Overview

Overview

Save space & cool silently with the compact Kahn Sentinel 2 Climate Control System.

It's tiny – around half the size of similar systems. And it's quiet - even the outdoor unit won't vibrate.

  • Cools & heats areas of up to 4 x 600W lights
  • Cheap to run on normal household supply
  • Easy to install - no engineer needed!

Installation's easy! You can fit them, shut them down & move them about yourself! You won’t need an engineer or any special tools. 

It's been trialed and tested in a hostile environment - it works. 


    

Suitable for
Kahn Sentinel 2 - 4kW up to 4 x 600W grow lights
Kahn Reaper 2 - 8kW up to 8 x 600W grow lights
Kahn Atom - 12kW up to 14 x 600W grow lights
Kahn Little Boy  - 18kW up to 24 x 600W grow lights

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.

Cheap to Run!

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

Auto Day & Night Modes

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

For consistently high yields all year round, plants need stable, optimum growing conditions.


Your temperature is key to this. The ideal temperature depends on what you’re growing, but as a rule of thumb, it’ll generally be 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 Sentinel is the ideal unit for up to 4 x 600W light set ups. It’ll keep your area cool, using hardly any power. If your system’s bigger than this, consider choosing a larger size.

Why is it so simple to install?


Unlike other systems, Kahn Climates have a unique built in refrigerant gas recovery system.


You can install, move or even take your units for a service without specialist tools or an engineer.


With most a/c systems you need to connect them with a vac pump to remove air & moisture from connecting pipes. If you don’t, 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!


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.

Q & A

Questions and Answers (2)

Does the Khan sentinel climate control system outside box really need to be outside the house or just outside the grow tent?
The outdoor unit does need to be outside in order for the Kahn Sentinel to function correctly.

If I need a longer connection between the two units indoor/outdoor can I extend the 1meter connection?
The unit is supplied with a 3 metre connector between the indoor & outdoor parts, it is possible to extend this with a further 3 metre connector.
