HVAC Shielding Systems
HVAC (heating, ventilation, and air conditioning) Shielding, often referred to as Duct Shielding, is required where HVAC and other penetrations pass through a wall, ceiling or floor into a radiation therapy room or vault. HVAC shielding requirements are site-specific and are dictated by the physicist.
The most common shielding materials are any combination of N- Series Interlocking Lead Brick, lead sheet, lead plate, steel and five per cent borated polyethylene.
NELCO custom designs and builds HVAC shielding for every modality in radiation therapy. We can design, fabricate, and install any HVAC shielding concurrent with installation of a door system, saving time and money. If required, NELCO can provide consulting services for both physics and structural design.
Uses
- Linear accelerator vaults
- H.D.R. rooms
- Proton therapy
- Rradiosurgery
- Industrial applications
Dimensions
Dimensions of HVAC Shielding are unique to each room, and areas to be shielded are specified by the physics report.
FAQs
Q: What are the typical structural components of NELCO HVAC shielding systems?
A: Each is site specific. Generally, steel tubes, angles, flat bar, and plate.
Q: Are there any load issues to contend with?
A: Weight of the shielding needs to be independently supported. NELCO can supply any structural engineering associated with HVAC shielding
Q: When is HVAC shielding required?
A: This is determined by the physicist for the project. NELCO offers physics services when required.
Q: Does a NELCO HVAC shielding design need to be stamped by a structural engineer?
A: This may be required by location, and if is NELCO can offer structural engineering services.
