In-Row Cooling Units

Cooling at the source is the principle behind in-row placement. Instead of chilling room air from a perimeter unit and hoping cold air reaches high-density racks before it warms up, an in-row unit sits directly between or beside the equipment it serves. Short air paths, tight thermal loops, and the ability to deploy capacity exactly where the load is: these properties make in-row cooling the precision tool of the modern high-density data hall.

Deployments that span multiple rows or support a capacity upgrade across an existing floor carry capital requirements that benefit from structured financing. We work with colocation operators, enterprise data center teams, and data center developers on in-row cooling financing from $50,000 up through large multi-row installations. The deal structures available include equipment loans, leases, and Sale-Leaseback for operators who have already purchased the equipment and want to free that capital.

In-row cooling units occupy the same footprint as a server rack, typically a standard 600mm or 800mm wide by 1200mm deep enclosure, and deploy between racks or at the end of a row. Cold air exits the front of the unit directly into the cold aisle, while the unit draws hot exhaust from the hot aisle at the rear.

Most in-row units on the market today support either direct expansion (DX) refrigerant cooling or chilled water cooling. Chilled water units connect to a building or data center chilled water loop, making them dependent on central plant capacity but also making heat rejection simpler and the unit itself more compact. DX units carry their own refrigerant circuit and can be deployed in spaces without a chilled water infrastructure, which matters for edge deployments or legacy facilities without central chilled water.

Capacity per unit typically ranges from 15kW to over 100kW depending on the model and configuration. Leading products from manufacturers like Vertiv, Schneider Electric, and Stulz span the full range of capacity requirements and are regularly financed through our programs. The modular nature of in-row cooling means capacity can scale with demand: start with the load that exists today, add units as additional racks are commissioned.

For operators running hot/cold aisle containment, in-row units integrate particularly well. Containment captures the thermal dynamics that make in-row cooling most effective by preventing cold and warm air from mixing before the unit can process it.

In-row cooling units that are already owned outright represent an asset that can be converted to working capital through a sale-leaseback transaction. The operator sells the equipment to us, receives the capital, and continues using the equipment under a lease. Nothing changes operationally. The units stay in the rack aisle, the cooling continues, and the operator has capital available for the next phase of their buildout or for other business purposes.

This is particularly useful for operators who self-funded an initial cooling deployment and now want to grow faster than cash flow allows. Rather than waiting for the prior investment to generate enough return to fund the next phase, a sale-leaseback accelerates the capital cycle. Sale-leaseback is available for well-maintained equipment with reasonable remaining useful life.

For operators carrying equipment loans with above-market rates from a prior cycle, equipment refinancing can reduce the monthly obligation and improve cash flow without changing the ownership structure of the equipment.

In-row cooling deals at or below the application-only threshold move from a completed application to funded terms in approximately one to two weeks under normal conditions. The required documentation is minimal: a one-page application, the vendor quote or purchase agreement, and three months of business bank statements. No extensive financial package required at this tier.

Larger projects, including multi-row deployments or transactions bundled with central plant infrastructure, require a standard financial review. The additional documentation includes a recent balance sheet and profit and loss statement. These deals typically close within two to three weeks from a complete documentation package.

We fund on the purchase transaction rather than requiring the equipment to be commissioned first. In-row units that have been delivered to the facility but are pending installation qualify for funding based on the delivery documentation.

In-row cooling projects move on the schedule of the capacity build, not the lender's convenience. We know that and structure transactions to close on your timeline. Submit a one-page application with the equipment details and we will have preliminary terms back to you promptly.

Can I finance in-row units that connect to an existing chilled water loop alongside units for a new loop I am also building?

Yes, both can be included in the same financing package. The key is that all equipment appears on documented invoices. The chilled water loop components, including distribution piping and the connection infrastructure, can be bundled if they are part of the project contract.

Do in-row cooling units depreciate quickly enough to make a lease more favorable than a loan?

In-row cooling equipment has a useful life of 10-15 years in well-maintained environments and does not depreciate as rapidly as IT hardware. Whether a loan or lease is more favorable depends on your tax position, accounting preferences, and whether you expect to need a technology refresh before end of useful life. We can model both structures for your specific situation.

Can I include monitoring and controls equipment in the financing?

Controls and monitoring systems that are integral to the operation of the in-row units can typically be included in the financed amount. Standalone DCIM or BMS systems are evaluated separately. If they are part of the same vendor package as the cooling equipment, inclusion is generally straightforward.

I have a mix of owned and financed in-row units. Can I add to an existing loan?

We typically structure new financing as a separate transaction rather than modifying an existing loan. If you have an existing facility with us, we look at the overall relationship when structuring new deals. If the prior deal was with a different lender, we work with the new transaction on its own merits.

What happens if an in-row unit fails and needs to be replaced under warranty? Does that affect the financing?

A warranty replacement does not affect the financing as long as the replacement is substantially equivalent to the original equipment. We typically ask to be notified if collateral is being replaced and will update the loan schedule to reflect the new serial number. The economic terms of the deal do not change.
