Strengths of WCH-i 

• Pioneer in technology
  The technical solutions adopted place WCH-i on top of its category: the exclusive patented horizontal back to back centrifugal compressor, the economizer which further increases the efficiency by 6%, the falling film evaporator which reduces the refrigerant charge by 40% compared to a flooded exchanger, the capacity modulation with inverter, guarantee efficient and reliable operation of the unit at any application condition.
   
• Low noise operation
  WCH-i centrifugal chiller achieves one of the best sound levels on its category, proposing: sound pressure values (@ 1m) equal to 80 dB (A) and the almost total absence of vibrations.
   
• Compact Size 
  The space savings are an increasingly important aspect in the design of the building. The WCH-i units have a length measure less than 4 meters, which ensures very easy installation.
   
• Maximum adaptability 
  Capacity load from 100% to 15% and condenser leaving water temperature up to 40°C are able to satisfy the requirement of multiple operating conditions. Many options and accessories are available to suit the needs of each plant.
   
• Already complies with 2021 requirements
  The Commission Regulation 2281:2016, also known as Ecodesign LOT 21, sets minimum seasonal efficiency levels to place products on the European market, effective from 1st January 2018. The minimum seasonal efficiency levels will further increase from 2021 (Tier 2). WCH-i today is already compliant to both requirements.
   
• Perfect for LEED
  All WCH-i models satisfy prerequisites 2 and 3 of Energy and Environment thematic area. Furthermore, it matches the parameters of Credit 4 that allows to achieve 2 points (Leed 2009).
   

• Monitoring and remote interaction
  It is possible to monitor the unit operation and to diagnose any anomalies as soon as they arise.
  The unit is supplied as standard with a dedicated communication device, Clivet Eye, already installed on board, which records all data concerning unit operation, anomalies and alarms. If a Customer makes a claim, Clivet can display all the data related to each unit for any check or operation analysis and also intervene directly on the machine. Clivet Eye therefore guarantees significant advantages for plant performance, as it reduces the time needed to solve the problem by intervening directly from Clivet Office and reduces the intervention costs as it could avoid or in any case guide the visit of a specialized technician to the installation plant.
