Typhoon propane vapour gas burning heaters are of stainless steel and chrome

construction with a sturdy steel box section mounting frame designed to give

many years of trouble free service.

Each heater is adjustable and can

be raised or lowered to direct the

heat into the fan inlet to suit single

or multiple fan applications. The

control panel is detachable and

can be mounted either side of the

unit or in other positions in the fan

house.

The controls give a digital readout

of humidity or temperature

depending on the purpose it is

being used for, grain drying, onion

drying or frost protection.

MODULATING HEATER

When using the TKG burner to dry grain the fan should be run continuously until

the grain is at 18% moisture content, 12% for Rape, from then on run the fan with

the burner switched on.

Set TKG relative humidity setting to obtain a 2% lower than the actual material

moisture content. I.E. Barley moisture content 18% set to 16% = 75% R.H. (See

chart below).

Check material moisture content regularly. Reduce R.H. setting to keep a 2%

lower than actual moisture content.

When desired grain/material moisture content is attained, operate FAN ONLY

with TKG in off position until grain is cooled.

In this way the minimum use of heat is required and the maximum use of

ambient air reduces overall drying costs.
