Why use solvent recyclers?

Reduced Dependency on Virgin Solvents:

By recycling solvents, businesses can reduce their reliance on virgin (new) solvent purchases. This can be particularly advantageous during supply chain disruptions or fluctuations in solvent prices.

Environmental Benefits:

By recycling solvents, businesses can minimize their environmental impact. Instead of disposing of used solvent, which can be harmful to the environment if not handled properly, solvent recyclers help reduce hazardous waste generation and promote sustainability.

Cost Savings:

Solvents can be expensive, especially when used in large quantities for industrial processes. Solvent recyclers allow businesses to reclaim and reuse solvent that would otherwise be discarded as waste. This significantly reduces solvent purchase and disposal costs over time.

Shop air knowledge

Q1.What is contaminated shop air?
A: Air containing moisture, liquid water, rust particles, and/or air compressor oil.

Q1a.Why is it bad?
A: Along with causing problems to our equipment, these pollutants can find their way into your next paint job.

Q2.How can compressor oil get into a gun washer?
A: The pistons inside an air compressor ride up and down on rings just as they do inside a car engine.

Over time, these rings(shown below) wear out.
As they wear, they will continue to lose their ability to seal properly.
When the wear becomes excessive, the compressor’s lubricating oil is allowed to escape into the shop’s compressed air, in a process called blow-by. Unfortunately, it doesn’t take much oil to ruin a paint job, producing an effect called “fisheye”.

Q2a.How to fix the bad air?
A:There is a quick way to get an idea if you have bad air, you will need a connected airline with coupler, an air fitting, and white cloth.
Carefully insert the air fitting into the coupler, directing the outflow of air into the white cloth for a second. Examine the white cloth,
and look for the evidence of wetness, dirt, or oil stains.

A positive indication here means we have issues with our shop air supply. We recommend a compressor or air filter technician visit the shop and offer their opinion on corrective actions.

Can the URS 500 be used for recycling Acetone?

Yes, we recommend using the lowest setting here, or 90C, which can also produce

Clean solvent with less than 25 grams per liter VOC content.

Can I use the recycler to get rid of old or a large amount of waste paint?

No, it is not designed for this, and we recommend having it hauled away by a licensed waste hauler.

I have drums or pails of solvent that have been sitting around for a long time. Can I recycle this?

While you may be able to recycle it, the reclaimed solvent may not have much value, and for a couple of reasons.

Over time, the solvents and coatings can break down into unwanted compounds. Further, if the containers are not sealed properly, the more valuable

Solvent components have evaporated away. We strongly recommend that old solvent waste be disposed of properly, and freshly generated wastes be recycled.

My solvent is coming out cloudy or white, what is causing this?

This is the presence of water in a miscible solvent, meaning the two readily blend together.

Water finds its way into a waste stream in these ways:

A person pours water into the solvent drum.

A person mixes their solvent and water paint waste and pours this into the drum.

The drum is stored outside and accumulates rain.

The drum is not sealed. Being exposed to air, it will collect condensation.

Is there anything I can do with my recycled cloudy solvent?

You may consider adding methanol to clear it up, provided methanol will not affect the intended use of the solvent.

Do Uni-ram recyclers use diathermic heating oil or refrigerant?

No, our machines are solid state, requiring no oil change-outs, ever.

They are also air cooled, removing the need for refrigerant cooling.

Spray Gun Cleaner Technical Issue

PROBLEM	CAUSE	ACTION STEPS
Unit is plugged in, all the lights on the Panel are Off.	Power is not getting to the unit.	Reset breaker or replace fuse. If power is still not getting to the unit, call a Qualified Service Technician. Ensure that the unit is the only device on a circuit with sufficient capacity.
Unit is plugged in, “READY(L)” / “READY(H)” lights are On, Heat light fails to come on when “ON” button is pressed.	Power board or fuse not functioning.	Call Uni-ram Service
Recycled solvent is not clear	1) The solvent is react- ing chemically.	1) Lower Termperature Set Point following Operating Procedure 4 in Manual
	2) The solvent flow path is dirty. One cause is overfilling the distillation tank.	2) To clean the path, follow Service Pro- cedure 2 and then recycle 3 gal of clean solvent.
	3) Orange colour due to rust in receiving pail.	3) Place a jar under outlet tube and capture some solvent. If the solvent is clear, replace the pail with a non-corrosive one.
	4) Milky colour due to presence of water.	4) Eliminate source of water in solvent.
Dirty solvent remains in Dis- tillation Tank after recycling Note: 1/8 Gal (500 ml) of re- cycled solvent is expected due to condensation.	1) Poor heat transfer due to dirt and debris left in the tank.	1) Clean the tank, replace the Liner Bag, recycle with pure solvent to test. If suc- cessfull, the problem is due to a dirty tank, debris left in the tank or the solvent is too contaminated. Adjust accordingly. Follow Operating Procedures closely. If the level of contamination is too high, recycle more often.

	2) Boiling point of solvent is above Tem- perature Set Point.	2) Raise the Temperature Set Point and repeat the recycling operation.The Tem- perature Set Point should be the BP of pure solvent (as determined from the MSDS or other source) plus 45°C (113°F) to allow for contamination. If the boiing point is above the maximum Temperature Set Point for your model (200°C), dirty solvent cannot be recycled in this unit.
	3) The Auto Shut Off system is shutting the unit off too soon.	3) Run SETUP and over-ride the auto SHUT-OFF. Select a time period long enough to recycle the solvent. The heater will stay on for this duration. Repeat the recycling operation.
Liner Bag sticks		Turn unit on for 5 mininutes and lift out bag while it is still warm.
Solvent vapor leaks from the Lid Gasket	1) Lid Gasket has excessive wear as indicated by cracks, shrinkage, hardness etc	1) Replace the Lid Gasket (See Manual Operating Procedure 11).
	2) Solvent flow path is blocked.	2) Follow Manual Service Procedure 2.
	3) Lid Tension not adequate	3) Follow Manual Service Procedure 4.
	3) The Lid is not seated correctly.	3) Follow Manual Service Procedure 5.
	4) The temperature SET-PT too high, re- sulting in excessively high solvent vapour pressure	4) Reduce the Temperature Set Point and repeat the recycling operation. If success- ful, continue to recycle using the lower Temperature Set Point.
Sections on Bag are brown and thin due to High Temperature	1) Use of inferior low temperature bag.	1) Use new genuine Uni-ram high tempera- ture Liner Bag and recycle.
	2) Temperature Set Point is too high.	2) Reduce the Temperature Set Point and repeat the recycling operation. If success- ful, continue to recycle using the lower Temperature Set Point.
The computer appears to be operating erratically.	The computer may require re-booting.	Disconnect the power supply for 30 sec- onds. Restore power and operate unit.
Residue (puck) in Tank is too wet.	1) Not enough heat to vapourize the solvent.	1) Raise the Temperature Set Point
	2) Residue cannot be dried completely due to its composition.	2) None.

MESSAGE	POSSIBLE CAUSE	ACTION
BOILING TIME OUT (No change in vapour tempera- ture was detected within the set time limit, usually 45 minutes)	• Boiling did not occur within the set time limit because the dirty solvent mixture is too contami- nated • Blockage in the solvent f ow path, most likely with leakage of solvent at the lid	• Run SETUP, raise the Temper- ature Set Point and repeat the recycling operation. See Trouble- shooting Guide (“Dirty solvent remains in Distillation Tank after recycling’).
READY TIME OUT	Recycling was not completed within 9 hours and/or dirty sol- vent remains in the Tank.	If dirty solvent remains in the Tank, see the Troubleshooting Guide.
RESET OCCURRED	The heater has stopped and the computer has reset due to a power interruption or drop in voltage.	Press the “STOP” button to restore the unit to the beginning of a new cycle. The display will read: “READY-SP = XXX° C”.
CONDSR OVER-HEAT	Over-heating occurred at the Condenser.	The Condenser is dirty or the Fan stopped for another reason (see below). Clean the Con- denser. When the Fan Motor has recovered (4-5 min), this mes- sage will disappear and normal operation will resume.
CHECK FAN	Appears 10 min after the mes- sage above if the problem is	Clean the Condenser. Run TEST MODE to check for defective fan motor. If necessary, check for a loose fan blade or blown fuse (see next section).
	a loose fan blade, blown fuse (F3 or F4) or other fan-related problem. Also appears if the condenser is dirty.
CHK HEATER FUSES	Appears if the computer does not detect a rise in tank temperature after 15 minutes.	There may be a short circuit in the Heater circuit causing fuse F3 and/or F4 to blow or poor electrical contact in the Heater circuit. Check circuit condition with a tester. Correct as required.
WARNING! VERY IMPORTANT! IF TRIAC IS FAULTY, DISCONTINUE USE IMMEDIATELY!
CHK HEATER TRIAC	Short circuit in the TRIAC (a switching transistor that controls heater power, located on the Power Control Board).	To confi rm, fi rst disconnect and re-connect the power supply. If the Distillation Tank becomes hot to the touch and both the Heat Light and the Fan Light are off, the TRIAC is defective. Disconnect the power supply immediately and do not use again until the Power Control Board has been replaced
