Ultra-Low Temperature Freezer 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® II recovers temperature in minutes following a 1 minute door opening. Fast recovery in temperature ensures integrity of stored samples. Uniformity Test at -80°C Cycle...

Ultra-Low Temperature Freezer 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 • According to OSHA 1910.95 Occupational Noise Exposure...

Ultra-Low Temperature Freezer 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 • 2-Stage cascade refrigeration system. • Two additional “heat exchangers” to channel heat energy. • Two fans are employed to draw consistent airflow from the front to the back of the freezer to cool the condenser. • “Mullion heater” recycles excess heat from 1st stage compressor to heat up main door gasket. This prevents ice from forming on...
