ThermoDual®
Domestic hot water charging system for hospitals, hotels, restaurants, sport centres as well as industrial buildings and dwelling houses
Application
ThermoDual® is a compact and effective domestic hot water (DHW) charging system. It optimally combines the system of storage water heater and instantaneous water heating system. The ThermoDual® system is suitable for hospitals, hotels, restaurants, sport centres as well as industrial buildings and dwelling houses, where the constant DHW temperature even during peak consumption periods is needed. ThermoDual® can be supplied from local and district heating systems, low-temperature or condensing boilers, boiler systems as well as solar, process and waste heat systems. The system is available in two different types with integrated DHW storage tank and integrated brazed (–S) or gasketed (–GS) plate heat exchanger.
Domestic hot water (DHW)
The ThermoDual® system can be delivered with self-acting or electronic controller for controlling of the charging
temperature and the temperature in DHW storage tank. It ensures the constant DHW flow and temperature even during peak consumption periods. The system operates in three operation modes: a load low operation, a peak load operation and a charging operation (no consumption).
Domestic hot water circulation
ThermoDual® is supplied with connection for DHW circulation. The connection pipe of DHW circulation is placed directly on the storage tank or in the cold water side (between storage tank and heat exchanger).
Options
The system can be combined with a second or multiple DHW storage tanks for optimum tailoring to on-site conditions.
Construction
The DHW storage tank and plate heat exchanger are made of stainless steel. The ThermoDual® system is de-
