Product Features:

VENTAS Air Handling Units are produced with an air flow range of 1000m3/h to 100000m3/h.

Air Handling Units for Hygienic Applications (HY-AHU)

Internal surfaces of hygenic air handling units is coated with stainless steel sheet. anti-bacterial silicone is applied to the bottom surface for water imperviousness. Base height is designed to cover all type of the syphon conditions.

In hygenic air handling units, coils are manufactured as epoxy coated and with copper header. Coil’s case and sled systems are made out of stainless steel sheet.

In order to prevent water accumulation at cell’s connection areas, the units are connected with special connectors and then coated with stainless steel sheet such that a flat surface is obtained. In order to enable any kind of washing within the units and prevent any water accumulation and air leakage, special discharging system with siphon is employed in production by default. Moreover, for directly monitoring and controlling the inside of air handling unit during operation, there are placed several monitoring windows, waterproof and airproof lightings.

In order to meet the requirements from fans during process correctly, fans are chosen to be backward inclined with seldom wings and such that they can be easily disinfected. Plug fan applications are preffered more often since it enables air flow measurements and accurate setting.

Panels and Outer Cage System

For application areas such as hospitals (operation and clean room), pharmaceuticals factories, chemical production plants, food production factories, VENTAS Hygienic Air Handling Units are offered.

For panel production material, VENTAS provides galvanized, rustproof, aluminium and PVC coated sheet options. Moreover, the color of Outer skin sheet metal of units is RAL 9002.

Special aluminium profiles are used at the outer cage of air handling units. Profiles have a custom and closed design in order to reduce the internal pressure losses as much as possible and prevent from pollution that can be produced within the devices.

Corner and omega parts connecting outer cage system are designed appropriate with the structure of profiles and strengtheners and manufactured out of heat-resistant glass-strengthened composite material.

Panels are manufactured in sandwich structure with double sides. Within panels, rock wool insulation material with 70kg/m3 density is used as sound and heat insulation filling material. At connection points of panels and outer cage, impermeable tight seals from RPDM material with custom surface design, are used.

Within VENTAS Air Handling Units, air adjustment dampers with aerodynamic type blades  are used which works with hidden geared impulsion system. Damper wings and frame are manufactured from aluminium profile; moreover, gear system and bearing systems are produced with a hard material resistant to heat, dust, and strong against external hits. There are special air tight seals between damper blades in order to guarantee air imperviousness. 

Ventilator and Aspirator Units

VENTAS air handling unit's ventilator or aspirator units are produced in standard chamber structure. While ventilator and aspirators can be chosen as forward or backward curved blades, radial single/double suction fans balanced statically and/or dynamically, they can also be designed with plug-fan. Electrical motor of fans are montaged on to the same chassis. In order to prevent the vibration that can be occured especially within this chamber, to the other part of the air handling unit, rubber or spring type vibration isolator is used at an amount and size dependent on the capacity, size, fan and motor cycles of the unit.

Belt and Pulleys

Pulleys used in fans and motors are V-belt pulleys appropriate to DIN 2211 and TS 148 norms. Pulleys are formed in two parts. Since, after the first part is mounted in fabric to the fan and motor spindle, the second part can be mounted without a need for a hardware, pulley size can be made very easily upon need.

In order to transfer power between motor and fan pulleys, narrow V-belts (appropriate to TS 198/40 DIN 7753/1) or classical V-belts (appropriate to TS 198/1 DIN 2215) are used. Moreover, there is a belt stretching mechanism for adjusting the belt tightness between the fan and motor to the desired and efficient level.

Filters

Montage frames are designed for different filter classes used together with air handling units for several different purposes. Thanks to this design, filters can be placed very easily into their sockets with spring systems. Moreover, with this design, any possible by-pass that can be occured at filters are reduced to minimal levels. G3-G4 class filters used as front-side filters, have galvanized frames, and with galvanized string connections, they are installed with increased resistance to air flow.

Bag filters with different classes are used as second-level filters in air handling units. Besides, they are used as first-level filters for hygienic air handling units. Bag filters can be chosen out of F5 to F9 classes. In air handling units, rigid filters can be used as the last filter at between classes F5 to F9 upon need. In order to filter undesired odor, active carbon filters both with carbon panels or with cartridge, can be used.

Coils

Heater and cooler coils used in air handling units are manufactured as aluminium fin / steel pipe or steel fin / steel pipe depending on fluid features.

All coils are  subject to hydrostatic tests before installation. In order for easy maintenance and montaging, special sliding mechanism is designed. In air handling units with cooling coils, rustproof condensation pan and polypropylene drop holder (appropriate to DIN 7728 standards and resistant up to 130^oC) is used in standard.

Humidifier

Steam and liquid evaporating humidifier units can be produced upon request in standard cell structure. In order to prevent water drops, that formed during humidification within the cell, to get over to the surrounding or to the other parts of the unit, polypropylene water drop eliminators are used and installed to the inner part of the cell.

Silencer

Silencer modules are manufactured in standard cell structure. Rock wool or glass wool is used in silencers. Different numbers of columns can be used within the cell depending on sound attenuation features   with respect to capacity and size.
