About Denyo

Japanese engineering since 1948

Denyo is one of Japan's leading manufacturers of engine-driven generators, welders and air compressors. Since 1948 it has also developed mobile lighting, water-related equipment, self-propelled work lifts and primary and emergency generating sets, and it sells in more than 100 countries.

Denyo offers over 500 gasoline and diesel generator models from 0.45 kVA to 1,100 kVA, in trailer-mounted and stationary versions, known for durability, fuel efficiency and soundproofing. denyo.co.jp

Why Denyo

Soundproof. Reliable. Fuel saving.

The three reasons customers across Pakistan choose Denyo generators from BTI.

Soundproof

Every DCA unit sits in a soundproof steel canopy. Running noise starts from 58 dB(A) at 7 metres, quiet enough for homes, offices and hospitals.

Reliable

Japanese-engineered, with a brushless alternator and AVR for stable voltage within ±0.5%. Automatic shutdown protects the engine, and more than 13,000 units were installed across Pakistan by 2018.

Fuel saving

Efficient Japanese diesel engines keep running costs low. A 13 kVA DCA uses about 2.4 litres per hour at 75% load and runs up to 12 hours without stopping.

Generators
