AC & Refrigeration for Agriculture

Refrigeration and cooling systems are core infrastructure in modern agriculture — not just for preservation, but for productivity, food safety, and training students in real industry practices.

Here's how they fit into an agriculture vocational department:

Post-Harvest Storage & Food Preservation

  • Fresh produce continues to respire after harvest.

  • Cooling slows biochemical degradation and microbial growth.

Why it matters:

  • Extends shelf life of fruits, vegetables, herbs, and flowers

  • Maintains quality grade (color, firmness, nutrient content)

  • Reduces post-harvest losses — a major economic factor

  • Teaches students about the cold chain and temperature management

Dairy, Meat & Animal Production Systems

Typical applications in training farms:

  • Bulk milk cooling tanks (rapidly drop milk to ~4 °C)

  • Egg storage refrigeration

  • Meat or fish processing cold rooms

  • Veterinary sample storage

DMH offers a range of cooling solutions, from a standard fridge up to cooling tanks and walk-in cooling rooms.
