Overview

GMCAIR Dehumidifier Air Handling Unit is the special unit designed to provide extreme moisture removal from surface evaporation in indoor swimming pools and optimum comfort throughout the pool year round. Relative humidity above 60% causes not only harm to the comfort conditions but also causes condensation and damages on the walls, windows and all installations in the area.

Dehumidifier Air Handling Unit power stations are packaged type air conditioner units designed to ensure the highest comfort conditions within the pool area and to eliminate high absolute humidity where necessary. As the Dehumidifier Air Handling Unit is built up with a cooling group, an electric control panel and programmable automatic control equipment, which do not require any additional control units, you can use as just ‘PLUG IN & PUSH THE BUTTON!’

Body

All of the GMCAIR dehumidifiers use specially drawn aluminum profiles and double-skinned 45 mm thick, insulated panels in the body construction. The outer faces of the panels are RAL9002 pre-painted sheet and the inner surfaces are made of RAL9002 electrostatic poeder paint on galvanised sheet metal. Panels are connected to the profiles by means of snap-fasteners and double-component sealing seals are placed between the panel and the profile, thus providing the highest level of airtightness. Hinged doors are used on the cabin to control and maintain elements such as filter, heating and cooling battery, heat pipe and ventilator, and observation windows are used to visually inspect the fans. Depending on the customer's request or the size of the device, the device can be made in multiple pieces.

Ventilator and Aspirator Units

GMCAIR 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 imbued panel 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 130oC) 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.
