VFD Panel Installer Support in Makati for Pump Rooms and Plant Rooms

When a Makati facilities engineer searches for a VFD panel installer, the request usually bundles three separate scopes that get quoted by three different parties: the panel itself, the mechanical tie-in to the pumps or fans it will drive, and the electrical installation work on site.

The first scope is the enclosure, the variable frequency drive, the contactors, the overloads, the control logic, and the terminal layout. The second is the mechanical tie-in. The third is the on-site electrical work: the incoming feeder, the conduit runs, the terminations, the earthing, and the sign-off under the Philippine Electrical Code. JOHOB Hardware Trading supplies the first scope and supports the third. We build and deliver the panel to your specification, we provide the wiring diagrams and component datasheets your electrician needs to terminate correctly, and we answer sizing and configuration questions during installation. The physical installation and the code sign-off are executed by your own licensed electrical contractor, either your in-house building maintenance team or the contractor already engaged on the project. Being explicit about this split matters, because a quotation that silently assumes someone else is doing the terminations is how Makati retrofit projects end up two weeks late. Ask any bidder to state, in writing, which of the three scopes their number covers before you compare prices.

JOHOB supplies the panel assembly and the pump package it controls. Our control panels are built by Chutian using Inovance variable frequency drives, and they are matched to the pump set on the same quotation so the drive rating, the motor rating, and the overload settings agree before anything ships. On the pump side we source from Grundfos, DAB, and Speroni, and from CDL for engineered vertical multistage units, which means a Makati booster or transfer application can be quoted as a single package with our commercial booster pumps rather than as a panel from one vendor and a pump from another. The VFD duplex pump control panel is the configuration most Makati booster retrofits land on. What we hand over with the panel is the documentation set: the schematic, the bill of materials with component brands and ratings, and the certification records covered in a later section. What your electrical contractor does is everything from the incoming breaker onward: the feeder sizing, the conduit and cable tray routing, the glanding and terminations at the panel, the earthing, the motor cable runs, and the final testing and commissioning under the Philippine Electrical Code. We stay reachable through that work, and we respond to RFQs and technical queries within one business day. If your building has no electrical contractor currently engaged, say so in the RFQ so the scope split is written into the quotation from the start rather than negotiated after delivery.

Not every Makati pump room needs a VFD, and specifying one where it adds no value raises both the panel cost and the number of failure points. A VFD panel earns its cost where the demand actually varies: a high-rise domestic water booster set that sees a morning and evening peak and a near-zero overnight draw, a chilled water pump on a floor-by-floor load, or a transfer pump that would otherwise cycle a contactor hundreds of times a day. The demand-profile test is covered in full in our VFD versus fixed-speed pumps guide. Where the load is fixed and the run is continuous, a star-delta starter usually does the job at a lower delivered cost, and a smart drive enclosure (SDE) sits between the two when you want soft starting and basic protection without full speed control. A motor control centre is the right answer when you are feeding and protecting several motors from one lineup rather than one motor from one panel; our MCC panel fabricator in the Philippines page covers that scope. For outdoor or exposed locations, IP55 outdoor rated VFD panels carry the enclosure rating that decision drives. If you are unsure which applies, send the pump curve, the motor nameplate, and the demand profile with the RFQ and we will specify against those rather than against a guess.

The Makati building stock that drives VFD panel demand falls into a few recognisable categories, and each one changes the specification in a specific way. High-rise office towers and mixed-use podiums run domestic water boosters where the daily demand swing is large enough that speed control pays back in both energy and reduced pump wear, and they almost always want a duplex arrangement so a single drive fault does not take the building off water; the same logic applies to condominium booster pump replacement in Manila. Hotels and serviced residences carry the same booster requirement plus hot water circulation, and they weight quiet operation and duty sharing heavily. Hospitals and clinics add redundancy requirements and want the control logic to fail to a safe, running state rather than to a stop. Commercial laundries and food processing plants drive process pumps and often pair the panel with steam and condensate equipment on the same project. Neighbouring CBD districts run the same building stock, which is why our commercial pump supplier page for BGC and Taguig reads like this one. JOHOB supplies nationwide across NCR, the rest of Luzon, Visayas, and Mindanao, including PEZA, SBMA, and Clark locators, so a Makati head office specifying for a provincial site can run both under one supplier. Tell us the facility type in the RFQ, because it changes the redundancy and control recommendation more than the kilowatt rating does.

Procurement in Makati commonly asks for certification evidence before releasing a purchase order, and a panel quotation without it stalls at the approvals stage. The panels we supply carry CE marking on the electrical assembly, are built by a manufacturer operating an ISO 9001 quality management system, and use components that are TUV SUD tested. Those three records cover what most Metro Manila building administrators, property managers, and corporate procurement teams request in a technical submittal. What they do not cover, and what no supplier certificate can cover, is the installation itself. Compliance of the installed work with the Philippine Electrical Code is established on site by the licensed electrical contractor who performs and signs off the installation, not by the panel vendor. JOHOB is an equipment supplier: we provide the panel, the schematic, the bill of materials, the component certification records, and local warranty and after-sales support on what we supply. We do not perform the electrical installation and we do not issue installation sign-off. Stating this plainly in your bid comparison is useful, because a bidder who implies otherwise is either quoting a scope they do not hold or has bundled a subcontractor into the number without telling you. Ask for the certification pack up front and confirm it matches the components actually being delivered.

Pricing is quote-based and we do not publish panel prices, because the drive rating, the enclosure specification, the control logic, and the pump pairing move the number too far for a list price to be honest. Two timing bands apply. Standard configurations built from stock components run 21 to 35 days. Made-to-order builds, meaning non-standard enclosure ratings, unusual control sequences, or larger MCC lineups, run 45 to 90 days. Plan the Makati site schedule against the made-to-order band unless we have confirmed your configuration is ex-stock, because a panel that arrives after the electrical contractor has demobilised costs more than the panel. On tax, the standard 12 percent VAT applies to VAT-registered buyers. Locators inside PEZA and SBMA zones and registered exporters qualify for zero-VAT treatment, so state your registration status in the RFQ rather than discovering it at invoicing. A complete RFQ contains: the motor kilowatt rating and full load current, the supply voltage and phase, the pump make and model or curve if the pump is already installed, the required enclosure rating and whether the location is indoor or outdoor, the number of pumps and whether duplex duty sharing is needed, the delivery address, and your VAT or PEZA status. Send that set and we respond within one business day.
