Casing
Patented ISOSTREAM® modular system with wall panels of thickness 45 mm, which are made of galvanized steel sheet with external coating in shade RAL9002 (gray-white). The panels are filled with sound and heat insulation from non-flammable mineral wool. To facilitate service, the Casing of the unit is equipped with an openable door with locks. The round sockets are equipped with a rubber seal, the square sockets are ready to fit a damping insert with 20 mm frame. The frame of the unit is made of aluminum proils, the wall panels are screwed to the frame. The condensate outlets from the heat exchanger and cooler are always located in the bottom panel of the unit and are ready for connection of an anti-odor siphon. At the customer's request, the casing of the unit can be provided with atypical surface protection with higher corrosion resistance.
Fans
The fan with backward curved blades is mounted on the inlet and outlet side of the unit. The impeller is made of composite material and is statically and dynamically balanced.
Motors
EC motor is mounted directly on the fan impeller. The fan motor can be continuously controlled by an external signal 0–10 V. The motor is equipped with its own built-in thermal protection. Motor efficiency class IE4, electric motor protection IP54.
Exchangers
The unit is equipped with a water or electric air heater, depending on the version. For the needs of summer air cooling, a water cooler or a direct evaporator is installed. For the needs of bivalence heating, the evaporator can be manufactured in a reversible design. The evaporators are designed as standard for R410A and R32 refrigerant. Water heaters and coolers have copper pipes and aluminum fins in a galvanized steel frame as standard. For the needs of higher corrosion protection, it is possible to provide the exchangers with additional anti-corrosion protection. Electric heaters have smooth heating rods as standard and are equipped with an operating thermostat with start temperature 60°C and emergency thermostat with manual reset and start temperature 120°C.
Recuperator
The recuperation counterflow heat exchanger with fully separated supply and exhaust air flows is made from aluminium. It includes a bypass with a damper that fully controls the air supply to the exchanger or to the bypass. On request, the recuperator can be equipped with a circulation or mixing damper (marked C or MX in the unit code).
Filters
For sizes 500, 1000, 1500, 2200 and 3600, there are 96 mm thick F7 and M5 filter filters on the air supply and exhaust. For sizes 5100, 6000, 7800, it is possible to place 2 filter cassette cells of different classes of 48 mm thickness or 1 filter element of 96 mm thickness for supply air intake and exhaust air intake. Filters are available in classes from G4 to F9. Access to the filters is via the inspection door on the operating side of the unit. The unit can be supplemented with MFL filter cartridges with MFR filter inserts in the case of multi-stage filtration.
Dampers
Aluminium control dampers prepared for the installation of the servo-drive are integrated on the supply air intake and exhausted air intake. The dampers meet tightness class 2 according to EN1751. On request, the unit can be retrofitted with dampers in tightness class 3.
Electrical connection
The supply voltage 1x230V / 50Hz or 3x400V / 50Hz depends on the equipment of the unit. Supply cables, cables to sensors and power cables to the fans are fed to the unit through plastic bushings in the unit wall. Rubber grommets are prepared inside the unit for cable routing with membrane.
