The steps for a project in Dorset
Calculate
Fresh-air needs are calculated per room.

A unit is chosen for air flow, efficiency and space.
Install
Unit, ductwork, terminals and controls are fitted. In Dorset we agree timings around your opening hours.
Balance
Supply and extract air flows are balanced and commissioned.
Local points to consider
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
Leased premises
If your Dorset premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Summer bypass
A bypass avoids warming incoming air in summer.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
