HVAC/R Leader NAVAC Introduces Vacuum Pump for Ammonia-based Refrigerant Applications

Model NP12DA1 Ammonia Vacuum Pump protects against ammonia-related corrosion while offering flow rate of 12cfm with fast, powerful and robust performance.

Lyndhurst, NJ – NAVAC, the world’s largest supplier of HVAC vacuum pumps in addition to a wide array of tools, gauges, charging machines, recovery units and other industry-specific items, has introduced a robust, corrosion-resistant vacuum pump designed to guard against the damaging effects of ammonia-based refrigerants. Part of the company’s Master Series of HVAC/R solutions, the NP12DA1 Ammonia Vacuum Pump combines protection with power via an impressive flow rate of 12cfm for fast, heavy duty performance.

Anhydrous (dehydrated) ammonia, which is commonly used in industrial facilities as a refrigerant for cooling and freezing, is a highly corrosive substance. In fact, its widespread use as a refrigerant is one reason why vacuum pumps have, historically, been considered disposable HVAC tools. The new NAVAC Ammonia Vacuum Pump pushes back against this wasteful trend with a stainless-steel inlet port and corrosion-resistant pump, protecting against ammonia’s adverse effects for a significantly lengthened product lifespan.

Sectors in which ammonia-based refrigerants are prevalent include meat, poultry, and fish processing facilities; dairy and ice cream plants; fruit juice, vegetable juice, and soft drink processing facilities; cold storage warehouses; and petrochemical facilities. Ice rinks also frequently utilize anhydrous ammonia.

NAVAC’s NP12DA1 Ammonia Vacuum Pump features an industrial-grade design for a rare blend of robustness, speed and power. Its brushless DC-motor technology maintains peak efficiency while yielding a superior starting performance under low starting amperage and soft-starting down to 30°F, and its twin-cylinder functionality and precision manufacturing provide an industry-leading ultimate vacuum down to 5 microns.

Other features and benefits of the NP12DA1 include adjustable gas ballast for superior moisture handling capability, high-performance oil mist filter for a clean environment while saving pump oil, a recessed power switch safeguarding against tripping and rain, ball-valve oil drainage design, and a low operating sound level.

“By insulating critical components from the harmful effects of ammonia-based refrigerant, our new Ammonia Vacuum Pump aligns with NAVAC’s larger goal of making technicians’ jobs easier and more efficient, in this case through enhanced equipment lifespan and reliability,” said Stephen Rutherford, VP of HVAC Tools Business for NAVAC. “The Ammonia Vacuum Pump also has a sustainability element to it, since tools that must be replaced frequently are inherently less eco-friendly than those, like the new pump, that can be used for extended time periods.”

NAVAC is a global manufacturer that has dedicated over 20 years to the R&D and manufacturing of industrial vacuum solutions and HVAC/R tools. NAVAC draws upon its commitment to technical innovation, strong customer service and robust R&D allocation to deliver solutions offering unsurpassed efficiency, accuracy and ease of use.

Comprising a full lineup of tools, gauges, detectors, charger and vacuum pumps, among other solutions, NAVAC’s product portfolio is designed with one overarching concept in mind: user-friendliness. The company seeks to meet a need for simpler, lighter, faster solutions that expedite service without sacrificing accuracy. For more information, www.navacglobal.com.
