Description of actuators for fire dampers

Electromechanical spring return actuators designed to control the damper, which are installed in ventilation and air conditioning systems.

The control signal for operation with an electromechanical servo drive is to remove voltage from the drive, resulting in return spring moves the air damper from the initial position to the working (protective) position. When voltage is applied to the drive, the electric motor moves the damper to its original position and holds it in this position, consuming little power.

Fire damper actuators equipped with:
• manual control mechanism, thanks to which it is possible to return the damper to
  initial position when the power supply is off;
• two built-in switches signaling the operating (protective) position of the damper (up to 5°) and the initial position of the damper (90°-95°);
• spring (spring return), with the help of which the position of the air damper changes;
• thermal disconnection device (models with temperature sensor -T) that operates at a given temperature (only for normally open valves).

Dastech electric fire damper actuators

Dastech servos with spring return are characterized by high quality of execution and reliability in work. For fire dampers I have a special line Dastech FR – spring return actuators for installation on fire-fighting normally open valves.

General characteristics of all models Dastech FR:
• Metal housing IP54;
• Transmitting link on the shaft 12x12mm;
• Possibility of manual control with a hexagon (included in delivery)
• Japanese Mabuchi electric motor
• Additional switches (SPDT)

The range consists of 24V or 230V models with torques of 3Nm, 5Nm, 10Nm and 15Nm. There are also models for 5 Nm with temperature sensor.

Fire actuators Nanotek fire dampers

Nanotek spring return servos are in great demand among the Russian consumer and are similar in their markings to Belimo electric drives.

Like Belimo, fire fighting Nanotek divided into two lines for small and medium valves. Nanotek BLF are installed on dampers up to 1m², and Nanotek BF can already be connected to the damper up to 1.5m².

It is worth noting that the Nanotek BLF 24/230 B 3 MB models are not complete analogues of the Belimo BLF, because torque 3Nm, against 6Nm for Belimo. The rest of the specifications are the same. So closer to Belimo BFN230 (4Nm motor and 3Nm spring) than BLF230 (6Nm/4Nm). And you should also pay attention to the Nanotek BLF 24/230 B MB models - these drives are 5 Nm.

Nanotec BF- these are 10Nm drives, while Belimo BF has 18Nm for the engine. Closer to BF will be Dastech FR models at 15Nm. All this must be taken into account when choosing similar to Belimo to make the right choice.

Electric actuators for fire dampers are used to regulate the air damper, which allows timely prevention of the possible occurrence of an emergency. So, in the event of a fire in both residential and industrial premises, the electric drive automatically sends a command to the air damper mechanism, closing it. Thus, a barrier is formed to fire, smoke and dangerous impurities that may be contained in the air.

Electric actuators for valves: specifics and purpose

Actuator for valve- a device that is actively used in industrial, industrial and residential communications. The ventilation electric drive is a high-tech device that allows you to ensure optimal performance of the ventilation system.

Drive selection principles

If you want to choose an electric drive yourself, you should consider several basic aspects of these devices.

1. Drive mount type. Attachment can be done in different ways. Most often there are 3 types of fastening - latches, nuts and glasses. So, when choosing a valve, it is necessary to take into account the type of connection to the electric drive.
2. Type of valve action. Valves also differ in their principle of operation. They are geared and thermoelectric. The work of gear drives is due to the gear transmission. This type of device allows you to transfer energy from the motor itself directly to the valve, which drives it. The thermoelectric type of drives works on an electric spiral. The spiral itself heats up and increases the pressure. As it rises, the valve stem begins its work.
3. Stock size. This operating parameter can vary from 5 to 50 mm. It is important to know that for correct operation it is necessary to select such a drive, the stroke value of which will exceed the rod value.
4. performance. This indicator seems unimportant, but it is worth paying attention to it. So, there are fast and slow electric drives. So, it is preferable to install the fast type of device on inertial systems (the average reaction speed is 3 seconds).
5. Voltage. It is especially worth considering the voltage level, which can vary from 24 to the usual 220 V.
6. Working effort. It is also worth considering and focusing on this parameter almost in the first place. So, it can vary from 50 to 5000 N.
7. Protection. An important parameter is the presence of additional devices. The most important of these are protective. Usually, a quality device is equipped with a spring that provides quick closing without electricity. Also, the device may additionally have an air damper. Its function is to protect the heater from low temperatures.

Considering these parameters when choosing an electric drive, you can get complete confidence in the correct operation of the device.

Fire dampers for ventilation systems are special devices that are designed to prevent combustion products from entering the ventilation system and cut it off from the source of ignition. These are made mainly from materials capable of withstanding exposure to significant temperatures for a long time.

Classification by design features

The main regulatory document that regulates the areas of their use in fire ventilation systems is SNiP 41-01-2003. According to this regulatory document, the following types of devices are produced:

Valves open normally. They are mounted on the exchange air ducts of conventional ventilation systems, in air exchange and air conditioning systems, as well as in air heating networks to prevent toxic combustion products from entering the system. And for supply and exhaust air ducts for rooms equipped with automatic fire extinguishing systems, with gas or powder filling. Such devices are triggered by closing to form a sealed space in the room, filled with fire extinguishing agent to increase the efficiency of fire extinguishing. They operate automatically at the command of the fire extinguishing system.

Operation of a normally open fire damper using the PSUM 90 MANDIK model as an example:

The normally closed damper is installed in specialized ventilation systems to remove smoke and spent fire-extinguishing gas from the premises. They are opened in manual mode or on command by fire dampers, after the complete elimination of the source of ignition.

Operation of a normally closed fire damper using the MANDIK PKTMIII 60 model as an example:

1. Double-acting devices are used in air ducts of a similar purpose, which are used both for ventilation of a building and for cleaning a building from fire combustion products. They can be controlled automatically from the fire extinguishing installation or have their own control device if the room is equipped with autonomous gas fire extinguishing modules.

2. Smoke dampers for smoke exhaust systems are smoke exhaust devices, which are shut-off and adjustable equipment.

   The devices are mounted at the intersection of pipelines of the smoke exhaust system and interfloor ceilings, walls and partitions. Typically, such devices are equipped with two types of controls:

   • The electromagnet is economical, which is in a normally closed standby state. When a fire is detected, an impulse is applied to the electromagnet, which removes the blockage. The lid will lift due to the mechanical force of the spring. In the reverse - the security state of the damper is returned manually.
   • The electric actuator is in a standby state of closing and is de-energized. When necessary, electrical power is supplied to the damper, which opens the electric motor. The device returns to its original position automatically on command from the fire extinguishing system or control cabinet.
3. Explosion-proof valves are of two types. Normally open and closed. Their use and installation in air ducts for various purposes is regulated by normative documents SNiP 41-01-2008 and SNiP 21-01-97. Such devices are equipped with industrial exhaust ventilation systems in hazardous and aggressive industries. Their strength and performance indicators are significantly superior to conventional devices. Operating temperature range is -30°С to +40°С.

For long-term operation of devices, it is necessary to adhere to the following rules in accordance with GOST 15150-69:

• Observe the temperature regime;
• Protect the main control units and the body of the device from the negative effects of atmospheric moisture and direct water ingress;
• Eliminate condensation or other type of moisture on the damper of the device;
• Do not use conventional (non-protected) devices in air supply or exhaust systems that have a dual purpose and are used to extract aggressive substances from the place of production. Or in the environment of aggressive gaseous substances, fumes of acids and alkalis, the limiting concentrations of which reduce the corrosiveness of the body.

bug 1

The fire damper KLOP 1 blocks the ingress of smoke and its spread through the ventilation ducts used in air heating and central air conditioning systems. It can be used both in public buildings or industrial buildings for various purposes, as well as for ventilation systems arranged in a private house.

A channel-type device with a control system equipped with two flanges and an electric power drive located outside the air channel is being produced. The fire resistance limit depends on the materials from which the body and damper of the device are made. The most popular models IE60 and IE90 are able to withstand 60 and 90 minutes of direct exposure to fire.

Various modifications of the KLOP 1 product can be equipped with:

• Automatic thermal blocker, triggered at 72°C;
• Power unit on coils activated by a temperature sensor at 72°C;
• Mechanical lock with a spring drive, activated by a thermal sensor 72°C or 141°C, equipped with a microswitch between modes.

KPU 1M

Fire damper KPU 1M - in standby mode, the device is energized in a normally open state. It is completed with a built-in return spring, pre-charged into working condition, and an activation electric drive (BELMO). When the device is de-energized, the spring works, setting the damper to the closed position.

The device is triggered in the following cases:

• When the power is turned off;
• Upon receipt of a command from an automatic fire extinguishing system or a separate valve control module;
• Upon reaching the threshold value of the critical temperature in the duct 72°C;
• In the extended configuration, it is possible to install an additional thermal relay to determine the temperature in the room - operation upon reaching 72 ° C.

KPS

The fire damper KPS can be used in combined and combined dual-purpose air ducts, as it works normally both in the open and closed state. And it can be applied as an anti-smoke or fire-retardant device.

Various models can be equipped with electromechanical locks of both domestic and foreign production (Siemens). And also be equipped with an electromagnetic or spring lock with or without additional activation thermal sensors.

The use of fire dampers will increase. In addition, choosing a reliable model can make the smoke extraction system more reliable, eliminating delays in operation.
