QUESTION; How can you be so sure that your machine is safe?

ANSWER; There are dangers in using a closed system and in using a flammable solvent. There are not many systems that are completely safe. It is very important that you learn what the risk are and learn how to prevent an accident from occurring.

In regards to what steps we have taken to make a safe product.

  1. First and foremost, there is no safer way to recover a flammable volatile solvent than to drop its temperature. And that is the process we use for recovery.

  2. Butane is not the only solvent that can be used in a tamisium. A tamisium allows you to choose any solvent as your primary solvent as long as it has a higher boiling point, creating lower pressures than butane. Butane is the only solvent that allows you to extract out very volatile oils and then simply drop its temperature to recover it.

  3. We offer ASME and Non ASME systems that are certified safe for use in every state. ASME - American Society for Mechanical Engineers.

  4. All parts used are industry standard parts that have been used safely for years and have all the proper safety certifications. Cut sheets are provided on the Learn More Page.

  5. All hydraulic expansion and pressures are accounted for in the volumes of each tank greater than the temps and pressures the system is designed to operate at and the necessary buffer zones were created. The entire system and process was designed around solvent expansion.

  6. In the event that someone decides to push the tanks beyond their design limits a VRVI or Vented Relief Valve Inline has been placed on the suspect tanks to vent off pressure to a safe location via the inline connection.

  7. Maximum temps of 120F have been set for the heating system. And a lockout has been placed on the programming so that it cannot be changed by accident.

  8. A thermal fuse has been placed on all heating jackets to shut off power if unsafe temperatures are detected by the sensor.

  9. Accidental over heating is eliminated by use of solid state circuitry in the heating control. This also avoids sparks and failures in mechanical parts.

  10. Wafer Valves that seal off the larger EXtractor Tank so that the column can be removed and refilled quickly and safely.

    You would have to deliberately set the system up for failure and even then your fail safes and safety precautions would protect be in effect.


Things to consider:

Overfilling a tank containing a liquid could cause a rupture and expel all the contents at once. It is imperative that you read the manual and know how to fill a tank correctly in a closed system. Should this tank rupture the contents would be expelled instantly. It this were to happen and you did not follow safe protocol your contents could ignite if the solvent is flammable and it finds an ignition source. Preventing an accident from occurring is possible if all the safety guidelines are followed. You must understand and therefore it is our duty to teach you how to do this safely but it is up to you to read the instructions and adhere to the safe use of any apparatus you choose to use.

What is a flame? A flame is a chemical reaction. A chemical reaction requires a catalyst. In this case a spark or another flame. To have a reaction you need chemicals. In this example, we have the butane, and we need another one, oxygen in the air. As long as the butane remains in the closed tank you will not have to worry about it igniting because there is not enough oxygen in the tank. The reaction that would occur is the hydrogen atom and the carbon atom in the butane molecule would separate to bond with the oxygen in the air. Producing H2O and CO2, water and carbon dioxide. For this to occur we need an adequate amount of them. We either need to pump oxygen into the mixture of liquid butane, or we need to vaporize the butane into the air. The way I see an explosion is the rapid expansion created by this reaction combined with the butane attempting to expand out to the oxygen in the air. As the air molecules begin to separate and recombine more space is required to hold them and you get a concussion, via exploding or imploding. I would assume the sonic boom of this rapid expansion is what you hear. Air for a moment becomes a solid force to be reckoned with. Flame colors change when the mixture of chemicals change. More or less oxygen for example. So does the heat. More oxygen, more heat.

I am not trying to scare anyone. On the contrary. I am trying to convey that to make a safe system, you have to have an understanding of the nature of the chemicals you work with. Science is not about opening doors to find out what is on the other side. It is about using science as a tool to peer through the keyhole whereby we eliminate the risk. How much we lessen that risk is a measure of how advanced our science is. The ability to see more doors is our genius. The ability to survive is our intelligence. Show me an extremist that is living and I will show you an engineer or really lucky guy. I would personally rely on my understanding of how danger occurs so that I can operate safely. We are here to answer questions and advise everyone to look before you leap. A policy that is not in operation with most equipment you could use. Please take advantage.
