Itho - HRU ECO 4

This high efficiency MVHR unit is ideal for all new build dwellings, especially those being built to a higher standard of air-tightness.

The HRU ECO 4 is a high efficiency heat recovery unit. It has a sophisticated counter-flow heat exchanger which can recover up to 91% of the heat from the discharge air. This recovered heat is used to pre-heat the fresh air being brought in from outside.

StecaGrid 2000+

The Steca DualString product range consists of Masters and Slaves. Like the Slaves, the master includes an inverter, but it also provides additional functions: a four-line display, a data logger for storing the yield values, country-specific grid monitoring of the alter- nating current output, and optional use of an inter- face card.

The StecaGrid 2000+ uses the DualString concept. This means that every inverter (Master or Slave) has two inputs, with each input having its own MPP tracker. One module string can be connected to each input. If required, the inputs can also be connected in parallel.
The advantage of such a system is the low sensitivity to negative influences such as (e.g.) partial shadowing, functional faults, or the dropout of a string. The use of several decentralized MasterSlave combinations reduces the cost of DC cabling, and minimises electrical losses.
