Meet the Kahn Atom Climate Control System - it’ll blow you away!

Use it to cool & heat areas with up to 14 x 600W lights almost silently - even the outdoor unit won’t vibrate!

  • Cools & heats areas of up to 14 x 600W lights
  • Cheap to run on normal household supply
  • Easy to install - no engineer needed!

Units are light & compact to save space. And they feature super strong, flexible rubber pipes so you can move units about with ease.

You can install yours without an engineer, and run it off a normal household electrical supply – it doesn’t get easier than this.

Only 4oC Difference

Any air released by your outdoor unit is no more than 4oC hotter than the outside temperature, (as long as the outside temperature is + 3oC or higher). This feature is over-ridden if your grow room temperature goes off target and needs cooling quickly.

Auto Day & Night Modes

No water is needed. To lower energy use further, your Kahn Sentinel will simply ‘tick over’ once your target temperature is reached.

More Cooling, Less Power, Lower Pressure

Your system automatically switches between Day & Night mode when lights go on and off. If there’s a power loss, your system will auto-restart & recognise what mode it needs to be in.

More Cooling, Less Power, Lower Pressure

Your system uses an azeotropic refrigerant mix that leads to more cooling, using less power, under a lower pressure. It's so good at cooling, your system is super compact, too!

Easy to Install – No Engineer Needed!

You can fit it yourself. You don’t need an engineer, vacuum pump or any specialist tools! The indoor unit’s so light that you could lift it with one hand. 

Easy to Shutdown, Restart & Relocate

If you need to move your system, it’ll safely shutdown & restart at the click of a switch. You can thank the built in refrigerant gas recovery system for that.

NASA Standard Pipes!

Forget the rigid copper pipes - units are connected with a strong, flexible rubber pipe. It won’t bend, snap or kinkThe same hosing is used space stations.

Compact & Space Saving

They’re tiny! We’re talking around half the size of other similar systems.

The Science

To keep your yields high yields all year round, you need to create stable, optimum growing conditions.

Part of this involves controlling your temperature. For best results, keep it roughly between: 

• 24oC and 28oC (during the day/lights on)
• 22oC and 23oC (during the night/lights off)

To ensure you stay inside this range, you need a heater in winter, and air con unit during the summer.

The Kahn Atom will cool areas with up to 12 - 14 x 600W light set ups using hardly any power. If your system’s bigger than this, consider choosing a larger size.

Why is it so simple to install?

With most a/c systems you need an engineer to remove air & moisture from connecting pipes using a vac pump. If you don’t do this, ice will form – this ice will keep chipping away at the internal components until your system inevitably fails. Your system may work, but only for a few weeks – probably 10 at most!

Kahn Climates are different. They have a unique built in refrigerant gas recovery system.You can install, move or even take your units for a service without any specialist tools or an engineer.

Azeotropic Refrigerant

Your system uses an azeotropic refrigerant mix that leads to more cooling, using less power. Overall, the COP (coefficient of performance) is up to 6.8, to keep your running costs low!

Because the cooling capabilities are so much higher, your system is super compact - you can use it in much tighter spaces!

Using azeotropic refrigerant also puts less pressure on your system internally.

How to Use

You can fit your system without using an engineer or any specialist equipment.

Complete instructions are supplied with your kit.
