A 3-ton compressor can't sit on a standard floor slab. A 50 m³/h cooling tower needs pH 7.0–8.5 water. This is the site survey checklist we send every overseas customer before shipping.
1. Floor Load Capacity
A CVF-3000-6P weighs ~6,800 kg. The compressor module creates 833 kg/m² point load — standard factory floor design is 500–750 kg/m².
| Parameter | Pass | Warning |
|---|---|---|
| Floor thickness | ≥150mm reinforced | <120mm |
| Point load | ≥1,000 kg/m² | <750 kg/m² |
| Levelness | ±5mm/3m | >10mm deviation |
| Expansion joint | ≥500mm from joint | Spanning joint |
2. Power Supply
Peak current during vacuum pull-down (first 3-5 min) reaches 2.5x running current.
| Parameter | Pass | Warning |
|---|---|---|
| Voltage (loaded) | Rated ±5% | >±10% |
| Main breaker | ≥3x running current | ≤2x |
| Cable size | ≥16mm² for 32A@30m | <10mm² |
| Ground resistance | ≤4Ω | >10Ω |
3. Cooling Water
| Parameter | Pass | Warning |
|---|---|---|
| Flow rate | ≥1.5x condenser rated | <1.0x |
| Pressure | 2-4 bar | <1.5 bar |
| pH | 7.0–8.5 | <6.5 or >9.0 |
| Hardness | ≤100 ppm | >200 ppm |
4. Installation Space
| Model | Height | Door Swing | Service Clearance |
|---|---|---|---|
| CVF-1000-2P | 2.2m | 1.0m | Rear 1.0m, side 0.8m |
| CVF-3000-6P | 2.6m | 1.5m | Rear 1.2m, side 1.0m |
| CVF-4500-6P | 2.8m | 1.8m | Rear 1.5m, side 1.2m |
5. Ambient Conditions
Peak summer temp, winter low, dust level, altitude, ventilation — all affect equipment selection.
