Large split systems are versatile Solutions for Large Commercial Spaces

Suitable for commercial projects where there is a preference for using a split-system, and where there may be existing ducts or water-cooling infrastructure, Hitachi large commercial split systems are water-cooled for increased energy efficiency and are available as ducted or free-blow floor-standing units.
The system use floor standing indoor units and come in 2 types - free-blow or ducted systems. Designed for large open-plan spaces (free-blow) or multiple rooms (ducted) with capacities from 10-140kW, the system is water-cooled system and needs to connect to a cooling tower and water pumps etc (not supplied).

– Water-cooled Large Commercial Split Systems

Ideal where existing water-cooling infrastructure is in place, water-cooled systems enable higher efficiency with Cooling EER2 up to 4.38, and larger capacities from 10-140kW. The Floor Standing units occupy from just 0.4m2 to 2.5m2 making them a compact solution for large space cooling. Cooling water is piped from a cooling tower into the side of the unit.

– Choose from ducted or free-blow large split system

Available as free-blow units - incorporating multi-directional louvres built into the indoor floor-standing unit, while ducted units provide a simple duct flange connection on the top of the unit.

– Compressor safeguards built in

The compressor is fitted with a high-pressure switch, a 3-phase overcurrent transformer to protect from electrical surges, a crankcase heater to protect from refrigerate loss when the compressor is not active, protection against excessive superheat/discharge gas temperatures which fatigue components and lead to inefficient operation of the system, and a timer relay system to prevent the compressor from restarting too quickly.

– High-performance evaporator for indoor units

The evaporator creates high static pressure and smooth airflow while using minimal power featuring an adjustable motor pulley for a wide range of fan speeds.

– Integrated & simple controls

Settings can be adjusted (e.g. remote control, auto-restart after power outages, etc) during installation to confirm to specific needs, while the electronic control and display function on the indoor unit includes temperature, wind speed and timer settings.
