PureFlex is breathing new life into a vacant building on 44th Street.

PureFlex, an Andronaco Industries company founded in 1994, will expand a new line of production into the former MacDonald's Industrial Products site at 4242 44th St. Nil-Cor, another Andronaco Industry company, also will occupy part of the building.

Renovations have started and should be completed in the first quarter of 2012, according to Ron Andronaco, founder of PureFlex and Andronaco Industries.

He expects to hire an additional 12 to 20 employees.

PureFlex specializes in the manufacturing of fluid handling and sealing products.

"The building has good bones. The structure itself is sound," said Andronaco.

But the interior is in poor shape, and Andronaco estimates it will be a nearly $1.9 million investment to rehabilitate the facility and site.

"There is a tremendous amount of work that has to go into this facility. The pits are filled with water, all the plumbing has been smashed and destroyed. Wires have been stripped. It's a disaster inside," said Andronaco.

The nearly 100,000-square-foot facility has been vacant since 2006. It was built in many phases, starting in 1967 with the last addition in 1997, according to Deborah Ring, city assessor.

In late 2007, the property was listed for sale at $2.5 million. Since then, Ring reported the value of the property has dropped nearly 73 percent because of its obsolescence and physical deterioration from vandalism. The property’s true cash value, Ring said, is $629,400.

There also is environmental contamination caused by the former metal plating use on the site.

Andronaco requested a 12-year rehabilitation certificate to help bring the building back to usable condition.

City commissioners granted eight years.

That means the assessed value of the building will be frozen at the current level of $629,400 for eight years, even though at least $1.9 million in improvements will be made.

"I'm a huge believer in renovating instead of building new. My company is 17 years old. We started with three people and 1,200 square feet. Today we have 150 people and more than 400,000 square feet of manufacturing space," said Andronaco.

PureFlex has facilities at 4617 East Paris Ave., and Andronaco Industry headquarters are at 4855 Broadmoor Ave.

Andronaco Industries is the parent company for seven manufacturing companies including PureFlex, Nil-Cor, Ethylene, Hills-McCanna, Ram Parts Pumps, Poly Valve USA and Andronaco SAS in France. Combined, Andronaco Industries employs about 150 people.
