The MKSA Verticle Axis Wind Turbine (VAWT) We Build The Direct Wind Future. Rated Power 2kW
A renewable energy solution for your power needs.

MKSA-2

Direct Wind Limited is the first company to have built a Vertical Axis Wind Turbine (VAWT) in Bangladesh. The MKSA-2 is capable of generating 2 kilowatts of power. Due to its quiet operation and relatively low rotational speeds compared to horizontal axis wind turbines, the VAWT is ideal for urban and rural applications. The low rotational speed makes it safer for installing the product in populated areas. Another optimal feature of the VAWT is its multi-directional function. In other words, the blades will rotate regardless of wind direction, thereby increasing its power generation capacity all year round.

The MKSA VAWTs provide an affordable, quiet, and easily maintained low RPM wind-powered solution for your renewable energy needs. Whether for urban or rural use, the MKSA-Series is one of the least environmentally intrusive renewable energy applications. With a 4.65 sq m footprint, the MKSA-2 may be placed in a corner of the rooftop or in a garden location, taking up very little space for its installation.

Installation

Installation

The MKSA-2 VAWT can be installed on reinforced concrete roofs. The turbine is attached directly to the surface of the roof using concrete wedge anchors or royal bolts. High tension steel cables may be used to further strengthen the structure. The roof is not modified or damaged in any way. No crane is needed for the installation, making it relatively easy to install without using high-skilled labor and within a short time.

The turbine may be installed on top of residential homes, skyscrapers, commercial buildings, and on the ground at customer sites. Using this system, the turbine may also be installed in telecom towers, in parks, along highways, in industrial parks and factories, in off-grid rural locations and along coastal areas and river banks.

Direct Wind will install the unit and ensure the operation of the MKSA VAWT at cost. The customer also has the option to install the system if they so desire. We offer maintenance for the first three years for customers in the greater Dhaka area. For installations outside Dhaka, we will train local technicians or customer’s own personnel to perform maintenance.

Design Life

Design Life

Once the product is purchased and installed at the customer site, it is expected to last and provide low-cost energy for a long time. The main capital expenditure, namely the wind turbine, complete with the energy generation assembly, is built to last 20 years straight. No replacement of bearings is expected within the first 7 years. The third and last component, namely the control box is expected to last 6 years with constant use. See the Specification Sheet for a detailed description of the MKSA machine.

We welcome you to take the initiative and integrate this pioneering Bangladeshi product into your home or business.
