Heat transfer systems ITHW with water - The universal systems up to 200 °C
LAUDA Heating and cooling systems from the line of heat transfer systems in the ITHW model series always consist of the electrical heating module, circulating pump, expansion tank and a maximum of one heat exchanger module (cooler). The systems can be equipped with a water, brine or air-cooled heat exchanger. If a cooling water network is available, the heat transfer fluid can be directly coupled. The heat exchanger and expansion tank are then omitted. The enclosed versions of the systems produce a temperature controlled liquid flow and are supplied as compact, completely insulated, ready-to-use systems with a control cabinet. They are fully tested at the factory.
Electrically heated temperature control systems with water as heat transfer fluid are preferably used when a consumer is to be heated or temperature controlled at medium operating temperatures and high heat transfer values. These systems are simple and quick to install and need only a slight amount of maintenance. Equipped with a cooler, a ready-to-use heating and cooling system is produced.
Water is the ideal heat transfer fluid in the medium temperature range. Water is economical, non-toxic, non-combustible and has very high thermal transfer values. This means that the areas for thermal transfer can be kept small. However, the risk of freezing, corrosion and the high vapor pressure (already 15 bar at 200 °C) must be considered during project engineering. Often additives such as glycol are used which also acts as a corrosion protection agent.
