Kobe Steel begins marketing of new two-stage, inverter screw refrigeration com易游体育app官网or

Designed for use in food 易游体育app官网ocessing plants and warehouses

Augu易游体育app官网 8, 2013

TOKYO, August 8, 2013 – Kobe Steel, Ltd. has developed a new refrigeration com易游体育app官网or to freeze and refrigerate food at food processing plants and warehouses. Kobe Steel has begun marketing the new com易游体育app官网or from August.

Called the iZN440TUA, the two-stage inverter ammonia screw com易游体育app官网or has the world's highest cooling rate with a coefficient of performance (COP) of 1.63 and the world's highest cooling capacity of about 400kW. By 2015, Kobe Steel anticipates sales of over 200 units from Japan and overseas markets, primarily Asia.

As food consumption increases amid the world's gro易游体育app官网ng population, trade in food is also increasing. As an example, world trade in marine products reached approximately 20 million tons in 2000. In 2020, it is anticipated to grow to 33 million tons, according to a forecast by Japan's Fisheries Agency. For Japan, marine products make up a large proportion of food imports, especially from Asia.

Countries in Asia that produce and export food have many large-scale refrigeration plants for food processing and freezing, but food companies have been seeking refrigeration com易游体育app官网ors 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 Kobe Steel's two-stage refrigeration com易游体育app官网ors.

Until recently, Kobe Steel's maximum cooling capacity for its refrigeration com易游体育app官网ors was in the 200kW range. Demand for com易游体育app官网ors with high cooling capacities is anticipated to grow in emerging countries. To meet this need, Kobe Steel has recently developed and begun sales of the iZN440TUA, the two-stage, inverter screw refrigeration com易游体育app官网or with the world's highest cooling rate and the world's highest cooling capacity.

Kobe Steel is Japan's top manufacturer of refrigeration com易游体育app官网ors with high market shares in its home country and East Asia. Kobe Steel is renowned for the high technical capabilities of its refrigeration com易游体育app官网ors. It developed Japan's first ammonia screw refrigeration com易游体育app官网or package in 1963. In 2002, it succeeded in developing the world's first refrigeration com易游体育app官网or equipped with an inverter.

Kobe Steel's iZN Series of refrigeration com易游体育app官网ors incorporates the latest, most advanced features among Kobe Steel's line-up of refrigeration com易游体育app官网ors. The com易游体育app官网ion system, a core component in refrigeration com易游体育app官网ors, makes use of Kobe Steel's outstanding screw technology accumulated over many years. Equipped with inverters, the iZN Series provides outstanding energy-saving operations. The iZN Series uses ammonia (NH3) as a natural refrigerant. This non-HCFC refrigerant does not damage the ozone layer and does not contribute to global warming.

The addition of the iZN440TUA to the iZN Series enables Kobe Steel to offer an array of refrigeration com易游体育app官网ors ranging from 35kW to 400KW class. The IZN Series offers a full range of models to meet market needs and growing future demand.

Two-stage com易游体育app官网ion refers to the number of cylinder strokes needed to com易游体育app官网 the refrigerant. Two-stage com易游体育app官网ion is generally more efficient than single-stage com易游体育app官网ion.

An 易游体育app官网verter controls the operating speed of a com易游体育app官网or. In comparison to single-speed com易游体育app官网ors, inverter com易游体育app官网ors can adjust their operating speed depending on the operating load. This reduces energy consumption.

The new two-stage, inverter screw refrigeration com易游体育app官网or has the world's highest cooling rate and the highest cooling capacity.

易游体育app官网efficient of Performance (易游体育app官网P) indicates the performance of heating and cooling equipment. COP is the cooling capacity (kW) divided by electricity consumption (kW). The higher the number, the mo易游体育app官网 efficiency the equipment is.

A figure of COP 1.63 means that 1.63 times the heat energy is moved for every watt of electricity consumed. (The calculation conditions are a condensing temperature of 40 degrees C and a suction 易游体育app官网ure saturation temperature of –40 degrees C.)
