There are different types of dampers:• Fire and gas dampers• Shut-off dampers• Balancing dampers• Non-return dampers / Pressure relief dampers• Blast dampers• Air-flow adjustment dampers

Fire and gas dampers Fire and gas dampers prevent the spread of fire, smoke and gas between fire zones, where people must have the maximum amount of time to react to possible fire. The dampers are type-approved according to A0 (A60) or H0 (H120).The patented blade structure of the FDB2 dampers have special seals that are effective up to 300 °C and thermally activated graphite seals that expand when the heat rises to 150 °C in ductwork. These unique safety features ensure air tightness and low leakage to prevent fire, gas and smoke progression in a ductwork.

shut-off dampersShut-off dampers shut off the airflow in ductwork where tightness, thermal insulation and reliability are important. The dampers meet international standards for rectangular and circular ducts. The leakage class is accordance with the EM1751 standards.

UTT shut-off dampers

Frame: AISI 316 or galvanized steel.Thickness: 1 mm.Blades: AISI 316 or galvanized steel. Blades are insulated and have seals.sizes: 100x100 ~ 2400x2400 mm at 50-mm intervals (special sizes available).Circular connection pieces: 100 ~ 1250 mm.Operation system: by static air pressure.

Balancing dampers Balancing dampers adjust or control the air flow rates in ductwork where leakage does not have significant importance.

UTK balancing dampers

Frame: AISI 316 or galvanized steel. Thickness: 1 mm.Blades: AISI 316 or galvanized steel. Blades have seals (tightness class 1).size: 100x100 ~ 2400x2400 mm at 50-mm intervals (special sizes available).Circular connection pieces: 100 ~ 1250 mm.Operation system: by static air pressure. Maximum pressure across the dampers: 4000 Pa. Maximum air velocity: 16 m/s.

Non-return dampers / pressure relief dampers Non-return dampers and pressure relief dampers are used in oil and gas applications to prevent backflow and relieve the pressure through ventilation ductwork. The opening pressure can be individually adjusted. The dampers are also applicable in marine ventilation systems.

BLd non-return dampers / Brd pressure relief dampers

Frame: AISI 316 or painted or galvanized steel.Thickness: 3 mm.Blades: AISI 316 or galvanized steel.

Modules possible.

Blast dampers Blast dampers protect ventilation systems against the effects of explosions. The dampers shield industrial facilities and related buildings against destructive blast forces. The dampers offer higher air flow capacity and increased level of safety as well as flexibility for design of duct systems.

HV blast dampers

material: AISI 316 or galvanized steel.Blast protection: up to 1 bar (14,5 psi).standard sizes: 300x300 ~ 1500x1500 mm.Note: Modular construction available for high airflows and large ducts. Maintenance-free design. Minimum leakage on pass-through pressure and impulse. Minimum turbulence and pressure drop.

air flow adjustment dampersPRA air flow adjustment dampers are manually adjustable measurement units for circular ducts. The dampers are used in duct systems to control the air flow.

pra air flow adjustment dampers

Casing and blades: Galvanized steel.Circular construction: 100 to 315 and 350 to 1000 mm. Adjustable cone and air flow measurement taps for differential pressure adjustment.Classification of casing leakage: EN1751 Class C.

Control The dampers can be controlled electrically, pneumatically or manually. In case of fire, the fire and gas dampers will close automatically.

The electrically and pneumatically controlled dampers are driven by an actuator.

Belimo actuators: As standard actuator. schischeck actuators: Actuator used in explosion-proof areas or if the actuator must open/close within 3s/900.

Certified quality In addition to ISO 9001, ISO 14001, quality and environmental management certificates, marine fire dampers conform to leading classification societies worldwide. Several dampers are ATEX-certified and shock-tested products for naval applications, ships and submarines.

FeX fire and gas dampersFEX fire and gas dampers are used in offshore, nuclear and navy ventilation systems. The dampers are type-approved according to H0 (H120). The dampers protect the integrity of bulkheads where they are penetrated by ventilation ducts. The dampers can be installed in rectangular or circular ducts. The dampers have a fusible link and prevent the spread of fire and gases (low-leakage model) within the ventilation ductwork. When the blades are in the open position, the device does not cause significant pressure loss, noise or flow disturbance. The dampers are set from outside and can be installed in bulkheads. An open-closed indicator is visible on the outside of the dampers.

BLd non-return dampersBLD non-return dampers are used in offshore and marine applications to prevent backflow through ventilation ductwork. The dampers do not require an actuator or motor. The dampers can be installed in rectangular or circular ducts, horizontally or vertically. If required, the dampers can easily be set by adjusting the weight of each damper/installation. Weights for the dampers are available as an option. When the blades are in the open position, the device does not cause significant pressure loss, noise or flow disturbance (with weights). Non-standard dimensions are available on request.

• Fixed frame in painted, galvanized or stainless steel. Blades of galvanized or stainless steel.• Models for horizontal or vertical installation.• Closed damper meets the leakage requirement of NORSOK. Leakage class of closed damper according to EN 1751 class 2 (VTT test report no. RTE4306/04).• Blades have silicone seal to lower the leakage through blades.• Blades linked and open in parallel.• Adjustable by changing the position of counterweights. Counterweights available on request.• Standard construction places weights on the right-hand side. Weights on the left-hand side available as an option.• Maximum duct pressure: 5000 Pa. Maximum air velocity: 15 m/s.• ATEX approved.

dimensions and material thickness The dampers meet international standards for rectangular (width B 200-1200 and height H200-1400 mm, 1 mm division) and circular ducts (Ø 100- 1250 mm). Non-standard dimensions are available on request. Modular construction sizes up to 2400x2800 mm are available. Standard frame material thickness: 3 mm. Standard flange width: 27 mm.

HV blast dampersHV blast dampers protect ventilation systems against the effects of vapor and dust cloud explosions. The dampers shield industrial facilities and related buildings against destructive blast forces. The dampers offer higher air flow capacity and increased level of safety as well as flexibility for design of duct systems. The structure of the dampers is corrosion-free, hot-dip galvanized steel (AISI316 in the HV-SS version). The dampers have spring-loaded closing blades in a fully welded damper body to close the air passage in case of explosion or sudden increase of overpressure in the HVAC system. The threshold trigger pressure can be adjusted according customer specification. When the blades are closed, they will remain in closed position until they are manually reset. The dampers are approved according ATEX (Ex II 2 G D) for equipment in hazardous environment.

• Made of galvanized or stainless steel, AISI316.• Fully welded damper body made of 5-mm steel.• Closing blades and shafts with stainless-steel bearings.• Adjustable trigger mechanism.• Fragment grill.• Flow guides.

General drawing The dampers are dimensioned according to the duct size or wall opening.

Standard sizes:• 300x300 mm• 500x500 mm• 700x700 mm• 1000x1000 mm• 1500x1500 mm

The dampers are also available in custom sizes with steps of 100 mm in each direction between the limits.
