Shares in GEA Group AG jumped Wednesday after the mechanical engineering company said it would sell its heat exchangers unit to Triton Advisers Ltd., exiting the business to increase focus on food processing equipment.

The divestment, valued at EUR1.3 billion ($1.8 billion), gives GEA the financial headroom to pursue acquisitions in its core business of food and processing industry technologies, it said.

As part of its midterm strategy, GEA said last June it would shed the heat exchanger business, called HX, due to a lack of synergies with its core operations. Heat exchangers are used in air conditioning systems and cooling towers.

Shares rose as much as 6.8% in early trading, after the price surprised on the upside, analysts at DZ Bank and Baader Bank said. The transaction still requires antitrust approval but is expected to close by year-end.

Triton invests in medium-size businesses in the industrial, business services and consumer/health sectors. Regionally, it focuses on Germany, Switzerland, Austria and the Nordic countries.

Earlier this month, Triton agreed to buy Alstom SA's steam auxiliary components business for EUR730 million, part of Alstom's noncore disposal program. Since the beginning of the year, it has also made other investments in Germany and Norway.

"As an investor, Triton can offer a new perspective, enable us to leverage our growth potential and develop the company into an internationally important provider of heat exchange solutions," said Christoph Michel, the head of GEA's HX business.

Separately, GEA reported its first-quarter sales rose 2.9% rise to EUR951 million. With the divestment of HX, GEA will increase its food processing technology share to over 70% of group revenue, it said.

Full results for the quarter are due May 6.
