Programmable cooling fans made to order

July 2000 Analytical Instrumentation & Environmental Monitoring

This new fan concept by Papst is 'software instead of hardware'. This means that the configuration is set purely on a software basis, allowing shorter lead times and sampling ex stock.

The ability to deliver customer-specific individual solutions in large-volume production or in small quantities are the main advantages for the customer. Customers select the profile for their fans and PAPST fulfils these requirements in the shortest possible time. The customer receives expert individual advice on hardware selection and profile options. The intelligence in the fan includes the ability to output data and the ability to quickly program operating parameters. This is done by downloading them as software modules via a data line into the 'brain' of the fan. Motor control functions normally performed by analog components are instead performed by the easily adjusted software.

Advantages for the customer include:

* Freedom of drift and service life stability due to digital control.

* Economical option in both large-volume and small quantities.

* Digital control offers higher reliability than analog.

* Free choice of any speed profile within the permissible speed range.

* Automatic triggering of emergency measures or automatic switch-off/warning signal when critical temperatures are reached.

Technical features for VarioPro are:

* Temperature as speed controlled variable.

* Speed profile for defining as required in the temperature range of -40 to +100°C.

* Temperature sensor integrated or external - for required positioning.

* 0 rpm speed is possible.

* Recognition of torn off sensor: In case of sensor failure, the fan runs at maximum speed (programmable).

* Interface for external speed setting.

* Required curve also with external set value by PWM signal or control voltage speed profile.

* Description of speed curve by up to 14 interpolation points, with linear interpolation between the points.

There are numerous alarm options, from speed limit (with hysteresis), saving of alarm signal, delay alarm on start-up, or permanently, active high or low for alarm output, alarm for loss of temperature sensor, excess temperature alarm. Motor management options allow the accurate calibration of fan speed - and yield more efficient and reliable performance, due to the ability to optimise the control software for each fan. This works to extend the operational life expectancies of the fans.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
