Murickens Group is an ISO-certified producer and international provider of solar water heating techniques. In Kerala, there are two types of solar water heaters that are frequently used. The first is a maintenance-free FPC (Flat Plate Collector) model with practically all of its parts made of pure copper and properly guaranteed for long endurance, while the second is an ETC (Evacuated Tube Collector) type built of glass tubes. The fundamental difference between these two models is that the heat absorber (panel) in the FPC model is made of copper fins, but in the ETC model it is made of evacuated glass tubes. Murickens goods are sold under the registered brand name ‘MG’ through the MURICKENS marketing system. The MG water heater plays an important function.
