Reversible Heat Pumps (Air-to-Water)
Air-to-water heat pumps are systems that use ambient air as a heat source to heat a working medium (water or glycol). Heat extracted from ambient air at a lower energy level can be upgraded to a higher energy level by consuming electrical energy, which is required to operate the compressor and other electrical components.
Frigo Plus heat pumps use the natural refrigerant R290 (propane), which has an exceptionally low global warming potential GWP < 1. This natural refrigerant has zero ozone depletion potential (ODP = 0). Accordingly, it is exempt from the restrictions imposed by F-Gas legislation, namely Regulation (EU) 2024/573 on fluorinated greenhouse gases.
Reversible air-to-water heat pumps are characterized by their ability to reverse the operating process, switching from heating to cooling mode and vice versa. Reversibility is achieved by changing the direction of refrigerant flow within the unit using a four-way valve. Depending on outdoor weather conditions or system demands, the user can switch or reverse the operating mode. It is important to note that air-to-water heat pumps also utilize the reversible process for defrosting the air heat exchangers during heating operation.
Heat pumps can also be designed exclusively for heating purposes. In such configurations, process reversal is still available but solely for the purpose of defrosting the air heat exchangers (evaporator). The defrosting process is managed by the unit’s main controller.
OUR SERIES
Miniline
The MINILINE heat pump series is developed to cover heating needs for smaller-capacity systems. MINILINE heat pumps can be reversible, meaning they can also operate in cooling mode. Therefore, MINILINE heat pumps are a strong solution for year-round heating and cooling demand. Depending on the required heating capacity, MINILINE heat pumps use reciprocating or scroll compressors that are designed and certified for operation with flammable refrigerants. The unit is intended for outdoor installation.

Midline
The MIDLINE heat pump series is developed to cover heating needs for medium-capacity systems. MIDLINE heat
pumps offer numerous options for integrating hydraulic equipment inside the unit housing, enabling more
practical and simplified system design. They can also be designed as reversible heat pumps to cover heating
and cooling demand throughout the year.
MIDLINE heat pumps use semi-hermetic reciprocating compressors designed and certified for operation with flammable refrigerants. The units are intended
for outdoor installation.

Flexy
The FLEXY heat pump series is developed to cover heating needs for medium and larger-capacity systems. If FLEXY heat pumps are designed as reversible, they can also operate in cooling mode. Therefore, reversible heat pumps are a strong solution for year-round heating and cooling demand in industrial and commercial systems. FLEXY heat pumps use semi-hermetic reciprocating compressors designed and certified for operation with flammable refrigerants. The units are intended for outdoor installation.
