What does a sound installation show?
Frame and supports
The unit should sit on a level steel frame or concrete plinth so vibration does not reach the structure.
Airflow and service space
Keep space around the unit for airflow and for service doors to open.
Valves and insulation
Isolation valves, strainers and gauges on the water loop, with fully insulated pipes.
Power and controls
A local disconnect, earthing and a control panel coordinated with the designer.
State the capacity, building type and city and a suitable system can be proposed.
Frequently Asked Questions
Are all these images NAD projects?
These images are examples of rooftop HVAC installations shown to illustrate the method of execution. For specific project references, ask us through the quote form or by contacting us.
What must be checked before installing a chiller on a roof?
The structure load limit against the operating weight, air clearance around the unit, space for the pump and expansion vessel, pipe route and insulation, and available power. The full checklist is in the rooftop chiller installation article.
Which spaces suit a rooftop package unit?
Large open spaces without an indoor plant room, such as cinemas, sports halls, stores and workshops. Capacity runs from about 3 to 30 tons of refrigeration.
