High Traffic Sliding R.F. Shielded Door

The Raymond EMC QuietDoor-HTs R.F. Shielded Door

The extremely low maintenance requirements of the QuietDoor-HTs make it the perfect hinged radio frequency shielded door solution for high-traffic EMI/RFI systems where physical space does not allow for a hinged door. The compression-type seal offers exceptional shielding effectiveness while eliminating the constant wear and oxidation seen with conventional RCM shielded doors. 

Key Features

Sliding Operation

Unlike conventional hinged doors, the QuietDoor-HTs uses a sliding leaf system making it the perfect high performance R.F. Shielded Door for applications where a swinging door is not suitable. 

Compression Type R.F. Seal

The exceptional R.F. Shielding Effectiveness of the QuietDoor-HTs is achieved through a compression action between two specially-treated surfaces spanning the perimeter of both the door leaf and door frame. Compression is created using a dual bladder system housed in the door leaf that, once the QuietDoor-HTs is fully latched, applies even pressure against a seamless door skin creating a perfect seal with the door frame. The QuietDoor-HTs does not use traditional fingerstock or gasket.

Redundant Bladder System

A common problem seen with other bladder door systems on the market is the rupturing of the bladder due to high pressure requirements and weak bladders. On top of using specially reinforced bladders rated to 300 psi, the QuietDoor-HTs employs a redundant bladder system that allows the door to operate at low pressure while still providing high R.F. Shielding Effectiveness.

High R.F. Shielding Effectiveness

QuietDoor Shielding Effectiveness Levels
Magnetic Fields: 20dB at 1kHz rising to 65dB at 10kHz and 105dB at 200kHz
Electric Fields: 120dB from 200kHz to 50MHz
Plane Waves: 120dB from 50MHz to 1GHz
Microwaves: 120dB at 10GHz
(Shielding Effectiveness Testing Standard: ITSG-02, IEEE Std 299-1997, NSA-65-6)

High traffic applications (>200,000 cycles/year)

The minimal wear of the compression type R.F. seal makes the QuietDoor-HTs the perfect hinged R.F. Shielded Door for high traffic Shielding systems.

Virtually Maintenance Free

Asides from ensuring the system is receiving the appropriate amount of air pressure, the QuietDoor-HTs requires no maintenance to maintain its R.F. Shielding Effectiveness performance.

Standard and custom sizes

The standard QuietDoor-HTs comes with a clear opening of 915mm (36”) x 2135mm (84”).

Custom clear openings are available.

Programmable Logic Control

Control of the QuietDoor-HTs is done using a programmable logic controller (PLC). The PLC allows each QuietDoor-HTs to be fine tuned to the specifications of each client and can be easily tied into facility security and emergency systems.

Heavy Duty Construction

The QuietDoor-HTs was designed with strength and durability in mind. The frame consists of a fully welded tubular steel frame mated with an R.F. Shielded Panel frame and a specially designed U-channel system for easy integration into a Modular R.F. Shielded Enclosure System using our standard clamp-style framing system. The door leaf consists of a tubular steel frame supporting a steel channel housing our redundant bladder system and supporting the seamless door leaf skin. An LM guide, rated at 3,000,000 cycles guides the door leaf smoothly during operation. System controls are located within the closet housing the door leaf


The QuietDoor-HTs comes standard with a pneumatically-controlled user interface allowing the user to operate the door with the push of a button. From the closed position, the press of the operation button causes the bladder to instantly deflate and the door leaf to retract, exposing the clear opening of the door. Once the user has crossed the threshold, the door will automatically slide closed and re-inflate the bladder system to regain the R.F. Shielding Effectiveness of the door.

Standard Safety Sensor

Each QuietDoor-HTs come complete with a dual bumper safety switch that runs vertically along the leading edge of the sliding door leaf. Contact with this safety switch will halt the closing motion of the door leaf to protect personnel and equipment.

As an additional standard safety feature, pressing the Operation button during the close cycle of the door will also halt the closing cycle of the door leaf.

Emergency Egress

The control system of the QuietDoor-HTs is designed to automatically deflate the bladder system in the event of air pressure or power loss. A standard recessed handle allows the user to manually slide the door open and egress. The system automatically returns to full-automation mode with the return of air pressure and power.

The control system can be overridden in the event of an emergency by pressing the Emergency Egress button, standard on all QuietDoor-HTs R.F. Shielded Doors. Pressing the Emergency Egress button cuts the compressed air supply to the system causing the bladder system to deflate and allowing the door to be manually pulled open.
The control system is easily set back into full-automation mode by pressing the Operation button to allow compressed air back into the system.

Secure Access

For secure facilities, a keypad, card swipe or any other electronically controlled access system can be integrated into the control system of the QuietDoor-HTs to limit the operation of the door to specific users.

Two-year Limited Warranty

Our standard warranty covers parts and labour for two years. Extended warranties and preventative maintenance agreements are available.
