We would need the number of hoods, hood configuration (i.e.
wall, island, etc), number and size of exhaust collars on
each hood, and fan information (HP, voltage, and approximate
distance from hoods).
3) Can I install these controls on an existing location?
Yes, we can install the controls as either new construction
or retrofit.
4) If installing as a retrofit, how long does it take?
A general rule of thumb is that two hoods can be retrofitted
in one night by two people.
5)
How many hoods will the Intelli-Hood control?
Each Intelli-Hood I/O Processor can control up to four fans.
6) Will the Intelli-Hood work with single-phase motors?
No, the fan must be three-phase.
6b) What if I don't have three-phase power on site?
We can take a 115V or 230V single-phase input through our
variable frequency drives (VFDs) and convert it to 208V
three-phase. These are
special drives, and we are limited to 1-1/2 HP on the 115V
input.
7) Can the Intelli-Hood be integrated with a Building Management System?
Yes, we can provide a 0-10V signal from each fan and the
average of all the fans.
8) Does the Intelli-Hood control the MUA unit as well?
Yes, we will modulate the MUA unit as an average of the
exhaust fans.
9) How do you go to
market?
We sell the controls through the major hood manufacturers
for new construction, and for retrofit applications we
generally sell them direct or through reps.
10) What keeps the optic sensors within the hood from
getting dirty?
Each Optic Sensor enclosure has a purge fan that keeps the
environment inside the enclosure under a positive air
pressure. This prevents contaminated air from entering the
sensor unit.
11) Must I have direct drive fans installed to be compatible
with the controls?
No. However, if the fans need to be replaced in a retrofit
application, it is a good idea to consider replacing
belt-drive fans with direct drive equivalents.
