# Vvon Technologies Limited > Engineering the future of Solar, Science and Health. Vvon is an engineering company in Bangladesh working across solar, scientific and laboratory equipment, nuclear medicine, medical equipment and education, and nanotechnology. The company is based at House-7 (Level-4), Road-1/A (Opposite to American Center), Block-J, Baridhara, Dhaka-1212, Bangladesh. Email for all enquiries: info@vvon.com.bd. Call or WhatsApp for all five verticals and general enquiries: +8801805987890. The solar offering covers VVON EPC services and solar street lighting. Modules, inverters, mounting, controls and protection are specified within an EPC proposal rather than a standalone component catalogue. Equipment pages describe the published catalogue; model configuration, availability, delivery, warranty and service scope are confirmed in a quotation. A catalogue listing is not a stock or price offer. The linked pages contain the public product and service details. Honeywell supply is limited to the MIDAS family: MIDAS, MIDAS-M, MIDAS S2 and MIDAS sensor cartridges. Withdrawn and discontinued listings are excluded from the catalogue; their URLs return HTTP 410. Perlove coverage includes the PL300B surgical-navigation robot and identified imaging models. Manufacturer family illustrations are labelled; confirm the selected model and configuration in the quotation. ## Five engineering verticals - [Solar & Renewable Energy](https://vvon.com.bd/solutions/solar): Solar EPC services and solar street lighting for industrial, commercial and institutional sites in Bangladesh. - [Scientific & Laboratory Equipment](https://vvon.com.bd/solutions/scientific): Engineering teaching laboratories, analytical instruments, materials testing, optics, sample preparation and laboratory utilities. - [Nuclear Medicine & Imaging](https://vvon.com.bd/solutions/nuclear-medicine): Nuclear medicine imaging, radiopharmacy shielding, quality assurance equipment and radiotherapy support. - [Medical Equipment](https://vvon.com.bd/solutions/medical-education): Hospital equipment, treatment chairs, clinical laboratory instruments and medical education technology. - [Nanotechnology](https://vvon.com.bd/solutions/nano): Microscopy, thin-film deposition, lithography, thermal analysis and other materials-research instruments. ## Find equipment and plan a purchase - [Equipment and solution directory](https://vvon.com.bd/solutions): Choose a vertical, then browse its laboratory categories and equipment. - [Product catalogue](https://vvon.com.bd/products): Search models and equipment across all five verticals, filter by brand or category, and build one enquiry list.
