claiming a cooling capacity of 400 kW and a COP of 1.63.

The iZN440TUA is aimed particularly at the food processing plants of Japan and Asia, where imports and exports of food is increasing rapidly. For example, Japan’s Fisheries Agency forecasts world trade in marine products will soar from 20 million tonnes in 2000, to 33 million tonnes by 2020. For Japan, marine products make up a large proportion of food imports, especially from Asia.

Kobe Steel notes that countries in Asia that produce and export food have many large-scale refrigeration plants for food processing and freezing, but the food producers have been seeking refrigeration compressors with larger capacities and higher energy savings. To maintain quality during freezing, the refrigeration industry has also been cooling at lower temperatures, which is a specific feature of the company’s two-stage refrigeration compressors.

The manufacturer said that until recently, the maximum cooling capacity for its refrigeration compressors was in the 200kW range, but to meet demand for compressors with high cooling capacities from emerging countries, it had doubled capacity.

The company claims to be Japan’s top manufacturer of refrigeration compressors, developing the country’s first ammonia screw refrigeration compressor package in 1963 and the world’s first refrigeration compressor equipped with an inverter in 2002. Equipped with inverters, the iZN Series provides outstanding energy-saving operations, the manufacturer says.
