Technical specifications

Decreasing harmful emissions, whether they stem directly from the use of greenhouse gases or indirectly from electricity production for heat pump usage, is the first and most important pillar on which Galletti bases its Advanced design solutions.

Following this path, Galletti presented HTH, a revolutionary line of air cooled modular heat pump chiller powered by low GWP refrigerant and an EVI scroll compressors. With its wide operating range and outstanding performance, this product is the ultimate solution to gradually reducing the reliance on fossil fuels for heating and cooling buildings.

The range consists of multiple models with heating and cooling capacities ranging from 14 to 54 tons (R410A) and from 29 to 53 tons (R454B). 

R454B is the latest generation A2L refrigerant capable of guaranteeing one of the lowest GWPs on the market, equal to only 467.

The use of top-quality components at the cutting edge of technology makes HTH modular heat pump chillers state of the art in terms of efficiency, reliability, and operating limits. 

The main strong point of this series is the large operating field with continuous operating down to -4°F and production of hot water up to 149°F (R410A) or 146°F (R454B).

HTH is a low noise design and embedded with advanced adjustment logics (like domestic hot water production with an external 3 way valve), and remote 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 order to increase the efficiency at partial loads, the HTH range uses up to 4 compressors.
