Description

The Schmidt® 6.5 Blast Pot is available in several configurations… Electric or Pneumatic Controls In the USA, many contractors prefer 12v electric deadman controls for 2 reasons:  1) Reduces chances of control system freeze-up in cold weather.  2)  Faster deadman response – especially when using over 100′ of hose – makes for safer operation. Valve Types (Pressure-hold vs. Pressure-release) TeraValve™ and Thompson® Valve These systems are ‘pressure hold’, which will substantially shorten the time that blasting will start after actuating the deadman.  The TeraValve is the latest generation, and offers some important advantages while costing less. Pressure-hold technology can save up to 15% on abrasive consumption when doing spot blasting, versus a pressure-release system. Combo/MicroValve™ This system is “pressure release”, which means when you release the deadman, the pot will depressurize.  The Combo/Micro valve system has the same fine metering control as the pressure-hold valves and is a lower initial investment. Note:  In blastroom applications with an overhead hopper to refill blast pots, you can add a Combo valve to the pressure-hold system.  This hybrid system (called Remote Abrasive Refill or Remote Depressurization) uses a separate push-button to enable the operator to remotely depressurize the pot, allowing automatic refilling from the storage hopper.  This combines the best features of both pressure-hold and pressure-release techologies, saving operator time.
