Installed flush into standard false ceilings, cassettes feature 360-degree circular airflow discharge patterns.
This omnidirectional air sweep eliminates dead corners and localized warm pockets, ensuring uniform temperature distribution across large open floor plans. Integrated high-lift drain pumps lift condensation water efficiently, simplifying drainage routing in finished commercial interiors.
Comprehensive Step-by-Step AC Installation Standard
Purchasing premium cooling hardware is only part of the equation; proper installation determines how efficiently and reliably a system operates over its lifespan. Authorized retail and installation partners enforce a rigorous multi-stage installation protocol executed by certified HVAC technicians:
Site Survey & Heat-Load Calculation
Technicians conduct a thorough physical inspection to evaluate room dimensions, ceiling heights, concrete thermal mass, window orientation, glass sun exposure, and occupancy loads. This calculation verifies exact tonnage requirements before equipment staging.
Refrigerant Copper Piping & Insulation
Premium, seamless VRF-grade copper tubing is laid between indoor and outdoor locations. Pipes are wrapped in heavy-duty Armaflex insulation to prevent condensation dripping inside wall cavities, and encased in protective outdoor trunking to shield against intense UV solar radiation.
Indoor & Outdoor Unit Mounting
Indoor units are mounted level on reinforced wall brackets or suspended securely in ceiling spaces using threaded steel rods and anti-vibration rubber isolators. Outdoor condensers are placed on heavy-duty anti-corrosion brackets or elevated concrete roof pads to ensure unobstructed airflow.
Nitrogen Pressure Leak Testing
Before releasing refrigerant gas, the entire copper circuit is pressurized with dry nitrogen gas at 500 PSI for 24 hours. This critical test detects microscopic flare-joint leaks, ensuring permanent gas retention under high working pressures.
Vacuum Evacuation & Digital Dehydration
Using a dual-stage digital vacuum pump, atmospheric moisture and air are extracted from the copper lines down below 500 microns. Removing internal moisture is vital to prevent acid formation and premature compressor motor burnout.
Commissioning, Airflow Tuning & Sign-Off
The system is powered up for operational commissioning. Engineers measure operating refrigerant pressures, electrical current draw (amperage), supply-air temperature drop ($\Delta T$), and louver velocity. Warranty documentation is finalized and handed to the client.

Sizing Guidelines & Heat Load Calculation Standard
Selecting exact cooling capacity is essential before purchasing equipment. Installing an undersized AC forces the unit to operate continuously without reaching target setpoints, accelerating compressor wear. Conversely, an oversized AC short-cycles—cooling the air quickly without running long enough to lower relative humidity.
While European or temperate standards allocate 1 Ton of capacity per 15 to 18 square meters, severe summer ambient temperatures in Ajman require a capacity standard of 1 Ton of Cooling per 10 Square Meters (sqm).
Heat Gain Adjustment Modifiers
- Uninsulated Roof / Top Floor Villa: Multiply base tonnage requirement by 1.20 (+20%).
- Large Unshaded West or South Glass Glazing: Multiply base tonnage requirement by 1.15 (+15%).
- High Occupancy Rooms / Commercial Kitchens: Add 0.5 Ton per additional 4–6 occupants or heat-producing commercial appliances.
| Floor Area (Square Meters / Sq Ft) | Recommended Unit Size |
|---|---|
| 10 sqm (~107 sq ft) | 1.0 Ton (12,000 BTU) |
| 15 sqm (~161 sq ft) | 1.5 Ton (18,000 BTU) |
| 20 sqm (~215 sq ft) | 2.0 Ton (24,000 BTU) |
| 25 sqm (~269 sq ft) | 2.5 Ton (30,000 BTU) |
| 30 sqm (~322 sq ft) | 3.0 Ton (36,000 BTU) |
| 40+ sqm (~430+ sq ft) | 4.0 Ton+ / Concealed Ducted Split System |
