Chiller Feature
For high ambient climates
GEOCLIMA HAS INTRODUCED a new oil-free centrifugal compres- sor chiller for high ambient climates.
The High Lift range, based on Turbocor’s high lift TTH-TGH compres- sor, uses the technological innovations of Geoclima’s Circlemiser series to guarantee the same performance in terms of energy efficiency even with extreme ambient temperatures up to 50°C (122°F).
Like the Circlemiser, the chiller employs the specially-designed cylindri- cal condensers that increase the heat exchange surface by 45%, and the cas- cade configuration of flooded evaporators to reduce energy consumption.
The High Lift range combines this technology with a new wrapping evaporative system, developed to integrate the benefits of the adiabatic system together with the already highly efficient system of the Circlemiser.
In addition to the traditional R134a, it can be specified with the lower GWP refrigerant R513A or the low GWP HFO R1234ze.

Free cooling without the add-ons
DAIKIN AIR-COOLED CHILLERS have been the choice for system de- signers who are focused on simplicity and low cost.
From small retailers to large commercial operations, Daikin chillers provide highly efficient comfort solutions for various HVAC applications.
A recent addition is the new air-cooled chiller range (EWAT-B) with R32 refrigerant and free cooling migration, which enables building systems to switch from mechanical cooling and to take advantage of prevailing out- door temperatures to meet cooling demands for air or water naturally, significantly reducing power consumption.
Leveraging its HVAC & refrigerant businesses, Daikin Industries was the world’s first company to introduce R32 in split system air conditioners and is expanding its use to the light commercial space, with its SkyAir se- ries and also to large scale commercial applications with air cooled chill- ers. R32 refrigerant has 66 per cent lower ‘Global Warming Potential’ fac- tor providing less risk of harm to the environment compared to commonly used refrigerant R-410. It is the only refrigerant that allows mi- gration to free cooling without the need for other add-on devices. Addition of glycol is not required, unlike standard water free cooling technologies, where its use is mandatory.
The new refrigerant migration system is available in two options, Light and Full options.
The Light refrigerant migration system delivers up to 25 per cent of nominal cooling capacity.
The Full option includes all the benefits of the Light version with an additional flood evaporator per circuit that works in parallel to the standard heat exchanger, improving the system’s performance. The cooling capacity of the Full system extends up to 75 per cent of the standard unit’s nominal cooling capacity, making it an economical solution for cooling in larger buildings.
Additional features include two efficiency versions (Silver and Gold), three sound configurations (Standard, Low, Reduced) and provides full customisation on project-specific requirements. An extensive list of op- tions and accessories includes hydronic kit configurations (single and twin pump, inertial tank, VFD) and many other solutions.
It is fully compatible with the ‘Daikin On Site’ cloud-based platform that offers advanced functionalities like remote monitoring, system optimisa- tion and preventative maintenance.
The new range (EWAT-B) is available for cooling only and heat recovery applications from 80kW to 700kW cooling capacity at nominal conditions.
