Machine structure and material:
A) within the box material: SUS# 304 stainless steel,
B) carton material: stainless steel plate, iron electrostatic painting.
C) thermal insulation material: high-density rock wool.
D) heater: spiral tubular heater, a 380 v 6 kw
Calculation of air ventilation rate formula:
3590 (X, Y) N: ventilation per hour X: ventilation power consumption (W)
N = Y: when no ventilation power consumption (W) V: the Windows volume (g/cm3)
* D * V delta T D: air density (g/cm3) in the delta T: box inside and outside temperature difference (℃)
