Comprehensive technical support

Our support to architects, consultants and contractors ensures the project runs as smoothly as possible and achieves the best possible natural or hybrid ventilation strategy. Passivent’s experienced Technical, Sales and Commissioning teams are always on hand to add extra value to your project providing customers with a full range of support which includes early design guidance, bulk air flow calculations, thermal modelling (when required), value engineered solutions and commissioning or after-sales services. Other technical support includes structured quotes, site visits, CPDs and a wealth of technical information such as product literature, case studies, BIM objects, NBS specifications, specification clauses, specification documents and sample wiring diagrams.

Having undertaken a number of natural ventilation installations with Passivent equipment over the last few years. I have always found their technical support and assistance to be first class – this has ensured the smooth running of the projects. We look forward to doing more work with them in the future.

Darren Pearce, Director, James Liston Building Services Ltd

We initially contacted Passivent in 2018 enquiring about natural ventilation products for a project we had secured with Vinci Construction, Kings School Macclesfield. A&B took over the design from consultants Pick Everard and after a few discussions with Passivent we decided to bring them on board and assist us with designing the natural ventilation to spaces within the building and provide technical information for input into our thermal modelling. The technical guidance and process of placing the units into manufacture from Passivent was made very straight forward. In July 2019 we received our first delivery, the fitment of these Airscoop units and the wiring of the iC8000 intelligent controls was simple making the commissioning period a real success. Passivent is definitely a company I will be utilising in the future.

T G Escapes Ltd first engaged with Passivent in early 2019 and the company have since become a valued part of our supply chain, working closely with our design, procurement and operations teams. We have found the Passivent team to be knowledgeable, helpful and accommodating and have developed a strong relationship with our Passivent account manager, they have always been responsive to any queries raised. Strong lines of communication ensure our requirements are scheduled well in advance and products arrive on site in line with our programme of works. We look forward to further strengthening our relationship in the coming years and see Passivent as a valued part of our robust supply chain.
