TECS-FC: merging renewable sources with the ultimate technology advancements for the best operating efficiency

Climaveneta has expanded its line of free-cooling units and launched TECS-FC: a high performance air cooled chiller range with magnetic levitation compressors, flooded evaporator and EC fans.

Climaveneta has expanded its line of free-cooling units and launched TECS-FC: a high performance air cooled chiller range with magnetic levitation compressors, flooded evaporator and EC fans.

Dedicated to IT-cooling and process cooling applications where cooling demand is constant all year round, the new free-cooling chillers use the cold outdoor air for cooling the indoor environment, fully harnessing the savings potential contained in this precious renewable source.

TECS-FC features a smartly managed free-cooling system: according to the outdoor air conditions and operating water temperature, the chiller automatically switches between total free-cooling, hybrid free-cooling and mechanical cooling mode. As the outdoor air temperature drops 1 degree below the returning water temperature, the unit starts using outdoor air to cool water (hybrid free-cooling), partially benefitting from the free-cooling effect. The free-cooling capacity grows with lower air temperatures, until it covers the entire cooling demand and the compressors are completely switched off (total free-cooling), thus achieving incredibly high operating efficiency (EER values around 220).

But premium performance results are not only delivered during the total free-cooling mode. Within the hybrid and mechanical operations, in fact, the top level technology of the compressors with magnetic levitation brings enormous benefits in terms of performance, adjustment, vibrations and weight, keeping the unit EER efficiency values always above the competitive technologies. Climaveneta’s 10-year expertise in managing this powerful technology provides the market with a unit that really can make the difference in terms of reducing operating costs while providing the utmost reliability.

Every single detail is manufactured according to the best quality standards, from the sturdy and durable structure to the optimised geometry of the flooded evaporator (manufactured entirely in-house); from the dedicated and exclusive design of the air heat exchangers, made of both refrigerant and water tubes located in one single coil, to the EC fans on the air management side, selected for their accurate adjustment of the rotational speed and its extremely silent operation.

At the core of the TECS-FC is the advanced controller with proprietary settings dedicated to the precise management of all the unit’s different dynamics and operating modes. Also available with the touchscreen display, the controller boasts an intuitive and user-friendly interface with LED icons, designed to ensure a clear reading of all the variables and immediate view of all circuits.

TECS-FC is an ideal solution for the most demanding projects, featuring constant cooling demand all year round, namely data centres, process cooling and telecommunication infrastructures. These are mission critical applications, where the main drivers are not only the highest efficiency but also the absolute cooling dependability. To protect the customer from any risk of cooling interruption, Climaveneta has developed dedicated countermeasures. The Fast Restart function, for example, ensures, after an unexpected power failure, an immediate start-up of the chiller operation within 26’’ seconds from the power coming back on.

Additionally, TECS-FC, thanks to an ATS (Automatic Transfer Switch), can be connected to two separate power lines. In case of a main line power outage, the ATS automatically switches over to the other line, granting uninterrupted power supply to the unit. The double power supply grants the cooling system dependability and makes TECS-FC ideal for the premium TIER III and TIER IV design topologies, the highest standards of reliability.

The new chiller is now available in both the standard (K) and high efficiency (CA) versions, delivering cooling capacities from 302 to 1649kW. As a further option, the unit can be selected with the No-Glycol configuration and with the new green HFO 1234ze refrigerant, providing customers with a vast array of design possibilities aimed at satisfying even the most demanding project requirements.
