V-IPER

Viper is Galletti’s new high efficiency range, featuring Galetti’s most advanced technology in the R410A multiscroll units used in HVAC.

The range consists of 20 air-water models available as chiller and heat pump, with cooling capacities from 50 to 380 kW. The range’s main strongpoint is its high efficiency, not only as time efficiency (Class A Eurovent in chiller and heat pump mode) but especially as seasonal efficiency, aiming to permanently reduce annual energy consumption. In order to increase the efficiency at partial loads, much of the range is comprised of trio solutions (3 compressors on a circuit); furthermore, Viper employs components and adjustment logic that make it possible to manage the water-side flow rate modulation. 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.

V-IPER heat pumps and water chillers are designed for heating or cooling the water to be used in air-conditioning systems for residential, commercial or industrial use. Its high efficiency ensures a considerable reduction in consumption and the ability to operate in various weather conditions.

Main components

• Upwind: new technology that allows the refrigerant to keep the same direction of crossing of the coils and an exchange with air always in counter-current. This advanced technology makes it possible to considerably reduce the risk of frost forming on the batteries. At the same time, UPWIND ensures optimization of heat exchange in both evaporation and condensation, allowing Galletti heat pumps to be placed in class A in both heating and cooling
• Microchannel: the entire Chiller range features microchannel coils. The large exchange surface, the absence of copper-aluminium interface and the perfect air passage allow to obtain the same performance reducing the refrigerant charge up to 40%, with obvious benefits from an ecological point of view. The microchannel coils always make use of a standard double surface treatment which guarantees 2400 hours of salt spray tests, to offer maximum safety even in aggressive environments
• Structure: the range is developed modularly, replicating the optimized structure of V-shaped coils and fans. The design ensures stability, sturdiness even during the most critical phases
• Electronic valve: supplied as standard, it allows to optimize operation and reduce energy consumption thanks to faster transients
• Silenced execution: the units can be supplied in silenced execution, with soundproofing hoods, sound-absorbing compressor casing, Axitop diffusers positioned on the axial fans. This configuration allows, together with the night attenuation function, a significant reduction in sound power
• Hydro Smart Flow: available on request, it is set up on the hydronic side of the machine and consists of a 4-way valve and a special kit. Hydro Smart Flow intervenes in the seasonal changeover by reversing the crossing direction of the water flow plates, consistently with that of the refrigerant.
• Scroll compressors: the range consists of single and two-circuit models in order to offer maximum redundancy. The possibility of dividing the load into many power steps and the use of trio solutions guarantees maximum efficiency at partial loads and therefore greatly increases seasonal efficiency.

• High efficiency under part load conditions
• Intelligent modulation of the water flow rate
