Portable Spot Cooler
Why Localized Cooling Beats Building‑Wide HVAC
Precision Where You Need It
Traditional rooftop units are designed for whole‑building comfort, but a commercial spot cooler attacks the exact hotspot that is disrupting workflow. By rolling a portable unit next to a bottleneck machine or heat‑soaked server rack, you deliver chilled air exactly where temperature spikes are costing you money.
Built‑In Dehumidification
Every refrigerated spot cooler is also a portable AC with dehumidifier. Removing latent moisture protects electronics, adhesives, and coatings in high‑humidity regions while reducing heat stress on people and equipment.
Faster Deployment, Lower Capital Spend
Some portable units ship ready to work without needing permits, crane lifts, or chilled‑water tie‑ins. Rent for a weekend outage, rent for seasonal demand, or purchase outright for year‑round insurance against heat‑related downtime.
Step‑By‑Step Sizing Checklist
1. Calculate the Heat Load
Multiply square footage by ceiling height for cubic feet. Add in sensible loads, such as 400 BTU/hr per person, the wattage of lighting converted to BTU, plus machinery output. A simple rule: one ton of cooling (12,000 BTU) covers roughly 400 sq ft of lightly loaded space or one high‑temperature machine station.
2. Verify Electrical Service
- 115 V single‑phase limits you to about one ton per receptacle.
- 208–230 V single‑phase supports 2‑ to 3‑ton units.
- 208–230 V or 460 V three‑phase opens the door to 5‑ to 7‑ton giants.
3. Plan the Heat‑Rejection Path
Air‑cooled spot coolers exhaust hot air through flex duct. Vent the discharge into a plenum, out a window, or into a non‑critical area. If no vent path exists, explore water cooled spot coolers that reject heat via a water line.
4. Think Mobility and Footprint
Closets demand compact frames and swivel nozzles; production floors value steel chassis, locking casters, and forklift pockets.
5. Handle Condensate Smartly
Choose between an internal tank, gravity drain, or pump‑out hose. A flooded floor pan equals downtime.
Airrex: Industrial DNA in Every Model
Airrex spot coolers are engineered for 24/7 duty in dusty, high‑vibration environments. Two models bracket the capacity range most facilities require.
Airrex HSC‑12L is a One‑Ton Workhorse
Key Specifications
- Cooling Capacity: 12,000 BTU/hr (1 ton)
- Power: 115 V, 15 A (standard wall outlet)
- Airflow: Up to 390 CFM through dual directional nozzles
- Condensate Management: Integrated pump with 20 ft lift
- Noise: ~60 dB and is quiet enough for labs and offices
Ideal Applications
- Server & IDF Closets: Dense electronics can spike internal temps by 20 °F. Aim the nozzles at rack intakes and prevent thermal throttling.
- Laboratories & Print Farms: Protect temperature‑sensitive processes in retrofitted office space.
- Retail Kiosks & POS Zones: Keep delicate point‑of‑sale hardware alive during summer heat waves.
- Emergency Response: Roll in overnight when a rooftop unit fails and safeguard irreplaceable equipment.
Airrex HSC‑70P is Seven Tons of Industrial Muscle
Key Specifications
- Cooling Capacity: 84,000 BTU/hr (7 tons)
- Power: 208–230 V, three‑phase, 50 A
- Airflow: Up to 3,000 CFM through two 16‑inch supply ducts
- Mobility: Heavy‑duty swivel casters plus forklift pockets
- Noise: 68 to 70 dB, which is conversation level despite massive output
Where It Shines
- Large Production Lines: Flood cool a 2,500–3,000 sq ft bottling or packaging area while maintenance teams work on permanent HVAC.
- Hospital & Lab Outages: Provide temporary cooling for MRI suites or clean rooms where downtime costs skyrocket by the minute.
- Aircraft Hangars & Heavy‑Equipment Bays: Push chilled air up to mezzanine‑level work decks with high static pressure.
- Event & Film Sets: Quietly cool backstage areas or hospitality tents without diesel chillers.
Matching Capacity to Risk for a Narrative Comparison
A telecom closet might overheat with just 1 to 2 kW of equipment. This is where the nimble, plug‑and‑play HSC‑12L delivers more than enough capacity while fitting through a 32‑inch doorway. In contrast, a seven‑day plant outage on a 24/7 packaging line can burn six figures in lost production. The HSC‑70P steps in with the airflow and static pressure to blanket the entire line, keeping operators safe and product on spec. Choosing the right tonnage avoids paying seven‑ton rental rates when a one‑ton solution would have sufficed. This also prevents the reverse disaster of under sizing.
Maintenance That Takes Two Minutes a Week
- Vacuum Filters Weekly in dusty environments; swap monthly elsewhere.
- Blow Out Condenser Coils Quarterly to maintain efficiency and low head pressure.
- Inspect Drain Lines Monthly as standing water breeds bacteria and triggers float switches.
- Check Electrical Lugs Semi‑Annually on three‑phase units; vibration loosens terminals over time.
- Lock Casters Before Each Shift for safety first on busy production floors.
Applications That Benefit Most from Portable Spot Coolers
Data & Telecom
Direct chilled air at server intakes to avoid thermal shutdowns.
Manufacturing & Fabrication
Keep hydraulic power units, CNC cabinets, and injection‑molder barrels within temperature spec.
Warehousing & Fulfillment
Cool pick aisles where employees work while allowing upper pallet racks to run warmer for energy savings.
Food & Beverage
Stabilize ambient temperature and humidity around filling lines so labels stick and sugars don’t caramelize on equipment.
Events & Temporary Structures
Maintain a 72 °F VIP lounge inside a tent when asphalt outside reads 105 °F, and no diesel chiller is required.
