	Data is for general guidance only. Hitemp insulation refractories are meant for applications where high mechanical stability and insulating properties are required. Hitemp refractories are best suited for insulation of kilns and furnaces, both as hot face and back up linings. Hitemp refractories can be used for applications upto 1850 deg. The HB201, HB101bubble alumina range of insulating refractories is light weight, has good load bearing capacity and low heat capacity. They can be directly exposed to flame also.

Laboratory Furnace Parts

MUFFLES Muffles are mainly used in muffle furnaces where heating elements made out of kanthal / Nircrome wires wraped round the muffles generally in the form of coils & inside these muffles objects are kept for heating either for laboratory or industrial purposes. these muffles are made in different Square/ rectangular dimensions . Hitemp Muffels are thin walled for quicker heating. These are rodust in constructions Highly thermal shock resistant.     Rectangular Muffles (Unequal Sizes) Size (Inches) 3 x 4 x 9 3 x 4 x 10 3 x 4 x 15 3 x 4 x 18 4 x 5 x 12 4 x 6 x 12 4 x 7 x 10 4 x 8 x 12 5 x 7 x 14 5 x 7 x 19 6 x 8 x 13 Rectangular Muffles (Equal Sizes) Size (Inches) 4 x 4 x 4 4 x 4 x 6 4 x 4 x 9 5 x 5 x 10 5 x 5 x 12 6 x 6 x 12 7 x 7 x 15 7 x 7 x 19 8 x 8 x 12 8 x 8 x 18 9 x 9 x 12 9 x 9 x 18 10 x 10 x 12 10 x 10 x 15

	GROOVED REFRACTORIES Grooved refractories are mainly used in High temperature muffle furnaces. The heating coils made out of kanthal / Nircrome wire coils in U Shapes are placed in the groove of the refractories. Higher temperature in these furnaces is achieved as objects are heated directly by radiation . Hitemp Grooved refractories are thin walled & light weight for faster heating . By using Hitemp Grooved refractories peak temperature is attained in almost 1/4th the time as compared to conventional grooved refractories available in the market.These are robust in constructions Highly thermal shock resistant.

Laboratory Ceramic Products

Hitemp Combustion Boats are used in the estimation of carbon in steel samples. The sample of steel drilling is taken in a combustion boat and placed inside a tube furnace maintained at 1300 deg to 1400 deg & oxygen is passed over it which combines with carbon of the steel & CO2 is estimated.
