DURUB WATER SOLUTIONS – Cooling & Circulation Engineering Division
1. Introduction
In UAE poultry farms, water temperature is a silent factor that affects productivity more than most owners realize.
When tank water reaches 35–45°C in summer (which is normal here), birds immediately suffer from:
- reduced water intake
- stress and dehydration
- weaker immunity
- slow growth
- higher mortality
- lower feed conversion rate (FCR)
- poor egg production
Cooling the tank is not a luxury — it is essential for maintaining bird health and farm profitability.
This report explains the engineering requirements for designing an effective tank cooling system for UAE farms.

2. How Hot Water Impacts Bird Health
1. Reduced Drinking Water Intake
Birds naturally avoid hot water; even a 3–5°C increase makes them consume less.
Water intake ↓ → Feed intake ↓ → Weight gain ↓
2. Increased Heat Stress
Hot water does not cool the bird’s internal temperature, causing constant heat stress.
3. Lower Growth Rate
Broilers grow slower when water exceeds 30°C.
4. Higher Mortality
Heat waves combined with hot drinking water increase mortality — especially in closed farms.
5. Poor Egg Production in Layers
Temperature affects shell quality, yolk color, and feed intake.

3. Engineering Challenges in UAE Climate
UAE farms face unique conditions:
Outdoor tank temperature can exceed 50°C
High ambient temperature
Long piping networks (60–120 meters)
Poor insulation in many older farms
Continuous demand from birds
This means the cooling load must be calculated with higher accuracy.

4. Cooling Load Calculation (The DURUB Method)
When cooling a 500-gallon (≈ 1,890 L) tank, DURUB engineers consider:
✔ Initial water temperature (up to 45°C)
✔ Target temperature (18–22°C ideal for birds)
✔ Distance between chiller and tank (2–120 meters)
✔ Pipe heat gain along the farm
✔ Pump circulation speed
✔ Simultaneous water usage
✔ Outdoor heat + tank exposure

5. Why a Safety Factor Is Necessary
- Cooling systems in farms face unpredictable loads:
- sudden peak drinking by birds
- sudden temperature spikes
- heat transfer through long pipe runs
- additional water entering tank during daytime
So
DURUB applies a 30% Design Safety Factor (DSF) for accurate cooling performance in UAE summer.
This ensures continuous stable water temperature even at peak demand.

6. Recommended Cooling System Setup
1. Chiller Unit
Capacity depends on tank volume + pipe distance:
2–3 Ton Chiller → small farms
3–5 Ton Chiller → medium farms
5+ Ton Chiller → large farms or long pipe runs
2. Circulation Pump
Must match the chiller flow rate.
Incorrect pump size = ineffective cooling.
3. Insulated Tank (Optional but recommended)
Even simple insulation reduces heat gain by 40–60%.
4. Return Loop Piping
Flow must be continuous to avoid temperature layering.
5. Control Panel
Includes:
digital thermostat
safety cut-off
circulation control
alarm indication (optional)
6. Flow Balance & Pressure Management
Correct balancing ensures equal cooling across all drinker lines.

7. Common Mistakes in Farm Cooling Systems
Many farms fail because of:
using domestic chillers (not for farms)
undersized circulation pump
long pipe run without compensation
no insulation
wrong thermostat placement
cheap piping that absorbs heat
tank placed directly under sunlight
DURUB’s engineering eliminates these issues completely.
