Design Solution

For a 35kW level II enclosure:• 11 pieces are to be cut from received

board• Installed into walls/doors• Installed above generator and around

exhaust system

Insulation board dimensions

Cutting/Forming

Done with circular saws 57.5 feet of cutting per enclosure Ventilation is required to eliminate spread

of dust

Insulation of door panels

Insulation of exhaust area

Elimination of perforated steel

Exhaust box installation

Insulation block

Perforated steel

Small bolts

Thickness will remain the same

Thermal conductivity of expanded perlite: .85 Btu in/hr ft2 °F

Thermal conductivity of mineral wool:1.06 Btu in/hr ft2 °F

Same thickness will be used Thermal insulation will improve

Thermal conductivity

*Assuming a heat flow of 3000 Btu/hr

∆T = 735 °F

• For mineral wool with k = 1.06 Btu in/hr ft2 °F

∆T = 590 °F
