A2L-Compatible HVAC/R Tools From NAVAC

NAVAC has expanded its line of tools compatible with A2L refrigerants. The series extension comes amid news that the EPA will require technology transitions to equipment utilizing greener refrigerants beginning January 1, 2025.

Since legacy HFC refrigerants such as R-410A will still be used on a scaled-down basis, NAVAC’s portfolio of HVAC/R tools are designed to handle both newer and older refrigerants.

A2L refrigerants have higher flammability than their predecessors. Refrigerants in this class include R-32 and R-454B, which offer a lower global warming potential (GWP) than legacy products like R-410A. NAVAC is among the first HVAC/R manufacturers to offer a comprehensive line of A2L-compatible solutions, whose features include sparkless design, DC brushless motors, soft contact power switches, fans, and covered connections for all electrical terminations.

Highlighted solutions include:

Pro Series NP7DP2 Vacuum Pump features a dual-stage pump and a 0.75 hp motor, and delivers a 7 cfm flowrate and an ultimate vacuum down to 15 µm. The unit’s integrated cylinder structure, coupled with forced oil circulation, assures high performance and reliability.

NH5L Left-Handed Thread Hose helps ensure tight, leak-free connections to A2L refrigerant tanks. The thread hose is easily discerned from traditional thread hoses by its orange color and two rings on the reverse threaded side (versus one ring on a conventional thread).

N2A4B Manifold Gauge measures the pressure of various gases and liquids, helping technicians reduce leaks and system failures. Featuring a durable aluminum body and ball valves, the gauge can diagnose and determine the status of four refrigerants in total. The impact-resistant design includes a molded protective shell and rubber covering for shock absorption, and an integrated folding hook design offers ease of transport.

NP4DLM Cordless Vacuum Pump features a high-performance lithium battery capable of up to 1 hour of continuous running time.

NP2DLM Cordless Vacuum Pump is a compact, lightweight unit suitable for residential HVAC systems up to 5 tons with high-speed evacuation hoses.

NRP8Di and NRP6Di units are DC-driven vacuum pumps that feature digital control interfaces. The units offer unsurpassed intuitiveness with features such as task reminder, extended evacuation for improved vacuum, and precision vacuum measurement technology with a digital display.

NRDD Recovery Unit features a brushless DC motor that allows it to provide substantial power in a compact size and weight of just 25 lb. This DC technology also provides better starting performance under low voltage conditions.

The NRDC4M Recovery Unit operates up to 40% faster than 2-cylinder units and uses an efficient brushless DC motor and ultra-effective condenser with an oversized microchannel coil and 3 cooling fans.
