Oct 16 (Reuters) - Private equity firm Sentinel Capital

Partners said on Thursday it sold the HVAC division of NSI

Industries to Lennox International ( LII ) for about $550

million in cash.

NSI Industries, a supplier of branded electrical components

across the U.S. and Canada, will streamline operations to focus

on its core electrical business, Sentinel said.

The HVAC sector has seen a wave of strategic deals,

including Bosch's $8 billion acquisition of Johnson Controls ( JCI )

residential and light commercial HVAC business in 2024,

as firms refocus on energy-efficient technologies and core

operations.

NSI will continue making components such as insulated

connectors and fittings under brands including Bridgeport,

Polaris and Tork.

Sentinel Capital acquired NSI in November 2024 at an

undisclosed sum.
