Hitachi VRF Systems
Advanced VRF Solutions for Every Project
Every building has different cooling demands. Different spaces, operating hours, occupancy levels and load profiles require an HVAC system that can respond accordingly.
ERATEC delivers Hitachi VRF systems engineered to provide flexible cooling, efficient operation and reliable performance across commercial, residential and specialized applications.
As an authorized Hitachi VRF distributor, we combine advanced Japanese technology with local engineering expertise to deliver the right system for every project.
What Is a VRF System?
Variable Refrigerant Flow (VRF) technology allows a single system to serve multiple indoor zones while adjusting refrigerant flow according to the actual cooling demand.
Instead of operating every space at the same output, VRF systems respond to changing loads across different zones.
The result is greater flexibility in system design, better control over individual spaces and more efficient operation under partial-load conditions.
Why Hitachi VRF?
Energy-Efficient Operation
Cooling demand rarely stays constant throughout the day.
Hitachi VRF technology adjusts system output according to actual demand, helping reduce unnecessary energy consumption while maintaining the required indoor conditions.
Flexible Zoning
Different spaces require different levels of cooling.
VRF technology allows multiple zones to operate according to their individual requirements, making it suitable for buildings with varying occupancy patterns, operating hours and thermal loads.
A Solution for Different Project Scales
From smaller buildings to larger commercial applications, the Hitachi VRF range provides different system configurations and capacities to match project requirements.
System selection can be based on building size, available power supply, cooling demand, space constraints and operational requirements.
Multiple Indoor Unit Options
One system does not mean one indoor-unit design.
Hitachi VRF systems support a wide range of indoor unit configurations, including:
1-Way, 2-Way and 4-Way Cassettes
Compact Cassettes
Silent-Iconic 4-Way Cassette
Wall-Mounted Units
Ducted Units
Ceiling-Suspended Units
Floor-Ceiling Convertible Units
Floor-Concealed Units
This flexibility allows the HVAC design to work with the architecture of each space rather than against it.
Hitachi VRF Product Range
air 365 Max
A VRF solution developed for projects with demanding cooling requirements.
air365 Max combines high-performance operation with the flexibility required for large and complex applications, allowing the system to respond to changing loads across multiple zones.
air365 Max — Cooling Only
A dedicated VRF solution for projects where cooling is the primary HVAC requirement.
Designed to respond to variable cooling loads while maintaining efficient operation across different zones and operating conditions.
air365 Mini
VRF technology designed for small and medium-sized applications.
air365 Mini brings the flexibility and advantages of VRF to projects where building scale, available space or electrical infrastructure may require a more compact solution.
Selected configurations can deliver up to 8HP using a single-phase power supply, expanding the possibilities for VRF applications.
Indoor Units Designed Around the Space
The performance of a VRF system is not defined by the outdoor unit alone.
Indoor unit selection affects air distribution, comfort, architectural integration and the overall experience of the space.
Hitachi provides multiple indoor unit options to accommodate different ceiling conditions, interior concepts and project requirements.
Silent-Iconic 4-Way Cassette
A ceiling cassette developed for spaces where HVAC performance and interior design are equally important.
Its distinctive design allows the air-conditioning system to become an integrated architectural element rather than simply another technical component.
Wall-Mounted Units
A flexible option for projects where wall-mounted installation is preferred.
Selected Hitachi wall-mounted units are available with capacities up to 4HP, allowing higher capacity from a single indoor unit in suitable applications.
Ducted & Concealed Solutions
For projects where HVAC equipment needs to remain visually discreet, ducted and concealed configurations allow the system to integrate with the architectural design while delivering conditioned air throughout the space.
Smarter Control
Effective HVAC operation depends on more than cooling capacity.
Hitachi control solutions allow users and facility teams to manage system operation according to the requirements of the building.
Available solutions include the Advanced-Color Controller and Eco-Compact Controller, while airCloud Tap supports commissioning of compatible air365 Max outdoor and indoor units.
Applications
Hitachi VRF systems can be configured for a wide range of building types, including:
Offices
Flexible zoning for spaces with different occupancy patterns and operating schedules.
Residential Buildings
Individual comfort and efficient operation across different areas of the building.
Restaurants & Hospitality
Cooling that responds to variable occupancy and changing operating loads.
Commercial Buildings
Scalable configurations for projects with multiple zones and different cooling requirements.
Industrial & Specialized Facilities
Engineering-driven solutions for projects with demanding operating conditions.
Technology Is Only Part of the Solution
Selecting the right VRF equipment is only the beginning.
System performance depends on correct load calculations, equipment selection, piping design, indoor unit configuration, controls, installation and commissioning.
ERATEC provides the engineering expertise required to turn Hitachi technology into a complete HVAC solution designed around the actual requirements of the project.
From System Selection to After-Sales Support
ERATEC supports the project throughout the HVAC lifecycle:
Engineering & System Selection
Evaluating project requirements and selecting the appropriate VRF configuration.
Design Support
Supporting load calculations, system configuration and indoor unit selection.
Supply & Installation
