The CoolTech RO16900 refrigerant identifier from Robinair provides technicians with accurate refrigerant purity and protection against equipment and air conditioning system damage that can result from contamination.  It provides a “pass” reading if the concentration is 98% or greater by weight of a single refrigerant. Less than that is a fail result that calls for additional service.

The CoolTech RO16900 comes complete with sample hoses and adapters as well as power adapters for battery or AC power and a storage case that keeps them all safe and organized. Just what pro’s expect from their professional mechanics tools.

Readings are delivered on the unit’s control panel that consists of a two-line, 16-character, digital display nd two pushbutton switches. The display conveys analysis results and instructions to the user. The switches provide a means for the user to communicate with the instrument microprocessor during use. It’s beautifully simple. It even has a convenient hook on the top so it can be hung near the immediate work area and there’s an optional bracket that affixes to the Robinair 34700 and other recovery/recycling/recharging units.

The 16900 refrigerant identifier is so easy to use. Plug it in, give it a couple minutes to warm up (the first time you use it, set the elevation of your area - you can get the elevation of your town from a simple Google or Yahoo search). From that point the identifier prompts the user every step of the way. It’s prompts are as simple as:  “connect the sample hose” so there’s no standing there confused trying to determine the next step.

This Robinair identifier delivers a

“PASS” when a sample is detected to have 98% or greater of R-12 or R-134a by weight. The refrigerant type and air concentration are also displayed.

“FAIL” when a sample is detected to be a blend of R-12 and R-134a refrigerants with neither R-12 or R-134a having 98% or greater concentration. The weight percentages of R-12, R-134a, and air are displayed;

“FAIL CONTAMINATED” when unknown refrigerant types, such as R-22 or hydrocarbons, have been detected in concentrations of 4% or greater by weight. No weight concentrations of refrigerants or air are provided in this mode; or

“NO REFRIGERANT—CHK HOSE CONN” when a sample is detected containing 90% or greater air by weight. This condition usually occurs when the R-134a sample hose coupler has not been opened, the sample hose has not been connected to the sample source, or if there is no refrigerant present in the sample source.

The  16900 is a must for air conditioning technicians to have among their selection of required mechanics tools.

The RO40134A R-134a Side Wheel Manifold with Hoses is designed so that all three lower fittings are connected to each other by internal passages.  Separate passages from the low and high side fittings to their respective gauges give you pressure and vacuum readings whether the hand-wheels are open or closed.  For your convenience and safety, hand-wheels and gauges are color-coded with the blue compound gauge on the left or low side, and the red pressure gauge on the high or right side.  Field service couplers are provided to access the vehicle’s service ports.  The service coupler should be in the closed position before connecting to the external fitting on the vehicle.  To close, turn the handle counterclockwise until finger tight.  Place the service coupler on the external fitting.  Push in on the handle of the service coupler with your thumb, while pulling up on the sleeve, until it bottoms on the external fitting; then release.  Check to see if it is correctly seated by pulling up on the service coupler.  For maximum flow, turn the handle clockwise until it stops.  And these are the proper procedures to connecting the service field couplers to the RO40134A R-134a Side Wheel Manifold.

There was a time, just a couple years ago in fact, that R-134a refrigerant was cheap and easy to get.  A/C pro’s know that’s not the case today and probably won’t be again.  Used to be that accuracy mattered but it wasn’t really critical like it is now.  Older automotive air conditioning systems were larger and components themselves could actually serve as a reservoir for refrigerant. That means that even a system less than fully charged could still supply a vehicle’s interior with cooling to a resonable degree. A charge accuracy of within a couple ounces was sufficient. Today you need to reach a half ounce of accuracy to keep your customer cool, both physically and tempermentally.

The last thing you need on a busy hot day is a customer sweating and swearing because he’s only cooled him down to 99 degrees because you’re still using Grandpa’s mechanics tools. That’s going to cost you money in future business for a long time to come as well as having to deal with him at the moment.

Robinair has developed the A/C shop equipment to keep your customer satisfied and loyal. It’s the RO34788 recovery/recycling/recharging unit that delivers dependable green-friendly service and profitability for years into the future and tells your customer that you only use the very best mechanics tools available.  That’s a business builder in this day and in this green-conscious environment.

The RO34788 is not only good marketing, it’s a fast easy to use fully automatic unit that’s reliable and flexable to meet all your A/C recovery/recycling/recharging shop equipment needs. This Robinair unit meets the latest standards; it tells your customer you’re a quality shop; it recharges air conditioning units in under 30 minutes and it saves you money on expensive R-134a refergerant.

The Cool-Tech 34288 is fully compliant with SAE J2788 standards!  This is the way you recover refrigerant from a vehicle.  First you empty the oil drain bottle located on the right-hand side of the unit, if necessary, or make note of the current oil level.  Then you connect the high- and low-side hoses to the vehicle A/C system.  Open the coupler valves on the hoses.  Open the high- and low-side panel valves on the control panel.  Press the Recover button.  When the system has recovered to 0 PSI, the vacuum pump starts and runs until recovery is complete.  The unit then goes into an automatic oil drain—this may require 90 seconds to complete.  After the oil drain is complete, the display shows: Recover Complete; Recovered XX.XX LBS. (X.XX KG); Check Oil Bottle.  This is the way to evacuate the A/C system.  First you ensure that the service hoses are connected, and coupler valves are open.  Press Vacuum.  Then you press Start / Yes to accept the default evacuation time of 10 minutes, or enter the desired vacuum time using the number keys, and press Start / Yes.  The unit evacuates the A/C system and stops when the specified amount of time has elapsed.  Press Stop / No to pause the process.  Press Start / Yes to resume, or Stop / No again to exit.  Finally you are now ready to replenish the A/C system with new oil, if necessary, or to recharge the system with refrigerant.  These are some of the procedures you take to do a couple of the tasks that the Cool-Tech 34288 can do.  Missing the recharging procedures.

The rapidly growing green movement around the world offers opportunity to shop owners.The Society of Automotive Engineers has set standards for automotive air conditioning for recovery/recycling/recharging mechanics tools and every unit sold today must conform to those rigorous standards.

Recovery, recycling, and recharging units now must recover 95% of air conditioning refrigerant, recharge to within an accuracy margin of 1/2-oz and achieve recovery within a 1-oz margin.

The objective was to not only achieve these new standards but to be able to do so cost effectively. So, the standards were set and the technical people at Robinair went to work developing  recovery/recycling/recharging units that would accomplish those goals.  They did it!

The Robinair 34788; meets the rigorous demands of SAE J-2788 (the Society of Automotive Engineers standards) while at the same time delivering a trouble-free profitable professional mechanics tools investment that delivers green-friendly profits to shop owners for years to come.

In response to the rapidly growing environmentally-conscious green movement, the Society of Automotive Engineers determined that new standards must be established for automotive air conditioning mechanics tools for recovery/recycling/recharging. After a few years of research they determined to reduce R-134a emissions by reducing leak points and technology in air conditioning equipment.

The result of their efforts is called SAE J-2788 (Improved Mobil Air Conditioning) and required that all service equipment manufactured after November 1, 2007 must recover 95% of refrigerant and must recharge to within a 1/2-oz accuracy margin as well as a 1-oz recovery margin.

The objective was to not only achieve these new standards but to be able to do so cost effectively. So, the standards were set and the folks at Robinair went to work developing the recovery/recycling/recharging unit that could accomplish those goals. They got the job done.

They developed the Cool Tech 34288 and the Cool Tech 34788; two Robinair units that meet the demands of the SAE J-2788 while at the same time delivering a trouble-free, profitable A/C mechanics tools investment that delivers for years to come.

The Cool Tech 34788 is a fully-automatic unit that lets technicians quickly and efficiently do vacuum leak tests, refill refrigerant, purge air from the system, charge and manage refrigerant - AND get it done in 30 minutes or less.

The RO16600 is an Electronic Leak Detector used to detect refrigerant leaks in air conditioning and refrigeration systems.  It features a sensitivity selection switch which allows it to be used with CFC’s and HCFC’s at one setting and HFC’s at the other.  The RO16600 Electronic Leak Detector is able to detect leaks smaller than 1/2 ounce per year.  Other features include audible and visual leak indicators, a volume control, a threshold balancing control and a 16” gooseneck probe, which holds its position for one-handed operations.  When the unit is not being used, the probe wraps into a retaining clip on the back of the case.   The first time you use the RO16600 Electronic Leak Detector, install the batteries before turning on the unit.  4 “AA” alkaline batteries are included.  Remove the gooseneck probe from the retaining clip on the back of the leak detector case.  Turn the ON/OFF switch to ON.  Select the sensitivity level by sliding the switch to either the “1” setting or the “2” setting.  Adjust the balance.  Turn the BALANCE control up to a loud alarm sound, then turn it down until you hear a slow, steady ticking.  Begin searching for the leak.  The recommended scan rate is 2 inches per second with the sensing tip as close as possible to the area being searched.  Run the probe under tubing and check carefully around bends, fittings, and other typical leak points.  To pinpoint a leak, you may need to adjust the balance.  When you are near a concentration of refrigerant, the alarm tone will sound.  Keep the probe in the same position and turn the balance control down until you hear the ticking sound.  Then continue searching for the leak.  You may need to balance the unit several times if there is a large leak and refrigerant has accumulated.  If you find more than one leak, or if you suspect more than one, repair the larger leak or leaks first so pinpointing the smaller leak is easier.
