Knowing how to prepare your facility for temporary cooling installation ensures seamless equipment hookup, prevents costly crane demurrage charges, and restores comfortable indoor temperatures without delays. Whether you are installing a 150 TR chiller for a commercial complex or multiple 25 TR packaged AC units for an event, proper site readiness is critical.
The 5-Step Facility Preparation Protocol
1. Designate a Level, Ventilated Outdoor Equipment Pad
Industrial chillers and packaged AC units require outdoor placement with unrestricted vertical airflow for heat rejection:
- Provide a solid, level concrete pad or compacted gravel base capable of supporting 5 to 12 metric tons.
- Maintain a minimum of 2.0 meters of clear perimeter space around condenser coil air intakes.
- Ensure a minimum vertical clearance of 4.5 meters above condenser fan discharge to prevent thermal air recirculation.
2. Verify Mechanical Water Tie-In Locations (Chiller Installations)
For temporary chiller integration into existing hydronic building loops, verify the following:
- Locate supply and return chilled water headers; ensure isolation valves close completely without weeping.
- Confirm flange or grooved coupling (Victaulic) sizes (typically 3-inch, 4-inch, or 6-inch diameter).
- Install manual air bleed vents at the highest piping elevation to eliminate airlocks during water refilling.
3. Electrical Switchgear & Breaker Audit
Review your building's electrical capacity before the equipment arrives:
- Confirm 400V 3-phase 50Hz electrical supply with a dedicated molded case circuit breaker (MCCB) matched to the chiller's Full Load Amperage (FLA).
- Ensure the breaker features adjustable magnetic trip thresholds to absorb initial compressor inrush currents.
- If building power is unavailable or constrained, coordinate an auxiliary 500 kVA generator for self-contained power.
4. Plan Clean Cable and Hose Pathways
Measure exact distances from the outdoor chiller location to the mechanical tie-in valves and main switchboard:
- Route flexible water hoses along non-pedestrian corridors, utilizing protective heavy-duty hose bridges across active vehicle lanes.
- Run power cables through protected cable ramps to prevent physical crushing by delivery trucks and forklifts.
5. Water Supply for Initial Loop Charging
Have a pressurized municipal or treated water source available to fill the temporary flexible hoses and bleed trapped air. Ensure water treatment chemical inhibitors are on site to protect against internal pipe scale and microbial growth.

Frequently Asked Questions
How much water pressure is required in the building chilled water loop?
Standard commercial chilled water loops operate at 2.5 to 4.5 bar static pressure. Our temporary pumps are calibrated to match your building's expansion tank setpoints.
Can temporary flexible water hoses freeze in winter?
No. Chilled water loops in the UAE operate between 6°C and 12°C, well above freezing point. All external hoses feature closed-cell elastomeric insulation to prevent ambient thermal gain and condensation sweating.
Who handles municipal permits for outdoor equipment placement?
Rental Power UAE assists facility teams with municipal and Civil Defence notifications for equipment placed in public-facing or commercial parking bays across Dubai and Abu Dhabi.
