In a data center’s cold aisle, between rows of server racks, an engineer kneels at the open front panel of a perimeter cooling unit.

For HVAC service firms that maintain data center cooling

Cooling that can’t stop, maintained one unit at a time.

In a data hall the cooling never gets a day off. Frigalto is built for the firms that maintain it — CRAH and CRAC units, chillers, cooling towers — planning every unit out of service and back, logging each one’s inspection and refrigerant, and showing the operator exactly what was touched and when.

What data center clients judge you on

Four things a data center asks of its cooling maintenance firm.

  1. Cooling stays on while you work

    You never get the whole hall. Each unit comes out of service on its own, inside the client’s change window, while the others carry the load — and goes back before the next one comes out.

    On the recordEach unit’s time out of service and back in service, in order.

  2. Change control asks first

    Before a panel opens, the operator wants to know what you will touch, in what order and when. After, they want to see that it happened that way.

    On the recordThe round planned unit by unit, and the record of what was done against the plan.

  3. Their own customers ask them

    An operator answers to the businesses in its halls. When they ask how the cooling is maintained, the operator reaches for your record.

    On the recordAn Uptime Report for the hall, compiled from the inspections, findings and unit status.

  4. Behind the hall, the plant

    The perimeter units are only the front of it. Chillers, pumps and cooling towers sit behind them, and DX units carry refrigerant circuits of their own.

    On the recordEvery chiller, tower and unit in the registry, with a Refrigerant Record per circuit.

One unit out

One unit out, the hall still cold.

A monthly round in Northfield’s hall 2. One perimeter unit at a time is taken out of service, inspected to its protocol and put back, while the rest carry the hall. Only then does the next one come out.

What Frigalto is built to do

For every hall you look after.

  • Keep every perimeter unit, chiller, pump and cooling tower in one registry, hall by hall
  • Plan each round unit by unit, and record each unit out of service and back
  • Inspect each to the protocol for its type, with photos of what was found
  • Log every refrigerant entry against the circuit it belongs to
  • Compile the hall’s Uptime Report, with a summary you edit, and send it when you choose

Frigalto keeps the maintenance record. It does not read live data from the building management system.

Where your work sits in a data center

From the hall to the roof.

Each part of the cooling chain is a place in the record, with its own units.

  1. Data halls and perimeter units
  2. Cold and hot aisles
  3. Chiller plant rooms
  4. Pump rooms
  5. Cooling towers and dry coolers
  6. UPS and battery rooms

Frigalto records support refrigerant and maintenance record-keeping obligations. Frigalto does not issue EPA-608 or F-Gas certifications and does not verify operator-entered credentials.
