Groupe d’eau glacée à condensation par air - EKO.E/MT - R290 | CTA

Cooling process

Because there is nothing more precious than your processes, for 30 years we have developed refrigeration systems combining modularity and reliability for the preservation and optimization of your production tools.

Air cooled water chiller – EKO.E/MT – R290 Semi-hermetic compression

9.5 Kw > 393 Kw
Air cooled water chiller – EKO.E/MT – R290 Semi-hermetic compression

Leader in process cooling for 30 years, CTA, a French manufacturer, leverages its experience in researching and designing products tailored to the evolving needs of industrial markets. Since the early 2000s, we have established the e3 label—Ecology, Efficiency, Environment—which is internationally recognized by our peers and aims to create products based on these three values that are at the core of our DNA.

Our expertise and skills are embodied in the "Natural Fluid R290" product line, with the EKO.E range being at the forefront, perfectly aligning with temperature control and environmental respect. Dedicated to producing negative cooling between 0°C and -10°C, the new generation of the EKO/MT range represents a revolution in the world of industrial water refrigeration, offering performance levels from 7 to 393 kW. Now available in two versions, including a high energy efficiency option, this new chilled water production unit retains CTA's 100% industrial DNA and incorporates the latest technologies, making it the optimal solution for your medium-power industrial and agro-food applications.

CARACTÉRISTIQUES PRINCIPALES

Réfrigérant R290 Froid Circuit frigorifique 1 Circuit frigorifique 2 Compresseur semi-hermétique Plate heat exchanger Multi-tubular exchanger Ventilateur hélicoïde

Plug and Play

With an integrated hydraulic kit (pump, reservoir, and pressure transducer), the EKO air-cooled chillers are ready for immediate installation into your water networks.

ATEX Components

Prioritizing maximum safety, our solutions are equipped with numerous ATEX components, ensuring the highest level of security under all operating conditions.

Isolated Electrical Cabinet

The specific design of our electrical panels, located outside the units and complying with the highest safety standards, prevents any risk of flammability in case of refrigerant leakage (Electrical supply: 400/3/50 + 230/1/50 for gas detector).

Compressors

Featuring semi-hermetic Frascold compressors with ATEX motors that deliver exceptional energy efficiency and durability. These compressors can optionally be controlled by frequency converters to modulate speed, stabilizing temperature by adjusting compressor operation in relation to the load, aimed at conserving energy.

Heat Exchanger

High-performance brazed plate heat exchanger made from AISI316 stainless steel, fully insulated with neoprene and anti-condensation materials. In the integrated version, the hydraulic circuit consists of a centrifugal pump, a buffer tank, and all safety components.

Fan & Condenser

The latest generation fan operates with a limited rotation speed and optimized safety features due to its protective grille against accidents. Its aerodynamic profile and streamlined blades ensure high efficiency while reducing noise levels.

Control

The connected pCO Carel regulation system allows for the management and regulation of all functions of the chilled water production unit.

Optimized Performance

The optimized design of these units, combined with the high-performance R290 refrigerant, allows for the accreditation of SERP and ESEER ratios that meet market expectations. With an EER over 12% higher than comparable machines using R134a/R449/HFO 1234ze, the EKO.E solutions are part of an environmentally responsible and energy-efficient approach, providing optimized return on investment across various industrial sectors.

Safety

The Zero Leaks design and the use of ATEX components provide the EKO.E line units with maximum safety while ensuring long-term operational reliability.

Reduced Noise

The unit design and the use of high-performance and quiet components contribute to limited noise emission, particularly in the Low Noise and Super Low Noise versions.

Environmental Respect

The EKO.E line is 700 times less polluting than traditional chilled water units (HFC), utilizing the natural refrigerant R290 to address key energy efficiency challenges with a limited ecological footprint (GWP = 3). HC R290 fully complies with the F-Gas Regulation 517/2014, which mandates a significant reduction in greenhouse gas emissions and promotes the use of natural refrigerants. In this regard, HC R290 is uniquely positioned to meet these objectives sustainably and durably.

Modularity

The EKO.E units offer exceptional modularity with an infinite array of options and configurations (over 5,000 different configurations), allowing for tailored solutions to meet each of your processes.
