Hung below the ceiling, it circulates the water from your loop through a standard header-type coil and blows 1,800 CFM of warmed air, at 1,000 FPM at the outlet. Sterling rates it at 78,400 BTU\/h with 200°F entering water, 60°F entering air and a 20°F drop.\u003c\/p\u003e\n\u003cp\u003eIn the HS series, it is the largest size with a motor under 1\/3 HP. This 1\/12 HP, 115 V motor is single speed; Sterling describes it as totally enclosed with thermal overload protection. The manufacturer also publishes a reduced-speed rating, 70,500 BTU\/h at 1,500 CFM. Since the standard motor has only one speed, we confirm with Sterling what that operation requires before planning it.\u003c\/p\u003e\n\u003ch3\u003eFor tall volumes: what we check\u003c\/h3\u003e\n\u003cp\u003eSchool bus garage, recreational vehicle showroom, distribution warehouse: in these buildings, warm air rises and collects under the roof. A 1,000 FPM jet helps bring it back toward the floor. Mounting height and air throw, however, are not in the data we verified. We establish them with Sterling’s installation manual, the free height and the position of the doors.\u003c\/p\u003e\n\u003cp\u003eThe second point is the water. The rating applies at 200°F; with cooler water, Sterling applies 0.857 at 180°F, 0.715 at 160°F, 0.571 at 140°F, 0.429 at 120°F and 0.286 at 100°F. We start from the temperature your electric boiler or air-to-water heat pump actually supplies. The unit needs 7.9 GPM with a 20°F drop, for a pressure drop of 0.36 ft H2O, and the loop can contain propylene glycol, with the correction factors published by the manufacturer.\u003c\/p\u003e\n\u003ch3\u003eA complete installation\u003c\/h3\u003e\n\u003cp\u003eOur technicians check the structure that will carry the unit, hang it by rods from the connections provided, properly level, and connect it to the loop with isolation valves and air purging. They make the 115 V electrical connection, install the control and start everything up while measuring the flow.\u003c\/p\u003e\n\u003cp\u003eAirGreen is a family business established in \u003cstrong\u003eMontreal\u003c\/strong\u003e for more than fifteen years.
