Most of our linac vault doors typically feature minimalist lines and unique materials, giving you a fresh perspective on your floor plan. The design and manufacturing is a two-way process between supplier and client. When it works, the final product should prove to be the perfect fit for the project. The other aspect of the design is the focus on detail. The parts of our products such as door handles, wood finishes, and steel lines can be selected in an amazing number of choices.

Linac Door General Specifications:

• 1.Structural steel support of type ASTM A 36/A36M for beams and ASTM A500 for rectangular tubing or equivalent. The maximum allowable deflection of overhead support beam under full loading: 0.015 inch over length of beam.
• 2.Lead brick: Approx. ……… cm * lead block conforming to ASTM B-29, defect free. Uniform thickness (maximum variation 3%) pure virgin lead, free from dross, oxide inclusions, scale, laminations, blisters, and cracks as required by IAEA.
• 3. Borated polyethylene: Approx. of ………. cm* thickness, high-density polyethylene consisting of minimum of 5 percent boric oxide as required by IAEA. Rigid Polyethylene Sheet: HDPE (Rigid High-Density Polyethylene) as required by IAEA. * calculated based on room design]
• 4.Door finish: washable, laminate finish linac door swing or sliding with color in harmony with the building (post selectable).
• 5.Concrete (if need arise) as required by IAEA
• Should function as a manual door in the event of any power loss.

General:

A-Linear Motion System:

Block type linear motion system, upper side mounted rail system with a single slide unit (block). B-Lubrication: Pre-packed, high quality, lithium soap-based grease containing extreme pressure additives.

C-Door Operators:

Electric, automatic door operator, with power opening and power closing features including two press wall switches. Two or four kill switches as necessary for use with power cutoff when radiation machines are in use shall also be provided.

• Motor: self-contained, surface mounted electro mechanical.
• Supply Voltage: 220 Volt AC, 50/60 Hertz, single phase. Provide in-line
• breakers, surge protection, line filters and EMİ ferrites.
• Control Unit: Enclosure Type and Rating: NEMA 1 vented enclosure / control box.
• 1. Travel as it needed (approx. 60 inches [150cm* optional]).
• 2. Rated Linear Speed (Maximum): approx. 4.5 inches per second [11.43 cm/sec].
• 3. Minimum Rated Cycles (openings and closings): approx. 500,000.U

Sequence of Operations 

OPEN: should be able to override both the partial open and close buttons. When the open button is pushed, there should be a one-second delay before the door begins to open.

CLOSE: should not override any other buttons. The door must be stoppable before it close.

STOP: should stop the door from any current position along its path of travel.

PARTIAL OPEN / PARTİAL CLOSE: should make the door travel to the preset partial open position and stop. This button should be able to over-ride close and should have a one second delay before opening.

Linac Radiation Door Safety Items:

A) Electric Sensing Edges: Door should have reversing edges or photocell reversing strips. Should be activated at approx. 4 pounds (18N) of pressure is applied to the reversing edge

B) Safety beam: between the photocell’s is broken, an electronic signal shall be sent to the door operator and cause the door to stop and then open.

C) Presence Detection System: Active infrared presence sensor providing two infrared curtains (one on each side of door) that shall detect stationary humans or objects within the sensing Pattern General characteristics:

• 1.Infrared curtains, comprised of 2 rows of 24 focused infrared spots, shall have angle
• adjustment capability, and shall be capable of reaching within 2 inches (51 mm) of the
• face of the sliding door.
• 2.Sensor shall have a narrow or wide sensing pattern as determined by a user-selectable
• lens. Pattern size adjustments made by field masking a lens shall not be acceptable.
• 3.Sensor shall provide a 6 feet 6 inches (1.98 m) wide (wide lens) pattern when mounted
• at 7.5 feet (2.3 m), and a 3 feet 3 inches (1 m) wide pattern when using the narrow lens
• Sensor shall have a minimum self-adaptation time of 30 seconds that enables the sensor
• to learn permanently changed environments.

D) Emergency Power Supply: door should have battery backup at least two 12 VDC, 7.0 Ah battery with float chargers. İn an emergency the OPEN button shall operate in a “dead man” mode.*Optionall.
