Ventilation and Air Conditioning Automation

What we automate

• Supply and supply-and-exhaust air handling units (AHUs).
• Air conditioning and chiller-fan coil systems.
• Air curtains, smoke extraction, and air pressurization.
• Zonal indoor climate control.

Ventilation automation functions

• Maintaining the set supply air temperature.
• Water heating coil frost protection (critical for the Kazakhstan climate).
• Control of dampers, valves, the heat recovery unit, and actuators.
• Heating/cooling cascade, schedule-based and occupancy-based control.
• Monitoring of filter clogging and fan status.
• Alarm signaling and integration with fire automation.

System components

• Ventilation control cabinet with a controller and power section.
• Temperature, pressure, CO₂ sensors, and filter differential-pressure sensors.
• Variable frequency drives for fans to save energy.
• OVEN, Siemens, Schneider controllers or specialized ones (Carel).

Turnkey project stages

• Survey and collection of source data on the units.
• Design of the automation scheme.
• Assembly of the control cabinet and controller programming.
• Installation, commissioning, and tuning of operating modes.
• Connection to supervisory control and ongoing service.

What you get

• A comfortable and stable indoor climate without manual adjustment.
• Savings on heat and electricity (scheduling, variable-frequency control, heat recovery).
• Protection of the heating coil and equipment from failures.
• Remote monitoring of ventilation 24/7 via the Atlas server.

When ventilation needs automation

• It is stuffy or cold — the indoor climate is not held stable.
• There is a real risk of the water heating coil freezing in winter.
• Units run around the clock with no load, wasting heat and electricity.
• There is no unified control of several units at the facility.
• Correct interaction with fire automation is required.

Where the automation saves

Schedule-based and occupancy-based operation switches units off when they are not needed; heat recovery reclaims the warmth of the exhaust air; variable-frequency fan control delivers exactly the required air volume, and precise temperature regulation eliminates overheating. Together this noticeably reduces heat and electricity consumption without any loss of comfort.

Protecting the heating coil and equipment

In the Kazakhstan climate, frost protection of the water heating coil is mandatory: the automation monitors the return water and supply air temperatures and, when a threat arises, closes the damper, stops the fan, and opens the valve. Monitoring of filter clogging and fan status prevents failures and maintains the design airflow.

Standards and requirements

We deliver solutions in accordance with the Electrical Installation Code (EIC) and the requirements for ventilation and fire protection systems, including shutting down ventilation and controlling smoke protection upon a fire alarm signal.

Integration with Atlas supervisory control

We connect ventilation to the Atlas server and, where needed, combine it with heating and air conditioning into a single building management system (BMS): all units are visible and controlled from one system, with trends, alarms, and schedules.

Timelines and cost

Cost depends on the number and type of units and the set of functions; the timeline depends on project readiness and equipment delivery. After the survey we provide an estimate and schedule; phased modernization without shutting down the facility is possible.

Why Atlas Scada

• A full cycle from design to service.
• Experience modernizing ventilation at commercial facilities with a transition to OVEN equipment.
• Integration of ventilation into the building's overall supervisory control (BMS).
