which signiﬁes an efﬁcient refrigeration

system*.

Warm-uptimefrom-80°Cto-50°C**

• Warm-up time measures the time taken for temperature to rise up

(from -80°C to -50°C) when the power is interrupted.

• With a robust insulation system in place, Esco Lexicon® has the best

warm-up time among the freezers compared on the right*. Slower

warm-up during an extended power failure buys the user time for

carrying out a back-up plan.
