MTD-ERV 350 Methods of Operation

The MTD-ERV 350 has been designed and produced as a system for controlled ventilation of residential buildings. It comprises two air ßows that hygienically exchange their energy.

áPolluted air is drawn off by the exhaust air fan (A) from, for example, the kitchen, toilet and shower (B).

áThe heat exchanger (C) absorbs the heat from the exhaust air.

áThe supply air fan (D) draws in fresh air from outside (E).

áThe heat exchanger (C) heats up the intaken air using the heat absorbed from the exhaust air.

áIf a moisture exchanger is installed (option), moisture is also transferred from the exhaust air to the sup- ply air (for further information, see section 2.1.6).

áThe heated fresh air is delivered into the living rooms and bedrooms (F).

áThe now cooled polluted air from the kitchen, bathroom and toilet is discharged into the atmosphere (G).

áThe bypass (H) allows the exhaust air to be discharged to the atmosphere without passing through the heat exchanger so that no heat is transferred to the fresh air (for further information, see section 2.1.3).

áThe preheater (I) (option) ensures preheating of outside air so that balanced ventilation with heat recov- ery is assured even with moderate to severe frost (up to 150 m³/h at -15¡ C) (for further information, see section 3.4.2).

áThe post-heater (J) (option) additionally heats the supply air (after it has already been heated in the heat exchanger) before it is delivered into the living rooms (for further information, see section 3.4.3).

The balanced ventilation system contributes to energy saving, a healthy room climate and an optimum living climate and prevents problems with moisture.

3.4. Additional Options

Only for MTD-ERV 350 Luxury versions, with the exception of the preheater that can be installed in any MTD- ERV 350.

Please refer to the identification plate on the top of the MTD-ERV 350 to determine whether you have a basic or luxury version of the system.

These are external devices that can be connected to the MTD-ERV 350 Luxury versions (preheater also to Basic versions).

3.4.1. Preheater in MTD-ERV 350

All MTD-ERV 350 systems with “VV” in the device name (see identification plate on the top of the MTD-ERV

350)are equipped as standard with a preheater. All other MTD-ERV 350 versions can be equipped with a pre- heater as an option.

The preheater is a heating element that is in- stalled in the outside air duct of the MTD-ERV 350 just upline of the heat exchanger. The preheater heats the cold outside air before it reaches the heat exchanger in the event of moderate to se- vere frost. In this way the heat exchanger is pro- tected against freezing in addition to the standard frost protection system.

The advantage of the preheater compared with the standard frost protection system is that balanced ventilation can be maintained even in the event of frost. In the event of a frost risk, the intake of out-

ERV 350, ERV 365 specifications

The MTD ERV 365 and ERV 350 are advanced energy recovery ventilation (ERV) systems designed to enhance indoor air quality and energy efficiency in residential and commercial buildings. These units utilize cutting-edge technologies to transfer heat and moisture between incoming and outgoing air streams, optimizing the temperature and humidity levels of the conditioned air.

One of the main features of the MTD ERV 365 is its high energy recovery efficiency. Equipped with a specially designed heat exchanger, this ERV can reclaim a significant portion of the energy from the exhaust air, reducing the heating and cooling load on HVAC systems. This results in lower energy bills and decreased environmental impact. The ERV 350 offers similar benefits but is tailored for slightly smaller spaces, making it suitable for various residential applications.

Both models are constructed with durability in mind, featuring robust housing and weather-resistant materials that ensure long-lasting performance. The MTD ERV series is designed to withstand varying environmental conditions, ensuring reliable operation in challenging climates.
