In the prime location of Makati, Philippines, the Social Security System (SSS) Makati Building once struggled with the "three highs" dilemma caused by its traditional central air conditioning system: soaring electricity bills, constant noise complaints, and frequent equipment maintenance. The challenges faced by this landmark building epitomize the cooling difficulties of tropical office towers in Southeast Asia - where the scorching equatorial sun beats down on glass facades, and the heat generated by high-density crowds and electronic equipment exposes the critical shortcomings of traditional cooling systems in terms of energy efficiency and reliability.

Faced with these issues, the SSS Building’s management team conducted rigorous evaluations during its renovation and finally chose MULTISTACK’s oil-free chillers with cutting-edge technology.

Q: Why choose MULTISTACK’s oil-free chiller over traditional solutions?

A: Three technological breakthroughs to precisely resolve the "three highs" challenge

1. Solving High Energy Consumption

Traditional centrifugal units rely on mechanical bearings, where friction leads to significant energy loss and poor efficiency at partial loads.

VS

MULTISTACK’s oil-free chiller adopts aerospace-grade magnetic bearings technology, suspending the compressor rotor to eliminate mechanical friction. This design reduces friction loss to just 2% of that of the traditional units, while variable frequency technology ensures high efficiency at all loads. With COP 12 and over 50% energy savings at partial loads, MULTISTACK chiller’s energy costs can be reduced significantly.

2. Eliminating High Noise Pollution

Traditional central air conditioning systems generate intense noise due to mechanical bearings and gears, disrupting office environments.

VS

MULTISTACK’s oil-free chillers deliver zero-friction operation, reducing vibration to near-zero levels and significantly lowering compressor noise. This eliminates the need for additional soundproofing measures, directly creating a quieter workspace.

3. Reducing High Maintenance Costs

Traditional centrifugal chillers have complex oil systems, requiring regular maintenance, oil changes, and costly maintenance.

VS
MULTISTACK’s oil-free design completely removes the oil system, eliminating annual cleaning. Only simple descaling of evaporators and condensers is needed, with maintenance costs as low as RMB 1,000 to 2,000 per session.

Amid Manila’s skyline, the SSS Building’s air conditioning upgrade is more than just a functional improvement - it marks a critical breakthrough in cooling technology for Southeast Asia’s commercial buildings. By addressing the industry’s pain points of high energy consumption, noise pollution, and maintenance costs with oil-free technology, it provides a replicable, high-efficiency solution for tropical office towers. As MULTISTACK’s oil-free technology gains traction, commercial buildings in Southeast Asia are gradually moving away from traditional high-carbon cooling models, embracing an energy-efficient, tech-driven transformation toward a sustainable, low-carbon future.
