Workshop Fit-out

Three Phase Power for Workshops: Checked Too Late

Three Phase Power for Workshops

Equipment lists get compared line by line. The electrical supply that has to carry all of it together usually gets checked once the crates arrive — which is the most expensive possible moment to discover a shortfall.

Three phase power for workshops is not a compatibility footnote. It is a design input that determines what you can install and when you can install it.

The published supply requirement

The specification appears identically across the range. The electro-hydraulic chassis puller, the INTECH CR 700, publishes a 220/380 V supply.

The custom booth range publishes 380 V three-phase at 50 or 60 Hz, with total electrical power from 11 to 50 kW depending on the build.

That kW range is the number to carry into a conversation with an electrical contractor. It is wide enough that two different booth builds impose meaningfully different demands on the same building.

Add the loads that run together

Individual ratings are easy to find. The number that matters is what runs simultaneously during a normal working hour.

The published figures make that calculation possible: 17 kW total on the highest-extraction booth, with two 7.5 kW turbine fans inside that total; 5.5 kW total on the enclosed preparation room; 5.5 kW on the open preparation platform.

Sum the ones that overlap in your workflow. A booth curing while a preparation station runs beside it is a normal condition, not a worst case, and it is the condition your supply has to serve.

Compressed air is the parallel question

Some equipment substitutes one utility for another, and knowing which is which changes what you have to build.

The pneumatic chassis puller, the INTECH CR 500, runs on compressed air at 0.6–0.8 MPa; its electro-hydraulic counterpart, the INTECH CR 700, carries the same four towers without compressed air.

So the same job can be specified as an electrical load or as a compressed air load. Which is cheaper depends entirely on what your building already has, and that is a site question rather than a product one.

Site readiness is a contractual position

Our published terms are explicit: the client prepares the site before delivery or installation — floors, electrical and mechanical services, ventilation requirements, and compliance with applicable safety and regulatory requirements — according to the drawings and technical requirements provided.

Any delay or damage arising from site unreadiness is the client’s responsibility alone, and additional costs such as crew rescheduling or storage are charged to their account. Civil works and services sit with the client, and we carry them out by agreement through a subcontractor network when the client asks.

We inspect the site before installation and survey the requirements, which is where a supply shortfall should surface — well before a delivery date is fixed.

Common questions

Does frequency matter for equipment selection?

It is specified rather than assumed. The custom range publishes 50 or 60 Hz, so state your supply frequency in your enquiry rather than leaving it to be discovered.

What if my supply cannot carry the full list?

Then the equipment selection changes, or the installation is phased, or the supply is upgraded. All three are legitimate — but only if the constraint is known at quotation stage rather than at delivery.

Are warranty claims affected by supply quality?

Yes. The manufacturer’s warranty published in our terms excludes faults arising from voltage fluctuation or poor installation wiring, which makes supply quality a commercial issue as well as a technical one.

What to send with your enquiry

Your supply voltage and frequency, main breaker rating, existing connected load, and whether a compressed air network already exists. Then request a quotation.

A technical question about a specific machine?

Send us the dimensions and the operating conditions, and we will answer with the configuration that fits them.
