Project Summary

IEC UAE designed and executed a combined fresh air ventilation and cooling system for RAK Porcelain's production and warehouse facility in Ras Al Khaimah. The scope brought together a Fresh Air Handling Unit (FAHU) with heat recovery and a VRF air-conditioning system — delivering continuous filtered fresh air, controlled extraction of odour-laden air, stable temperature, and managed humidity across the working areas.

Client Overview

RAK Porcelain is one of the world's leading manufacturers of professional-grade porcelain tableware for the international HORECA industry, operating a large-scale production and warehousing facility in Ras Al Khaimah. Their operation demands consistent indoor conditions — clean air for staff, controlled humidity for product decoration and printing quality, and stable temperatures across large open production and storage volumes.

Scope of Work IEC UAE Delivered Complete Ventilation & HVAC Execution, Including

IEC UAE handled the full mechanical package from design coordination through commissioning:

  • ✅ Supply and installation of FAHU with integrated heat recovery section
  • ✅ Fresh air intake, filtration and treatment system
  • ✅ Extraction system for removal of stale and odour-laden air
  • ✅ Supply and installation of VRF indoor and outdoor units
  • ✅ Hard-drawn copper refrigerant piping with closed-cell insulation
  • ✅ Ducting, air distribution and diffuser layout across production and storage areas
  • ✅ Airflow balancing to maintain positive pressure and consistent air change rates
  • ✅ Complete testing, commissioning and performance verification
  • ✅ Execution phased around live production schedules with minimal downtime

Technologies & Equipment Used

  • Fresh Air Handling Unit (FAHU)
  • Heat Recovery Unit / Energy Recovery Section
  • VRF Indoor Units
  • VRF Outdoor Units
  • Exhaust Air System
  • Hard-Drawn Copper Refrigerant Piping
  • Insulated Ducting & Air Distribution Network

Project Challenges

  • ⚠️ Persistent odour build-up inside enclosed production and warehouse areas with insufficient air change
  • ⚠️ No existing air-conditioning across large open-volume working spaces
  • ⚠️ Uncontrolled humidity affecting the consistency and quality of porcelain decoration and printing
  • ⚠️ High cooling load associated with continuously treating large volumes of hot outdoor fresh air
  • ⚠️ Requirement to execute installation without interrupting ongoing production and dispatch operations

Our Solution

IEC UAE engineered an integrated fresh air and cooling strategy rather than treating ventilation and air-conditioning as separate systems.

Our approach included:

  • ⚙️ FAHU drawing filtered outdoor air into the facility, treated for both temperature and moisture content before delivery
  • ⚙️ Dedicated extraction system removing stale, odour-laden air, with the space held at slight positive pressure so odours cannot re-circulate or migrate between areas
  • ⚙️ Heat recovery section using the outgoing exhaust air to pre-cool incoming fresh air, significantly reducing the cooling load on the system
  • ⚙️ VRF system providing zone-level temperature control across production, decoration and storage areas
  • ⚙️ Humidity managed at the FAHU stage to support consistent porcelain printing and decoration quality
  • ⚙️ Full commissioning and airflow balancing to verify air change rates and cooling performance across every zone

Results / Outcome 🏆

Clean, Odour-Free Air

Continuous fresh air supply with controlled extraction eliminated odour build-up across production and warehouse areas

Controlled Humidity

Stable moisture levels supporting consistent porcelain decoration and printing quality

Reduced Power Consumption

Heat recovery lowered the cooling load on incoming fresh air, cutting operational energy cost

Improved Working Environment

Comfortable, consistently cooled conditions for staff across large open production and storage volumes
