Precision cooling keeps data centres, server rooms, and computer rooms within the narrow temperature and humidity band that IT and communications equipment needs to run reliably. Unlike comfort air conditioning, which is designed for people, precision cooling runs continuously, controls humidity as well as temperature, and is sized to the heat load of the equipment in the room. Get it wrong and you risk thermal shutdowns, shortened hardware life, and unplanned downtime.
NPS designs, supplies, installs, and maintains precision cooling from STULZ and Vertiv Liebert, two of the world’s leading names in computer room cooling. From a single server cupboard to a full data hall, NPS matches the cooling type and capacity to your load, your room, and your redundancy requirements.
CRAC Units and Precision Cooling Types
Precision cooling comes in several forms, each suited to a different room size and heat density. NPS supplies the full range:
- CRAC units (computer room air conditioners): Floor-standing direct-expansion units that cool the whole room, the traditional workhorse of computer room and data centre cooling.
- CRAH units (computer room air handlers): Chilled-water room cooling for larger facilities served by a central plant.
- In-row cooling: Units placed between the racks, close-coupled to high-density loads for efficient, targeted heat removal.
- Room-based and perimeter cooling: Downflow and upflow units around the room perimeter, feeding a raised floor or overhead plenum.
- Close control and free-cooling units: Tight temperature and humidity control, with free-cooling economisers that cut energy use in cooler weather.
Precision Cooling by Brand
- STULZ: A precision-cooling specialist whose CyberAir CRAC and CyberRow in-row ranges cover data centre and computer room cooling from small rooms to large halls.
- Vertiv Liebert: The Liebert PEX room-based units and Liebert CRV in-row units provide flexible cooling for data centres and server rooms.
Precision Cooling Across Your Facility
Cooling works best when it is planned with the equipment it protects:
- UPS systems: Cooling and UPS are the two continuous loads in any critical room, sized and maintained together.
- Racks and cabinets: Rack layout and containment determine how effectively CRAC and in-row cooling remove heat.
- Power management and monitoring: Temperature and humidity sensors tie cooling performance into the same platform that watches your power.
Where Precision Cooling Matters
NPS delivers precision cooling across the sectors that depend on continuous, controlled environments:
- Government: Council data centres and public infrastructure where service delivery depends on uptime.
- Healthcare: Hospital data rooms and medical imaging suites where equipment and patient services rely on stable conditions.
- Communications: Exchanges, data halls, and remote sites where cooling failure quickly becomes an outage.
- Manufacturing: Control rooms and on-site server rooms in environments that are often hot, dusty, or humid.
- Mining: Remote-site communications and control rooms that must stay cool far from support.
Precision Cooling Services from NPS
NPS provides the services that keep precision cooling reliable over its whole life:
- Turnkey Power Solutions: Heat-load assessment, cooling design, and integration with your UPS, racks, and power distribution as a single project.
- Installation and Commissioning: Cooling installed and commissioned by qualified technicians and tested against the room’s design heat load.
- Maintenance and service: Scheduled maintenance of STULZ and Vertiv Liebert units, including filters, refrigerant, and controls, so cooling capacity is there when the room needs it.
