The City of Tempe, Arizona recently completed a water quality upgrade to their 50 million gallon/day water treatment facility. This project included an upgrade to their dosing systems for Sodium Hypochlorite (NaOCl), which is used to disinfect the water. Special materials (CPVC, PTFE, and hastelloy) were required as Sodium Hypochlorite will corrode standard materials such as Read More

Ever wondered why your Equilibar Application Engineer recommended a Polyimide diaphragm instead of a stainless steel diaphragm? Because our back pressure regulator has only one moving part, the choice of diaphragm selection is complex by necessity. However, our new Diaphragm Selection page sheds a little more information on the diaphragm selection process. If you are Read More

Jeff demonstrates the amazing precision of the EB1HP1 back pressure regulator through a 40,000 to 1 flow rate ratio while maintaining stable inlet pressure.   The video demonstrates controlling Nitrogen gas at a pressure of approximately 1000 psig, and flowing from a range of 1 ml/minute up to 40 liters/minute (a wide flow rate range Read More

The Equilibar® back pressure regulator is being used by the Chemical Engineering Department at the University of Texas at Austin to study membrane fouling in applications such as industrial water purification. The stainless steel regulators are being used together with the Equilibar QPV electronic pilot regulator to create a high precision low pressure control for Read More

In early April, I spent a week visiting petroleum industry clients in the Houston and Austin areas. While I knew this sector was growing due to booms in oil and gas exploration, I was amazed to see the amount of growth first hand. One key growth area for Equilibar back pressure regulators is in petroleum Read More

Equilibar’s precision vacuum regulators are finding success in the control of Dental Suction Systetms.The typical dental facility has one vacuum pump being shared by a large number of operatories. The result is highly variable suction available to the suction tool. Our EVR Series vacuum regulating valves are able to provide stable vacuum levels despite widely Read More
