FRTT - Rooftop Air Handling Unit
The FRTT series is a fully self-contained rooftop packaged air conditioning unit that combines cooling, optional heating, ventilation, and fresh air supply in a single outdoor-mounted unit — eliminating the need for separate indoor plant rooms or air handling unit spaces. Using a direct expansion (DX) refrigerant system, the FRTT conditions and distributes air to the space below via ductwork, delivering high energy efficiency, fast installation, and low operating costs across large commercial buildings, airports, restaurants, and industrial facilities.
- We guarantee EU-standard quality.
- Count on rapid, reliable global delivery.
- Backed by 24 years of expertise.
Areas of Use
The FRTT series is the ideal solution for large commercial buildings and facilities that require a complete, self-contained HVAC solution installed on the roof — minimizing indoor equipment space requirements while delivering full heating, cooling, ventilation, and fresh air supply in a single integrated unit. Deploy these high-efficiency rooftop AHUs confidently in:
- Large commercial buildings, business centers, and corporate headquarters
- Airports, transportation hubs, and large logistics centers
- Restaurants, department stores, and retail shopping environments
- Cinema and theater halls, conference centers, and event venues
- Industrial buildings and facilities requiring compact, all-in-one HVAC solutions
Key Features & Specifications
All-in-One Rooftop Package Unit: The FRTT integrates cooling (DX coil), optional heating, ventilation, and fresh air supply into a single, fully self-contained rooftop unit — completely eliminating the need for a dedicated indoor plant room, indoor AHU, or separate refrigeration equipment. This dramatically reduces installation time, complexity, and total project cost.
Direct Expansion (DX) Refrigerant System: Cooling is achieved via a highly efficient direct expansion refrigerant circuit with a DX evaporator coil, delivering rapid, reliable cooling with excellent part-load efficiency. The DX system requires no chilled water plant, pipework, or pump sets — further simplifying the mechanical installation.
High Energy Efficiency & Low Operating Costs: Designed for high energy efficiency with a low initial investment cost, fast installation, and minimal ongoing operating expenses — making the FRTT series the most cost-effective HVAC solution for large commercial buildings in climates with significant cooling demands.
Complete Heating, Cooling & Ventilation in One Unit: The FRTT can cool in summer, optionally heat in winter, and continuously supply fresh outdoor air to the space below — meeting all year-round thermal comfort and indoor air quality requirements from a single rooftop installation point.
Outdoor-Rated Weatherproof Construction: Fully engineered for permanent outdoor installation on the roof, with weatherproof construction and UV-resistant finishes designed to withstand continuous exposure to rain, wind, solar radiation, and temperature extremes throughout the product lifetime.
Wide Capacity Range for Any Project Scale: Available in many capacity options to match the size and cooling load of the environment to be air conditioned — from medium-sized restaurants and retail spaces to large airports, conference halls, and industrial buildings requiring very high airflow capacity.
