The design stage to your requirements can be split into many categories.
1. Internal requirements to give the required environmental control for the degree of comfort required
2. Services required to supply the internal requirements.
3. External equipment required to give the required environmental system and control.
4. Additional requirements to be added to the system.
Some of the systems may require different temperature control, different general environmental control in as much as a clean room atmosphere. Comfort for Offices, Clean rooms, factory ventilation, shop heating etc. All can be encompassed within the package.
Finally there may be requirements to have dedicated cooling devices for machinery. This may have to be within a separate unit.
Another item for the consideration would be Heat Recovery systems. These too can be included within the package.
Consultations can be arranged for the required site visits.
