SCROLL CHILLERS

Ultracompact

Compact packaged air-cooled chillers with scroll compressors and microchannel condensing coils for air conditioning and process cooling

50-300kW

PRODUCT OVERVIEW

Versatile solution for chilled water production

Ultracompact air-cooled chiller family provides capacity-matched cooling, accurate thermal parameters, and chilled water flow.

 

These scroll chillers feature compact design, lightweight aluminium enclosure and deliver best-in-class efficiency thanks to high-quality engineering and first-grade components.

 

Ultracompact scroll chiller is an excellent choice for process cooling and air conditioning applications, as well as for commercial refrigeration systems.

Scroll compressors

RELIABLE SOLUTION FOR ENSURED CONTINUITY IN CRITICAL APPLICATIONS

The combination of an energy-efficient motor and an optimized scroll wrap for refrigeration applications delivers a high efficiency in Ultracompact’s fixed-speed compressors.

 

Reliability is built into this compressor range, from compliant scroll design and engineered bearings to simplified design. Thermal fault protection also contributes to excellent reliability.

 

Customers of Ultracompact air-cooled chillers with fixed-speed compressors can benefit from proven reliability, low sound levels, low vibration and low operating and maintenance costs.

Evaporators

Ultracompact series features brazed plate heat exchangers: brazing the stainless steel plates together eliminates the need for gaskets and thick frame plates, resulting in a compact heat exchanger.

 

The special plate design guarantees a consistent braze joint at the plate overlap and ensures a more robust and leak-proof heat exchanger. The brazing material seals and holds the plates together at the contact points ensuring optimal heat transfer efficiency and pressure resistance. Using advanced design technologies and extensive checks guarantees the highest performance and longest possible service lifetime.

BRAZED PLATE HEAT EXCHANGERS

Microchannel condensers

EXCELLENT HEAT TRANSFER PERFORMANCE
REDUCED CONDENSING TEMPERATURES
LIGHTWEIGHT AND ROBUST DESIGN

All-aluminium microchannel condensing coils used in Ultracompact air-cooled chiller range allows achieving the number of advantages, including low airside pressure drops, higher heat transfer rate, and closer approach temperatures.

 

The end result is up to 40% higher energy efficiency in comparison to finned tube coils. Smaller coil face, its thin design, up to 50% less weight, and less refrigerant charge translates to lower cost.

 

Based on the all-aluminium construction, microchannel condensing coils are subject to significantly less galvanic corrosion than traditional fin/tube design, in that there are no dissimilar metals.

Power-saving fans

EC-TYPE FANS WITH REDUCED POWER CONSUMPTION

Ultracompact’s new intelligent fan system consisting of profiled, sickle-shaped axial fans, multifunctional air guide vanes, and diffusers - provides maximum flexibility, lowest possible sound emissions, and highest degree of energy efficiency.

Modern EC motor technology not only produces savings in full-load operation - it is exactly when operating under partial load that EC motors lose much less of their efficiency.
