Ultra-low Temperature Freezers SUPERIOR SAMPLE PROTECTION Pull Down Test at 20°C Ambient Fast Pull Down • Pull down time is the time required to bring down the temperature of the ULT freezer from ambient to the set temperature. • Esco Lexicon® has a short pull down time which signifies an efficient refrigeration system*. Temperature Recovery After 1 Minute Door Opening Fast temperature recovery after door opening • Esco Lexicon® recovers temperature in minutes following a 1 min. door opening*. Fast recovery in temperature ensures integrity of stored samples. Uniformity Test at -80°C Cycle...

Ultra-low Temperature Freezers Large Reserve Capacity • Reserve capacity test records the lowest temperature the freezer is able to sustain when a heat source is placed in the freezer. This resembles real life situations when hot samples are placed in the freezer. The lower the temperature the freezer can sustain, the higher chance the freezer can maintain the set temperature when warm samples are placed in the freezer. • Esco reserve capacity surpasses that of all major brands tested below. BTU Reserve Average of 16 Probes** -63 Thermo Scientific Revco ULT2586-10-D, 220V, 60Hz Thermo...

Ultra-low Temperature Freezers Intelligent Design Effective Cooling Technology HeatRecycler™ Technology allows efficient recycling of the heat generated by the system. This reduces power consumption and prolongs the life of the freezer. Mullion Heater • Two additional “heat exchangers” to channel heat energy. • “Mullion heater” recycles excess heat from 1st stage compressor to heat up main door gasket. This prevents ice from forming on the gasket and provides for easy door closing. • 2-Stage cascade refrigeration system. • Two fans are employed to draw consistent airflow from the front to...
