Electronic Modulation Gas-Fired Temperature Controls/ Direct Fired Applications
Selectra® systems from Maxitrol maintain precise, stable
gas-red temperatures. Selectra’s unique electronic Modulator or Modulator-Regulator valves control gas ow with instantaneous response and continual adjustment. They are
the superior alternative to mod motors and buttery valves.
OEM or retrot applications include environmental climate
control, as well as industrial or commercial heating processes. Standard temperature adjustment range 55º to 90º F. All
fuel gases are compatible - capacities to 30,000,000 Btu/h.
Available standard companion electronics include temperature selectors, ampliers, and temperature sensors, in a variety of congurations. The amplier supplies output voltage
to the M/MR valve.
MAKE UP AIR APPLICATIONS
Series 14 System
Selectra® Series 14 systems are designed primarily for
make-up air heating, as components of direct red equipment.
SPACE HEATING APPLICATIONS
Series 44 System
Selectra® Series 44 systems are designed primarily for
space heating, as components of direct red equipment.
A wall mounted Selectrastat® senses space temperature
and has an integral selector with either a 55º to 90º F or
40º to 80º F range. A discharge air temperature sensor
(and mixing tube) is a means of limiting the minimum and
maximum discharge air temperature.
Ampliers are available with low-re start duration feature.
Option:
Instead of a Selectrastat, a separate remote tempera-
•
ture sensor and selector can be substituted.
A discharge air temperature sensor is mounted within a mixing tube housing.
Ampliers are available with low-re start duration, and integral or remote temperature selection.
Options:
A room override thermostat provides space tempera-
•
ture control by raising the discharge air temperature to
a preselected point - when used in conjunction with the
remote temperature selector.
An inlet air sensor (and mixing tube) provides inverse
•
change in discharge air for each degree change in inlet air - when installed in a convenient duct location upstream of the burner.
A dual temperature selector replaces TD114 to provide
•
dual control for door heaters, or other applications such
as paint spray booths.
