Insulation Blankets

Tempco offers a line of Modular Insulating Blankets designed to contain the heat generated by industrial elements in various applications thereby conserving both the energy necessary to generate the heat and to cool the ambient environment.

To determine Simply measure the outside diameter of your heater bands and the width between thermocouples. The distance between thermocouples is critical because the modular blankets are sized to fit between them. To insulate an 8" width you might utilize a series of blankets for instance a 2" and 6" part.

Example

* The length of the plastic injection machine
barrel to insulate is 48".

* From the hopper end the thermocouple breaks needed are at 8" 18" 28" 38" 46" and 48".
This would give insulation distances of 8" 10" 10" 10" 8" and 2".

For the (2) 8" distances use two 4" blankets each

For the (3) 10" distances use one 4" and one 6" blanket each.

For the 2" distance use one 2" blanket

To summarize the total requirement is: one 2" blanket seven 4" blankets three 6" blankets

How to Determine Potential Savings

1. Determine:
* Barrel length
* Diameter of barrel over heaters
* Operating temperature

2. Determine barrel surface area (sq. ft.)
by the following formula:
Circumference = 2pR=pD

Area (sq. ft.) = Circumference (in.) x Barrel Length (in.)
1.44

3. Calculate Heat Losses:
* Referring to the Heat Loss for Barrels chart determine heat losses with and without insulation at operating temperature
* Multiply heat loss value (watts/sq. ft.) without insulation by barrel surface area (sq. ft.)
* Multiply heat loss value (watts/sq. ft.) with insulation by barrel surface area (sq. ft.)

Determine Savings:
* Subtract total heat loss with insulation from heat loss without insulation.
* Divide difference by 1000 to determine KWH savings.

Determine yearly savings:
(KWH saved) x (KWH rate) x (running hours per day)
x (days per week ) x (52 weeks per year )
