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

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

RTHD High Seasonal Efficiency
Increased Part Load Efficiency (ESEER) +25% vs market average at fixed speed
+17% vs Trane extra efficiency models
Decreased Inrush Current
Starting current lower than with standard Star-Delta starter
Superior Capacity Adjustment vs Load RTHD fixed speed: 20% min.
RTHD HSE: 15% load min.
RTHD HSE can be provided with a built-in Harmonic Filter
Reduction % of Total Harmonic Distortion (THiD) transmitted
to the electrical network
Compliance with local standards and recommendations
Prevents from component breakdown by harmonic pollution
