SCROLL CHILLERS

Easystream

A family of low-sound, packaged scroll chillers available in air-cooled and water-cooled designs for plant room applications 50 to 500kW

50-500kW

PRODUCT OVERVIEW

Packaged chillers with multiple scroll compressor technology

The Easystream family of the high-efficient scroll chillers includes the air-cooled and water-cooled models suitable for plant room or outdoor installation in commercial, residential, and industrial applications.

 

These scroll chillers are developed to fully comply with today’s strict noise pollution regulations and optimized for R410a refrigerant. Multiple scroll compressor technology implemented for Easystream chillers for cooling capacities of up to 500kW.

Scroll compressors

RELIABLE SOLUTION FOR LONG-LIFE OPERATION

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

 

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

 

Customers of Easystream scroll chillers can benefit from proven reliability, low sound levels, low vibration, and minor operating and maintenance costs.

Evaporators

The Easystream family features brazed plate heat exchangers: brazing the stainless steel plates together eliminates the need for gaskets and thick frame plates, which makes the heat exchanger compact.

 

The special plate design guarantees a consistent braze joint at the plate overlap and makes for stronger and more 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 verification, highest performance and the longest possible service lifetime are guaranteed.

ELECTRONIC EXPANSION VALVES

Accurate control of superheat with the Easystream scroll chiller operating at part load achieved with electronic expansion valves. Fitting EEV permits a reduction in power consumption of up to 30% by controlling the refrigerant flow at reduced head pressures.

 

The EEV used in Easystream scroll chillers are new generation valves designed for precise liquid injection in an evaporator and includes balanced cage and slider assembly operated by direct driven motor technology. This ensures solenoid-tight shut-off in both flow directions, thus providing smooth operation of the system.

The valve incorporates a powerful bi-polar motor which precisely controls flow regulation.
