Technical characteristics
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
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 V-IPER unit.
Electronic valve
Supplied as a standard feature, it allows optimization of operation and reduction of power consumption as a result of faster transients.
Upwind
V-IPER implements a novel technology that allows, when the cycle reverses, to maintain the same direction of flow of the coolant through the condensing coils and to maintain air heat exchange that is always in counterflow. This advanced technology makes it possible to consistently reduce the risk of frost formation on the condensing coils. At the same time, UPWIND ensures optimization of heat exchange during both evaporation and condensing, allowing the Galletti heat pumps to be categorized as Class A (high efficiency) for both heating and cooling.
Microchannel
The entire chiller range features microchannel condensing coils as a standard feature. The large exchange surface, the lack of copper-aluminum interface, and the perfect passage of air makes it possible to achieve the same performance while reducing the refrigerant charge by up to 40%, with obvious benefits from an ecological point of view. The Galletti microchannel condensing coils always have a standard epoxy and UV dual surface treatment that provide 2400 hours of resistance under salt spray test conditions, to offer maximum safety even in aggressive environments.
