Airstream–C

First conceived in 1983, EcoAir Box’s Airstream – C range (formerly the CSR2 Range) is a low carbon solution providing a healthy environment for commercial swimming pools and leisure centres.

The outstanding efficiency of these units allows up to 90% heat recovery from the plate heat exchanger. This reduces the top up heating requirement, lowering carbon emissions, capital & running costs.     

High levels of temperature and humidity control are managed by an intelligent control system to ensure interstitial condensation does not form within the structural envelope. This is critical as the nature of the chemicals present in a pool environment can cause structural failure.

To bring down running costs of the units, advanced fan speed regulation allows fan power to reduce by up to 80% as the de-humidification load lessens at times of low occupancy and overnight.

Utilising our composite plate heat exchanger rather than an aluminium plate heat exchanger minimizes the unit weight whilst improving corrosion resistance. All installed plate heat exchangers are backed up by our lifetime guarantee against corrosion.

Intelligent Control System

The unit is be supplied with a control panel fitted with a programmable logic controller.

The control panel shall include:

  • Door interlocked isolator
  • Terminals for main power supply
  • Motor and control components
  • Safety circuits


All necessary components for motor control and protection including fuses and overloads.

Air Volume Regulation

Air Volumes shall be automatically adjusted to ensure that the pool hall remains under a constant negative pressure during the occupied period.

The fan motor speeds shall be automatically adjusted in order to maintain the programmed air volumes during different modes of operation or when the filters become progressively dirtier.
