Operational Information - FAQ's




What is it? 

TRANSCOOL IS A portable EVAPORATIVE AIR COOLER that can be used with 12 volt, 24 volt or 240 volt electrical systems.




How cold will the Transcool 12 volt - 24 volt air cooler make my cabin or room?

The Transcool is a small evaporative cooling unit that is totally portable.

Transcool is simply able to blow a cool breeze over the user whilst in front of the unit-

It  is a ‘personal spot cooler’ – delivering a cool breeze effectively at a range of up to 2-3 metres distance.

The Transcool will not cool down a ‘room’ to a controlled temperature,this is where a refrigerated unit is required.

Will the Transcool Portable air cooler cool my room or vehicle like a built in air conditioner?

Quite simply-No!

A refrigerated air conditioning system is hard to beat, but useless without 240v electricity!

A refrigerated air conditioning system has many complex and expensive components. These systems require many permanently fitted parts such as a compressor, condenser and evaporator, and refrigerant gas to cool air.  A vehicle or household air conditioner requires immense power to ‘drive’.

If you absolutely need a vehicle with air conditioner then repair or replace yours!

If these options are not possible, then Transcool will help provide relief from the heat.

Evaporative cooling performance can differ depending on various conditions such as ambient temperature and humidity, but test results show that Transcool can deliver air temperatures up to 45% cooler (at the vent) than the ambient air temperature just using water at room temperature!

Temperatures at up to 50% cooler than ambient (at the vent) can be achieved using ice water.

Test results taken on a 40o (C) day with humidty at 12% showed a vent temperature at 21o (C) using just water at room temperature !

For an example of effectiveness, think of a standard fan on a hot day.

The air streamed at you feels cooler,  even though the air is technically at ambient room temperature.

It feels 'cooler' because it is moving!

Transcool combines this factor ,along with cooled air from it's super effective evaporative cooling pad to provide you with crisp cool air that simply feels like- HEAVEN!



The following are brief examples of the differences between air conditioner and evaporative cooling:

 For maximum efficiency, you must allow proper ventilation when using an evaporative cooler and allow fresh air to the unit, where as you can re-circulate air cooled by an air conditioner in an enclosed environment. 

An air conditioner operating in an enclosed environment, can lead to air becoming ‘stale’. 

You must dispose of excess water accumulated by an air conditioner. There is no excess water accumulated by an evaporative cooler.

Condensation with use of Transcool is not an issue

Refrigerated air conditioning is much more expensive! 



How long will the water last?  

Water usage with evaporative cooling varies on fan speed and ambient air temperature.

Under most conditions Transcool's internal 1.8 litre supply will last all night on 'low' speed - adequate for cool air while you're sleeping!

The great news is that no damage will result if you run the Transcool out of water during use!

Transcool can be used without water in areas of high humidity, you can even add ice!

The EC3 is also supplied with an external 5 litre tank for extended periods of use. The clear external tank features an ON/OFF tap and connects to the unit via hose.

The Transcool EC3 uses an internal float system that automatically maintains the correct water level when using the external tank.

Using the external tank in conjunction with Transcool enables around 24 hrs of use.

Transcool features a transparent water window to display level.



How long will my battery last?

Transcool only uses a maximum of 1.7 amps per hour  (on high speed)

This equals hours of cooling comfort - even without your vehicle running

You will generally find 'low' fan speed (0.7amps) more than adequate for sleeping.

The EC3 is now fitted with LOW BATTERY VOLTAGE SHUT OFF protection reducing the risk of flat batteries




The following results were achieved using a standard 12 volt 60 Ah Lead acid car battery*, with Transcool running until battery voltage was reduced to 12 volts - this ensures reliable vehicle startup!

LOW SPEED -       42 hours

HIGH SPEED -      10 hours

*Battery power draw examples were recorded using a fully charged Delkor 22F-520 (12volt 60 Amp hour) car battery, running the Transcool EC3 constantly until battery voltage fell to 12 volts. (Battery was not connected to car at time) Individual results may vary on depending on battery specification.



How much noise?

The sound level produced by the Transcool Evaporative air cooler is even quieter than that of a car air conditioner/heater fan. This ranges from 46db (low fan speed) to 59db (maximum fan speed) at 1 metre. The tone Transcool produces is a relaxing, steady weary  drone’- perfect to help dilute any annoying outside noises. 

The Transcool evaporative air cooler can be used in nearly any environment and vehicle!

‘My Transcool arrived yesterday,a world post record !
It is a miracle that it was not stolen during one of our many post office strikes -Lucky you not to live in a banana country!
I tested it last night with normal tap water and boy it works.
I go on fishing trips with my motorhome to remote destinations with no 220v, so transcool will do the job 100% as a spot cooler.
Keep up the good work’
