Fieldpiece Instruments’ (www.fieldpiece.com) SMAN4 is a four-port, wireless digital manifold that has a 3/8-inch port for evacuations and recovery. The four ports allow technicians to evacuate a system, pull a vacuum, add refrigerant, and dial in the charge at one time without having to hook or unhook any hoses.

Fluke Corp.’s (www.fluke.com) CNX Wire System wirelessly connects multiple measurement modules and sends simultaneous readings to a master device up to 20 meters away, allowing users to troubleshoot problems. The customizable tool set allows users to choose various measurement modules based on their specific troubleshooting scenario to read the measurements outside the arc flash zone.

General Tools & Instruments’ (www.generaltools.com) digital refrigerant leak detector (RLD400), which features a semiconductor sensor lifespan of more than 300 hours of operation or 10 years normal use. Three sensitivity levels let users choose the right level for specific environments.

Hilmor’s (www.hilmor.com) electronic gauge with vacuum sensor is a hybrid gauge with both analog and digital readouts with lights color coordinated to the selected refrigerant. It also features a micron gauge, self calibration, and is accurate to within 1 percent. The company also recently introduced a dual readout thermometer with thermocouple clamps that can be attached to any manifold using the hook provided. The tool features two digital temperature readouts so calculating superheat and subcool no longer requires multiple tools. An aluminum manifold has a forged aluminum body with rubberized handles, protective gauge boots, replaceable stainless steel valve stems, and a pressure indicator ring that allows users to mark a spot with a marker.

Polar Technology (www.refrigerantauthority.com) recently introduced TrakRef®, a proprietary and comprehensive refrigerant management program. As explained by the company, the product is designed to provide comprehensive and transparent tracking and management of refrigerants throughout their entire lifecycles. This includes from the time of purchase to deployment throughout maintenance cycles, through recovery and reclamation, to their final destruction at the end of the lifecycle. When the program is incorporated among the participating points in the supply chain, more of the original refrigerant is kept within the supply chain, ownership of the refrigerant can be accounted for, and regulatory compliance is inherently managed. It is available in three customized versions for contractors, distributors, and system owners.

Refco Mfg. Ltd.’s (www.refco.ch) Enviro is a one-knob operation refrigerant-recovery machine. It allows for recovery of all popular CFC, HCFC, and HFC refrigerants using an oil-less, air-cooled compressor. The Enviro is equipped with a self-purging mode as well as a built-in filter.

RefTec Intl. Systems LLC‘s (www.reftec.com) BullDog recovery/recycle/reclaim unit is available in three sizes, the unit processes R-22, R-134a, R-410A, R-11, R-123, and other common refrigerants with the same unit. It processes gas at speeds of 600 pounds per hour. Features include zero cross contamination of compressor oil to gas, portable design so it fits through standard 36-inch doorways, and single power source for unit and controls. The 80 percent tank-full float switch and 12-foot float cable ensure cylinders are not being overfilled.

Robinair (www.robinair.com) introduced the RG3000 Cube, a compact and lightweight refrigerant recovery machine from Promax. It is designed for liquid and vapor recovery of commonly used CFC, HFC, and HCFC refrigerants including R-410A. Equipped with a high-pressure shift-off switch, the machine automatically shuts off if pressure rises above 550 psi, helping to prevent pressure building in a tank or machine. The high-efficiency, cross-flow airflow design allows for more efficient refrigerant recovery leading to shorter cycle times, the company said. The company also displayed a refrigerant recovery, recycle, evacuate, and recharge machine. It can be used for multiple refrigerants. The portable machine’s microprocessor-controlled functions prompt the user through programming and signal preventive maintenance. The float chamber auto adjusts from liquid to vapor. The lockout panel prevents mixing of refrigerants. The heavy-duty filter drier removes moisture and acid from the refrigerant; it can handle 300 pounds between changeovers. The Promax® Cube™ refrigerant-recovery machine is capable of recovering both liquid and vapor refrigerant. The machine has a 1/3-hp, single-cylinder oil-less compressor.

Spectronics Corp.’s (www.spectroline.com) Optimax 400 leak-detection flashlight features power comparable to high-intensity, 150-W lamps, and an inspection range of up to 25 feet.

SuperCool’s (www.supercoolsliderule.com) Slide Rule is an R-22 and R-410A charging and duct calculator that performs superheat, subcooling, and duct calculations in one tool. Fixed meter-device charging is provided for R-22 and R-410A. TXV charging is also provided for R-22 and R-410A.

Superior Signal Co. LLC (www.superiorsignal.com) introduced the AccuTrak® VPE-GN ultrasonic leak detector with a 9 ½-inch gooseneck. The unit is sensitive to the ultrasonic sound of a turbulent gas leak. Using a technology called heterodyning, it translates the sound to a lower frequency which human ears can interpret, said the manufacturer. The device maintains the original sound characteristics, making it possible to distinguish leaks from other background sounds. The leak detector is designed to pinpoint leaks in air conditioning and refrigeration systems, acknowledging present air, vacuum, refrigerant, or gas leaks.

Testo AG’s (www.testo.com) testo 316-3 is a refrigerant-leak detector that includes a sensor head, transport case, calibration certificate, batteries, and a filter. It has one-button operation and the high/low sensitivity adjustment allows users to pinpoint the leak source. The company also offers the testo 310 and testo 320. The 310 is a residential combustion analyzer with a built-in condensate trap. The 320 is a high-definition combustion analyzer for both residential and commercial applications. There are many features with the 320, including its full-color, high-definition screen.

Universal Enterprises Inc. (www.ueitest.com) introduced the DRS220 digital refrigerant scale, which measures weight in both metric and English units, is programmable, and has a built-in alarm to indicate a programmed threshold has been exceeded.
