’s Ventilation Unit MV-01 can be used in combination with several kinds of pyranometer models
(MS-80/80A/80M, MS-60/60A/60M and MS-40/40A/40M), pyrgeometer model (MS-20). The MV-01 will reduce the
need for maintenance and assures the availability of solar irradiance data when deployed in cold climate regions or
desert environments. Due to the compact and integrated design with pyranometer, pyrgeometer and UV
radiometer, the heating and airflow dynamics are optimized. The power consumption of the ventilator is only 1.9
Watts, which makes it suitable for solar powered systems. When the heater is activated the total power
consumption will be about 8.4 watt, which is sufficient to prevent snow and ice deposition on the sensor (dome and
sun screen).
Pyranometer with ventilator can be mounted in horizontal or tilted plane, which make it suitable for PV monitoring
applications. The Tacho output provides a data pulse to monitor the fan speed.
For the pyranometers, pyrgeometers or UV radiometer operated in harsh environments, the measurements can be
easily affected by environmental factors. In such case the MV-01 will keep the pyranometer dome free of dew, ice
and snow. In combination with the MV-01 ventilator the best possible measures are taken for reliable unattended
operation.

⚫
Low power consumption (power consumption: 8.4W, fan 1.9W, heater: 6.5W)
⚫
Wide range of operating temperature (-40
℃
to +70
℃
), the MV-01 can be operated in many different
areas of the world.
⚫
Overheating protection trough temperature fuse
⚫
Using the ventilation with long expected life has made possible to offer 2-year warranty.
⚫
By measuring the rotation signal (pulse signal) of the MV-01, the rotation frequency of the fan can be
monitored.
