Control

Altitude Control Systems

Even the most crude of altitude simulation systems have some way of being adjusted, but this may be a long way from ACT’s definition of being “Controlled”

At Altitude Control Technologies the electronic controller is the brain of the entire system. It’s capabilities and sophistication has a direct effect on overall performance and the customer’s satisfaction of their altitude system.

So what does “Controlled” actually mean?….

At the very least it should include the following:

  • Switch entire system on and off with one convenient button.
    • No need to run round the mechanical room, turning every air unit on and then standing there adjusting every flow rate.
  • You enter your desired altitude in Feet or Meters
    • Not in Oxygen %. Ever see a mountain’s height listed in % oxygen?
  • The room is brought quickly to the target altitude using all available equipment.
  • FillRate
  • Altitude is automatically stabilized to your chosen Set Point
    • No running back-and-forth adjusting air units to get what you want.
  • The altitude can’t accidentally get dangerously high.
    • More than one level of action to limit or control the altitude 

For any sort of scientific or other professional use it should also include the following:

  • Barometric pressure monitored and included in altitude calculations.
    • Fail to include this and you’re not calculating true effective altitude. A simple oxygen conversion could be off by thousands of feet up or down..
  • The simulated altitude is clearly displayed, in Feet or Meters.
    • Effective altitude is based on the partial pressure of oxygen
    • Oxygen % is only half the story. You need to consider the barometric pressure too.
  • Intelligent triggering of an array of control items.
    • The system should adjust accordingly to a variety of factors including maximizing altitude gain, increasing air-exchange, or energy conservation
  • CO2 is monitored and responded to.
    • CO2 is a great indicator of overall air quality.
    • As CO2 increases idle air separation units should be triggered, fans powered on and ventilation increased to protect air quality.
  • Power-saving: Excess equipment is automatically turned off when the occupancy is detected as being low.
    • The room may be kept at altitude, but that doesn’t mean all the equipment needs to be running all the time.
  • Idle equipment is automatically turned back on when it’s detected that the room is occupied.
    • Increasing air exchange early means the CO2 never gets too high and the air stays fresh.
  • Sounding alarms for a variety of conditions you’d want to know about.
    • Including excessive CO2, Altitude, O2
    • Sensor error

With ACT’s Touchscreen Controller it ALSO means:

  • Automatic sensor calibration
  • Adjust the target altitude by as little as 1′ or 1m
  • Two 10-year ultra-stable O2 sensors for increased accuracy and for identifying when a calibration is needed
  • TRUE altitude, by constantly controlling the partial pressure of oxygen
  • Second and even third remote displays.
  • Air Separation equipment triggered sequentially with a 0.5 second delay between each device to avoid excessive start-up surge as happens when multiple air units are triggered at once.
  • Remote access and control anywhere there’s internet,…. even on your phone
  • Being able to choose a high-performance mode, power-saving mode, or just monitor the room without any equipment running
  • A screen which shows some or all the information you might desire including a screen which only shows the effective altitude you’re at
  • A screen dimmer control, or a dedicated dark nighttime screen
  • Oxygen levels automatically maintained in accordance with NFPA standards. ACT’s system is the only controller to meet this standard.
