ECD unveils new panel-mounted peracetic analyser

CALIFORNIA, February 18, 2016

Electro-Chemical Devices (ECD), a manufacturer of liquid analytical process instrumentation, has unveiled its new panel-mounted PA80 Peracetic Analyzer, which will simplify the process monitoring to ensure disinfection without the need for potentially harmful disinfection byproducts (DPBs).
 
The plumb-and-play design of ECD’s economical product will allow a single technician to install the unit right out of the box with no special tools or complex calibration routines, said a statement.
 
Ready to go from the factory, the PA80’s cost-effective design includes built-in flow control, and so there is no need to purchase or install pressure regulators and rotameters, which are typically an extra cost with many other types of liquid analysers.
 
​Peracetic acid is a colourless liquid with a characteristic pungent odour similar to vinegar, it said.
 
It is produced by a reaction between hydrogen peroxide and acetic acid.  Produced typically as an equilibrium solution combining these agents, PAA is supplied in concentrations of five to 15 per cent and is a powerful oxidiser, stronger than either chlorine or chlorine dioxide.
 
​The rugged and reliable PA80 features multiple PAA measurement ranges:  0-20, 0-200 and 0-2000 ppm.  Providing multiple measurement ranges will allow plant engineers to select the monitoring range that best fits the requirements of their product batch recipes, their processes and equipment cleaning requirements.
The food and beverage, medical and pharmaceutical industries all rely on PAA as a cleaner and sanitizer of process equipment, medical instruments and for bottle washing. It is also used as a disinfectant in municipal wastewater treatment and industrial cooling towers.
PAA is a highly effective bactericide that does not form any harmful disinfection by products (DBP) like many chlorine products do. It decomposes naturally into acetic acid and water and does not form a residual that has to be removed from the treated water.
 
The PA80 Analyzer’s transmitter is 110-240 VAC or 24 VDC powered and will allow either parameter to be graphically displayed with user defined line, bar or gauge style graphs. The standard configuration has two four-20 mA outputs, three alarm relays and an industry standard MODBUS RTU (remote terminal unit).
 
​Relying on precision amperometric PAA sensors that are flow sensitive, the PA80 will provide accurate measurement with a minimum flow rate past the sensor of 0.5 ft per sec; above this flow rate the output is virtually flow independent. 
 
To reduce maintenance technician time and costs, the PA80 will feature an optional auto clean configuration, which includes a solenoid actuated spray cleaner that uses either 30 psi process water or air. 
 
An easily adjusted timer will control the period and duration of the cleaning cycle. The optional spray cleaner will also eliminate fouling to protect batch sensitive products and prevent process line downtime. - TradeArabia News Service
