MOTORIZED VOLUME CONTROL DAMPER

Motorized Volume Control Dampers are very much similar to Volume Control Dampers, but are supplied with extended shaft and a wide range of Electrical actuators for operation.

Specification:

ROUND VOLUME CONTROL DAMPER

Round Volume Control Dampers are designed for quiet, efficient and reliable air volume control in ventilation systems. Circular Damper allows even distribution and control of airflow under conditions of high duct pressures. Dampers can be manual with locking quadrant and position indicator or motorized with a wide range of electrical actuators.

Specification:

Fire Damper

Fire Dampers are passive fire protection products used in HVAC ducts to prevent the spread of fire inside the ductwork through fire-resistance rated walls and floors. When the temperature rises, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to close the damper blades.

Specification:

Motorized FIRE DAMPER

Motorized Fire Dampers are very much similar to Fire Dampers. Motorized Fire Dampers are supplied with Electrical actuator for operation and they close following receipt of an electrical signal from a fire alarm system utilizing detectors remote from the damper, indicating the sensing of heat or smoke in the building occupied spaces or in the HVAC duct system.

Specification:

VARIABLE – AIR – VOLUME BOX – BYPASS

The VAV bypass system supplies a constant volume of air at a constant pressure and temperature in a single run of duct. Wall mounted thermostats are used to regulate the volume of air entering the controlled area through the Variable Air Volume boxes. Each box is equipped with a bypass balancing damper at the top to ensure that too much air does not bypass to the ceiling space. Excess air is diverted directly to the return air ceiling plenum for free or ducted return. Damper Modulation will range from full-shut-off to full-open to a mechanically set minimum air volume.

Specification:

VARIABLE – AIR – VOLUME BOX – PRESSURE INDEPENDENT

Pressure Independent Terminal units have flow-sensing devices that limit the flow rate through the box. They can control the maximum and minimum CFM that can be supplied and are therefore independent of the Static pressure in the primary air duct. Pressure independent systems can be balanced and will allow the correct airflow from each terminal

Specification:

G.I ACCESS DOOR

Access Doors are designed for use in air conditioning ductwork systems to provide access for resetting of Fire Dampers, Heaters, and Filters and to protect fire alarm panels or any other sensitive or security required equipment and for other maintenance works.

Specification :

NON RETURN DAMPER

Non Return Dampers are designed for use in fresh air intake or air exhaust openings, with twin fans in commercial and residential premises.As the room pressure increases, the blades of the pressure relief damper open up there by releasing the excess pressure in the room and as the pressure drops the blades get closed. Duct Mounted NRD Comes with a 30 mm GI Self Flange and Wall Mounted NRD comes with an Aluminum / GI Angle Frame of specified sizes.

Specification :

PRESSURE RELIEF DAMPER

Pressure Relief Damper is a type of Non Return Damper having an adjustable start-open pressure, which is capable of maintaining a relatively constant pressure at various airflows and closes upon a decrease in differential pressure

Specification:

SOUND ATTENUATOR

Sound Attenuators are used to reduce noise level between two areas while still allowing the passage of air flow. Attenuators may be designed, built and tested to suit specialized applications. They are widely used for Air Conditioning Installations, Power generator Rooms, AHU units, Fan Inlet and Discharge. Main factors for noise control measures are openings into and out of noisy environment which include the ventilation of buildings, enclosures, fan selection, equipment rooms and space constraints.

Specification:

Types:

Rectangular Sound Attenuators, Elbow & Straight Sound Attenuators, Cross Talk Attenuators, Round Silencers

ACOUSTIC LOUVER

Acoustic Louvers are used to reduce mechanical equipment noise transmitted through building openings or from openings in acoustic enclosures or barrier walls. They are widely used in Acoustical Enclosure ventilation, Generator Room Intake & Discharge vents, Pump room and Barrier wall systems. They have a relatively large surface area which compensates for their lack of depth.

Specification:

Acoustic Panel

Acoustic Panels are used to reduce noise and control sound in many different spaces. Acoustic panels meet both acoustic performance and structural durability well. All of the sound absorbing wall panels can be made from a Class A fire rated acoustic foam and there are heavy duty panels covered in perforated metal. There are Acoustic Panels for indoor and outdoor applications.

Specification:

BLACK MILD STEEL DUCT

Black Mild Steel Duct is commonly referred to as MS Duct or Kitchen Duct and it is widely used in the kitchen Ventilation Systems. Black Mild Steel Ducts are manufactured in accordance with SMACNA, SW172, ASHRAE and WPPA Standards.

Specification:

STAINLESS STEEL DUCT

Stainless Steel Duct is widely used in Laboratories, Food Processing Units and air duct systems suitable for Kitchen Extracts and Toilet extracts. Stainless Steel Ducts are manufactured in accordance with SMACNA, DW144 and ASHRAE Standards.

Specification:

GRILLES AND REGISTERS

A Grille is an air outlet or intake that consists of a square or rectangular face and neck, and is made up of stationary or adjustable louvers which may be used to deflect the air. A Register is simply a Grille which incorporates an integral damper for air volume control.

SUPPLY/ RETURN AIR GRILLE

Supply Grilles and Registers usually have adjustable louvers and are available in single or double deflection models. The single deflection type includes one set of blades in the horizontal or vertical orientation. Air pattern is adjustable in one plane only. The double deflection type includes two sets of blades in both the horizontal and vertical orientation, with air pattern being adjustable in both the horizontal and vertical planes.

Specification:

SUPPLY/ RETURN LINEAR BAR GRILLE

The Linear Bar Grille is normally used where an architectural blend of the grille to its surroundings is required. Front Blades of the Linear Bar Grille are fixed horizontally to the frame using Aluminum pipes while the rear vertical blades are adjustable.

Specification:

SUPPLY/ RETURN LINEAR SLOT DIFFUSER

Linear Slot Diffusers incorporate adjustable pattern controllers in a multi slot configuration. Adjustable pattern controllers allow horizontal left, horizontal right or vertical discharge for maximum flexibility. Typically used in ceiling installations, the linear slot diffuser is architecturally appealing, particularly when supplied in continuous lengths.

Specification:

SUPPLY/RETURN SQUARE DIFFUSER

Square Ceiling Diffusers consist of several concentric square cones assembled together to discharge air equally in four horizontal directions. Air pattern is uniform and is maintained at extremely low flows, making it ideal for variable air volume applications.

Specification:

Round Ceiling Diffuser

Round Ceiling Diffusers consist of several concentric cones suspended below the ceiling line by an outer cone and they offer radial discharge of conditioned air at low sound levels. Due to the availability of large neck sizes, the Round Ceiling Diffuser is often used where high flow capacities are required (e.g. supermarkets, gymnasiums, halls, industrial applications).

Specification:

DOOR GRILLE

They are widely used in facilities such as offices, hospitals, schools, toilets and also in place of conventional exhaust and return grilles. Door Grille comprises of a front section with inverted ‘V’ horizontal blades which helps in blocking the vision and also provides stiffness.

Specification:

EGG CRATE GRILLE

Egg Crate Grilles are designed for return and exhaust application. They can handle huge air volumes with minimal pressure drops and noise generation

Specification:

DISC VALVE

They are used for the ventilation of bathroom or kitchen etc. They are designed as a supply or return diffuser

Specification:

JET NOZZLE

Jet Nozzles are developed for large and high are such as airports, shopping centers, theaters etc. It is to ensure a long throw (25 meters) at high outlet velocities. It is used for point wise heating or cooling with the characteristic of orientation and can be rotated by electric or pneumatic control.

Specification:

SAND TRAP LOUVER
