Frequently Asked Questions
What does OWNOVA ENGINEERING LTD. actually do?+
We supply, install, maintain and repair elevators and diesel generators for residential, commercial, institutional and industrial buildings in Bangladesh, and we stock spare parts for both product lines. Our work follows a consistent lifecycle: consultation & site survey, supply & installation, testing & commissioning, then ongoing maintenance, spare parts and repair/modernization for the life of the equipment.
Which areas do you serve?+
We are based in Motijheel, Dhaka, and Dhaka is our primary service area for installation and maintenance response times. We also take on generator and elevator supply projects elsewhere in Bangladesh — tell us the project location on the inquiry form and we'll confirm feasibility and timeline during the site survey.
How quickly will you respond to an inquiry?+
We typically respond within 6 working hours for elevator and generator inquiries in Dhaka. Submit the contact form or call us directly, and our team will follow up with next steps for a site survey or quotation.
How do I get a quotation for an elevator or generator?+
Submit your requirement through the contact form with your building type, expected usage (number of floors and passengers for elevators, or load and backup duration for generators) and location. Where useful, we'll schedule a site survey before finalizing a quotation, since capacity, shaft/space constraints and installation conditions affect the right recommendation.
What elevator types do you offer?+
Passenger, Home/Villa, Hospital/Bed, Cargo/Freight, Panoramic/Glass, MRL (machine-room-less), Car Lift/Vehicle, Dumbwaiter, Capsule/Observation, Building Hoist and fully Customized elevators. See the Elevators page for a description of each type and its typical use case.
How do I choose the right generator capacity for my building?+
Generator sizing depends on your total connected load and which loads must run during an outage. As a starting point we group generators into four tiers — Small (10-50 kVA) for homes and shops, Mid (100-350 kVA) for offices and clinics, Large (500-1000 kVA) for malls and factories, and Industrial (1250-2000 kVA) for full plant backup. Share your load list with us and we'll confirm the right tier before quoting.
Do you offer maintenance contracts, or only one-off repairs?+
Both. We provide ongoing Annual Maintenance Contracts (AMC) for elevators and generators, covering scheduled servicing and priority breakdown support, as well as one-off repair, spare parts supply and modernization for equipment we did not originally install.
Can you service or supply spare parts for elevators/generators you didn't install?+
Yes. Our spare parts and repair services cover both equipment we supplied and third-party installations, including traction machines, controllers, safety components, doors and generator components such as engines, alternators and controllers.
What safety and control standards do your elevators meet?+
Our controller and inverter systems are EN81-20 compliant and include features such as ARD rescue operation and IoT-based monitoring. Safety components — overspeed governors, safety gear, fire-rated doors and full-height light curtains — are specified according to the elevator type and building requirements identified during the site survey.
I have a question that isn't answered here — how do I reach you?+
Call +8801817-970000, email [email protected], or use the contact form and we'll respond within 6 working hours. Our office is at 28/1 Toyenabee Circular Road, Motijheel, Dhaka-1000.
