Product Overview
-
The 30XW liquid chillers are the premium solution for industrial and commercial applications where installers, consultants and building owners require optimal performances and maximum quality.
The 30XW liquid chillers are designed to meet current and future requirements in terms of energy efficiency, flexibility of use and compactness. They use the most reliable technologies available today:
- Twin-rotor screw compressors with a variable capacity valve
- Single refrigerant R-134a
- Pro-Dialog control system
- Flooded heat exchangers that are mechanically cleanable
To meet to all environmental and economic requirements, the 30XW is available in two efficiency classes:
- Standard-efficiency 30XW units that offer an optimised balance of technical and economical aspects, while at the same time boasting superior energy efficiency.
- High-efficiency 30XW-P units that offer unequalled energy efficiency to satisfy the most stringent demands of building owners wanting to reduce operating costs to the minimum.
Features & Benefits
- Twenty standard-efficiency sizes with nominal cooling capacities from 273 to 1732 kW and eleven high-efficiency sizes with nominal cooling capacities from 509 to 1756 kW.
- Designed for industrial and commercial applications that require optimal performances and maximum quality.
- Two versions: 30XW for air conditioning and refrigeration applications, and 30XWH for heating applications (see separate entry).
- Two efficiency classes: the standard-efficiency 30XW offers an optimised balance of technical and economical aspects and superior energy efficiency; the high-efficiency 30XW-P offers unequalled energy efficiency at minimised operating cost.
- Exceptional full load and part load energy efficiency: Eurovent energy efficiency class “A”, EER of up to 6.15 kW/kW and ESEER of up to 8.0 kW/kW (30XW-P)
- Twin-rotor screw compressors with high-efficiency motor and a variable capacity valve for exact matching of the cooling capacity to the load.
- Use of R-134a refrigerant with zero ozone depletion potential.
- Pro-Dialog control system.
- Flooded mechanically cleanable heat exchangers.
- Economizer system with electronic expansion device for increased cooling capacity (30XW-P).
- Simplified electrical connections.
- Units are run-tested before shipment and include a quick-test function for fast commissioning.
- Leak-tight refrigerant circuit; two independent refrigerant circuits from 1000 kW upwards.
- Comprehensive endurance tests.
- Aquaforce offers multiple remote control, monitoring and diagnostic possibilities.
