Eastern Technologies (ETI) has launched the COOLGARD Non-Phosphorus product line providing a phosphorus-free option for controlling scale and corrosion in industrial cooling and process water systems.
The company’s senior product line manager, Jim Sanford, said taking the phosphorus out was never the hard part.
“It was holding scale and corrosion control once it was gone,” he said.
“We tested the 14500 series against the phosphorus programs our partners were already running and kept at it until the numbers held.
“Now, we have a series of products that provide an environmental benefit without sacrificing performance.”
Phosphorus has been a workhorse of industrial water treatment for decades. Tightening discharge limits, disrupted supply chains, and customer sustainability commitments are pushing facilities to reduce or eliminate it.
Discharge permits are written on total phosphorus, and phosphonates count toward that number, so a program built on phosphonate chemistry can put a site over its limit even where no orthophosphate is being fed.
Water treatment professionals are increasingly being asked to move away from the P-based chemistries the industry has long relied on, without giving up the equipment protection or operational performance those programs provide.
COOLGARD has launched four formulations built on proven polymer chemistry.
COOLGARD 14505 and 14510 balance performance and cost efficiency, an entry point for programs transitioning away from phosphorus under standard operating conditions.
COOLGARD 14515 and 14520 add performance margin through zinc for more demanding systems, where corrosion inhibition needs are higher or water quality is more challenging. COOLGARD 14510 and 14520 incorporate a tagged polymer for enhanced monitoring on critical systems.
ETI developed all four formulations through disciplined performance evaluation and cost-in-use analysis, so a water treater can recommend the line on validated results rather than positioning or relationship alone.
The COOLGARD line complements ETI's existing phosphorus-based cooling water programs, giving partners the flexibility to match chemistry to each customer's regulatory, sustainability, and performance requirements.
