SECTION 3: OPERATING PRINCIPLE

The Airstation is designed to create optimal operating conditions for a compressed air system. It protects your equipment from the weather conditions, filters the air, distributes electricity to all its devices, and connects the equipments to a single compressed air outlet.

TEMPERATURE CONTROL

The louvers are sized to allow sufficient fresh air intake from the outside, exhaust hot air from the compressor to the outside, and recover heat inside the enclosure. Air circulation is ensured by the compressor's fan(s).

It is important to note that the louvers operate only when the compressor(s) is/are running. An interlock auxiliary contact is factory-installed in the compressor's electrical panel.

Control of all louvers is provided by a single dedicated thermostat, with a single signal sent to all louver actuators.

Types of louvers:

  • Wall-mounted fresh air intake louvers;
  • Wall-mounted hot air exhaust louvers (connected to the ventilation duct);
  • Hot air recovery louvers (on the ventilation duct).

When the Compressor(s) is/are not running, the louvers are in their initial position. This means that the wall-mounted intake and exhaust louvers are fully closed (NC), and the heat recovery louvers on the ventilation duct are fully open (NO).

When the Compressor(s) is/are running and the temperature inside the station is below the thermostat setpoint, the recovery louvers are open, and the wall-mounted louvers are closed.

Notes: The degree of closure and opening of the louvers depends on the level of difference between the ambient temperature and the setpoint temperature to be reached. The greater the difference, the more open the recovery louvers are and the more closed the wall-mounted louvers are.

When the Compressor(s) is/are running and the ambient temperature is above the setpoint, the recovery louvers close, and the wall-mounted louvers open.

Notes: The degree of closure and opening of the louvers depends on the level of difference between the ambient temperature and the setpoint temperature to be reached. The greater the difference, the more closed the recovery louvers are and the more open the wall-mounted louvers are.

The system is modulating and is directly proportional to the temperature difference between the ambient temperature and the temperature set on the thermostat.

Figure 2 shows a control unit labeled A350PS-1C.

Some AWA Airstations are equipped with one or more extraction fans, controlled by a dedicated thermostat.

Figure 3 shows a control unit labeled A421, and an associated ventilation grille.

Auxiliary Heating Units

Some AWA Airstations are equipped with one or more auxiliary heating units to maintain the indoor temperature above freezing point when the compressor(s) is/are not running. The auxiliary heating unit(s) is/are controlled by a dedicated thermostat.

Figure 4 shows a thermostat unit.

This same heating system is interlocked with the compressor(s) to prevent them from running unnecessarily at the same time.

Electrical System

In most AWA Airstations, a custom-designed main electrical panel is installed. This panel powers and protects the equipment and accessories inside the station: lights, thermostat, louvers, fan, automatic drain, and heating unit.

The station requires a single voltage input to the main panel. This panel transforms and distributes specific secondary voltages to the various electrical devices.

The electrical system has been designed to prevent the risk of electrocution during the proper use of the station. Each equipment and appliance is individually grounded. Leakage current is thus evacuated in case of insulation failure.

The main electrical panel of an AWA Airstation contains several disconnect switches. The number of switches varies depending on the different configurations.

Single Compressor System:

  • One isolating switch for accessories;
  • One isolating switch for compressor.
  • For models with a dryer on an independent circuit, the panel will be equipped with an additional switch.

Multiple Compressor System:

  • One main switch.
  • One switch for accessories.
  • One switch for each compressor.
  • For models with a dryer on an independent circuit, the panel will be equipped with an additional switch.

The accessory switch primarily powers the heating unit, lighting, ventilation system, service outlet, as well as some low-consumption devices such as nitrogen generators, desiccant or refrigerated dryers.

Wiring Diagrams:

Each Airstation have their own electrical schematic provided.

Piping System

Compressed Air

The piping network at the compressor outlet distributes compressed air to various devices according to the user's needs.

Isolation valves are strategically positioned to isolate the equipment from each other.

Generally, the system has a single air outlet, but there may be multiple outlets depending on the user's requirements.

Condensate

Purge valves on equipped devices are connected to the piping network for condensate drainage.

Some AWA Airstations include oil/water separators in their piping networks.

Condensate or water filtered by the separators is then directed to the condensate discharge point.

WARNING: Condensate drainage from compressors, dryers, and filters may contain oil or other contaminants.
