Japan’s Daikin Industries said on Monday it would buy Austria-based AHT Cooling Systems for 881 million euros ($1 billion) as it seeks global growth outside the maturing air-conditioning business in the developed world.

Daikin, the world’s largest maker of air-conditioning equipment, said it would buy all of unlisted AHT Cooling, a refrigerator maker for business use, from British investment firm Bridgepoint.

The purchase of AHT Cooling would solidify Daikin’s foothold in Europe, while helping to expand its refrigeration business in the United States and Asia, the Osaka-based company said in a statement.

AHT has production sites in Austria, the United States, China and Brazil.

Daikin has been setting its sights overseas and beyond its mainstay air-conditioning business, buying Italy’s Zanotti, a maker of industrial cooling and freezing equipment, for 98 million euros in 2016.

Having succeeded in grabbing a high share of Asia’s emerging air-conditioning market, particularly in India, Daikin is aiming to expand in Africa, where South Korea’s LG Electronics and China’s Haier are established giants.

Daikin’s shares closed up 3.2 per cent on Monday, outperforming the Nikkei 225 average which rose 0.76 per cent
