Dantherm Wall Mounted Mechanical Ventilation & Heat Recovery / MVHR Units: HCV Range
Overview
The HCV 300-400-460-500-700 residential wall mounted ventilation units are primarily designed for villas and apartments. They meet ventilation requirements of houses up to 450m2 or more, depending on national requirements and the actual pressure loss in the installation.
The units are supplied as packaged basic ventilation units complete with built-in control panel, and are delivered with all parts necessary for wall installation. A wide range of additional accessories are available.
The wall mounted mvhr residential ventilation units are fitted with highly efficient counter-flow heat exchangers, which are optimised to a high efficiency level, thus achieving a low power consumption (SPI value) for the entire unit.
Model range
The HCV 300 unit is perfect for concealed installation instead of in a 60 x 60cm cupboard module, e.g. in a modern utility room environment, where everything is hidden behind doors. All ducts are connected to the top of the unit. On the HCV 300 and HCV 400, it is also possible to connect the supply duct to the base if ducts are to run beneath the floor.
HCV 400 and HCV 460 fit into a standard 60 x 60cm cupboard module.
HCV 500 and HCV 700 are ideal for free wall installation with minimum 700mm space. A standard wall rail is supplied with all units.

Features
All HCV wall mounted mvhr units are equipped with easy-access filter slots behind the upper front cover. The control panel with LED light indicators is located in an opening in the front cover.
Cabinet
The HCV insulation is made of expanded polystyrene (EPS) components with a minimum wall thickness of 32mm. This allows the units to be placed in rooms with temperatures as low as +12°C.
The outer surface is made of 0.8mm Aluzinc powder-coated sheet metal and painted in RAL 9016. The HCV series complies with European fire safety requirements as specified in EN 13501 class E.
The leakage rate of the unit (internal and external) is <2% as specified in EN13141-7 leakage class A1.
Function
The unit ventilates residential homes by extracting the inside humid air, and replacing it with fresh outside air, which has been heated with the heat energy of the extracted air. This reduces energy consumption.
The air volume can be controlled by:
- Selecting a fixed fan speed from 0-4.
- Demand mode, in which a built in RH sensor continuously adjusts the fan speed depending on any immediate demand, determined by the humidity of the extracted air.
- Week timer program – the fan speed will increase or decrease according to an hourly time schedule, or specific demand.
When very humid inside air is extracted, the humidity will condensate inside the heat exchanger and be collected by the embedded drip tray. This water is drained from the unit through the enclosed hose and then disposed of in the nearest drainage.
Installation
After installation of the unit, ducts and condensate hose, the unit needs to be calibrated to the specific environment. Measurements of air volumes are carried out via built-in air pressure spigots. Appropriate initial adjustments are performed directly on the control panel or with Dantherm PC Tool.
An air flow diagram is present on the front cover, showing the pressure and air volumes the installer must use to calibrate the two air flows (see example opposite).
Maintenance
In general, the only regular maintenance required by the HCV residential ventilation units is to check/change the air filters twice a year when the alarm is triggered (flashing LED and acoustic alarm).
The user changes the filter by opening the filter cover, changing the filters and resetting the filter timer on the built-in control panel. Apart from changing the air filters and cleaning the outside of the unit, any other form of service will have to be carried out by qualified personnel.
Local Dantherm partners are always available with support to solve any problem that might arise with the unit.
Removing the front cover gives access to all types of service and repair.
