Diagnosis & Solution
High-pressure misting pump (1000 PSI) was overheating. Drained old milky oil, replaced seals, and refilled with SAE-30 non-detergent pump oil.
Industrial Cooler Belt

Diagnosis & Solution
Rooftop cooler fan was making a loud screeching noise. Replaced the worn-out B-section V-belt and aligned the motor pulley to eliminate vibration.
Honeycomb Pad Replacement

Diagnosis & Solution
Portable coolers were not cooling effectively. Old honeycomb pads were clogged with calcium scale. Installed new 100mm thick cellulose pads.
Nozzle Replacement

Misting & Evaporative Repair
We provide expert repair and maintenance for Misting Lines, Desert Coolers, and Industrial Fans. From pump replacement to nozzle cleaning, we handle it all.
1Portable Desert Cooler
Mobile cooling units for outdoor seating, tents, and small workshops.
Technical Information
Plastic body with large water tank and honeycomb cooling pads. Uses natural evaporation to cool air without gas.
Working Principle
A submersible pump wets the honeycomb pads, and a fan pulls hot air through them, instantly reducing temperature.
Maintenance & Repair Services
Hygiene
- Tank & Pad sanitization
- Sludge removal
- Odor elimination treatment
Mechanical
- Submersible pump replacement
- Castor wheel repair
- Fan blade balancing
2Industrial Ducted Cooler
Heavy-duty rooftop units for factories, warehouses, and open kitchens.
Technical Information
Metal body installed on rooftops. Connects to ductwork. Uses heavy-duty belts, pulleys, and large blower fans.
Working Principle
Delivers massive CFM of cooled fresh air. Requires precise float valve adjustment to maintain water levels.
Maintenance & Repair Services
Drive System
- Fan belt tensioning & alignment
- Motor bearing lubrication
- Pulley alignment
Water System
- Float valve adjustment
- Water distribution pipe clean
- Leak proofing
3High-Pressure Misting Line
Luxury outdoor cooling for pergolas, restaurants, and villas.
Technical Information
Uses a high-pressure pump (1000 PSI) and stainless steel pipes with ruby-orifice nozzles.
Working Principle
Water is pressurized to create ultra-fine mist (flash evaporation) that cools the air without wetting surfaces.
Maintenance & Repair Services
Nozzle Care
- Nozzle chemical descaling
- Anti-drip valve check
- Orifice cleaning
High Pressure
- Pump oil change (500 hrs)
- SS Pipe leakage repair
- Pressure regulation
4Misting Fans
Versatile spot cooling for events, poolsides, and patios.
Technical Information
Industrial fan integrated with a misting ring or localized water tank. Mobile and effective.
Working Principle
Combines high-velocity airflow with mist to provide wind-chill cooling in specific zones.
Maintenance & Repair Services
Fan Repair
- Fan motor rewinding
- Oscillation gear fix
- Guard cleaning
Mist System
- Mist ring cleaning
- Nozzle unclogging
- Feed tube replacement
5Pumps & Filtration System
The heart of evaporative cooling. Clean water ensures longevity.
Technical Information
Critical Issues: 'Scale Buildup' (Salt deposits on pads/nozzles), 'Pump Burnout' (Low water level).
Working Principle
Filtration removes sediment and calcium before water reaches the sensitive pump and nozzles.
Maintenance & Repair Services
Filtration
- Sediment filter replacement
- Water softener installation
- Scale inhibitor dosing
Pump Works
- High-pressure pump seal fix
- Solenoid valve replacement
- Oil seal change
Evaporative System Care
Blocked nozzles and dirty tanks reduce cooling efficiency and breed bacteria. Our focus is on Deep Sanitization & Descaling.
Deep Tank & Pad Sanitization
Stagnant water causes bad smells and bacteria (Legionella). We drain the tank, scrub the sludge, and chemical-wash honeycomb pads.
Misting Nozzle Descaling
Blocked nozzles stop misting. We remove and soak nozzles in acidic descaling solution to dissolve calcium and salt deposits.
Annual Maintenance Contract (AMC)
Ensure your outdoor area is ready for summer. Includes pump oil change, belt adjustment, and pre-season cleaning.

AFTERRestaurant Terrace - Misting Failure
Problem: Nozzles dripping water instead of misting. Customers getting wet due to calcium buildup inside nozzles.
Solution: Descaled all 40 nozzles in acid bath, replaced the sediment filter, and serviced the high-pressure pump valves.
Result: Perfect fine mist restored, outdoor seating usable again.
BEFOREAFTERWarehouse - Industrial Cooler Noise
Problem: Loud screeching noise from rooftop unit. Loose fan belt and dry motor bearings.
Solution: Tightened V-belt tension, aligned the pulley, and greased motor bearings.
Result: Cooler running silently with improved airflow.

Job Card #2024
Generated on 15 Nov 2024
Technician Notes:
Misting pump oil changed. 15 nozzles descaled. Filter replaced.
System Lifespan & Care
Portable Coolers
Typical lifespan: 3-5 years. Regular tank cleaning prevents bacterial growth and pump failure.
Misting Pumps
Typical lifespan: 5-7 years. Oil changes every 500 hours are critical for high-pressure systems.
Common Issues
Bad smells (bacteria), blocked nozzles (salt buildup), and loud pump noise are common issues we solve.

We have large Industrial Coolers for our warehouse. UNITECH adjusted the belts and greased the bearings. The screeching noise is gone and airflow is much better.
What Our Clients Say
"Our outdoor misting system stopped working right before the weekend. UNITECH came, cleaned the nozzles, and changed the oil. Saved our Friday brunch!"
Mr. Thomas

Frequently Asked Questions
Do you serve commercial buildings?
Yes, we specialize in Rooftop Package Units for malls, offices, and warehouses.
Is your work guaranteed?
Yes, we provide a 1-month warranty on service and up to 1-year warranty on replaced compressors.
How quickly can you arrive?
For emergencies in Dubai, our target arrival time is under 90 minutes.
Why is chemical cleaning necessary?
Water alone cannot remove the salt and dust cemented onto the aluminum fins. Chemical foam lifts this grime to restore heat exchange efficiency.
