Which blast pot control system saves you 10% of your abrasive?

 

The secret to holding onto your pressure and your profits is a good control system.

Although the Pressure Release System may be the most common, the truth is, popular doesn't always mean profitable.

In nearly every application the Pressure Hold is the better choice.

Whats the difference?

The Pressure Release System is when you release the Deadman handle that's attached to your Blast Hose, and all the pressure in the Blast Pot, is released back into the atmosphere. This uses a Micro Combo Valve on the blast pot.

Pressure Hold Systems is when you release the Deadman handle, and the Air Valve and Media Valve both close, retaining both pressure and abrasive. This uses a Schmidt Thompson Valve.

When should you use each?

Pressure Hold systems are best for jobs where you are:

  1. Constantly starting and stopping blasting.
  2. Involved in high production blasting.
  3. Doing Spot Blasting and moving from one part of your surface to another.
  4. Running long lengths of hose.

In these situations, we would always recommend you use a Pressure Hold System. The Thompson Valve from Schmidt is the superior product for Pressure Hold Systems. We've found that using a Thompson Valve will save contractors about 10% of their abrasive costs, this is because unlike the Pressure Release System, the Thompson Valve holds the air and the abrasive inside the blast pot. This means you dont waste abrasive every single time you release the deadman control which pressures down the pot.

A pressure release system DOES make sense when you find your blasters are constantly running out of abrasive. In this case, a pressure release system coupled with an overhead hopper is a great way to automate the refilling of blast pots.
