Mexico: Tropical Climate Vacuum Pre-Cooling Adaptation — CVF-3000-6P
A Mexican mixed produce facility uses a CVF-3000-6P vacuum pre-cooler with oversized evaporative condenser (15%) and triple Leybold pumps for consistent year-round cooling in tropical conditions.
The Challenge
Tropical Mexico means high ambient temperatures and high condenser loads. Without sufficient condenser capacity, the refrigeration system cannot maintain the –10 to –15°C evaporator temperature needed for the vapour trap. The client needed consistent cooling cycle times year-round, even in the hottest summer months.
The Solution
We delivered a CVF-3000-6P (6-pallet) vacuum pre-cooler with tropical-climate adaptations:
| Parameter | Value |
|---|---|
| Model | CVF-3000-6P (6 pallet) |
| Product | Mixed fruits and vegetables |
| Capacity | ~3,000 kg per batch |
| Compressor | BITZER CSH8553 |
| Vacuum pumps | 3× Leybold SV300 |
| Expansion valves | Danfoss TES55 |
| Condenser | Evaporative, oversized by 15% (YFL-495) |
| Power | 440V/60Hz/3P |
| Status | ✅ Running since 2021 |
The evaporative condenser was oversized by 15% to handle the higher heat rejection load. The Danfoss TES55 expansion valves were selected to handle the wider pressure differential.
Results
- Consistent cooling cycle times year-round
- No performance degradation during hottest summer months
- Reliable operation since installation in 2021
Key Takeaway
Hot-climate installations need condenser safety margin. 15–20% oversizing is cheap insurance against high-ambient performance loss.
