Engineering Standards

We integrate premium thermal and mechanical components to secure your milk quality against power outages and bacterial spikes.

✓ AISI 304 Stainless
✓ Direct Expansion
✓ CFC-Free Polyurethane

Thermal Performance

60-80mm PU Insulation

A solid polyurethane foam layer ensures exceptional thermal retention. Temperature fluctuates less than 1°C over a 12-hour power outage, securing your yield.

Milk Quality Protection

36 RPM Gentle Agitation

Engineered low-speed agitators ensure completely even cooling dispersion without breaking fat globules, churning butter, or causing foaming in the tank.

Automated Hygiene

360° CIP Spray System

Integrated rotational spray balls paired with programmable automated wash cycles remove human error, guaranteeing pristine internal hygiene every wash.

Total Cost of Ownership (TCO) & Sizing Guide

Milk cooling represents a significant portion of farm energy usage. Proper compressor pairing and tank sizing are critical for protecting your bottom line.

1. Sizing Your Tank Capacity

Do not size your tank strictly on current daily yield. Commercial standard practice dictates sizing the tank to hold a minimum of 3 days of maximum projected milk production (especially if collection trucks face weather or logistical delays).

For example, if your herd produces 2,000 liters daily, a minimum 6,000L (6-Ton) Horizontal tank is recommended to prevent forced dumping during transport disruptions.

2. Compressor Power & Energy Savings (OpEx)

An undersized compressor runs continuously, destroying efficiency and shortening its lifespan. An oversized unit causes flash freezing, damaging milk structure. NexAgri engineers match highly reliable refrigeration units (such as Copeland scroll compressors) exactly to your tank's evaporator plate surface area.

Coupled with our high-density polyurethane insulation, the compressor only triggers periodically to maintain 4°C, significantly reducing your monthly electrical expenditure.

3. Milk Quality & Premium Pricing

Milk leaves the udder at approximately 35°C—the perfect environment for rapid bacterial multiplication. By utilizing NexAgri direct expansion plates, milk drops to the critical 4°C threshold in under 2.5 hours. This immediate stabilization ensures you continually meet stringent dairy processor requirements, securing top-tier payment premiums for low bacterial counts.

Technical Frequently Asked Questions

Expert technical answers to help you plan your commercial cooling setup.

How do I choose the right bulk milk cooling tank size?
Industry best practice is to calculate your maximum daily yield during peak lactation and multiply it by your collection frequency, plus a 20% safety margin. If the milk truck collects every 48 hours, and you produce 1,000L a day, you need a minimum of a 2,500L to 3,000L tank to prevent forced dumping.
What is the difference between vertical and horizontal cooling tanks?
Vertical tanks (up to 3,000L) are designed for small family farms where milk room floor space is restricted. They utilize gravity for complete drainage. Horizontal tanks (1,000L to 30,000L) are for commercial dairies. They offer a larger evaporator surface area for faster cooling and maintain a stable, low center of gravity for massive volumes.
Does the tank come with the refrigeration compressor?
Yes. We supply a complete turnkey cooling solution. The tank is shipped with an expertly matched refrigeration unit (using trusted brands like Copeland or Maneurop) fully calibrated to the tank's exact evaporation surface area for maximum energy efficiency.
Can the cooling tank work with a generator during power outages?
Absolutely. The systems can run on a backup generator providing stable 3-Phase power (typically 380V/50Hz). Moreover, our 60-80mm CFC-Free polyurethane insulation ensures that even if the generator fails, milk temperature rises less than 1°C over a 12-hour period, protecting your product.
How much electricity does a direct expansion milk cooling tank consume?
Energy consumption strictly depends on tank capacity and incoming milk temperature. However, because we engineer our compressor power to perfectly match the evaporator plate surface, our tanks meet the rigorous ISO 5708 energy efficiency standard, ensuring the compressor runs only when necessary and minimizing OpEx.
What maintenance is required for a milk cooling system?
Routine maintenance is minimal. Operators must ensure the condenser fins are kept clean from dust for efficient heat exchange, check refrigerant levels annually, and ensure the automated CIP (Clean-In-Place) system is supplied with correct acid/alkaline detergent ratios. The agitator motor and stainless steel body are designed for decades of zero-maintenance use.
