Frequently Asked Questions (FAQs)
WHAT IS FAR INFRA RED TECHNOLOGY?
Imagine being in the sun on a cold day. The warmth seems to penetrate your body. The air temperature may be zero but you remain warm at least until the sun goes in! That’s Far Infra Red. Compare that to being in a warm room where it’s the air that keeps you warm. Keis technology is designed to deliver Far Infra Red reliably, effectively and efficiently as possible.
HOW IS THE HEAT PRODUCED?
Fine yet incredibly rugged micro alloy fibre elements strategically placed within the garments provide a lightweight, flexible Far Infra Red source with a long service life with extreme comfort.
HOW ARE THE GARMENTS POWERED?
There are two ranges of Keis garments. ‘Dual Power’ garments that can be powered from portable Lithium-Ion (Li-Ion) Batteries or an external power source such as a vehicle battery. Higher powered garments require an external 12v source such as a vehicle or stand-alone battery.
WHAT IS ‘DUAL POWER’?
Many Keis garments can be powered both from a 12v source, such as a vehicle battery, or from 12V Li-Ion battery packs. We call these our ‘Dual-Power’ products. ‘Dual-Power’ products have the advantage of being used anywhere and by managing multiple battery packs it’s possible to remain warm for long periods in any situation.
WHAT IS ‘MANAGE YOUR FUSES’?
Safety at Keis is paramount so we have introduced a strict Fuse Management System that we call ‘Manage your Fuses. All garments and accessories come complete with appropriate fusing or fuse pack and full instructions to guide you through this simple process.
WILL MY MOTORCYCLE BE ABLE TO POWER THEM?
Most larger motorcycles will power any number of garments, for example jacket, trousers and gloves without difficulty. However for smaller bikes running a number of garments you should take the advice of your dealer or contact us directly providing details of the motorcycle and the garments involved.
HOW LONG DO THE PORTABLE LI-ION BATTERY PACKS LAST?
This depends entirely on the number of the garments powered, the power setting used and the battery condition. As a general guide take the battery capacity in mAh and divide by 1000. For example a 2200mAh battery is expressed as being 2.2 Ah. Then take the consumption of the garment and divide this into the battery capacity. If the garment draws 1A then the battery should last around 2.2 hours. Remember that generally the controllers cut consumption by 33% on medium and 66% on low so this will extend battery life accordingly.
WHY CAN’T I USE PORTABLE LITHIUM ION (LI-ION) BATTERY PACKS WITH ALL KEIS GARMENTS?
You can but they will only last a very short time and therefore would not be practical. For example a 2200mAh battery running our X25 Jacket at full power would last around 15 minutes!
HOW CAN I CONNECT MY KEIS GARMENTS TO AN EXTERNAL POWER SOURCE SUCH AS A VEHICLE BATTERY?
All Keis garments come complete with a fused supply lead designed to be connected across a 12v vehicle battery. Cigarette lighter and Optimate lead adaptors are available for vehicles so equipped.
In addition our ‘Dual Power’ products can be powered using optional Li-Ion Battery Packs that can be charged from the mains or vehicle.
IS THERE AN EASY WAY TO CONNECT TO MY BATTERY, WHICH IS BURIED UNDER MY FUEL TANK ON MY MOTORCYCLE?
There are two optional connectors available: A cigarette lighter type plug as available on some machines or an Optimate (Ket or SAE) plug that can be connected to any pre-existing Optimate connector.
DO YOU DO AN EXTENSION LEAD SO THAT I CAN HAVE MY CONTROLLER IN AN OUTSIDE POCKET OR TANK BAG?
There are both 300mm and 600mm extension leads that can be connected in series if necessary to provide a variety of solutions.
AM I LIKELY TO DAMAGE ANYTHING IF I WALK AWAY FROM AN EXTERNAL POWER SOURCE WITHOUT UNPLUGGING FIRST?
All Keis garments are fitted with friction connectors that pull apart when sufficient force is applied. No damage should occur when this force is applied.
CAN YOU CONTROL THE HEAT?
An optional Heat Controller is available. Some gloves have integral Heat Controllers. Remember not to use two controllers to control one garment – It won’t work!
CAN I POWER MORE THAN ONE KEIS GARMENT FROM ONE POWER SOURCE?
Yes, for example our Bodywarmers have built in sockets to power gloves (optional leads required) and insoles. Be aware that when using battery packs the period of operation is reduced as more garments are connected.
CAN I WASH MY KEIS GARMENTS?
One of the advantages of Keis technology is that they can be hand washed. Simply remove the battery packs, controllers and accessory leads and follow the care instructions that came with the garment.
WHAT TEMPERATURE CAN I EXPECT FROM MY KEIS GARMENTS?
Different garments work at different temperatures. Remember too that our Dual Power Bodywarmers are designed more to maintain the right balance between the heat generated by the body and heat loss to the environment. They are not designed to feel hot! Our Hi-Power garments on the other hand will almost always benefit from the use of the optional controller to provide optimum comfort.
CAN I GET SPARE PARTS?
Sure, simply ask your dealer or contact us directly.
