Combines simple operation with superior accuracy. The Cool-Tech 34788 recovers, recycles, evacuates, leak tests, and recharges R-134a quickly and accurately. Automatic operation means less attention is needed!

  • Automatic Function — With this new option, you can program the unit to
    recover, vacuum, leak test, charge, and then walk away without having to operate panel valves.
  • Vacuum Leak Test — Will monitor the vacuum level after an evacuation, and
    inform the technician of a possible leak in the vehicle’s A/C system.
  • Automatic Refrigerant Refill — With this latest advance, you never have to
    stop in the middle of a job to change refrigerant tanks. The unit maintains a user
    selectable amount of refrigerant in an internal vessel, and signals when it’s time
    to change the supply tank, so no monitoring is required.
  • Automatic Air Purge — Eliminates damaging air without any monitoring of
    gauges or opening of valves.
  • Automatic Oil Drain — The unit automatically drains system oil captured during
    recovery, and the display reminds you to empty the bottle. Graduations on the
    container clearly show you how much oil needs to be replaced.
  • Refrigerant Charging — Has never been this easy. Select a charge mode from
    either the high side, low side, or both. Accuracy features eliminate guesswork!
  • Refrigerant Management Systems—New and improved, system displays
    refrigerant use and monitors remaining fi lter life. Prompts appear when 1/3 of
    filter life remains.
  • Vacuum Function — Defaults to 15 minutes, but is programmable up to 99
    minutes. Remaining vacuum time is displayed on the screen.

In June 2005, the Society of Automotive Engineers (SAE) started a research program to reduce the emissions of R-134a. The program, called I-MAC (Improved Mobile Air Conditioning), was tasked with cost effectively improving R-134a systems while reducing refrigerant emissions. The I-MAC members have pledged to design smaller systems with fewer leak points and improve service equipment. As a result of this program, the SAE recently approved tighter standards for automotive A/C recovery, recycle and recharge equipment. The new standard, SAE J-2788 requires that all service equipment manufactured after November 1, 2007, must recover 95 percent of the refrigerant and recharge to within 1/2 ounce.

How will this affect ME?
Up until a couple of years ago, R-134a was cheap and plentiful. Today it’s a different storyrefrigerant is much more expensive and not always available. The Robinair 34788 recovers up to 20 percent more refrigerant, which means it will cost less to recharge the system. The best charge accuracy that could be claimed by older generation service machines is +/- 1 ounce, a 3 percent error on a two-pound system. That same charge accuracy on a 14-ounce system is over twice the error (7 percent).

Early R-134a systems could still provide some cabin cooling when they were 4-6 ounces (12- 18 percent) low on refrigerant. However, new designs are so efficient, they do not have reserve refrigerant, and charge accuracy will be critical. In the shop, the Robinair 34788 will recharge the vehicle to within 1/2 ounce of the charge capacity, and you will avoid the dreaded “call back”. As the shop owner, you will realize more profits per service by recovering more refrigerant and charging less. The savings will be obvious.

I purchased this unit back in June 2009 and have nothing but good things to say about it and NTW. Fast no problem delivery. Every thing as stated at time of purchase. Very easy to set up. I was very worried about the use of it and performance. But has not given me any problems at all as of yet, March 2010. I would highly recommend getting this unit over the other non automatic model. You can just set everything as stated and let it go and then when performance testing vehicle for the first time it works correctly. Never had to adjust freon in vehicle at all, works great. No more guessing or wasting freon again. I had talked to other local shops and found some using this or non automatic model and I decided to go with automatic. Glad I did, like the saying goes, "Set it and forget it". Next step is just done no ifs ands or buts about it. Ready for customer delivery.
