Lochinvar Corp. and TiSUN have joined forces to bring new solar thermal systems to the commercial market in the United States, Canada, and Mexico. This collaboration provides solar thermal panels specifically engineered and designed for commercial use, solar thermal storage tanks, pumping stations used to control, and move the solar energy throughout the system, as well as a wide array of system accessories.

The Lochinvar/TiSUN solar thermal system line includes two options for solar thermal panels. The Commercial Solar Flat Panel Collector (SCH models) is a high-efficiency solar thermal panel featuring PVD coating, a laser-welded absorber, and a serpentine heat coil design, which allows for optimum heat transfer in a forced circulation solar system. This versatile, single-piece collector is designed for both on-roof and freestanding installations and is available in sizes ranging from 65 to 130 sq ft.

The other solar thermal panel option available in the Lochinvar/TiSUN line is the Light Duty Commercial Solar Collector. Designed to withstand harsh outdoor conditions and provide years of service under the sun, the Light Duty Commercial Solar Collectors are easy to install in either a vertical (SLV models) or horizontal (SLH models) position. Like the SCH models, these collectors also feature a serpentine heat transfer system and a laser-welded absorber with PVD coating.         

The Lochinvar/TiSUN thermal panels are equipped with an aluminum frame structure with powder coat finish for a long service life. In addition, all models are SRCC-OG100 certified and offered with a 10-yer limited warranty. The Lochinvar/TiSUN Commercial Solar Pump Station is an all-in-one solar pumping package, complete with a Differential Solar Control that offers eight different system capabilities and Btu metering. Available in three sizes, the pump station is designed to provide adequate flow through up to 1,000 sq ft of collector area. The unit features a variable speed pump, flow meter, air separator, flush and fill valves, safety group, and EPP two-piece installation.

The Commercial Solar Pump Station constantly monitors the collector and tank temperature; as the tank temperature cools below set-point and the difference between the two temperatures reaches a field adjustable differential-point, the control starts the circulation pump. If the variable speed pump feature is utilized, the differential control adjusts the speed of the pump to achieve the highest temperature difference between the collector and the tank. This large temperature difference harvests the solar heat in the most efficient manner possible. When the constant flow feature is used, the pump operates at a steady speed until the tank reaches its desired temperature or there is no longer a sufficient difference between the collector and the tank temperature to heat the tank.
