CASING

All sections consist of casings constructed according to the same basic principle with frame profiles and insulated panels. In general, great emphasis is placed everywhere on accessibility and ease of service.

PROFILES

The frame profiles are made of aluminium. This ensures both high strength and a high degree of corrosion resistance. The frames are assembled with insert corners and have softly rounded edges.

PANELS

The panels are made of aluzinc and are insulated with 50 mm mineral wool, which ensures both good thermal insulation and good sound attenuation (external noise).

The side panels are attached to the frame profile with screws. End, top, and bottom panels are fixed internally with screws and then sealed.

DROPLET SEPARATOR AND DRIP TRAY

CW and DX coils as well as IC/ICC cooling module are equipped with a drip tray and a removable droplet separator. The drip tray is positioned for easy cleaning.

INSPECTION DOORS

The doors open 180° and provide easy access for inspection and service. The doors are tightly sealed and constructed according to the same principle as the panels, but fitted with sealing strips.

Choose between:

• Sturdy handles that are easy to operate and have built-in locks
• Locks for special keys

The hinges are adjustable and fitted to the rear edge of the doors for maximum mounting strength.

OUTDOOR UNITS

The units can be supplied in a special outdoor version with roof and weather-protective discharge grilles. They can also be equipped with intake boxes for air intake.

VDI 6022

Developed in accordance with the German hygiene standard VDI 6022.

EXHAUSTO OFFERS THREE DELIVERY OPTIONS:

The units are supplied ready-assembled and Exhausto ensures that all modules are correctly connected and assembled on a base frame.

The modules are delivered separately, an advantage if they have to be transported inside the building. For this reason,VEX4000 has been specially designed for ease of assembly.

The unit is delivered as a SPLIT version, where the unit is delivered unassembled as a flat pack. This means that even large units can be transported through small doors and then assembled on site. The SPLIT solution is more expensive, since specially trained EXHAUSTO technicians are required.

• Patented automatic leakage control (ALC™) prevents transfer of exhaust air and prevents the recirculation of airborne particles and gases, including viral particles.
• Selection of filters and pre-filter to guarantee air quality
• Choice of integrated cooling
• Integrated switch,
• EXcon 100% Plug & Play control:
  • Constant airflow,
  • Constant pressure,
  • Patented adaptive pressure regulation
  • Variable airflow with CO2/VOC sensor (0–10 V signal),
  • Regulated pressure: optimal pressure regulation is used to adapt the pressure setpoint according to the measured airflow, ensuring energy efficiency,
  • Temperature control,
  • Integrated clock: operating hours can be controlled with timer.
• BMS communication protocols:
  • Integrated webserver - TCP/IP RJ45,
  • Modbus RTU RS485,
  • BACnet TCP/IP,
  • LON (optional).
• Version without automatic control system also available,
• Developed in accordance with the German Hygiene Standard VDI6022.

INTEGRATED CONTROL SYSTEM

EXcon supports the following networks:

Integrated webserver - TCP/IP

Modbus - RS485 / TCP/IP

BACnet - TCP/IP

EXcon is based on BUS technology, with multiple external communications facilities. All control can be performed from a central unit via the web server.

EXHAUSTO offers special solutions for areas which require specific control facilities, e.g. shops which need precise temperature control, special cooling control and humidified areas.
