  • Dampers

    • Krantz Dampers

      • 2.1.1. Circular Damper Type GD-C

        Features:

        • The actual leakage rates for housings and seat of damper blade are much lower than specified in the requirement according to DIN 25 496.
        • The damper is designed to operate without any failure at an operating pressure of 1.1- times of the admissible operating pressure of the damper.
        • The tightness of seat of damper blade is testable in built-in situation.
        • For maintenance purposes, e. g. lubricating, if required, there is no dismantling of the damper from the duct system necessary.
        • All media touched parts are welded continuously and without gaps to ensure an easy decontamination.
      • 2.1.2. Rectangular Damper Type GD-R

        Information:

        The gastight rectangular shut-off damper, type GD-R, surpasses by far the leak tightness requirements specified in DIN 25 496 (Ventilating components in nuclear facilities).

        Krantz‘s gastight rectangular shut-off damper, type GD-R, guarantees a maximum of safety and reliability thanks to

        • its design,
        • its system and
        • the special damper mechanism.

        Features:

        • The specially designed kinematical mechanism secures the damper blade at the end positions “open” and “close” by means of special toggle levers in case of a failure of energy support.
        • Two concentric sealing rings fixed to the damper seat create high tightness as well as a test groove in the gap between the two sealing rings. In order to test the leak free seat of the damper blade the test groove can be connected to an appropriate seal test device via a fast acting coupling from outside the damper.
        • To protect the sealing the damper blade starts the opening process with a linear movement. This movement is created by a special lever system, so first the damper runs parallel and after reaching a certain distance the movement turns automatically into a rotating motion. This mechanism avoids transverse loading force to the
          damper sealing.
        • Double shaft transition sealing. Connections to test tightness of shaft transition during operation available on demand.
        • Housing, damper blade and lever mechanism made of stainless steel.
        • All media-touched parts are welded continuously and without gaps to ensure an easy decontamination.
        • The housing, the damper seat and the shaft transition surpass by far the leak tightness requirements of
          DIN 25 496.
        • Electrical, pneumatic and manual actuators available. The electrical actuator is also available as spring return (fail-safe) version.
      • 2.1.3. Rectangular Damper Type S

        Information:

        The requirements on tightness as laid down in the German standard
        DIN 25 496 – Ventilating components in nuclear facilities - are more than satisfied.

        Several decades of experience gathered in the operation of shut-off damper systems in nuclear facilities and labs have decisively influenced the design and shape.

        Quite a number of references from various locations of shut-off damper installation have proved the high level of perfection attained by this.

        Features:

        • The shut-off damper consists of a damper housing, a hinged damper blade with the damper shaft as its bearings, and an actuating cylinder moving the damper blade by an actuating equipment.
        • A sealing profile made of silicone rubber is fastened to the damper blade by a leading bar. Upon closure of the damper, this sealing profile is pressed against the damper housing by means of an inflatable silicon tube which produces the sealing effect.
        • The sealing profile provided with two double lips allows the tight seat of the damper blade on the mounted shut-off damper to be checked.
        • The damper blade and the damper housing are made of stainless steel, the tube leading bars and profiles consists of aluminum. The control unit is placed on the head of the actuating cylinder. The shut-off damper is actuated from a customer provided switchboard cabinet.
        • The media supplies needed by the control unit are electric energy as well as compressed air, 3 bar overpressure, oil free and waterless.
        • The shut-off damper is actuated by means of a double acting pneumatic cylinder. The control unit ensures the proper sequence of motions including tube inflation and venting, respectively. 
      • 2.2.1. to 2.2.4. Pressure Relief Damper Type KL

        Information:

        Krantz range of pressure relief dampers covers:

        • Pressure relief damper for high opening pressures, with control function, type KL-E
        • Pressure relief damper for high opening pressures, with switching function, type KL-EM
        • Pressure relief damper for low opening pressures at high volume flow, type KL-ETE
        • Pressure relief damper for low opening pressures at low volume flow, type KL-ETM

        Features:

        Pressure relief damper, type KL-E with control function

        The Pressure Relief Damper Type KL-E is a design variant provided with control function which, as soon as then opening pressure is exceeded, keeps nearly constant the pressure in the ductwork, independent of the range of volume flow. When the pressure in the ductwork reduces to its normal range after the malfunction has been remedied, the damper closes automatically.

        Pressure relief damper, type KL-EM with switching function

        The Pressure Relief Damper Type KL-EM features a switching function. Independent of the range of volume flow of the outlet flow the damper blade gets fully opened when the opening pressure is exceeded. When the pressure in the ductwork falls below the opening pressure after the malfunction has been remedied, the damper normally remains open. In this state of operation the damper type KL-EM must be closed manually, whereas it closes automatically when the flow is interrupted, e. g. by disabling of the fan. Despite its smaller outside dimensions type
        KL-EM is capable of removing flows at higher range of volume flow as compared with type KL-E.

        Pressure relief damper, type KL-ETE (at high volume flow) and KL-ETM
        (at low volume flow)

        It is often required that a defined pressure gradient of 50 − 150 Pa is set between two neighboring rooms. This guarantees a directed flow of air in the leakage ports existing between the rooms and thus avoids the undesired transport of pollutants into the room to be protected. Pressure relief dampers type KL-ETE can be used in this application both as control device for setting a defined pressure gradient between two rooms and as safety valve to set a limit to a maximum admissible pressure value. Depending on available space and range of volume flow to be relieved pressure relief damper type KL-ETE or type KL-ETM is the optimal choice.
