Acoustic Performance

How Quiet Are Ruwanara Silent Generators?

Many hotels and outdoor venues in Sri Lanka reject noisy generators. Our canopies use 50mm acoustic foam insulation and hospital-grade silencers to keep sound levels below conversational speech.

Acoustic Sound Level
< 68 – 70 dB @ 7m

Decibel (dB) Comparison Scale

Whisper / Quiet Library 35 dB
Ruwanara Silent Canopy Genset (Speech Volume) 68 dB
City Traffic / Vacuum Cleaner 75 dB

Electrical Engineering Tool

Calculate Your Required Generator Size

Choosing the right generator size is more than just calculating total wattage. For maximum fuel efficiency and reliability, generators should run at 60–75% capacity, so we always include a 25% safety margin. A standard 300-guest event runs smoothly on 100 kVA, while adding large LED screens requires 150 kVA. To remove the guesswork, simply use our interactive calculator below. Select your planned equipment, and the tool will instantly recommend the optimal generator model, estimated fuel burn, and an indicative daily rate.

Frequently Asked Questions

Clear operational answers on billing, technicians, noise levels, and delivery.

Are these generators quiet enough for weddings and speech ceremonies?
Yes. All our event generators are factory soundproofed acoustic canopy units measuring under 68–72 dB at 7 meters distance. They are widely used in premium hotel lawns, residential gardens, and golf clubs without causing noise disturbance to guests or speeches.
How is fuel billed during the rental period?
The generator arrives with a 100% full fuel tank. The opening meter reading is signed off with you on delivery. Upon completion, the fuel consumed is calculated at actual official CPC/LIOC diesel pump prices. You only pay for what your event actually used.
Is an operator included, and what does the operator do?
A trained operator is included for all event hires. The operator oversees cabling connections, starting/stopping, monitoring phase loads, adjusting voltage, and managing continuous safety.
How early should we book for peak wedding and festival seasons?
For peak dates (December holiday season, April, and auspicious wedding months), we recommend booking 1 to 2 weeks in advance to lock in your preferred kVA capacity. For emergency power cut situations, we dispatch on immediate notice in Colombo.
