CVF4 Ventilation Unit – Kipp & Zonen

Ventilation of solar radiation instruments improves the reliability and accuracy of the measurement by reducing dome soiling by dust and dirt. With thermopile-based pyranometer and pyrgeometers ventilation stabilises the temperature of the radiometer and reduces thermal offsets. The integrated heater can be powered to prevent dew formation, disperse precipitation and melt frost, ice or snow on the dome. Using ventilation and heating maximises the up-time of good quality data and extends the cleaning interval.

CVF4 is a low power, low maintenance ventilation unit. The only part that needs maintenance is the air inlet filter, which should be checked at regular intervals and cleaned or replaced when necessary. No tools are required for this and the unit is supplied with 5 spare filters. There is a 5 V pulse signal so that the fan speed can be monitored.

The air flow that the CVF4 creates is unique; it swirls to improve the distribution over the top of the dome. This has now been further improved using an optimally shaped air duct and a new fan that has higher air flow and is waterproof. The interface electronics have also been redesigned. As a result, the improved CVF4 now comes with a 5-year warranty and it is protected to IP68.

CVF4 is designed to be used with Kipp & Zonen’s:

CMP / SMP pyranometers
CGR / SGR pyrgeometer
CUV5 / SUV5, SUV-A, SUV-B and SUV-E ultraviolet radiometers

CVF4 can be mounted on our SOLYS2 and SOLYS Gear Drive sun trackers and the CM121C shadow ring.

Note: The original model of CVF4 (up to serial number 193799) has a 5-year warranty.
