WET-RTF-R 0102 – 1204

Water cooled rooftop unit for WLHP and WSHP, with static plate heat recovery
Total cooling capacity 44,8 – 468 kW

NECS 0202T - 0612T
Autonomous reversible water-cooled Rooftop unit, for the thermohygrometric treatment, filtration and renovation of the air, with plate type static heat recovery. These units are ideal in high volume environments and highly crowded spaces – e.g. shopping centers with water loop system. In these applications the percentage of fresh air necessary to maintain the air quality level established by local rules is particularly high; this is why the use of an heat recovery is strongly recommended. Hermetic rotary scroll compressors with R410A refrigerant, double refrigerant circuits, 42 mm sandwich paneling, aluminum profiles for the structure, coated galvanized steel base and centrifugal fans. Both winter and summer operation, FCC configuration with supply and return fans that allow high flexibility for the direction of the air flows, and return, expulsion and external air motorized dampers.

PC – function for constant water flow system
PV – function for variable water flow system
PP – function for disposable water system


    Climaveneta’s units offer the opportunity to choose different supply and return airflows directions.
    The static plate heat recovery provides a constant and effective recovery of the sensible energy from the exhaust air. In winter mode the efficency can reach values higher than 50%, that, together with the zero energy consumption of the component, grant an effective energy and economic saving.
    The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0)
    The wide working field and the accurate design of the unit ensure optimum performances and comfort, with a continuous and constant thermal supply also during heavy thermoigrometric working conditions
    Refrigerant lines and regulation devices are easily accessible and separated from the air treatment section. Thus meaning a reduction of contamination accidental risk and allowing the valves adjustment while the unit is running.


  • High efficiency filters: electronic or rigid pocket F7
  • Hot gas post heating
  • CO2 control sensor for air quality
  • Enthalpy free-cooling
  • Set-up for remote connectivity with ModBus/Echelon protocol cards
  • Remote control keyboard (distance to 200m and to 500m)


  • AIR3000
    The controller AIR3000 offers advanced functions and algorithms. The keypad is generously sized with full operating status display. The controls and detailed LCD make access to unit settings easy and safe. Temperature regulation is based on step-wise proportional logic referring to the return air temperature. The diagnostics includes full management of alarms with the black-box and alarm logging functions for enhanced analysis of the unit operation. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Echelon LonWorks. Compatibility with the remote keyboard managing up to 10 units. Availability of an internal real time clock for operation scheduling (4-day profiles with 10 hour belts). The defrost adopts a proprietary self-adaptive logic, which features the monitoring of numerous operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
