Technalogix Ltd. TAVD-500 Transmitter
VIII-2
Heating and Cooling Requirements
The environment’s temperature will contribute greatly to the length of the power amplifier’s life.
Technalogix recommends that the building’s filtered air intake must have capacity for all air-flow in
the building plus an additional 20%. Keep the intake below the roofline to avoid intake of solar
heated air. Please ensure that the intake and exhaust areas are on the same side of the building to
avoid pressure differentials during windy conditions. Also, do not position intake near exhaust’s
preheated air. If air conditioning is required to cool the shelter, discuss the situation with a qualified
HVAC technician. Under average conditions, 12,000 BTUs will cool approximately 500 square feet
to a comfortable level.
The TAVD-5000 contains (3) DC ball bearing fans in each PA (push-pull configuration) and (2)
fans in each of the combiner/filter and power supply enclosure.
