Telx, which provides interconnection data services, has bought the data center location it has been leasing at 100 Delawanna Ave. in Clifton, which is near its new $200 million, flagship facility that’s slated to open this spring at 2 Peekay Drive, the company said Wednesday.

Telx bought the Delawanna location, which has 80,000 gross square feet, from Mountain Development Corp. The terms of the purchase weren’t disclosed.

Along with the new facility under construction across the street, Telx will now have a fully owned Clifton site, where it said it plans to develop an advanced data-center campus and future technology center for the evaluation and development of data-center products and services for clients.

With full control of both facilities, Telx “has started investing in property upgrades that will allow these facilities to comply with the most stringent of security and operational requirements,” the company said in a statement.

“Security upgrades will include a perimeter fence with anti-climb and intrusion detection technology, guarded perimeter property gates, full campus surveillance using advanced imaging technologies and other undisclosed new security enhancements,” Telx said.

Telx’s Peekay Drive data center has 215,000 gross square feet of high-power density space and more than 100,000 square feet of customizable co-location space. The adjacent Delawanna facility has 60,000 square feet of “white space.”

“We intend to develop both assets into a world-class interconnected property with both buildings adhering to some of the most stringent compliance requirements,” Telx Chief Executive Officer Eric Shepcaro said in a statement. “We are also excited to be able to fully control this entire location with new operating procedures, a secure perimeter and the development of a new Telx technology center for future R&D and product development. In fact, we have already begun evaluating wireless and other technologies between this location and our Manhattan data centers.”
