Honeywell International, the listed, New Jersey-based diversified technology and manufacturing company, continued its acquisitive streak with a deal to buy E-Mon LLC from Branford Castle. Terms of the deal were undisclosed.

E-Mon is a Pennsylvania-based maker of smart energy meters. Calls seeking comment were not acknowledged by press time.

Honeywell shares traded up about three percent as of mid-afternoon Thursday.

Acquired by Branford Castle in 2007, E-MON manufactures submeters and interval data recorders and also provides automated meter-reading and analysis software.

While a sale price was not publicized, the short holding period would seem to suggest a profitable exit for Branford Castle, which bills itself as "a long-term investor" in the small to medium-sized deal space. Founded by Castle Harlan's John Castle, Branford targets companies with enterprise values below $75 million and will make both control and non-control investments. The firm, according to its website, has roughly $200 million of equity at its disposal.

The firm also owns American Condenser & American Coil, an air conditioning parts maker; Washington Chain & Supply Co., a marine supply business; Lister Chain & Forge, another naval supply company, and Canada Metal Ltd.

Honeywell, meanwhile, has been actively targeting this space. It acquired natural gas measuring products maker RMG Group last year and bought smart grid company Akuacom earlier this year.

Harris Williams' Cobblestone affiliate served as advisor on the deal, with Drew Spitzer, Tiff Armstrong, Harold Williams and Karl Kirkeby all assisting on the transaction.

The energy sector has drawn a significant amount of activity in the first half of 2010. Just this week, Navigation Capital Partners agreed to acquire LEPService, a smart grid supporting infrastructure development.
