EDER SPIROTECH Multicontrol Compact Solo MCK-S500-4.0 usable upper working pressure 1.0-4.0bar – 0050905

multicontrol kompakt solo MCK-S for loss-free accommodation of expansion volume and for pressure maintenance in closed heating, ventilation, and cooling systems. Manufactured according to the construction guidelines of EN 12828. A sleek, self-contained unit in a self-supporting, sound-insulating design with an attached, unpressurized expansion tank (max. 0.5 bar), designed as a painted steel tank (100% of the volume usable). High-quality, double-flanged, replaceable tank membrane for optimal separation of system medium and atmosphere. Tank level measurement with two pressure transmitters on the tank flanges. Safety valve 0.5 bar for tank protection and a drain funnel pre-assembled ex works. Drain and sludge valve on the lower tank flange. Control unit as compact hydraulics with a low-noise pressure maintenance pump (1x100%) designed as a multi-stage centrifugal pump with high-quality mechanical seal, a pressure-proportional, continuously regulating, mechanically set overflow valve (1x100% of the expansion volume flow). Precision system pressure measurement. Hydraulic connections for on-site integration, made ex works on the right and with necessary shut-off valves (easily convertible to left). Temperature monitoring of the system medium entering the tank. Prepared connection point for easy installation of the refill module for quantity-controlled, liter-accurate refilling, also provided for retrofitting at any time. Water treatment (softening, demineralization) combinable with the refill module for standard-compliant top-up water. Electronic control in microprocessor version for controlling all processes, ergonomically arranged control panel with a well-thought-out operating concept in many national languages. Self-contained compact measurement and switching unit in a closed control cabinet design including connection cables. Already in the basic version, four potential-free alarm contacts (malfunction, warning, refilling in progress, device function enabled) as well as inputs for "ext. enable contact device function" and "external alarm". Prepared installation slots for additional expansion modules for extended signal exchange (also for retrofitting). Remote monitoring of the device also possible via various multicontrol bus modules or multicontrol web module (also prepared for retrofitting). Integrated, automatic economic low-pressure degassing function based on the principle of pressure relief as standard. Additionally, external temperature monitoring provided by an optional temperature sensor at the point of integration into the system. Max. system protection temperature: 110 degrees C (with pre-expansion vessel) Max. temperature at the connection point: 70 degrees C Max. operating pressure (PN): 10 bar
