Product Description

Motorized Multi Louver Dampers

We offer our clients a wide range of Multi Louver Dampers. These Multi Flap Dampers are used in much industrial application like isolation, modulation service and pre-spinning of duct air. Further these Louver dampers are also used as prevention of ingress of rain water, to reduce stack effect during period shutdowns, to minimize heat loss from the boiler and many more.

Advanced Blade Operation for Precise Airflow Control

Choose between parallel or opposed blade options to suit diverse HVAC needs. The double skin aerofoil blade design enhances rigidity and minimizes resistance, resulting in consistent airflow and low noise performance. This flexibility makes installation easy across commercial and industrial environments, allowing precise management of ventilation systems.

Superior Sealing and Low Leakage Performance

Outfitted with EPDM or neoprene gaskets, these multi louver dampers provide an excellent air seal, aligning with international IS/BS leakage class standards. This ensures reduced energy loss and improved HVAC system efficiency, making them reliable components for demanding environments.

Durable Construction and Customization

Frames of 1.2 mm to 2.0 mm thickness are available, constructed from materials like aluminium, galvanized, or mild steel to match application needs. Surface finishes include powder coated or galvanized, offering enhanced durability and corrosion resistance. Customizable options allow integration into any duct or wall-mounted setting.

FAQs of Motorized Multi Louver Dampers:

Q: How do motorized multi louver dampers improve airflow management in HVAC systems?

A: These dampers use parallel or opposed blade operation to regulate airflow precisely. The double skin aerofoil blades minimize resistance and noise, enhancing air distribution for HVAC systems, air handling units, and industrial ventilation.

Q: What leakage class do these dampers comply with, and what benefits does this provide?

A: The dampers feature low leakage in accordance with IS/BS standards, supported by EPDM or neoprene gaskets. This leads to reduced energy losses, improved air sealing, and higher operational efficiency in building automation and ventilation applications.

Q: When should I consider customizing the dampers size, frame thickness, or material?

A: Customization is recommended when specific installation requirements, airflow capacity, or mounting constraints exist. Frame thickness (1.2 mm to 2.0 mm) and material selection (aluminium, galvanized, or mild steel) are tailored by application needs and environmental demands.

Q: Where are these motorized multi louver dampers typically installed?

A: They are suited for wall or duct mounting in commercial buildings, industrial plants, and air handling units. Installation locations are conveniently adaptable following manufacturer guidelines for optimal system integration.

Q: What optional accessories are available with the MLD Series dampers?

A: Accessories include electric actuators, mounting flanges, position indicators, end switches, manual override, and position feedback. These enhance functional reliability and support advanced building automation systems.

Q: How is maintenance handled for these dampers and what are the service requirements?

A: Designed for minimal maintenance, these dampers offer easy access for service, helping reduce downtime and ensuring long-term operational continuity. Regular inspection as guided by the manufacturer maintains optimal performance.

Q: What efficiency and power consumption can be expected from the motorized multi louver dampers?

A: These dampers are engineered for up to 90% efficiency with low power consumption. Motor power ranges from 0.5 HP to 2 HP, and speed varies based on actuator selection, aligning with modern energy management strategies.
