CVF-1500W-3P Vegetable Vacuum Pre-Cooler — 3-Pallet Water-Cooled
CVF-1500W-3P vegetable vacuum pre-cooler handles 1500kg per batch in 15-30 minutes with 1-2% weight loss. Water-cooled with cooling tower, 95-137kW cooling capacity. For mid-size vegetable bases and wholesale markets.
Vacuum pre-cooling makes surface moisture evaporate at reduced pressure, pulling field heat out of produce fast. The CVF-1500W-3P is a 3-pallet standard model handling 1500kg per batch, cooling produce to 0–10°C in 15–30 minutes with 1–2% weight loss. The water-cooled configuration suits mid-size vegetable bases and wholesale-market support.
Overview
The CVF-1500W-3P is a 3-pallet water-cooled vegetable vacuum pre-cooler for mid-size bases and wholesale-market support. The chamber is about 12m³ (L4000×W1500×H2000mm), holding 3 standard pallets. A Bitzer compressor + Leybold vacuum pump delivers 95kW+ cooling capacity. The complete machine includes the mounting frame, vacuum chamber, vacuum pump, and refrigeration system.
Three selling points:
- Standard 3-pallet size, 1500kg/batch — right for mid-size bases
- 15–30 minute rapid pre-cooling with 1–2% weight loss
- Water-cooled + tower — high refrigeration efficiency in hot regions

Product Advantages
1. Standard 3-Pallet Size
Fits standard pallets, easy loading — one machine covers a mid-size base’s daily volume.
2. Rapid Pre-Cooling
15–30 minutes from field temperature to 0–10°C — over 10× faster than cold-room natural cooling.
3. Low Weight Loss
1–2% weight loss vs 3–5% in open-air cooling — better freshness and appearance.
4. Water-Cooled Efficiency
Water-cooled + tower delivers high refrigeration efficiency in hot regions, with 95–137kW margin.

FAQ
Q1: How much per batch? 1500kg per batch (3 pallets). Leafy vegetables pre-cool in 15–30 minutes; 7–15 tonnes per day depending on batches.
Q2: What is the weight loss? 1–2%. Lower than open-air cooling — better appearance and less spoilage.
Q3: Is a cooling tower required? Yes. Standard fit is a water-cooled condenser + tower; confirm water supply. An evaporative-condenser option suits water-scarce regions.
Q4: Does it need defrosting? No. Pre-cooling cycles are 15–30 minutes — the vapor condenser does not need defrosting.
Q5: What warranty and response time? Full-machine warranty 1 year; major components follow brand standards. Domestic fault response within 24 hours.
