Commissioning and servicing

Our highly experienced commissioning and servicing team have all the necessary site clearance and qualifications to commission and/or service the installed Passivent equipment (see separate section for more information about our network of installers).

The Project Administrator would organise a suitable date with the customer for commissioning, often well in advance. The commissioning time may vary from one day to multiple days depending on the size of the project. The price for the commissioning service is based on a day rate and whether any overnight stays are required.

At the commissioning stage the engineer will carry out a full and comprehensive demonstration of the Passivent controls and equipment, and also associated equipment, to the client and end users.

If a service visit is required then a daily rate is charged. Any replacement parts required may carry an additional cost depending on warranty status of the equipment.
