City Mall, Amman case study
Catalytic technology eliminated the need for softeners and chemicals at Jordan’s largest shopping mall.
Client: City Mall, Amman
Region: Jordan
Application: Domestic hot water and cooling water systems
Sector: Commercial / Retail
City Mall, Jordan’s largest retail complex, was constructed in 2005. During design, the engineering consultants specified traditional softeners and chemical dosing to protect the hot water, air conditioning, and cold water systems from scale. This approach required additional pipework, chemical storage space, and daily maintenance.
The challenge
Prevent scale build-up across domestic hot water, cold water, and HVAC systems
Softeners and chemical dosing systems added significant capital cost, space requirements, and running costs
Daily maintenance and chemical handling raised health and safety concerns
Backwashing softeners would waste water and energy
The solution
Fluid Dynamics proposed catalytic Colloid-a-tron (CAT) units as a non-chemical alternative. The design eliminated the need for softeners and dosing systems, saving space, installation cost, and ongoing maintenance.
Installation
1 × unit replacing the softener system
2 × units on the hot water supply
2 × units on each calorifier
1 × unit on the cold water supply serving taps and urinals
1 × unit on the air conditioning circuit
Results
System protected from scale without salt or chemicals
Substantial savings in equipment, chemicals, labour, and water use
No maintenance requirements or chemical handling risks
Energy efficiency improved with scale-free operation
Since 2005, the mall has saved tens of thousands of dollars in running costs
