Tor kan injustera ventilation tre gånger så snabbt

Ventilation technician Tor Halvorsen uses Celsicom V600 reference sound level meters for ventilation adjustment.

With over 20 years of experience in the industry, ventilation technician Tor Halvorsen knows the importance of reliable measuring equipment for effective adjustments. He has been using the Celsicom V600 for just over a year. The results have been unequivocal: less time and more precise airflows, smoother operation and significant energy savings.

Tor Halvorsen and his colleague Patrik Pålsson at VXPro AB specialize in ventilation adjustments in all types of properties. Everything from homes belonging to small and large housing associations to commercial premises and offices in properties of all sizes.
– When we work for housing associations, it can be from twenty to several hundred apartments with three to seven measuring points per apartment. For example, in a residential area with 300 apartments, there may be an average of around 1,500 air diffusers. In addition, there are public spaces such as laundry rooms and community halls. So it’s important to work smart with ventilation adjustment,” says Tor Halvorsen.

Traditional adjustment – time consuming and outdated values
Traditional adjustment means that the reference sensor is measured repeatedly during the adjustment of the other sensors. This is necessary to see the current ratio (the ratio between the current value and the target value) to adjust against. The ventilation technician then has to go back to the reference device often, usually three times – sometimes up to six or seven times, to check it. After a while, it becomes uneconomical to go back to the reference device after each throttling. If control measurements are not taken, the result is that the current quota is not always available.
The solution to avoid time-consuming control measurements and minimize adjustment errors is real-time reading of the current ratio. With traditional tuning, real-time reading can only be achieved by a technician continuously measuring the reference actuator and communicating the new ratio via radio or telephone to the colleague throttling the actuators.

Averaging is key
Many measurement solutions for real-time readings consist of reference densitometers connected via radio or Bluetooth (with limited range), a base station and a modem. The Celsicom V600 consists of a single unit: a compact, battery-powered reference densitometer.
After the meter automatically connects to the mobile network, the ventilation technician continues his work in the web-based Celsiview cloud service on a mobile or tablet. The screen displays the current values of the reference device and guides the technician through the adjustment of all devices.
– Thanks to the Celsicom V600 averaging, I can see immediately if the values are within the right range. I can easily see fluctuations in pressure and use the average instead. This means I can often get the difference down to two or three percent, which is more accurate than the normal method error of six percent,” says Tor.

“Small and flexible measurement solution“
Tor previously used Celsivent, the predecessor of the Celsicom V600. He was quickly impressed by the new model:
– The V600 is a small and handy measurement solution. Apart from the meter itself, all you need are batteries and measuring hoses, an optional air flow or pressure gauge, and your regular mobile phone or tablet. It starts up and connects quickly. After a few minutes, you are ready to start measuring.

Tor also appreciates a number of small but important details that make his job easier. These include the magnetic bracket and the measuring hook that allow Tor to easily and safely connect the V600 to supply air and exhaust air devices.
– I also like the fact that the battery status is clearly displayed on the tablet, so I don’t have any unpleasant surprises. The operating time is also really good. I can often measure for several days without having to change the batteries in the V600, which is powered by standard AA lithium batteries.

Emergency job cleared up quickly
Tor and his colleague Patrik recently got clear proof of the benefits of Celsicom V600 during a job on the island of Öckerö outside Gothenburg. At short notice, they responded urgently and made adjustments in two properties with a total of 18 apartments.
– We expected to spend eight hours, but finished in five. And that’s despite the fact that the installation wasn’t finished when we arrived. We even had to help the electricians with the control technology to get the fans going,” says Tor and adds:
– “It was good for us to once again get confirmation of how well the Celsicom meter works. The adjustment itself took about three to four hours, which is also three times faster than traditional ventilation adjustment!
No wonder that Celsicom V600 has become an obvious work tool for Halvorsen and Pålsson at VXPro AB.
– Everyone I have recommended it to is happy. It is an invaluable tool for anyone working with ventilation adjustments.
