ESCO Lexicon ® II - Absolute Reliability:
- Esco used the industry-approved High Accelerated Life Test (HALT) to stress test a large number of Lexicon Freezers under extreme conditions. Lexicon freezers have passed these extreme stress tests to ensure an optimized design to protect your precious samples.
- In accordance with ANSI/ASHRAE 72-2005 and ARI 1200-2006/2008 guidelines and tested by UL, DNS USA validated third party testing lab,
- The Esco Lexicon ULT Freezer surpassed the performance of 5 major competitors with lower energy consumption, superior cabinet performance (as measured by warm-up time) and demonstrated greater BTU cold storage capacity. .
- Esco Lexicon ® II Ultra Low Temperature ULT Freezer - Superior performance, lower energy costs, better protection.
III. ULT Esco Lexicon ® II Freezer - Quality Ingredients
- All freezer components have been selected from multiple shredding and comparison tests. Only the most reliable ingredients are selected
- Danfoss® compressors are reliable and highly efficient.
- The Danfoss® filter dryer is optimized for HFC refrigerants and uses 100% 3Å molecular sieve cores for high moisture drying capacity. (Moisture equates to a blockage in the system!).
- The condenser is oversized to provide greater cooling capacity.
- Condenser fan produces large air volume and quiet operation.
- The energy-saving high-performance oil separator removes solid contaminants along with excess oil from the system and improves overall system performance.
- A completely seamless encased copper evaporator tube with no joints reduces any potential for field leaks.
- Highly efficient anti-corrosion and pressure-resistant heat exchangers are used for maximum heat transfer.
IV. Esco Lexicon ® II Freezer - Low Energy Consumption
V. Super durable model protection
Super fast heat reduction:
- Pull-down time is the time required to lower the temperature of the ULT freezer from ambient to the set temperature.
- Ultra-low temperature freezer Lexicon ® II - Silver Controller has a short pull-down time indicating an efficient cooling system.
Fast temperature recovery after door opening:
- Esco Lexicon® II restores temperature within minutes of opening the door 1 minute. Fast recovery temperature ensures integrity of stored samples.
Excellent uniform resolution:
- Uniformity test measures the difference between the coldest and warmest points in the freezer when the freezer is operating at the set temperature.
- Esco Lexicon® II has excellent uniformity under normal operating conditions. This ensures that all samples are at the correct temperature.
Safety protection in case of power failure:
- Warm-up time measures the time it takes for the temperature to rise (from -80°C to -50°C) when the power is turned off.
- With a robust insulation system, the Esco Lexicon® II has the best warm-up time among the freezers compared to the right. Slower start-ups during prolonged power outages give users time to make a backup plan.
Large storage capacity:
- The capacity test records the lowest temperature the freezer can maintain when a heat source is placed in the freezer. This is similar to real situations when hot samples are placed in the freezer.
- The lower the temperature that the freezer can maintain, the higher the chance that the freezer will be able to maintain the set temperature when warm samples are placed in the freezer.
- Esco's reserve capacity surpasses all of the major brands tested below.
Low noise operation:
- According to OSHA Occupational Noise Exposure Regulation 1910.95, workplace sound levels must fall below 90 dBA for employees working 8 hours/day.
- Total laboratory noise is highly dependent on the equipment that generates the greatest amount of noise.
- The Esco Lexicon® II Ultra Low Freezer has a noise level of approximately 56 dBA. This ensures a quiet and pleasant working environment for laboratory users.
- Embed thermocouple in foam for easy field troubleshooting.
- The filter dryer is located on deck for easy replacement.
- The hinges and latches of the main door can be adjusted.
- The condenser filter is conveniently located in front of the freezer compartment. This allows easy access for inspection, cleaning and/or alteration.
- Warranty 5 years for compressor, 5 years for whole system.
