Replaces OBSOLETE models A1014, A1014L, A1014L1, & A1014U Selectra® systems from Maxitrol maintain precise, stable gas-fired temperatures. Selectra\'s unique electronic Modulator or Modulator-Regulator valves control gas flow with instantaneous response and continual adjustment. They are the superior alternative to mod motors and butterfly valves. OEM or retrofit applications include environmental climate control, as well as industrial or commercial heating processes. Standard temperature adjustment range 55° to 90° F. All fuel gases are compatible - capacities to 30,000,000 Btu/h.
Selectra Series 14R electronic gas flame modulation systems are designed primarily for make-up air heating, as components of direct fired equipment. They may be field installed on existing equipment or specified for new equipment installation. The system uses Modulator or Modulator-Regulator valves, amplifiers which include low-fire start, and integral or remote temperature selection and a discharge air temperature sensor that is mounted within a mixing tube. Available standard companion electronics include temperature selectors, amplifiers, and temperature sensors, in a variety of configurations. The amplifier supplies output voltage to the M/MR valve.
