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
