Recovery
Recycling
Recharging

Fully automatic function lets you recover, vacuum, leak test, charge, and then walk away.

Combines simple operation with superior accuracy
The Cool-Tech 34700Z 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 AC 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 12 to 15 pounds 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!

Electronic Scale — The scale is mounted internally for protection and has a dampening mechanism that protects against impact shocks, such as movement over rough surfaces. The scale weighs recovered refrigerant and charges by weight for greatest accuracy.

Internal Storage Vessel — Refrigerant is recovered into and charged out of this vessel, which is permanently mounted to the electronic scale for continuing reliability.

Internal Manifold — A Robinair exclusive, this block manifold contains all the solenoids that control refrigerant flow in and out of the unit, reducing the possibility of leaking connections and eliminating the need to operate panel valves.

Best of all, it’s easy to use!

Ergonomic Design — The cabinet is easy to maneuver between service bays and position near the vehicle.

Large Gauges — The high and low side gauges are mounted at an angle that’s easy to see, and they’re a full 4" in diameter.

Features that speed service:
• 6 CFM vacuum pump for fast, thorough pull-down.
• Heavy-duty compressor pulls from both high and low sides during recovery.
• Single pass recycling meets SAE specs.
• Oil injector lets you add system oil in seconds.

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 12 to 15 pounds of refrigerant in an internal vessel, and even signals when it's time to change the supply tank so no monitoring is needed. Uses a 30 or 50 pound disposable source tank.

Automatic Air Purge - Eliminates damaging air without any monitoring of gauges or opening of valves.

Internal Manifold - A Robinair exclusive, this block manifold contains all the solenoids that control refrigerant flow, reducing the possibility of leaking connections.

Alpha-Numeric Display - The scrolling display shows messages so it's clear what your choices are or what needs to be done. you can select English, French, German or Spanish, as well as pounds or kilograms.

Best of all, it's easy to use!

Ergonomic Design - The Cool-Tech 700 cabinet is easy to maneuver between service bays and to position near the vehicle. With the control panel facing the vehicle as you move the unit, you can clearly see the best orientation.

Large Gauges - The manifold high and low side gauges are mounted at an angle that's easy to see from under the hood, and they're a full 4" in diameter.

Model 348002K Cool-Tech Dual 2K

Use the same unit for both R-12 and R-134a and save space in your shop. You can switch from one refrigerant to the other at the touch of a button. The 348002K comes with two built-in manifolds, two tanks, two compressors and two electronic scales, so there's no need to clear or switch tanks. It takes up less room than two individual units and automatic operation makes it easy for any technician to use.

Automatic operation frees you up to do other service work!

Microprocessor with Scrolling Display - Controls all functions including evacuation time and recharging amount, plus signals when it's time to change the filter-drier, pump, oil, etc. Alpha-numeric display shows messages which are easy to understand.

Automatic Air Purge - Any air in the tanks is automatically purged as needed to prevent the problems caused by air in a vehicle's A/C system; there are no gauges to monitor and never need recertification.

Electronic Scale - Automatically shuts off the unit when the programmed amount of refrigerant has been recharged, also provides tank overfill protection and monitors the amount of refrigerant recovered. Storage vessels are permanently mounted and never need recertification.

Speeds service for increased profitability!

Single Hook-Up - All service work is done in one fast, continuous operation through the one hook-up to the vehicle.

Heavy Duty Compressor - Pulls refrigerant from both the high and low sides of the A/C system for fastest recovery; compressor return oil separator keeps the compressor lubricated for long-life, proper operation.

6 CFM Vacuum Pump - Powerful Cool-Tech vacuum pump has the power and capacity to pull down quickly and dehydrate thoroughly so you know the system is ready for a recharge.

Super-Fast Charging - A typical auto recharge takes a minute or less.

Oil-Injection - Lets you add system oil in just seconds while the unit is in a vacuum.
