Overview

Diesel generator sets are the backbone of industrial emergency and standby power — the first line of defense against grid failure for hospitals, data centers, commercial buildings, hotels, manufacturing plants, and telecom sites. Also used as prime power for off-grid or unreliable-grid locations. Our gensets are factory-matched units pairing proven diesel engines (Cummins, Perkins, Volvo Penta, Weichai) with brushless synchronous alternators, integrated on a steel base frame with fuel tank, radiator cooling, silencer, and AMF (Auto Mains Failure) controller. Available as open sets (for indoor plant rooms) or soundproof weatherproof canopies (for outdoor installation). Capacities from 50 kVA for small buildings up to 3,000 kVA for data centers, hospitals, and industrial facilities. Standard 10-15 second startup-to-full-load response on AMF trigger.

What Determines Your Quote

Every quote is engineered to your operating requirements. Pricing depends on:

  • Configuration: capacity, flow rate, head pressure, motor size, voltage/phase, materials of construction
  • Certification tier: WRAS-cert vs commercial-grade, ASME stamping, IP rating for panels
  • Delivery region: nationwide (Metro Manila, Luzon, Visayas, Mindanao); freight varies by destination
  • Installation scope: supply-only, supply + mechanical install, or full turn-key with commissioning
  • Payment structure: milestone terms tailored to project timeline (typically 40/30/20/10 for engineered scopes; 70/30 for equipment supply)
  • Tax status: 12% VAT applies to VAT-registered buyers; Zero-VAT available for eligible PEZA / SBMA locators and exporters

Formal written quote within 3 to 5 business days of complete spec confirmation. Response within 1 business day to every inquiry.

Frequently Asked Questions

What certifications come with a diesel generator set?

Every diesel generator set we supply carries CE marking, is rated and tested to ISO 8528 (the international standard governing genset performance classes), and comes from an ISO 9001:2015 certified production line. Emissions compliance options cover EPA Tier 2 and Tier 3, with EU Stage V available where a site or financing requirement demands it; tell us your regulatory context and we match the engine build accordingly. Material test certificates and the factory inspection report, including the load test record for your specific unit, are included in every shipment as part of the delivery documents. That paperwork covers what your electrical engineer, permit office, and insurer typically ask for, so your compliance file is complete on delivery day. Any project-specific certification beyond these is confirmed in the written quotation, so raise it during inquiry.

What is the standard lead time for a genset?

Standard lead time for a diesel generator set runs 45 to 90 days from down payment. Common standby ratings in popular voltage configurations sit at the shorter end of that range, while large units toward 3,000 kVA, paralleling packages with load-sharing controls, or non-standard canopy and fuel tank arrangements take longer because of factory build scheduling. The exact delivery schedule for your configuration is confirmed in the written quotation, which we issue within 3 to 5 business days of receiving your load requirements. If your facility has a fixed energization or inspection date, flag it during inquiry: preparing the concrete pad, cabling, and transfer switch works in parallel with the genset build is the standard way to compress the overall timeline, and we coordinate those milestones with your contractor. Response to your initial inquiry comes within 1 business day.

Do you deliver gensets to Luzon, Visayas, Mindanao, SBMA, and Clark?

Yes, we deliver diesel gensets nationwide: Metro Manila, all Luzon provinces, Visayas, and Mindanao, including regular deliveries into SBMA, Clark, and PEZA industrial estates. Gensets ship as complete factory-assembled units on their base frames, so the delivery plan centers on truck access and offloading: smaller canopy sets come off with a standard boom truck, while units in the hundreds of kVA and above need a crane at site, which we specify in advance. For Visayas and Mindanao sites we arrange inter-island freight and coordinate the offloading requirements as part of the quotation, so the price you see is the landed cost to your facility. If your site is inside a locator zone such as SBMA or Clark, mention it at inquiry and we prepare the delivery documents to match your zone's gate pass procedures.

Is installation included, or is this supply-only?

Both scopes are available and quoted separately: supply-only, or supply plus installation and commissioning. Supply-only means the genset arrives as a complete unit with manuals, wiring diagrams, and the factory load test record, and your own electrical contractor handles the pad, cabling, transfer switch, and startup. Supply-plus-install adds our team for positioning, fuel and exhaust connections, control wiring to your ATS, first start, load testing on site, and operator orientation, which most buyers choose for standby systems protecting critical loads like hospitals, data centers, and production lines. Civil works for the concrete pad and the incoming electrical infrastructure are normally by others in either scope, and the written quotation states the exact boundary line by line. Tell us your preference at inquiry and we price both options side by side so you can compare.

What warranty does a diesel generator set carry?

The warranty term for your specific genset is confirmed in the written quotation, since coverage depends on the engine and alternator package, the rating (standby versus prime power), and expected running hours. What every unit includes as standard: the warranty certificate, material test certificates, and the factory inspection and load test reports all ship with the delivery documents, so your compliance and maintenance records are complete on day one. Warranty service runs through our team as your single accountable point of contact, covering both the engine and alternator sides of the set rather than splitting responsibility between component brands. Standard exclusions are the usual industry ones: consumables such as filters, belts, and batteries, plus damage from contaminated fuel or skipped preventive maintenance. We review the full inclusions and exclusions with you before you sign, so there are no surprises at claim time.

Can you customize a genset to a non-standard specification?

Yes, gensets are configured to order across the 50 kW to 3,000 kVA range, and non-standard requirements are routine. Common customizations include extended-runtime fuel tanks beyond the 8 to 24 hour base tank, soundproof weatherproof canopies engineered to specific noise limits, paralleling and load-sharing packages for multi-unit plants, heat-exchanger cooling for large indoor installations, and voltage or frequency configurations matched to your facility, including 50 Hz and 60 Hz builds. To spec a custom unit we need your load profile (running and starting loads), the duty type (standby or prime power), site conditions, and any noise or emissions constraints. Send those details and we return a specced quotation within 3 to 5 business days, with a response to your initial inquiry within 1 business day. Custom builds extend the factory schedule, and the exact lead time is confirmed in the written quotation.
