Products

Specify the package. Or the complete system.

Merlin sells the controls package as a standalone product and as the heart of a complete fan array. Same engineering. Different scope. Pick the one that fits how you build.

The decision

How do you build?

Merlin Controls (standalone)

You bring the AHU. We bring the brain.

▸OEM Reps replacing fan sections in existing AHUs
▸Rep platforms standardizing one controls platform across multiple OEM product lines
▸OEM AHU manufacturers integrating Merlin controls into their cabinet design

A field-installable Control Panel and QCB that integrates with any AHU's installed EC fan array. On retrofits, we can supply the bulkhead too.

Merlin Fan Array (complete system)

We bring everything. You commission and run.

▸Consulting engineers specifying a fan array as part of a custom or built-up AHU
▸Mechanical contractors installing a complete factory-tested system
▸Projects where one PO, one shipment, and one point of accountability is the point

We build the bulkhead, integrate your choice of EC fan brand, install the controls package, factory-test, and ship.
