Fan Coils
Polar air by Siwa fan coils are all rated to AHR440, conform to CSA standards and are ETL listed. Because these units offer a wide range of capabilities and customizations, these fan coils are your one stop shop for all hydronic (HW + CW) fan coils.
Horizontal - Ducted
The PDWA horizontal FCU are one of the most versatile fan coil units out there so they’re quite in demand.
Heights start from 7.8″ up to 16″ and they can handle ESP’s up to 1.25″.
Up to 3,000 CFM
Horizontal AHU - Ducted
Siwa’s PDWB ducted horizontal air handling fan coils is designed for strength and high capacities. They can handle ESP’s up to 1.75″ because of their powerful blowers.
Up to 5,000 CFM
Console FCU
Siwa’s console can be wall mounted, floor mounted, ceiling exposed or even recessed in the wall.
9.8″ x 19.5″
Slim Console FCU
Siwa’s slim console can be wall/floor mounted, ceiling exposed or even recessed in the wall.
Being only 5.1″ thin, this is the thinnest console in the world so is great for small rooms or stringent architectural requirements.
5.1″ x 22.5″
Ceiling 4-way
Cassette FCU
Siwa’s cassette FCU is recessed into the ceiling.
It is excellent distributor of 360° heating and cooling around a large area because of it’s 4 way automatic louvres
Ceiling 1-way
Slim Cassette FCU
Siwa’s slim cassette is recessed into the ceiling and given it’s slim nature, it is ideal for a limited ceiling space given its 7″ depth.
High Wall FCU
PHW
This highwall unit is perfect for buildings with limited ceiling space or a design that requires zone by zone control of climate.
They’re easy to install so they’re great for retrofits.
Vertical AHU
MVAHU/VAHU
Finally, this is a unique type of hydronic air handler.
Because this unit is floor mounted and has high static capabilities, it can be ducted from a mechanical room to large or many areas.
Up to 1.75″ ESP & 5,000 CFM
EC Motors
In terms of motor technology, 100% of our hydronic fan coils use EC Motors.
Firstly, EC motors are highly energy efficient, consuming less electricity compared to PSC motors. They also offer precise speed control, allowing for optimal airflow and temperature regulation. Additionally, EC motors operate quietly, reducing noise levels in the space. Moreover, they have a longer lifespan and require minimal maintenance, resulting in cost savings over time. In conclusion, hydronic fan coils with EC motors offer compatibility, energy efficiency, and enhanced performance in various system designs.
Diversity
Siwa’s fan coil selection operate fully on hot water and chilled water.
Furthermore, they are designed to provide comfortable heat at low water temperatures and is an excellent source of cooling even at high temperatures.
Finally, Siwa’s fan coils are compatible with water-water geothermal heat pumps, condensing boilers, standard chiller system or any water based system.
