Adiabatic Coolers
The TCI adiabatic system is designed for use with either their air blast coolers or air cooled condensers where water outlet or refrigerant condensing temperatures are required to be lower than that of the prevailing summertime dry bulb temperatures.
The system is designed to pre-cool the air inlet stream into the heat exchange coils of flatbed and V-type units.
Increasing the relative humidity of the air lowers its temperature from dry bulb temperature to its reduced ‘effective air on’ temperature.
This can result in water outlet and refrigerant condensing temperatures as low as 5°C above the wet bulb temperature (e.g. 24°C in a 19°C wet bulb).
Whilst adiabatic systems, designed for air blast coolers and air cooled condensers, are not governed by the rules in the HSE L8 document (guide for control of legionella bacteria in water systems), it does specify that each system should be judged on its own merit.
Due to the numerous safety measures and failsafe mechanisms incorporated in the system TCI consider it to be the safest and most reliable on the market.
- UV system included as standard – please click here to see its effectiveness at killing legionella bacteria
- TCI’s enhanced smart relay control gives the following functions for a long and safe product life:
1. Minimum adiabatic usage in peak summer ambient temperatures only.
2. Auto-drain facility empties the system of water during prolonged periods where adiabatic usage is not required.
3. Adiabatic pre-purge facility flushes the system to drain prior to start / restart of adiabatic spraying.
4. On detection of a fault with the UV lamp the adiabatic system will be shut down and an alarm signal sent. The unit will continue as a dry cooler only until the fault is fixed and the system reset.
5. The inlet pressure to the adiabatic spray booster pump is monitored. Should the inlet pressure drop too low the adiabatic system will be shut down and an alarm signal sent. This ensures that the system operates within design parameters and reduces the possibility of damage to the pump.
