Flight simulator Ventilation and air conditioning system Flight simulator Ventilation and air conditioning system

Never miss a day of operation

With One Fits All Compressor Unit

With SimV+AC, never miss a day of operation due to faulty air conditioning
Simvac SRB

Since SimV+AC carries out flight simulator ventilation and air-conditioning system research, development, testing, and manufacturing, we can modify an existing unit to suit your simulators’ needs. Moreover, depending on potential, a unit can be designed from A to Z according to your needs.

The Flight Simulator Ventilation and Air-Conditioning System include, two AC units in a single package for redundancy, automatic switchover in case of a failure of one unit, integrated smoke generator option, almost zero downtime unit, dependable in its design and packed in a redundant system & so much more!

This backup system will take over in addition to informing you of the nature of the problem of the defective part.

Simvac SR Ventilation System

Ventilation System

EC Backward inclined blowers; 2 blowers if fast smoke extract option selected, 1 blower if no fast smoke extract option (continuously closed loop)

Each blower is controlled in constant static pressure mode at +3.5"H2O for supply and -3.5"H2O for return. Blowers are constantly "ON" when the unit is powered.

Smoke extract option includes 3x blade dampers with Belimo motors and HEPA filter for "dirty" air discharge. Fresh air inlet port and dirty air discharge port are added on unit.

Return and supply air ports are 12" dia. Designed for easy attachment of flexible ducts adapted for full-flight simulator requirements.

Refrigeration System

Variable speed Mitshubishi BLDC compressor. 36 000Btu/Hr max cooling capacity.

Carel Drive for compressor speed control

Electronic expansion valve from Carel

Simvac's proprietary advanced heatpump electronic control with Flight Sim specific firmware

No freeze system thanks to Calorek's electronic control. The compressor speed is modulated in order to avoid freezing the coil no matter what airflow is passing through it.

Choice of water-cooled or external condenser unit.

If water-cooled, an external fluid cooler is available as an option. It includes the Fluid Pump, Fluid Cooler (Exchanger Coil and Fan), Expansion Tank and Feeder in a single unit for warm climates and two units for sub-zero climates.

If a condenser unit option is chosen, customers need a qualified technician to connect the HVAC unit to the condenser unit. The HVAC unit will be precharged with the correct amount of refrigerant for 25' length lines to the condenser unit. Additional refrigerant may be needed for longer linesets. Service valves provided.

DB9 connector provided for Thermostat connection ("Y", "C", and "R" terminals)

Simvac SR Refrigiration System
Simvac SR Smoke Generation System

Integrated Smoke Generated Option

Look Solutions Viper NT smoke generator in dedicated compartment. Easy access for servicing (fluid filling).

Smoke pusher blower included in same compartment

2" inner diameter smoke piping and fitting concentric in return air port

DB9 connector provided for "Smoke Gen ON" (Input), "Smoke Gen Ready" (Output), "Smoke Gen Smoke Go" (Input)

Maintenance Software

Labview-based maintenance software can be provided. Used for diagnosis of the machine and air pressure adjustments as per application needs. Easy-to-use interface. Connect via USB with any laptop.
