The free-cooling option makes use of favorable ambient and load conditions, harnessing 'free' cooling from the environment to augment or replace mechanical cooling via the chiller's compressors, reducing energy consumption and running costs.
The heat recovery system enables chillers to produce domestic hot water at up to 80deg C, while continuing to provide cooling, useful for applications such as hotels, hospitals and industrial processes requiring hot water.

Indoor air quality(IAQ)
At CIAT, air quality rests on a number of key principles: the elimination of contaminants, control of legionella and bacteria in water, condensate disposal and fresh air management. Using these four pillars, we are able to:
  • Effectively fight against airborne nosocomial diseases,
  • Control airborne biological contamination,
  • Ensure excellent indoor air quality by reducing particulate pollution, such as PM 2.5,
  • Guarantee improved hygiene by removing condensates.
Our knowledge of microbiological, particulate and chemical pollutants in the air enables us to design solutions which fully comply with current regulations (NF S 90-351, VDI 6022).
Renowned today for the high indoor air quality it delivers, CIAT is committed to ensuring you enjoy excellent levels of comfort. Thanks to our unique systems, we control the minimum and maximum temperatures, the relative humidity level and the air circulation speed. The comfort test bed in our CIAT R&I Centre enables us to recreate the actual conditions of a room or consultation office. As a result, we can create full-scale simulations according to the ISO 7730 standard and guarantee you enjoy a comfortable indoor environment.

Our COMFORT LINE and COADIS LINE product ranges guarantee a high level of comfort for our customers.

Our BluEdge service platform offers indoor air quality assessments audits, to test air quality and implement upgrades to help ensure optimal filtration, ventilation, airflow and controls.

CIAT chose the R-32 refrigerant which is able to improve performance and reduce direct greenhouse gas emissions by up to 77%, compared to the previous range using R-410A refrigerant on air-cooled heat-pump and chiller range.

R-454B refrigerant has been selected as the optimum solution for use in rooftop applications. With a global warming potential (GWP) of 466, R-454B's overall carbon footprint is more than 80% lower than HFC R-410A, the refrigerant it replaces.

Our BluEdge service team is now able to give you information about units able to be retrofitted with an environmentally sustainable refrigerant. Service Team has started a development to be able to retrofit all equipments in the near future.
  • By choosing a unit with a low global warming potential (GWP) refrigerant
  • By using the free-cooling and heat recovery option (The heat recovery system enables chillers to produce domestic hot water at between 65-80deg C, while continuing to provide cooling, useful for applications such as hotels, hospitals and industrial processes requiring hot water).
  • With our advanced control solution, we help you to improve energy efficiency up to 25%, by optimizing pumps, fans, and controls.
The European Ecodesign directive aims to support the design of products which combine energy efficiency and the sustainable use of resources. The objectives are:
  • 32,5% energy efficiency improvement
  • -40% greenhouse gas emission
  • 32% share of renewable energy

SEPR (Water chiller indicator, process application):
Energy calculation for a typical cooling process application in average climate conditions: annual cooling demand (kWh)/annual energy consumption (kWh)

SEER (Water chiller indicator, comfort application):
Energy calculation for a typical cooling comfort application in average climate conditions: annual cooling demand (kWh)/annual energy consumption (kWh)

SCOP (Heat pump indicator, all applications):
Energy calculation for a typical heating comfort application in average climate conditions: annual heating demand (kWh)/annual energy consumption (kWh)

In order to reduce greenhouse gases, the European "F-Gas" regulation intends to gradually phase out the use of certain refrigerant fluids used in chiller installations by 2030.

Domestic air conditioning and comfort:

  • Portable air conditioning and standalone hermetic portable air conditioning units: refrigerant fluids with GWP ≥ 150 banned in 2020
  • Air-conditioning heat pumps and split units with a charge < 3 kg: refrigerant fluids with GWP ≥ 750 banned in 2025

Food cold chain:

  • Fixed refrigeration equipment (excluding applications < -50 °C): refrigerant fluids with GWP ≥ 2500 banned in 2020
  • Multipack centralized refrigeration systems (rated cooling capacity ≥ 40 kW): refrigerant fluids with GWP ≥ 150 banned in 2022
Yes, our BluEdge service team is able to handle this requirement.
