Opening the island

Welcome to COF World

A 3D island where Cust-O-Fab equipment does its work.

Refineries, LNG, power plants, data centers and more: five districts and 18 places to fly over, with Cust-O-Fab exchangers you can open part by part.

The island is loading behind this guide. Read on, or enter whenever you like: if it isn’t ready yet, it finishes in front of you.The island is loading behind this guide. Read on, or enter whenever you like.

Where to go

What are you looking for?

Tell us what you came for and we’ll take you straight there. Every destination below opens the island at that exact view.

Not sure?

Here’s where to go

Find your industry and open its equipment.

Eleven of the island’s 18 places hold Cust-O-Fab exchangers you can open in 3D: a shell & tube and an air-cooled heat exchanger. Pick your industry and we’ll open that place on the island, with its story and its equipment. Open 3D view takes you to the unit on its own page.

Choose your industry

Mining, Space, Home and the four COF campuses have no equipment to open. They’re under Every place.

Before you go

What to expect at the door.

1
Choose
COF World asks once, on any page, whether you’d like an account. It’s free either way. An account adds the equipment challenge; without one, nothing about your visit is kept.
2
Watch
Opening the whole island plays a flyover of the five districts and 18 places; each pass takes just under five minutes. A link to a specific place skips it.
3
Take over
Any touch, click or key ends the flyover. Drag to turn and tilt the view, and right-click or double-tap a spot to center the view on it. Scroll or pinch to zoom; Shift-drag or drag with two fingers to move.

Good to know

The island is a large 3D scene: give it a moment to load, and keep a connection. Phones load a lighter version.
Home, the equipment and AR open on their own pages. Back within 30 minutes returns you to the island where you left it.
Add COF World to your Home Screen: Menu › Help › Install COF World shows the steps.
On a desktop, press / to find a place by name, industry or equipment.
Photo mode hides the controls for a clean screenshot, and every place has a Share link that reopens it.
