  circuit 1: +80°C to +240°C
  circuit 2: -20°C to +80°C
• Limescale free heat exchanger
• No cracking of the oil thanks to special heating construction
• All parts in contact with water are made of stainless steel or bronze
• Unit on castors

Safety devices

• Level control for dry run protection
• Expansion vessel with safety shut-off in case of overflow
• Electronic temperature limitation and monitoring in the controller
• Mechanical safety thermostats
• Visual and acoustic fault indications
• Integrated circuit breakers
• Main switch, transformer and motor protection switch

Controller

• Standard controller MP-888: The MP-888 is a digital temperature controller that ensures precise temperature regulation. It displays the current and target temperature, monitors the circulation of the tempering medium, and triggers an alarm in case of flow rate drop. The digital temperature controller can be operated in °F or °C and features analogue interfaces 0-5 V, 0-10 V, and 4-20 mA as standard.
• Digital interface controller MP-988: The digital interface controller MP-988 is designed for the interfaces RS-485, RS-232, Current Loop 20 mA, CAN-bus, Profibus, and Profinet. These interfaces are freely accessible without additional card inserts. Also included are a temperature differential display and over 30 integrated machine protocols.
