VFD Panel Supplier Philippines: Chutian Panels with Inovance Drives, Delivered Nationwide

A variable frequency drive panel is the enclosure, the drive, and the control logic that ramp a motor to match real demand instead of running it flat out. JOHOB Hardware Trading supplies these panels as equipment, not as a construction service, and that distinction shapes everything downstream in your procurement.

On a booster set a VFD panel means the pump follows building pressure through the day rather than cycling hard against a pressure switch. On a transfer or submersible set it means a controlled start that stops hammering the mechanical seal and the discharge piping. What arrives on site is a built and tested panel with its documentation set, ready for your licensed electrical contractor to mount, terminate, and energise. JOHOB is not PCAB-accredited, so the physical installation, termination, and any permit work stays with your contractor, and we scope the supply so that handover is clean rather than ambiguous. Buyers reaching this page are usually one of three people: a facilities engineer replacing a failed panel in a live pump room, a mechanical contractor pricing a package for a bid, or a procurement officer at a PEZA or SBMA locator who needs the correct tax treatment on the purchase order. All three need the same four answers before they can move: what the panel is built from, what certification travels with it, how long it takes to arrive, and what the tax line looks like. The rest of this page answers those in order, with the numbers stated rather than promised on a call.

Not every motor needs a drive, and specifying one where a starter would do adds cost and a failure point. JOHOB supplies four panel types across the range so the choice can be made on load behaviour rather than on what a supplier happens to stock. VFD panels suit variable demand: booster sets serving occupancy that swings through the day, transfer pumps that would otherwise short cycle, and process loads where flow or pressure is the controlled variable. Star-delta panels suit fixed-speed motors that only need inrush current reduced at start, which covers a large share of transfer and fire-adjacent duty where the motor runs at one point on its curve. SDE panels handle the direct starting cases where the supply can take the inrush and the mechanical shock is acceptable. For MCC panel supply in the Philippines, the MCC lineup is the aggregation layer, bringing several motor starters and drives into one assembly with common incoming protection, which is what a plant room or a process line usually needs once the motor count climbs past a handful.

Panels are built by Chutian using Inovance variable frequency drives, and JOHOB is explicit that these are partner-factory sourced rather than fabricated in-house. The duplex VFD pump control panel with Inovance drives for lead and lag pump alternation is supplied for the booster and pressure applications that make up most of our pumping work, and IP55 outdoor rated VFD panels cover installations exposed to weather. For the pump-side view of the same decision, our hub on VFD pump control panels maps panel families to pump duties. If you are undecided between a drive and a starter, send the motor nameplate and the duty description and we will spec against the load rather than against a catalogue page.

Certification is where most panel enquiries stall, usually because the paperwork arrives after the equipment and by then a consultant has already flagged the submittal. JOHOB supplies panels carrying CE marking on the electrical build, from manufacturers operating an ISO 9001 quality management system, with TUV SUD tested components in the assembly. Those three marks cover the questions that come up in a typical PH submittal review for commercial, industrial, and institutional projects, and they are the marks we will state in writing on the quotation rather than describing loosely in an email. Two clarifications worth making, because both come up: WRAS certification applies to our water storage tank panels supplied under the TankSmith sister brand and is a potable water contact certification, so it is not a claim that belongs on an electrical panel, and JOHOB does not hold PCAB accreditation, so no certification we supply should be read as a contractor licence. Ask for the certificate set at RFQ stage rather than at delivery. When you tell us at enquiry which certificates your consultant, your PEZA locator compliance team, or your insurer will want to see, we specify to that requirement from the start instead of trying to retrofit documentation onto a panel that is already built. That single step is the most common reason a panel submittal clears on the first pass instead of the third, and it costs nothing at the quoting stage.

Standard ex-stock configurations run 21 to 35 days. Made-to-order builds, meaning non-standard enclosure ratings, unusual kW ratings, specific component brands called out by a consultant, or integration into a larger MCC lineup, run 45 to 90 days. Those bands are the actual planning numbers, not a best case, and they are what you should carry into your programme when a VFD panel sits on the critical path ahead of pump commissioning. On tax treatment, 12% VAT applies to VAT-registered buyers on the domestic supply. Locators inside PEZA and SBMA, and registered exporters, are eligible for zero-VAT treatment, and we prepare the quotation on that basis when you tell us your registration status at enquiry. Getting this right at RFQ stage matters more than it sounds: a quotation issued with 12% VAT to a PEZA locator has to be reissued, and a reissue on a purchase order that is already through an approval chain costs more calendar days than the tax difference is worth. JOHOB responds to RFQs within 1 business day. Pricing is quote-based and we do not publish price lists, because panel cost moves on motor kW, enclosure rating, drive selection, certification scope, and delivery region, and a published number would be wrong for most of the enquiries that reach this page. Send the specification and you get a real figure, not a range.

JOHOB delivers nationwide across the Philippines, covering NCR, the rest of Luzon, Visayas, and Mindanao, and we regularly supply into PEZA, SBMA, and Clark locators where the zero-VAT and gate documentation add a layer that a general supplier often has not handled before. Delivery region affects freight and therefore price, so it belongs in the RFQ alongside the motor data. For Makati pump rooms and CBD building retrofits, our VFD panel installer support page for Makati pump rooms covers the access and scheduling constraints specific to that district. What separates a supplied panel from an imported one is what happens after it lands. Panels supplied by JOHOB carry local warranty and after-sales support, which means a support relationship inside the Philippines rather than a factory contact in a different timezone and a shipping problem when a drive needs replacing. JOHOB also supplies the mechanical equipment the panel controls, including commercial booster pumps, transfer and submersible pumping systems, hydropneumatic pressure tanks, and steam and boiler system equipment. When the panel and the pump come from the same supplier, the control logic is specified against the actual pump curve and the responsibility for making the two work together does not sit in a gap between two vendors. That single-supplier route is how most of our booster and pressure system packages are delivered, and it removes the most common commissioning dispute on pump room projects.

The gap between a first quotation that is usable and one that has to be redone three times is almost entirely about what was in the enquiry. Send these eight items and the first quotation will be close enough to price a bid against. First, motor kW rating and voltage, taken from the nameplate rather than from the drawing, because the two disagree more often than people expect. Second, number of motors and whether they run duty and standby, duty and assist, or simultaneously. Third, the application, meaning booster, transfer, submersible, process, or general motor control. Fourth, whether you want alternation, which is what makes it a duplex panel. Fifth, the installation location, indoor plant room or outdoor exposed, since that drives the enclosure specification. Sixth, delivery region and site, so freight is priced correctly. Seventh, your VAT status, meaning VAT-registered, PEZA or SBMA locator, or exporter. Eighth, the certificate set your consultant or compliance team requires.

If a consultant has issued a specification, send the relevant section rather than retyping it, since we would rather quote against the document that will be used to review the submittal. Whether the duty needs a drive at all is covered in our guide on when to use a VFD versus a fixed-speed pump, and the flow and head numbers behind the panel sizing come from how to size a booster pump for a commercial building. The full panel range sits in our electrical and controls category. RFQs are answered within 1 business day. Where the specification is incomplete we come back with the specific missing item rather than a generic form, because a targeted question turns around faster than a blank template does.
