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.

Plug and Play

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

ATEX Components

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

Isolated Electrical Cabinet

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

Compressors

Frascold screw compressors featuring ATEX motors provide very high energy efficiency and exceptional durability. These compressors can optionally be controlled by frequency converters, allowing for speed modulation that stabilizes temperature by adjusting compressor operation in close relation to the load, thereby conserving energy.

Heat Exchanger

High-performance brazed plate heat exchanger made of 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 limited rotation speed, enhancing safety with 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 control of all functions of the chilled water production unit.

Optimized Performance

The optimized design of these units, combined with the high-performance R290 refrigerant, enables accreditation of SERP and ESEER ratios that align with 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 strategy, allowing for optimized returns on investment across various industrial sectors.

Safety

The Zero Leaks design, along with the use of ATEX components, provides the EKO.E line units with maximum safety while ensuring operational longevity.

Reduced Noise

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

Environmental Respect

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

Modularity

The EKO.E units offer great modularity with an infinite array of options and configurations (over 5,000 different configurations) to adapt to each of your processes.
