Kaltra screw chillers serve four-star hotel in Malaga, Spain

January 8, 2018

In the last week of 2017, Kaltra Innovativtechnik completed installation and commissioning work on the chiller replacements for a four-star luxury hotel located in Malaga, Spain.


The customer experienced inadequate comfort air conditioning from the existing air-cooled chillers and escalating operating costs. The hotel operator called on Kaltra for a replacement to reduce energy consumption, improve the reliable, smooth and quiet operation of the system.


We provided an installation which consists of two Lightstream Screw chillers equipped with E•VAP™ evaporative pre-cooling system which decreases the temperature of the air entering condensing coils by an average of 7 degrees, thus reducing the use of compressors during the hottest hours.


The Kaltra Lightstream Screw is an air-cooled screw chiller which ensures industry-leading energy efficiency in a reduced footprint, which makes it suitable for retrofit applications.


The comparative analysis estimated a 40 percent gain in efficiency with the evaporative pre-cooling system and latest microchannel condensing coils used in the chiller design.


Kaltra also provided startup and commissioning services, including the integration of new 740kW rated chillers with the existing chilled water system and by using a new HVAC control system to the building.


The contract includes Tier II maintenance package with remote plant monitoring and energy management. Remote visibility will ensure maximum system uptime via predictive maintenance and reduced energy costs through the performance optimization.


Kaltra is a provider of innovative air conditioning and refrigeration products for a whole host of applications, including process cooling, comfort air conditioning, mission-critical installations, and many other where reliability and energy efficiency are key factors.
