Ultra-Low-Temperature Freezer
ST-Series
The ColdFAST ST series is an advanced solution for the storage of samples and materials in laboratories and research facilities.
With its innovative S-TwinDrive cooling system, which is equipped with two inverter compressors, it ensures a more balanced temperature and maximum energy efficiency. This system offers the highest level of protection for your samples: should one system fail unexpectedly, the other system can maintain the refrigerator at around -75°C to preserve the integrity of your samples.
The ColdFAST ST series is available in two sizes: 530 litres and 780 litres. This provides sufficient space for a wide range of samples and materials, while the focus is clearly on energy efficiency, reliability and safety.
Two high-performance cooling systems:
The two highly efficient cooling systems operate independently of each other. If one system fails, the other can still maintain the temperature at -75℃, ensuring maximum safety and reliability.
Frequency conversion technology:
Frequency conversion technology is used to control the speed of the compressor in real time by adjusting the output frequency. This ensures a balanced temperature and saves energy at the same time.
Applicable for different power supply environments:
DW-HL530 ultra-low temperature freezer can work normally under various power supply environments such as 110V60Hz, 220V50Hz, 220V60Hz, etc.
The compressors ensure a stable ambient temperature of -86℃, which enables efficient sample storage. Extremely labour-saving: An ergonomic handle, a smooth running rail and a high-precision pressure relief valve make opening and closing the door effortless.
3 interior partitions allow the storage area to be divided into 4 levels for convenient sample placement. 4 inner doors (optional 2) reduce icing caused by opening the door. Stainless steel (SUS304) interior material is durable and easy to clean. Equipped with 4 heavy-duty castors and 2 levelling feet to facilitate the movement and fixation of the appliance.

Highlights:
- Adjustable 3 stainless steel shelves with inner door and double silicone seal
- The fans have extremely durable bearings
- The low-noise direct cooling circuit with suspension frame and sound-insulating compartment have a low-noise fan that minimises the noise generated by the freezer as a whole. This means that the ST series only produces a maximum noise level of 54.4 Db(A)
- Housing insulation with vacuum panels: foamed in polyurethane, 130 mm thick
- Inner housing with rounded corners for easy cleaning
- 4 universal castors and 2 levelling feet for easy movement and fixing
- Remote alarm monitoring including over-temperature alarm, under-temperature alarm, sensor error, battery discharge, high ambient temperature, power failure, etc.
- 10" HD touch screen with user-friendly interface
- USB port for reading out temperature data
- Keypad lock and password access prevent unauthorised access and operation
- Best recovery time on the market (30 min with door open for 1 min)
- Painted sheet steel housing
