It serves as the hydraulic base for integrating a separately selected 400 V electric heating cartridge with 9.0 kW into the heating circuit.\u003c\/p\u003e\u003cp\u003eThe module is suitable for additional heating of heating water in systems with an existing primary heat source, for example with solid fuel boilers, water-bearing fireplace stoves, gas or oil boilers, as well as heat pumps. Typical areas of application are supplementary heating, frost protection support, emergency heat, or the use of surplus PV electricity via a suitable electric heating cartridge.\u003c\/p\u003e\u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e\u003cp\u003eThe GEMA MDC PLUS 400 base module consists of a steel tank with raw steel on the inside and a powder-coated surface on the outside. Thermal insulation is provided by 50 mm polyurethane foam; the outer cladding is made of plastic with a lid made of ABS plastic.\u003c\/p\u003e\u003cp\u003eFor hydraulic integration, the module has connection nozzles with female thread G 1 1\/4\u0026quot;. The receptacle for the electric heating cartridge is designed as a female thread G 1 1\/2\u0026quot;. For the MDC PLUS 400, a 400 V heating cartridge with 9.0 kW is intended; the heating cartridge must be selected separately and is not included in the scope of delivery for this item.\u003c\/p\u003e\u003ch2\u003eEveryday Benefits\u003c\/h2\u003e\u003cp\u003eThe base module enables a clear separation between the heating module and the heating cartridge. This allows the suitable 9.0 kW heating cartridge to be selected specifically according to the system concept, electrical design, and intended purpose.\u003c\/p\u003e\u003cp\u003eDuring operation, the module can provide support as an additional heat source when heating water in the heating circuit is to be electrically reheated. The specific function, temperature control, and electrical wiring depend on the heating cartridge used and the professionally installed system control.\u003c\/p\u003e\u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe GEMA MDC PLUS 400 base module is intended for open or closed central heating systems with appropriate safety devices. Water or a glycol mixture suitable for heating systems up to a maximum concentration of 50% is permitted as the medium.\u003c\/p\u003e\u003cp\u003eIt is integrated in a parallel heating circuit on the flow or return of the main heat source. For proper operation, a functioning safety valve and an additional circulation pump must be planned to ensure the required minimum flow rate of the separately installed heating cartridge.\u003c\/p\u003e\u003ch2\u003eTechnical data at a glance\u003c\/h2\u003e\u003cp\u003eThe following information refers to the GEMA MDC PLUS 400 base module without the supplied heating element.\u003c\/p\u003e\u003cp\u003eSuitable heating cartridge 400 V, 9.0 kW, to be selected separately Connection size female thread G 1 1\/4\u0026quot; Heating cartridge connection female thread G 1 1\/2\u0026quot; Device length 850 mm Max. operating pressure 10 bar \/ 1.0 MPa Max. operating temperature 90 °C Minimum flow rate at 9.0 kW 514 l\/h Material steel tank, inside raw steel, outside powder-coated Insulation 50 mm polyurethane foam\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eInstallation, hydraulic integration, and electrical connection of the separately installed heating cartridge must be carried out by qualified specialists. The module is integrated into the parallel heating circuit of the main heat source; when routing the pipes, ensure complete filling and reliable venting.\u003c\/p\u003e\u003cp\u003eThe MDC PLUS 400 can be operated horizontally or vertically according to the German manufacturer\u0026#39;s documentation. The final installation position must be checked against the currently supplied original documentation before installation.\u003c\/p\u003e\u003ch2\u003eNotes\u003c\/h2\u003e\u003cp\u003eThis item describes exclusively the GEMA MDC PLUS 400 base module without heating element. For this version, a suitable 400 V heating cartridge with 9.0 kW is intended. Smaller 400 V heating cartridges with 3.0 kW, 4.5 kW, or 6.0 kW belong to the MDC 400 logic and should not be assigned to this base module.\u003c\/p\u003e\u003cp\u003eOperation without water is not permitted. The electrical supply to the heating cartridge used may only be connected after the system has been filled and vented. The safety valve, circulation pump, fuse protection, cable cross-section, and control connection must be designed on site to suit the system and the selected heating cartridge.\u003c\/p\u003e\u003ch2\u003eScope of delivery\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\u003cp\u003eGEMA MDC PLUS 400 base module \/ heating module basic body without heating element\u003c\/p\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Gema GmbH","offers":[{"title":"Default Title","offer_id":47098442875228,"sku":"MDC400P","price":165.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/7796\/6428\/files\/gema-shop-mdc-plus-400-heizmodul_15eeb622-e7cf-47ec-95e1-7608194aab6c.jpg?v=1787558856","url":"https:\/\/gemashop.de\/en\/products\/gema-mdc-plus-400-basismodul-heizmodul-ohne-heizstab","provider":"GEMA Shop","version":"1.0","type":"link"}
