Supply or supply-and-exhaust
A supply unit delivers treated outdoor air. A supply-and-exhaust unit combines air supply and extraction; the project may include heat recovery.
Climate control equipment
AHU ventilation units
The central unit filters and treats air, supplying it to rooms through a network of ducts.

Central air treatment for buildings
An AHU is a unit that draws in outdoor air, cleans it with filters and, when necessary, heats or cools it, or regulates its humidity. The conditioned air is supplied to rooms through ducts, while stale air is removed by the exhaust system. These units are used in offices, retail and sports facilities, hotels, healthcare and educational institutions, warehouses, and manufacturing facilities.
Design and placement
The unit configuration is determined by the facility's needs
Filters and fans, as well as heat exchangers for heating or cooling, are installed inside the casing or in separate sections. Depending on the project, the configuration may include a heat recovery unit, humidification or dehumidification sections, and controls.
The unit can be installed in a plant room, on the roof, or outside the building. The design must account for access for maintenance and filter replacement, noise and the need for sound insulation, ductwork, and controls; for outdoor installation, the load-bearing capacity of the structures must also be considered.
For different types of buildings
Central ventilation helps organize air supply and treatment in rooms with different operating schedules.
- 01Offices and retail facilitiesFor administrative buildings, shopping centers, and stores where it is important to provide air exchange for visitors and staff.
- 02Warehouses and manufacturingFor logistics complexes and manufacturing facilities with air exchange and supply air treatment requirements.
- 03Public buildingsFor sports facilities, hotels, hospitals, and educational institutions, taking into account the purpose of the rooms and how they are used.

Configuration options
Choose the unit type based on the project
AHUs differ in how they organize air exchange, their design, and their heating or cooling method. The required sections are determined by the facility's needs.
Compact or modular
A compact solution is supplied as a ready-made unit. A modular unit is assembled from sections to meet the required configuration.
Water or electric heating
Depending on the available building services, water heat exchangers or electric heating are used. A heat recovery unit can recover heat or cooling from the exhaust air.
How a ventilation unit works
The equipment treats the airflow in a sequence determined by its configuration and the project requirements.
- 01Air intake
Outdoor air and, where included in the project design, recirculated air enter the unit.
- 02Filtration
Air passes through filters that capture dust and other contaminants.
- 03Treatment
Heat exchangers heat or cool the airflow; additional sections can regulate humidity, while a heat recovery unit can transfer heat or cooling from the exhaust air.
- 04Supply and extraction
The conditioned air is delivered to rooms through ducts, while stale air is extracted. The controls operate the unit according to the set parameters.
Project-specific selection
Prepare your facility's input data
For equipment selection, it is important to consider the purpose of the rooms, required air exchange, number of occupants, heat gains, filtration requirements, and available building services.
- It is also helpful to share the proposed installation location, ductwork details, noise level requirements, and whether the controls need to be integrated with the building management system.
Practical features of AHUs
A single unit combines air treatment components and can be configured to meet the needs of the building.
Multiple functions in one unit
Air filtration, supply, and treatment are combined in one casing or a set of sections.
Project-specific configuration
The equipment configuration is selected based on filtration, heating, cooling, and other operating requirements.
Heat recovery option
If a heat recovery unit is installed, heat or cooling from the exhaust air can be transferred to the supply airflow.
Automatic control
The controls maintain the set parameters and can be integrated with the building's BMS.
Installation in a plant area
The unit can be installed in a plant room, on the roof, or outdoors, if the project allows.
Factory-ready supply
Compact units are supplied as ready-made assemblies, while modular configurations are built from sections.
Project support
Support at every stage of implementation
Klimatrade works with professional partners, design organizations, and installation companies, helping with equipment selection and technical questions.
- Technical consultations, assistance for designers and engineers, preparation of technical and commercial proposals, and technical support are available. Equipment is supplied from warehouses in Almaty and Shymkent; warranty service is provided through service partners.
Ventilation units for facilities in Kazakhstan
Selecting an AHU ventilation unit for a facility in Kazakhstan starts with calculating the required air exchange and clarifying temperature, humidity, and filtration requirements. The selection takes into account the purpose of the rooms, number of occupants, heat gains, available building services, and installation location. For projects in Almaty, Astana, Shymkent, and other cities, Klimatrade specialists can help identify the right configuration, prepare a technical and commercial proposal, and provide support with technical questions. The cost and equipment configuration depend on the project parameters and selected package.
Frequently asked questions about ventilation units
What is an AHU?
An AHU (Air Handling Unit) is a ventilation unit that filters and treats air before supplying it to rooms.
Where can an AHU be installed?
The equipment is usually installed in a plant room, on the roof, or outside the building. The location is chosen based on the project, the unit's dimensions, and service access requirements.
Can the unit operate in winter?
Yes, if the configuration provides for heating the supply air. This can be done using water or electric heating, as well as heat recovery.
Is a separate exhaust system required?
It depends on the facility's ventilation design. A supply-and-exhaust AHU combines air supply and extraction, while a supply-only unit operates alongside a separately arranged exhaust system.
How do you determine the right capacity?
Selection is based on air exchange and heat gain calculations, taking into account the number of occupants, the purpose of the rooms, and air treatment requirements.
Can the controls be connected to a BMS?
Modern units can be equipped with controls and integrated with the building management system. The feasibility and scope of integration are determined for each project.
What affects delivery times?
Delivery times depend on the series and configuration: compact models may be available from stock, while modular units are configured to order. Current availability and terms can be confirmed upon request.
