Medium system and pressure system collector 
In response to the high pressure of medium circulation and pressure type solar hot water systems, the copper card sleeve connection of the collector is prone to detachment, and the liquid situation is affected. Meigrei has designed a copper outer wire joint for the collector, which uses stainless steel corrugated pipes for docking, stability, easy installation, and easy maintenance 
Collectors used in northern regions, 90mm+ultra thick frame 
In northern regions, the winter temperature is low and frost weather may occur, so medium circulation collectors are selected for the collectors. For low-temperature environments, Megaray has designed a seamless forming system for the back panel frame, reinforced EPDM sealing rings, and polyurethane foam to enhance the sealing and insulation performance of the collector, making the flat plate collector more suitable for use in northern regions.
