How do I choose the right capacity for my project?

Required capacity is calculated from the full load list (motors, lighting, HVAC, etc.). In Iran, climate derating must be applied due to altitude and heat — our free calculator handles this and adds a 20% safety margin.

What is the difference between Perkins, Cummins, Volvo Penta, Caterpillar, KOHLER, and MTU?

Each brand has its specialty: Perkins for fuel efficiency, Cummins for stable instantaneous power, Volvo Penta for quiet operation, Caterpillar for heavy industry, KOHLER for smart controllers, MTU for Tier III/IV data centers. Our advisors recommend the best fit for your use case.

What does the 2-year warranty cover?

Written commitment to replace or repair on technical defect, supply of genuine parts, periodic service, and 24-hour technical support for the first two years. Service contracts can be renewed afterward.

How long does delivery and installation take?

In-stock models ship in 3–7 business days. Custom orders take 3–8 weeks depending on brand and capacity. Installation and commissioning by our team takes 1–3 business days.

Is financing or installment available?

Yes. For industrial projects, installment plans through partner banks are available. Terms depend on purchase amount, company history, and credit profile — our sales team explains details during consultation.

Do you provide service and maintenance after purchase?

Yes. We offer routine service (oil/filter changes, load-bank testing, oil analysis), emergency repair, and long-term maintenance contracts. 24-hour emergency support is active for critical situations.

What is the difference between Standby, Prime, and Continuous duty?

Standby: backup only during outages (max 200 h/year). Prime: extended runtime with variable load (no hour limit, ~70% average load). Continuous: 24/7 operation at fixed load — for remote sites and data centers.

Can I visit your workshop or warehouse?

Yes. With prior coordination, customers can visit our headquarters in Tehran, 35th Metri Gheytarie, Roshanaei St, No. 12, Unit 6 or our warehouse for visits on Azadegan Hwy to inspect and test diesel generators before purchase.
