Air cooled water chiller – EKO – R290 Semi-hermetic compression

As a French manufacturer and leader in the process cooling market for the last 30 years, CTA leverages its expertise in the research and design of products tailored to the evolving needs of industrial markets. In the early 2000s, we established the e3 label—ecology, efficiency, environment—internationally recognized among our peers, which aims to create products centered around these three core values that are fundamental to our DNA.

Our expertise is exemplified in the "Natural Fluid R290" product line, with the EKO.E range at the forefront, perfectly aligning with temperature control and environmental respect. Attentive to the needs of the most demanding industries and committed to a socially and environmentally responsible policy for over 10 years, we have developed advanced systems capable of cooling fluids from +20°C to -30°C.

CARACTÉRISTIQUES PRINCIPALES

Circuit frigorifique 1 Utilisation Intérieure Ventilateur plug fan

Plug and Play

The EKO air-cooled chiller range features an integrated hydraulic kit (pump, reservoir, and pressure transducer), making it ready for immediate installation in 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 compliant with the highest safety standards, prevents any risk of flammability in case of refrigerant leakage (Electrical supply ; V/ph/Hz + T; 400/3/50 + 230/1/50 for gas detector).

Compressors

The semi-hermetic Frascold compressors feature ATEX motors and provide exceptionally high energy efficiency, ensuring remarkable durability.

Heat Exchanger

This high-performance brazed plate heat exchanger is 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 necessary safety components.

Fan & Condenser

The latest generation fan operates at limited rotational speeds for optimized safety, equipped with a 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 align with market expectations. With an EER over 12% higher than comparable machines using R410a/R32, EKO.E solutions are part of an environmentally responsible and energy-efficient strategy, ensuring an optimized return on investment across various industrial sectors.

Safety

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

Reduced Noise

The unit's design, along with high-performance and quiet components, results in limited noise emissions, 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 utilizes the natural refrigerant R290 to address key challenges with high energy efficiency and 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 context, HC R290 is uniquely positioned to meet these objectives sustainably and durably.

Modularity

The EKO.E units offer exceptional modularity, featuring an infinite array of options and configurations (over 5,000 different configurations) to tailor solutions to each of your processes.
