Technical characteristics

EvitecH is Galletti’s new high efficiency multiscroll units equipped with R410A steam injection compressor. The  range  consists  of  10  air-water  models  available  as chiller  and  heat  pump,  with  cooling  capacities  from  50 to 180 kW. The main strongpoint of this series is the large operating field, both in terms of maximum hot water temperature (65°C  with  -11°C  of  external  air  temperature)  and  minimum air temperature at which the continuous operation is allowed (-20°C). The  range  allows  high  configurability  from  an  acoustic point  of  view,  having  a  wide  range  of  accessories  designed to reduce noise emissions. The advanced control, always present in the whole range, allows a continuous monitoring  of  the  operating  parameters,  advanced  adjustment logics, and connectivity. The  modular  structure  with  V  configuration  condensing coils is designed to optimize air-side heat exchange, to  ensure  structural  strength  with  a  reduced  footprint, and  to  maintain  maximum  accessibility  to  the  basic components. In addition to high efficiency in terms of nominal conditions (Eurovent A-class), in order to increase the efficiency at partial loads, the whole range consists of tandem solutions (2 compressors on a single refrigerant circuit).The  configuration  of  units  with  the  Hydro  Smart  Flow kit allows an increase of the efficiency and extends the working area of the cooling mode.

Main components

Structure

The range is designed modularly, replicating the optimized structure of V configuration condensing coils and fans. Its design ensures stability, sturdiness even during the most critical phases (such as transportation), and maximum accessibility to components in every unit.

Hydro smart flow

The HSF kit (standard for models 52 and 62) is placed on the unit’s hydronic side and consists of a 4-way valve and a kit. Hydro Smart Flow, which is activated at the time of seasonal changeover, reverses the direction of the water flow over the plates to be consistent with the flow of the refrigerant. In this manner heat exchange always occurs in counterflow, this optimizing the unit’s operation in the summer and winter seasons and extending the unit’s operating range.

Upwind

EvitecH is designed with an innovative technology which allows the refrigerant to get into the battery from the same direction when the cycle is inverted, with a constant counter-current exchange with air. This advanced technology considerably reduces the risk of ice generation on the finned heat exchangers.

Scroll compressors with vapour injection

The range consists of single and dual-circuit models in order to offer maximum redundancy. The distribution of load in multiple power steps and the use of tandem solutions (2 compressors on a single circuit) ensures maximum efficiency at partial loads and therefore greatly increases seasonal efficiency. Intercooled compression with steam injection allows a better control of the end-compression temperature, keeping it within the limits imposed by the compressor envelope, even in the most unfavorable working conditions (low evaporation pressures and high compression pressures), this results in one of the largest operating field in the market.

3-way valve

This is a smart kit able to convert EvitecH heat pumps in multi-function units in order to fulfill every necessity of the hydraulic air-conditioning plant. It allows domestic hot water priority production thanks to Galletti thermal accumulators of the TP or TN series. The switching of the valve is managed by the on-board microprocessor control of the unit.
