BLAST

The enclosure of the BLAST unit is made of injection-molded, foamed polypropylene. The outer part of the enclosure is made of galvanized sheet steel, painted in RAL 9010.

 Specially designed control panel structure, including the internal geometry allowed to:

- Achieve very good thermal insulation,

- Eliminate thermal bridges,

- No risk of condensation on the walls of the unit,

- Reduce pressure losses in the air handling unit,

- Achieve very good sound insulation,

- Use of a four-sided, self-cleaning condensate drip tray,  

- Aesthetically pleasing, modern exterior.

Enclosure components can be easily disassembled to provide access to control panel components for ease of operation and service.

The control unit comes standard with a wall mounting bracket and feet in the Standard version. DECOR feet are available as an option.  

Energy-efficient direct-drive radial-axis fans with EC motors are used. With the use of a pressure transducer (optional), the function of maintaining constant volume and mass flow independently for supply and exhaust is possible.

The air handling unit utilizes a counterflow aluminum recovery exchanger with an automatic sealed bypass. The exchanger features high efficiency (up to 92%) and increased mechanical strength compared to plastic exchangers. It effectively separates supply and exhaust air streams. The exchanger is designed for easy disassembly for cleaning. It meets strict hygienic requirements. The heat exchangers used are certified according to Eurovent and VDI 6022.

Filters are disposable and replaceable. Special inspection panels for easy access to filters for filter replacement.

The BLAST air handling unit is standard equipped with ePM₁₀50% (M5) class filters. Optionally, an ePM₁60% (F7) filter can be used on the supply air.

The filters are made with mini-pleat technology, have a large filtration area, low resistance, increased dust absorption and therefore can have a longer service life.

The filtration system used effectively separates particulate matter, which is a component of the particulate matter of popular smog.

The BLAST air handling unit is equipped with an electric preheater, which has an antifreeze function. The power of the heater is continuously controlled by PWM signal. The heater is activated when the pressure drop across the recovery exchanger increases. At each stage of the exchanger's operation, the pressure control points are checked, so that in the event of fin frost, the electric heater is controlled according to the degree of frost. The applied defrosting system allows optimal use of the heater's operation and power, prevents the possibility of excessive frosting of the exchanger, which consequently affects the minimization of energy consumption costs.

The air handling unit is equipped as standard with a bypass, which is an automatically controlled system of tight, counter-rotating dampers. This solution makes it possible to realize the so-called free cooling function - free cooling of rooms with outside air. We can use free cooling, for example, in summer when the air temperature in the room is too high and the outside air is pleasantly cool.

The connection spigots are made of galvanized sheet steel with rubber gasket, diameter ø200mm. They are standard equipment of the air handling unit. They are attached to the air handling unit and their installation to the unit is done by the so-called push-in method. Appropriately profiled holes in the air handling unit and the seals used ensure a tight connection between the spigot and the air handling unit.

The BLAST air handling unit is designed to be connected to the ventilation system with spigots pointing upwards or sideways. For directional connection, use the appropriate elbow fittings with their own gaskets.

The BLAST control panel is equipped with an easily accessible connection panel where there is a socket for plugging in the power cable and a socket for connecting a communication cable with a STANDARD or ADVANCE control transmitter. The standard power cable is 2 meters long. It is terminated on one end with a plug for direct connection to the unit and is unarmored on the power source side.

The communication cable is 2 m long, terminated on one end with stripped wires, ready for connection to the referencing-unit, and on the other end with an RJ-12 connector. If it is necessary to install the referencing-unit at a greater distance from the unit, the cable can be extended to a maximum of 50 m for proper operation.

The BLAST control panel is supplied in Plug & Play standard.

The automation of the panel consists of the main board of the controller and the connection strip module, which allows the connection of optional automation components. For the power supply of the automation expansion elements, there are two reference voltage sources 230VAC and 24VDC on the power strip module board. The location of the terminal strip module allows for easy service access. Connecting and activating additional automation elements is simple, even convenient. The user obtains a product that allows the recuperation unit to be expanded with additional elements (even after installation) without having to replace the boards, the transducer or the application.
