Pulsair ft-2D pneumatic controller
This is for a used Pulsair Pneumatic Controller, model FT-2D. This item is used but appears to be in good working condition. Here is what Pulsair says about the product:
Tanks attached to an FT-2 controller do not have to be of equal size. For that matter, one tank could have a flat bottom; while the second, a V or cone bottom tank, which requires only one accumulator plate. When tanks are not of equal size or shape, it may be necessary to adjust the pulse rate when switching from one tank to the other in order to maximize effectiveness. The FT-2 is most ideally suited for two tanks of equal size and shape. However, having two different tank configurations does not pose any great degree of difficulty.
PULSAIR offers the FT-2D, an FT-2 with an additional feature. The FT-2D increases the FT-2's capability with the additional control option of mixing both tanks simultaneously. The FT-2D was designed to meet the needs of Shell Oil in Carson, CA. Shell wanted to operate two tanks simultaneously with one controller. Since the tanks had different liquid levels, PULSAIR decided to make a controller with one pulse frequency adjustment and two air pressure regulators. The FT-2D will operate both tanks simultaneously. The two tank share the same dwell setting (pulse frequency) but have separate regulators for adjusting the injection pressure. Since its conception, the FT-2D has been sold to Shell, Exxon Chemical, Esso, Castrol, Texaco and OMG Mooney.
The FT-2D system actuates two injection valves simultaneously, therefore it requires twice the air (SCFM) of an FT-2. Because the demand for air is increased, the supply piping and filter are larger than an FT-2 system. Therefore, the FT-2D costs more than the FT-2. However, the cost is outweighed by the increased tank throughput created by simultaneous mixing.
FT controllers are entirely pneumatically operated, and located close to the tanks. Once mixing parameters are set, no further control setting other than turning it on or off are required. Remote control capability for timing functions is available.
FT systems are designed to mix tanks of 3,000 gallons or more, and are easily configured to control the mixing requirements for tanks of 1,000,000 gallons or more with the addition of extra injection valves and accumulator plates.
Because FT systems are pneumatically controlled and contain no electrical components, they meet all the requirements for hazardous environments, including Class 1, Division 1 criteria and international IP-65.
