Introduction

RAW SERIES MULTIFUNCTIONAL, MULTIPURPOSE AND ALL-IN-ONE 6-20 kW

RAW is an all in one split air-water heat pump, able to fully meet heating, cooling and domestic hot water production needs; it can operate with outdoor temperatures down to -20°C and produce hot water up to 65°C. It is completed by an exclusive compact hydronic module, equipped with a 200 l puffer for sanitary technical water, 95 l inertial thermal flywheel, instantaneous DHW production via a 25 l/min brazed plate heat exchanger, expansion vessels, safety valves, hydraulic filters and electronic pumps for the plumbing system, sanitary water and source circuits.

The heat pump is available in two versions:
• M for 2-pipe systems with domestic hot water, in total recovery mode
• H for 2-pipe systems with domestic hot water

  • Villas
  • Apartment buildings
Description

Total heat recovery

The dedicated total heat recovery refrigeration circuit through a parallel condenser allows the RAW heat pump to meet the heating and DHW system requirements, without having to reverse the refrigeration cycle in response to different environmental heating and cooling requests.

All-in-one hydronic module

The all-in-one hydronic module is a complete thermal power plant, which can also be installed in confined spaces and which integrates perfectly with the geothermal system, to achieve the highest levels of efficiency and energy savings.

Operation

Technical overview

Technical specifications

DOUBLE EEV

The use of the electronically controlled double expansion valve (EEV) maximises RAW performance under any temperature condition, stabilises and optimises operation, regardless of the length of the refrigerant line.

WIDER PITCH FINNED COIL

The coil has a wider fin pitch and is applied a hydrophilic coating to prevent the formation of surface condensation – a key factor to reduce the number of defrosting cycles by up to 30%.

MODULATING FLOW CONTROL

A microprocessor supervises the electronic pumps installed inside the unit, to ensure water flow rate control at constant temperature or constant delta T. This system guarantees maximum system adaptability to every need.

LOW NOISE

Hibox soundproofing of the compressor via a dedicated sound jacket and box, the oversized EC fans with 50% rotation speed and the soundproofing front grille guarantee the highest level of acoustic comfort.
