Below are Engineered Fluids standard guidelines on sample testing and reprocessing requirements. Please contact Support@engineeredfluids.com for further information.
How to Send Test Sample to Engineered Fluids:
-
Sample must be provided to Engineered Fluids to determine if the fluid is reprocessable.
-
When preparing coolant samples for analysis, it is essential to avoid external sources of contamination. Please do not use a funnel to add fluid to the sample bottle.
-
The sample bottle should be made of borosilicate glass, with a polypropylene-lined cap.
-
Gathering the sample:
-
An unused length of White 1/4 IN diameter white PEX tubing, length of tube should be greater than the deepest part of the tank (Pex tubing is readily available at most large retail hardware stores) and a Sample Container should be accessible.
-
If only one sample is being taken, please ensure the sample is taken from the deepest part of the tank. This is highly important specifically when dealing with water contamination. If a sample is taken only from the top of the tank it will result in a sample showing far less water contamination than is present and this could result in a false positive for reprocessing.
-
To take the sample, use the cut length of the clean PEX tube and hold the tube at the top allowing your finger to be able to seal the top "Vent/Hole".
-
Place the end of the tube into the deepest part of the tank, ensuring the tube physically hits the bottom of the tank. DO NOT SEAL VENT HOLE UNTIL NEXT STEP
-
Allow fluid to fill the tube to the fluid level in the tank (This takes 1-3 seconds) and place your finger over the vent hole in the tube above the fluid level. Ensure your finger is fully covering the vent hole. This will create a suction allowing the fluid to be transferred out of the tank and into the sample bottle.
-
Place the end of the tube into the sample bottle and uncap your finger from the top of the tube.
-
Fluid will drain into the sample bottle.
-
Repeat these steps until 1/2 Liter of fluid is in the sample bottle. The bottle should have a minimum of 25mm of air left at the top to allow the sample to cool to room temperature before sealing. This is crucial to avoid any spillage or bottle burst during transport.
-
Lightly cap the bottle, DO NOT SEAL THE BOTTLE YET, and wait until the fluid reaches room temperature, once the sample is at room temperature fully open the cap for a few moments to allow the air pressure to equalize and then close the bottle.
-
Each fluid sample must be given a unique identifying code to allow EF to identify each sample. The samples should be marked with a label or wax pencil. Sharpie pens and similar inks will not adhere to a bottle that has coolant on it. We recommend using a 2-part ID like EF-01, EF-02, …. EF-10
-
2-3 Letter abbreviation of company name or customer name followed by a dash and then,
-
Numeric labeling of sample bottles (ex. 01, 02, 03, 11, 12, 13, etc.)
-
Information required on a separate sheet included in the shipment with the sample bottles. If multiple samples are sent items 1-3, below, only have to be listed once. Items 4-x must be listed for each sample sent:
-
Company name and company abbreviation used on sample bottle.
-
Contact Name
-
Contact Email and Phone Number
-
Fluid Type (ex. EC-xxx, BC-888, etc.)
-
Numeric Sample Bottle Label (ex. 01, 02, 03, 11, 12, 13, etc.)
-
Date Sample was taken.
-
Location sample was taken within the system (ex. Bottom of Tank #1, Bottom of Tote #4)
-
Potential or Known contaminants.
-
Before shipping each cap should be tightened and securely sealed with 2-3 Complete wraps of electrical tape to prevent loosening and spillage during transport.
If the Sample Tests Negative for Toxic Contamination
-
Engineered Fluids will provide the Customer with a copy of the test results and discuss the nature of the contamination results with the Customer.
-
Engineered Fluids will provide a recommendation and quotation for the necessary reprocessing.
-
Customer should then pump out the Coolant from the contaminated system into the original shipping containers.
-
Either the customer or Engineered Fluids can arrange shipping to the EF Tyler facility at Customer expense
-
Engineered Fluids will reprocess the fluid and place the reprocessed fluid into new containers.
If the Sample Test Positive for Toxic Contamination
-
Engineered Fluids will provide the Customer with a copy of the test results and discuss the nature of the contamination results with the Customer.
-
Engineered Fluids will take the appropriate actions to assist customers in arranging for either the safe destruction or third-party recycling of the contaminated coolants.
-
Engineered Fluids will arrange with the Customer for their purchase of empty shipping containers to the Customer site and loading instructions for the Coolants.
-
Customer will be responsible for transferring the fluid to the containers and readying them for shipping in accordance with Engineered Fluids instructions:
-
Engineered Fluids will organize the shipping of the full containers to the appropriate third-party recycling or disposal facility at the customer’s cost.
-
The contents of all containers will be tested again upon arrival at the recycling or disposal facility to validate the earlier test results and ensure compliance with handling and safety requirements as well as to assess any additional costs that may be the responsibility of the Customer.
-
The coolants will be recycled or disposed of at customers' cost in accordance with all local, state, and federal laws.
