Horizontal or vertical
A horizontal layout arranges the sections in sequence; a vertical layout may reduce the footprint if supported by the manufacturer.
Central ventilation
Supply air tailored to the building’s needs
The frame unit supplies outdoor air after filtration and the required temperature treatment.

How it works and where it is used
A frame-type supply air unit is an assembly with a load-bearing frame and insulated panels attached to it. The casing houses the sections needed to condition the air: filters, a heater, a cooler and a fan. Outdoor air enters through the air intake, receives the treatment specified in the project, and is delivered by the fan into the duct network. Extract air is removed by a separate exhaust system. The sections and their order are determined by the building’s needs, available utilities and installation conditions.
Design
Sections configured for the project
The unit is built around a load-bearing frame and insulated panels. Filters, a supply fan and the selected air-treatment sections are installed inside. A drain pan and condensate outlet are provided for the cooler, while service doors or removable panels allow access to components. The controls and additional components depend on the selected configuration.
The unit can be supplied as a single assembly or as separate sections for on-site installation. Selection takes into account the installation location, service access and equipment delivery requirements. For outdoor installation, the casing design and unit configuration are chosen to suit the climate conditions.
For buildings of different types
Frame-type supply air units are used in central ventilation systems. The equipment configuration is selected based on the required air exchange, air-treatment needs and the specifics of the site.

Configuration options
Choose the layout and air treatment
The frame unit configuration depends on the available space, operating conditions and required air treatment. The feasibility of a specific layout is confirmed during selection.
Indoor or outdoor
The casing configuration is selected for indoor or outdoor installation, taking operating conditions into account.
Filtration and temperature treatment
The unit may include filters, a heater and a cooler; the section types depend on project requirements and available heating and cooling sources.
Additional sections
Fine filtration, humidification, sound attenuation and other treatment components can be specified in the project.
Heating and cooling type
Options include water or electric heating, water cooling, or a direct-expansion cooler, subject to compatibility and engineering conditions.
How air moves through the unit
The treatment sequence depends on the unit configuration and project design. If included in the configuration, the controls operate the equipment and its safety functions.
- 01Outdoor air intake
Air enters through the intake and air damper.
- 02Filtration
The airflow passes through one or more filtration stages specified in the project.
- 03Treatment
The air is heated, cooled or otherwise treated by the sections included in the unit.
- 04Supply to the rooms
The supply fan delivers the conditioned air into the duct network.
Equipment selection
Start with your project data
Share the technical specification or key system parameters to help determine the appropriate section configuration and unit design.
- For selection, prepare the design airflow rate, duct system resistance, outdoor and required supply-air temperatures, heating and cooling medium parameters, filtration requirements, installation location and dimensional constraints.
Flexible configuration for your project
The frame design makes it possible to select a combination of sections and a unit configuration to suit the site’s needs and installation conditions.
Configuration tailored to site requirements
The unit can include the required stages of filtration, heating, cooling and additional treatment.
Choice of installation location
Indoor and outdoor configurations are available to suit operating conditions.
Section-by-section delivery
Separate parts of the unit can be supplied for on-site assembly if specified in the project.
Service access
Service doors and removable panels can provide access to the main components.
Integration capability
With suitable controls, the equipment can be integrated with the building management system.

Frame-type supply air units in Kazakhstan
Frame-type supply air units are used for central ventilation in commercial and industrial buildings. If you are planning to buy a frame-type supply air unit in Kazakhstan, selection starts with the design air exchange rate and air-treatment requirements. The frame-and-panel construction allows the required filtration, heating and cooling sections to be combined in one system. The price of a frame-type supply air unit depends on its configuration, including capacity, casing design, heat exchangers, filters and controls. The cost is therefore determined for each specific project. A unit for a shopping centre and equipment for an industrial facility may require different sections and installation conditions. For facilities in Almaty, Astana, Shymkent and other cities, climate conditions, the installation location and the availability of utilities are taken into account. Send the Klimatrade specialists your technical specification or key system parameters to discuss the configuration and delivery terms.
Frequently asked questions
How does a frame-type unit differ from a compact unit?
A frame-type unit generally offers more flexibility in choosing the section configuration and layout. Compact units more often have a predefined set of components. However, compactness and a frame-type design are not mutually exclusive.
Can the unit be installed outdoors?
Yes, if the unit has an outdoor configuration suited to the site’s climate conditions. A unit designed for a plant room should not automatically be assumed suitable for outdoor installation.
Does a supply air unit provide exhaust ventilation?
A supply air unit delivers air. Extract air is usually removed by a separate exhaust system; a supply-and-exhaust unit is selected when both functions need to be combined.
Can a water cooler be connected to a chiller?
Yes, if the unit is equipped with a water cooler compatible with the parameters of the chilled-water circuit. Suitable control valves and a condensate drain must also be provided.
Can the unit maintain a set humidity level?
This requires the appropriate treatment sections and controls. A configuration with only a filter, fan and heater cannot provide precise humidity control.
What affects the cost of the equipment?
The price depends on capacity, section configuration, casing design, fan and heat exchanger types, filters and control capabilities. The cost is calculated for the selected configuration.
