Fieldpiece Instruments, the industry leader in tools and test instruments for HVACR professionals, announces two new SMAN Refrigerant Manifolds that have been refined to offer the ultimate in field performance. Years of feedback from A/C and refrigeration professionals is combined with Fieldpiece’s laser focus on continuous improvement to bring one of the toughest, most advanced digital manifolds to HVACR.
The extremely rugged case not only protects the manifold from field use, it also makes it water resistant with an IP rating of 54. Thermocouple ports have been moved to the rear for added protection and a streamlined setup. The manifolds are optimized for live readings and receive direct long-range (up to 350’) wireless measurements directly from the Fieldpiece Job Link Probes and SRS3 Wireless Scale with no transmitter required. Models SM380V (three-port manifold) and SM480V (four-port manifold) are both wireless and have built in micron gauges. They are targeted to be available at distributors spring 2019.
The new SMAN manifolds will easily help the HVACR professional check, evacuate, and charge systems faster. The pro can view the calculated target superheat while monitoring, in real-time, how their charge is affecting actual superheat and subcooling. All measurements and live calculations can be viewed on the extra large LCD or from a distance or on a mobile device with the Job Link® System App. Up to nine jobs can be saved to the internal flash drive.
The large vacuum port on the SM480V matches perfectly with Fieldpiece Vacuum Pump models VP55 and VP85. While the refrigerant port on both models can be used to connect to a refrigerant cylinder directly, or to a recovery machine like Fieldpiece model MR45.
More than 70 refrigerants are pre-programmed into the manifold and future refrigerants can be added by utilizing the micro USB port. A rolling list of the ten most recently used refrigerants is stored at the top of the main refrigerant list for quick selection. When the manifold powers off, the current refrigerant is added automatically to this dynamic list of ten.
The new manifolds are customizable with the ability to adjust auto power off duration, adjust backlight duration, set high and low vacuum alarms and select each unit of measurement individually. In addition, a Tightness Test function is available to check for leaks after repairs or installations and to allow the pro to view pressure differential over time. A timer tracks the duration of the test and temperature is compensated with SL temp to avoid false positives.
In addition to the included thermocouples, you can connect wirelessly to psychrometers, pipe clamps, and even a refrigerant scale. For example, assign one psychrometer (model JL3RH) to return air and another to supply air to view live temperature split across the evaporator directly.
“It’s our job to make HVACR pros’ jobs easier, faster, and better,” said Russ Harju, product manager at Fieldpiece. “These new wireless refrigerant manifolds do just that, especially with the large screen that’s so easy to read, and the new, more rugged, upgrades.”
