OF UNITS
CASING SKIN
» metal sheet thickness increased by 20% » increased rigidity and durability of the AHU structure
» low absorption of heat radiation and UV » increased resistance to weather conditions
FAN SECTION CAGE
» increased longitudinal stiffness of the structure
» easier sections assembly
FRAME
» easier transport » greater profile resistance to deflection
STRUCTURAL COLUMNS
» thermal breaks on the mullion as standard » high resistance to weather conditions and UV rays

VTS PATENTED PROPRIETARY
SOLUTION
INSPECTION PANELS EQUIPPED WITH THE OPEN / CLOSE SMART SYSTEM AND NEW PROTECTIVE CORNERS
» easy to use, enabling quick opening and closing of the inspection panel » smart hinge - prevents seal breaking when the panel is opened (VTS proprietary and patented solution) » improved ergonomics with an integrated handle and hinge function » reduced risk of panel damage
ALUMINIUM STRUCTURAL COLUMNS WITH AN ADDITIONAL SEALING FIN AND A THERMAL BREAK
» thermal breake as standard - ensures no condensation outside the AHU » the fin ensures labyrinth sealing - currently the most effective solution on the market, mainly used in laboratory equipment
» original solution consisting in the use of symmetrical channel tension filled with a sealing compound, which provides 100% tightness of the connection between the column and construction structure

FUNCTIONS
Dual methode of heating coil freeze protection (low limit thermostat on the air and water side) • • •Energy recovery systems frost protection (temperature sensor downstreem energy recovery section) • • •
Measurement and control of the constant air volume (CAV) • •Measurement and maintennance of air volume based on system required pressure (VAV) • •
Control of the concentration of carbon dioxide in the air • •Air humidity control • •Pre-heater control for extreme low temperatures (maximization of the energy recovery performance) •
CONTROLS
SOURCES OF HEATING/COOLING
» Primary heater
» Primary cooler
» The recovery (plate heat exchanger or a rotary exchanger, glycol system)
NEW RANGE OF CONTROLLERS
» Mixing box
» Primary heater (before recovery of heat), electric/water
» Reheat coil (mainly used for drying)
CO2
» automatic reduction of the amount of outside air (keeping the CO2 concentration below the set value)
» optimisation of consumption of heat and electricity
HUMIDITY CONTROL
» control over air humidifying - both evaporative and steam
» supports control the drying process
CONTROL OF VS21 – 150 BACKUP ENGINES
» adaptation to the special needs of the building
» protection in case of failure of the first engine
ELECTRIC HEATER CONTROL
» smooth control system that adjusts instantaneous power to the current demand
MIXING BOX CONTROL
» smooth control of the mixing box, external signal or as in the CO2 control function, etc.
» optimization of the ventilation air to save energy
NEW FEATURES
MEASUREMENT AND CONTROL OF THE CONSTANT AIR VOLUME
» adjustment of the preset constant air volume under changing flow resistance - compensation of changing internal resistance of the AHU (e.g. with varying degrees of air filter dirt, different setpoint of the mixing box, etc.)
» adjustment of the fan power to the current needs of the installation
» immediate readiness of the AHU to work with the required performance immediately after installation
CONSTANT PRESSURE CONTROL WITH VARIABLE AIR VOLUME
» control of constant, preset air pressure at variable volume (efficiency change is carried out through the air distribution system – e.g. VAV controllers)
MAIN and LX HMI
SMART HMI
REED SWITCH
» electronic stop of the motor when the panel is opened
FAN SAFETY BARRIER
» protection against fan in-operation
SAFETY OF USE
HANDLE OPEN PROTECTION
» increased safety against accidental opening of the fan section
