High Performance & Efficiency

Optimized Operating Costs : Patented Falling Filmevaporator technology

Uses significantly less refrigerantthan a similar-sized

chiller with flooded evaporator design

Offers better heat transferand more overall energyefficiency.

Patent by Trane

High reliability : Compressors

Direct Drive - 3000 rpm @ 50 Hz Only 3 moving parts

EVAPORATOR DESIGN for EFFICIENCY

Tranes Patented Falling Film Evaporator design not only

Increases efficiency by Increasing Heat Transfer Area but also

reduces Refrigerant Charge by almost 35%compared to units of

similar capacity. Also, the cost of Refrigerant replacement/top

up is very high for units requiring Higher charge of Refrigerant
