Site Survey & Infrastructure Checklist — 5 Must-Checks Before Shipping Export Projects

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.
