Professional installation optimization instead of "micro-digit jeopardy"...
You'll probably recognize this from your car: Thanks to speedometer and rpm display you can at any time precisely read the speed and performance of your vehicle and then adapt them according to the requirements.
It is only logical, that the scale values between zero and maximum displayed on the speedometer always more or less correspond to the car's performance.
Accordingly it would be absurd to integrate a speedometer with a fixed scale ranging from -600 to +2,400 km/h into a pick-up truck with a top speed of just about 160 km/h, when effectively only the range from 0 to 160 km/h is relevant.
With such a scale not only 95 % of the value range are completely useless, you would also have no chance of reliably adapting your speed to a certain readable velocity, because the teensiest movement of the speedometer needle directly connotes 50 km/h more speed!
Evidently, you as car buyer would not accept such nonsense! So why do it when picking your insulation drying unit?
Even today ammeters are still integrated in insulation dryers, arguing that this way the system construction could be adjusted, even though the use of an ammeter here equals that of the imaginary speedometer from our above car example:
With their wide span between extreme values in double figures ammeters give the impression, that the entire scale range must somehow be relevant for the drying process.
In fact, though, the decisive output range for an insulation dryer between "standstill" and "top speed" is restricted to less than one ampere and thus to only one to two scale steps on the ammeter. Which means that here too 95 % of the scale of values are of no avail.
As if that weren't enough:
In the everyday working conditions of an insulation dryer there is less than one ampere between 100 % of air flow rate (optimum) and less than 20 % of air flow rate (economically non-viable)! This corresponds to a tiny section of the ammeter scale, wherein the decisive measured values can basically neither be properly read nor can conclusions be drawn from them!
Even devices, whose ammeter has numeric values above the colour scale, can't help the impracticality of these measuring devices for the construction optimization of your installation!
And as if to cap it all off: Because some suppliers seem to be perfectly aware of the impracticality of ammeters for drying applications, some devices are additionally treated to a temperature display as overheating indicator – apparently for there to be at least one measured value one can work with to some extent. Which is then advertised as an additional "equipment feature"!
Ammeter and insulation dryer –
- The scales of values of commonly integrated ammeters are completely useless for drying technicians – even though the scale ranges often reach from 0 to 20 ampere, only a tiny millimetre range is relevant – the same goes for colour scales.
- Ammeters at most provide a rough indication of a possible turbine overheating.
- Between 90 % and 20 % of an insulation dryer's volumetric flow there is usually less than one ampere difference – in everyday working conditions it is impossible to precisely read and head for those values.
- Ammeters are absolutely unfit for system control and performance optimization of insulation drying installations.
Optiflow – modern-day optimization
Instead of ammeter and temperature indicator, modern professional Trotec insulation dryers with the unique Optiflow technology have as standard been equipped with a complex electronic solution ever since 2007; it intelligently collects, calculates and visualises important information concerning engine temperature, pressure conditions and volumetric flow.
Optiflow is by no means just a "replacement ammeter flashing in different colours" or a simple eye-catching gimmick – quite on the contrary: What looks simply on the surface, actually required intense background development work, lots of experience and comprehensive know-how to make the complex technology easy to handle for the user at first sight.
On our own behalf:
We have to admit, that the first Trotec insulation dryers were also produced with ammeters for system control. At the time it was the state of the art, however, this has long changed since 2007!
Why Trotec still integrates ammeters in the current VE 4 S MultiQube?
This is due to the fact that ammeters in competition models are still advertised as contemporary technology. We don't like to lecture – therefore: If our customers really want a compressor with ammeter, then with the VE 4 S MultiQube they can at least get the best price/performance solution on the market!
Focussing on the essentials
In simplified terms, the Optiflow electronics can i.a. distinctly increase the resolution of the relevant ampere range, which enables the signal processing of even the smallest of changes in value.
Metaphorically speaking, Optiflow acts as extreme magnifier, which can visualize even the slightest of changes in current values and thus allows a proper fine adjustment of the installation configuration.
Meanwhile, the representation of Optiflow is realized according to the proven traffic light principle from green to red via nine individual LEDs. This signal immediately provides a literally lucid explanation for every user, requires no complicated reading or converting of measured values and is always perfectly legible also from afar and in poorly lit surroundings!
"Lucid technology", which comes straight to the (LED) point
The more "green" there is in the Optiflow display, the higher is the drying installation's optimum performance. Green indicates an unimpeded air flow (> 90 %) through the insulating layer ground.
Yellow indicates, that the current installation is not quite right, but can be further optimized via additional relief openings. If the LEDs light up in red, then the air passage is not ideal (< 30 %!) and the construction needs to be changed radically.
Your Optiflow benefits:
- Construction of your drying installation
- Always at the highest efficiency level
- Comprehensible, immediately "lucid" self-explanatory traffic light principle
- System control display clearly legible
- Even from afar or in the dark
- Shorter drying periods due to maximum performance optimization
