Multifunctional units dedicated to 2, 4 and 6 pipes systems
RHOSS EXP-Polyvalent system is the intelligent solution to air conditioning requirements in plants where the heating demand is simultaneously or independently combined with a cooling request.
The units adapt well to various types of systems, thereby guaranteeing unique efficiency and versatility.
The units are designed to reach energy efficiency at high levels and guarantee fields of work that allow operation throughout the year.

What is a 2 (two) pipes system?
In this plant, there is the need for space cooling in summer and for space heating in the winter season (typical application with terminal units, e.g. fan coils). In addition, there is a simultaneous request for DHW all year round. Sometimes there is also the request for hot water at a higher temperature.
Typical units used in this system are traditional chillers or heat pumps with the integration of a HR (available during summer only) and a boiler.
What is a 4 (four) pipes system?
In this type of plant, there are requests for space cooling and space heating all year round (typical application with hydronic terminals, e.g. fan coils with double coils). In this case, the thermal loads to satisfy can be simultaneous and opposite. Sometimes there is also the request of hot water at a higher temperature (6 PIPES).
Using a chiller and a boiler, or a chiller + HR and a boiler (to limit the use of the boiler in summer), or a heat pump + HR and a boiler are the simplest ways to build this system.
What is a 6 (six) pipes system? Hot water up to 70°C
This is a 4 pipes system with an additional request for hot water at a higher temperature (6 PIPES). As a result of the option to manage 6 pipes systems, WinPOWER EXP units can produce water up to 70°C in the dedicated heat exchanger.
