Apricus pool heating solar energy commercial application pressurized Evacuated tube &heat pipes solar water heater

Evacuated Tube Collectors combine the high efficiency performance of evacuated tubes with rapid heat transfer capacity of heat pipes to provide a collector that can operate efficiently in almost any climate providing hot water for residential or commercial solar water heating projects.

Apricus ETC evacuated tube solar collectors are available in 10, 20, 22 & 30 tube sizes (Some models may not be available in your local market).
