Overview
Our VFD duplex pump control panels are the brain of any modern water distribution system. The Variable Frequency Drive adjusts motor speed in real-time based on demand — when water usage drops, the pump slows down instead of cycling on/off. This delivers constant pressure, reduces energy consumption by 20-35%, and dramatically extends motor life. The duplex configuration runs two pumps in lead/lag alternation — one runs while the other stands by, with automatic switchover for even wear distribution and zero-downtime redundancy. Full PLC automation with 7" color touchscreen for real-time monitoring, alarm history, and parameter adjustment.

Who Typically Buys This
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

Frequently Asked Questions
What documentation comes with each panel?
Every panel ships with an operation manual, complete electrical schematic, and wiring diagram, plus the VFD parameter list after commissioning. This documentation package is included in the price and covers what your electrician and permit inspector need.
Can you build custom triplex or higher configurations?
Yes. Custom duplex and triplex panels in IP54 or IP65 enclosures are engineered per requirement with a 45 to 75 day lead time. Send us your motor sizes, control philosophy, and site conditions and we return a specced quotation with drawings.
What protection features are standard?
Phase failure protection, motor overload protection, soft-start / soft-stop, emergency stop, and main disconnect are standard on every panel, along with auto-alternation and lead-lag control for even pump wear. These are not optional extras.
What certifications do the panels carry?
Every panel carries CE marking and is built under an ISO 9001:2015 quality management system, with assembly practices aligned to the IEC 61439 standard for low-voltage switchgear and controlgear assemblies. These references matter to consultants and building inspectors because they cover how the enclosure, wiring, and protective devices are put together, not just the individual components inside. Each shipment also includes factory inspection reports and material test certificates as standard, alongside the operation manual, electrical schematic, and wiring diagram that accompany every panel. If your project consultant requires specific certificate copies for submittal or permit purposes, tell us at the inquiry stage and we include the required copies in the document package: the complete document list for your order is confirmed in the written quotation, and quotations are released within 3 to 5 business days of your inquiry.
How long does a panel take to deliver?
Standard duplex VFD panels for motors up to 11 kW per pump run 21 to 35 days from down payment. Larger duplex panels in the 22 kW class run 30 to 45 days, while custom duplex and triplex configurations engineered to your specification run 45 to 75 days because drawings are prepared and approved before fabrication starts. These timelines cover fabrication, factory testing, and inspection: the panel is verified before it leaves the factory, and the inspection reports are included in the shipment documents. The confirmed lead time for your specific configuration is stated in the written quotation so you can plan your pump room construction schedule around a committed date. If your project has a hard deadline, tell us upfront and we confirm whether the schedule is achievable before you commit to a purchase order.
Can you deliver panels to provincial sites?
Yes. Panels are delivered across Metro Manila, all Luzon provinces, the Visayas, and Mindanao, including regular deliveries into SBMA, Clark, and PEZA industrial estates where gate pass and security coordination are part of the routine. Each panel is packed upright in a braced crate with moisture protection, which matters for sensitive electrical equipment travelling long distances by inter-island freight, and it is checked against the packing list before dispatch. Freight cost depends on panel size, weight, and destination, so it always appears as its own separate line in the written quotation instead of being folded into the equipment price. Include your complete delivery address and site conditions (ground floor pump room, basement, or upper floor) when you inquire: we respond within 1 business day and release the complete quotation within 3 to 5 business days.
