Advantages
Heating & Cooling
One of the highest certified capacities on the market with a heat/cool capacity of up to 15 kW.
Ideal for various applications, including healthcare and commercial spaces like hospitals, shopping malls, gyms and airport terminals.
Airflow
The 4-way air design means supply air covers the room evenly for uniform temperatures and fewer hot/cold spots.
Plus adjustable louvers (only available with I-Type Control), let you aim airflow to suit the room layout and avoid drafts on occupants.
Condensate
Integrated Sauermann pump with nominal 1200 mm (47") rated lift removes excess water efficiently to prevent leaks.
It also helps to control indoor air humidity, protects ceiling finishes, and keeps long-term maintenance to a minimum.
Sensitive Design
Slim, decorative panel casing in RAL 9010 integrates neatly into ceilings and suits a wide range of interiors.
Plus an optional G4 (MERV 8) filter upgrade captures finer particles, supporting cleaner air quality in environments that need it like healthcare.
Models
Includes both a 2-pipe and 4-pipe model, and available in 5 sizes to suit larger applications like hospitals.
The 4-pipe allows heating in one area and cooling in another simultaneously, ideal for buildings with varied thermal loads like north/south-facing zones or occupancy patterns.
Installation & Maintenance
Direct front panel access and valve connection with a "plug & play" control box makes installation easy.
Supplied ready to install, cutting time and cost, with internal/external drain pan, NBR insulation, integrated Sauermann condensate pump with 1200 mm (47") nominal rated lift, and G2 (MERV4) filter. With I-Type Control the Infrared Handset is also included.

FAQs: cassettes
What PCGH-3R cassette capacity is best for my space?
Determining the right capacity for your cassette fan coil unit is crucial for achieving optimal comfort and efficiency.
The best way to find the perfect fit for your space is by using Polar Air PASELECT software. This innovative tool helps users design their ideal HVAC system by calculating multiple configurations tailored to their specific needs.
How easy is it to install the PCGH-3R Cassette?
The PCGH-3R is offered as a complete package, including an internal/external drain pan, 5 mm (0.2”) NBR insulation, integrated Sauermann condensate pump, manual air vent + water purge valve and G2 (MERV 4) filter. Plus, there are compatible accessories also available.
Installing a cassette fan coil requires a suitable ceiling space with enough depth to house the unit. The process includes mounting the cassette securely, connecting it to the chilled/hot water supply and return lines, and ensuring proper condensate drainage with the integrated pump. Electrical wiring is connected to the control system, and the unit’s louvers and panel are fitted. Once installed, the system is pressure-tested, the airflow is balanced, and controls are configured.
Proper installation ensures efficient operation, easy access for servicing, and long-term reliability.
Do PCGH-3R Cassettes need maintenance?
Yes, cassette fan coil units require regular maintenance to ensure optimal performance and longevity. Routine maintenance tasks include cleaning or replacing the air filters, checking the condensate pump and drain for blockages, and inspecting the coil and fan for dust or debris buildup.
Regular maintenance helps prevent potential issues, improves energy efficiency, and ensures the unit operates effectively. It’s recommended to schedule professional maintenance at least once a year to keep your cassette fan coil unit in top condition and to address any minor problems before they become major issues.
What is a cassette fan coil?
A cassette fan coil is an HVAC unit mounted flush with the ceiling, leaving only the panel visible for a neat, space-saving design. It combines a fan and a water coil to circulate air, heating or cooling it before distributing it back into the room through one, two, three, or four outlets. This design provides efficient temperature control, even air circulation, and helps improve indoor air quality by filtering dust, odors, and excess moisture.
Cassette fan coils are widely used in healthcare, commercial, education, and office buildings for reliable comfort.
The PCGH-3R 4-Way Cassette fan coil units use hydronic (water-based) technology within the unit. Learn more about why Polar Air believes in hydronic systems here.
